Ukuveliswa okuphumelelayo kunye nokusebenzayo kombhobho okanye umbhobho ngumbandela wokuphucula iinxalenye ze-10,000, kubandakanywa nokugcinwa kwezixhobo.Ngamalungu amaninzi ashukumayo kulo lonke uhlobo lwesisila kunye nesixhobo ngasinye se-peripheral, ukulandela ishedyuli yogcino olucetyisiweyo lomenzi ngumceli mngeni.Ifoto: T&H Lemont Inc.
Inqaku lomhleli.Eli licandelo lokuqala loluhlu olunamacandelo amabini ekuphuculeni ukusebenza kwetyhubhu.Funda inxalenye yesibini.
Ukwenziwa kweemveliso ze-tubular ngumsebenzi onzima naphantsi kwezona meko zilungileyo.Imizi-mveliso intsonkothile, ifuna ukulungiswa rhoqo kwaye, kuxhomekeke kwinto abayivelisayo, ukhuphiswano luqatha.Abavelisi abaninzi bemibhobho yentsimbi baphantsi koxinzelelo olukhulu lokwandisa ixesha lokunyusa ukuze kwandiswe ingeniso ngelixa beshiya ixesha elincinane elixabisekileyo lolondolozo olucwangcisiweyo.
Iimeko kwishishini namhlanje azilona zilungileyo.Iindleko zezinto eziphathekayo ziphezulu ngokuhlekisayo, kwaye ukuhanjiswa ngokuyinxenye akuqhelekanga.Ngoku kunanini na ngaphambili, abavelisi bemibhobho kufuneka bandise ixesha eliphezulu kunye nokunciphisa i-scrap, kwaye ukufumana ukuhanjiswa ngokuyinxenye kuthetha amaxesha amafutshane emveliso.Ukubaleka okufutshane kuthetha utshintsho oluthe kratya, olungekuko ukusetyenziswa kakuhle kwexesha okanye umsebenzi.
“Ixesha libalulekile kule mihla,” utsho uMark Prasek, uMphathi weNtengiso yeTubing yaseMntla Melika kunye neTubing kwi-EFD Induction.
Iingxoxo neengcaphephe zeshishini malunga neengcebiso kunye nezicwangciso zokufumana okuninzi kwilinge lakho zityhila imixholo ephindaphindiweyo:
Ukuqhuba isityalo ngencopho yokuphumelela kuthetha ukwenza izinto ezininzi, uninzi lwazo zinxibelelana, ngoko ke ukwenza ngcono ukusebenza kwezityalo akusoloko kulula.Isicatshulwa esidumileyo sowayesakuba ngumbhali wemihlathi kwiThe Tube & Pipe Journal uBud Graham sinikela ingcaciso ethile: “Isila sisakhiwo sesixhobo sokusila.”Ukwazi ukuba isixhobo ngasinye senza ntoni, sisebenza njani, kwaye isixhobo ngasinye sisebenzisana njani nabanye malunga nesithathu sendlela eya empumelelweni.Ukuqinisekisa ukuba yonke into iyaxhaswa kwaye ilungelelanisiwe yenye enye yesithathu.Isithathu sokugqibela sinikezelwe kwiinkqubo zoqeqesho lwabaqhubi, izicwangciso zokusombulula iingxaki kunye neenkqubo ezithile zokusebenza ezizodwa kumbhobho ngamnye okanye umenzi wombhobho.
Ingqwalasela yokuqala yokusebenza kakuhle kwezityalo ayinanto yakwenza nomzi-mveliso.Le mathiriyeli ekrwada, ifumana okuninzi kumatshini wokungqusha, kuthetha ukufumana okuninzi kuyo yonke ikhoyili efakwa kwindawo yokusila.Iqala ngesigqibo sokuthenga.
ubude bekhoyili.“Izingqusho zemibhobho zisebenza kakuhle xa iikhoyili zinde kangangoko kunokwenzeka,” utsho uNelson Abbey, umlawuli weAbbey Products e-Fives Bronx Inc. Ukusebenza ngeeroli ezimfutshane kuthetha ukuphatha iincam ezininzi.Isiphelo ngasinye somqulu sifuna i-butt weld, kwaye i-butt yeld nganye yenza i-scrap.
Ubunzima apha kukuba ezona khoyili zinde zinokuthengiswa ngaphezulu, ngelixa iikhoyili ezimfutshane zinokufumaneka ngexabiso elingcono.I-arhente yokuthenga inokufuna ukonga imali, kodwa ayisiyiyo imbono yabantu abakwimveliso leyo.Phantse wonke umntu oqhuba umzi-mveliso uya kuvuma ukuba umahluko wexabiso kufuneka ube mkhulu ukuhlawulela ilahleko yemveliso eyayanyaniswa nokuvalwa kweplanti okongeziweyo.
Olunye uqwalaselo, uAbby uthi, kumthamo we-decoiler kunye nayo nayiphi na eminye imiqobo ekungeneni kokugaya.Kusenokuba yimfuneko ukutyala imali kwisixhobo sokufaka esinamandla ngakumbi ukuphatha imiqulu emikhulu, enzima ngakumbi ukuze uthathe ithuba lokuthenga imiqulu emikhulu.
Ukusika kukwangumba, nokuba ukusika kwenziwa ngaphakathi okanye kusenziwa ngaphandle.I-Slitter rewinder inobunzima obuninzi kunye nedayamitha abanokusingatha, ngoko ke umdlalo ofanelekileyo phakathi kwe-roll kunye ne-slitter rewinder ibalulekile ekwandiseni imveliso.
Ngaloo ndlela, kukusebenzisana kwezinto ezine: ubungakanani kunye nobunzima bomqulu, ububanzi obufunekayo be-slitter, imveliso ye-slitter kunye namandla esixhobo sokufaka.
Roll ububanzi kunye nemeko.Ihamba ngaphandle kokutsho kwivenkile ukuba imiqulu kufuneka ibe ububanzi obuchanekileyo kunye nobukhulu obuchanekileyo ukuvelisa imveliso, kodwa iimpazamo ziyenzeka.Abaqhubi besixhobo sokungqusha banokuhlala behlawula ngaphantsi okanye ngaphezulu kobubanzi bomtya, kodwa lo ngumbandela wesidanga.Vala ingqalelo kububanzi be-slit complex ibalulekile.
Umda wemeko yentsimbi yentsimbi nayo yinto ebaluleke kakhulu.NgokukaMichael Strand, umongameli we-T&H Lemont, ukusebenza komphetho okungaguqukiyo ngaphandle kwe-burrs okanye nakuphi na ukungangqinelani kubalulekile ekugcineni i-weld engaguqukiyo kubo bonke ubude bomcu.Ukujija kokuqala, ukukhulula i-longitudinal kunye nokubuyisela umva kwakhona kusebenza.Iikhoyili ezingaphathwanga ngononophelo ziyakwazi uku-arc, okuyingxaki.Inkqubo yokuyila, ephuhliswa ziinjineli eziqengqelekayo, iqala ngomcu osicaba, hayi ogobileyo.
ukuqwalaselwa kwezixhobo."Uyilo oluhle lokungunda lukhulisa imveliso," utshilo uStan Green, umphathi jikelele we-SST Forming Roll Inc., eqaphela ukuba akukho sicwangciso sokwenza ityhubhu enye, kwaye ke akukho sicwangciso soyilo sokubumba esinye.Ababoneleli bezixhobo ze-roller bayahluka kwaye iindlela zokucubungula umbhobho ziyahluka, ngoko ke iimveliso zabo ziyahluka.Isivuno sikwahlukile.
"I-radius ye-roller surface iguquka rhoqo, ngoko ke isantya sokujikeleza kwesixhobo sitshintsha phezu kwendawo yonke yesixhobo," watsho.Kakade ke, umbhobho udlula kwindawo yokusila ngesantya esinye kuphela.Ngoko ke, ukuyila kunokuchaphazela isivuno.Wongeze ukuba uyilo olulambathayo luchitha imathiriyeli xa isixhobo sisesitsha kwaye siba sibi ngakumbi njengoko isixhobo sinxiba.
Kwezo nkampani zingaboneleli ngoqeqesho kunye nokugcinwa, ukuphuhlisa isicwangciso sokuphucula ukusebenza kwezityalo kuqala ngeziseko.
"Kungakhathaliseki ukuba luhlobo luni lwesityalo kunye nento eyivelisayo, zonke izityalo zinezinto ezimbini ezifanayo - abaqhubi kunye neenkqubo zokusebenza," kusho u-Abbey.Ukuqhuba eli ziko ngeyona ndlela ibalaseleyo kuxhomekeke kuqeqesho olusemgangathweni kunye nokuthotyelwa kwemigaqo ebhaliweyo, utshilo.Ukungahambelani kuqeqesho kukhokelela kulwahlulo ekusetheni nasekuxazululeni iingxaki.
Ukufumana okuninzi kwiplanti, umsebenzisi ngamnye kufuneka asebenzise ukuseta okungaguquguqukiyo kunye neenkqubo zokusombulula ingxaki, umqhubi ukuya kumqhubi kunye nokutshintsha kwishift.Naziphi na iiyantlukwano ngokwenkqubo zihlala zibandakanya ukungaqondani, imikhwa emibi, ukwenza lula, kunye neendlela zokusebenza.Oku kuhlala kukhokelela kubunzima kulawulo olusebenzayo lweshishini.Ezi ngxaki zinokuba zezasekhaya okanye zenzeke xa umsebenzi oqeqeshiweyo eqeshwe kumntu okhuphisana naye kodwa umthombo awubalulekanga.Ukuhambelana ngundoqo, kubandakanywa nabaqhubi abazisa amava.
“Kuthatha iminyaka ukuphuhlisa umatshini wokusila wemibhobho, kwaye ngenene awunako ukuxhomekeka kwigeneric, inkqubo elinganayo yonke into,” utshilo uStrand."Inkampani nganye idinga inkqubo yoqeqesho elungiselelwe iplanti kunye nokusebenza kwayo."
"Izitshixo ezintathu zokusebenza ngokufanelekileyo kukugcinwa komatshini, ukugcinwa kwezinto ezisetyenziswayo kunye nokulinganisa," kusho uDan Ventura, umongameli weVentura & Associates.“Lo matshini unamalungu amaninzi ashukumayo – nokuba sisingqusho ngokwawo okanye iperipherals kwindawo yokungena okanye yokuphuma, itafile yomdaniso okanye nantoni na – ukugcinwa rhoqo kubalulekile ukuwugcina ukwimeko ephezulu.”
UStrand wavuma.Uthi: “Yonke le nto iqala ngenkqubo yokukhusela.“Oku kunika elona thuba lilungileyo lomsebenzi womzi-mveliso onengeniso.Ukuba umenzi wombhobho uphendula kuphela kwiimeko ezingxamisekileyo, akulawuleki.Kuxhomekeke kwingxaki elandelayo. ”
“Zonke izixhobo ezikwiplanti kufuneka zihlengahlengiswe,” utshilo uVentura.Ngaphandle koko iifektri ziya kubulalana.
"Kwiimeko ezininzi, xa imiqulu idlula ubomi babo obuluncedo, iyaqina kwaye ekugqibeleni iphuke," utshilo uVentura.
“Ukuba ii-windrows azigcinwa zikwimeko entle ngokulungiswa rhoqo, kuya kufika imini apho baya kufuna ukulungiswa okungxamisekileyo,” utshilo uVentura.Uthi, ukuba izixhobo bezityeshelwa, bekuya kufuneka kususwe izinto eziphindwe kabini ukuya kwezintathu ukuze zilungiswe kunoko.Kwakhona kuthatha ixesha elide kwaye kubiza ngaphezulu.
UStrand waphawula ukuba utyalo-mali kwizixhobo zokuxhasa i-backup kunokunceda ukukhusela iimeko ezingxamisekileyo.Ukuba isixhobo sisetyenziswa rhoqo kwimitsi emide, kuya kufuneka iinxalenye ezininzi ezisecaleni kunesixhobo esingafane sisetyenziswe kugqatso olufutshane.Izakhono zesixhobo nazo zichaphazela umgangatho wokulindela.Iimbambo zinokugqabhuka kwisixhobo esinembambo kwaye i-welding rollers inikezela ekushiseni kwegumbi le-welding, iingxaki ezingakhathazi ukwenza kunye nokulinganisa ii-roller.
"Ukugcinwa rhoqo kulungile kwizixhobo, kwaye ukulungelelaniswa okufanelekileyo kulungile kwimveliso eyenzayo," watsho.Ukuba abahoywa, abasebenzi basemizi-mveliso baya kuchitha ixesha elininzi bezama ukubamba.Ixesha elinokuchithwa ekudaleni imveliso ekumgangatho ophezulu efunwa kwimarike.Ezi zinto zimbini zibaluleke kakhulu, kodwa zihlala zingahoywa okanye zingahoywa, kangangokuba iVentura ikholelwa ukuba ibonelela ngelona thuba lilungileyo lokufumana okuninzi kwisityalo, ukwandisa imveliso, kunye nokunciphisa inkcitho.
I-Ventura ilinganisa ukugcinwa kwee-mill kunye nezinto ezisetyenziswayo kunye nokugcinwa kwezithuthi.Akukho mntu uya kuqhuba imoto amashumi amawaka eekhilomitha phakathi kokutshintsha kweoli kunye nokuvuthela itayara.Oku kuya kukhokelela kulungiso oluxabisa kakhulu okanye kwiingozi, nakwizityalo ezingakhathalelwanga kakuhle.
Ukujongwa rhoqo kwezixhobo emva kokusungulwa ngakunye kuyafuneka, utshilo.Izixhobo zokuhlola zinokutyhila iingxaki ezinjenge-microcracks.Ukuchonga umonakalo onjalo ngokukhawuleza emva kokuba isixhobo sisuswe kumatshini, kunokuba sifakwe ngaphambi kokuba sifakwe kwipasi elilandelayo, kuvumela ixesha elingakumbi lokuvelisa isixhobo sokutshintsha.
“Ezinye iinkampani bezisebenza ngokwesiqhelo ngexesha lokuvalwa okucwangcisiweyo,” utshilo uGreene.Wayesazi ukuba kuya kuba nzima ukuhlangabezana nexesha elicwangcisiweyo lokuphumla ngamaxesha anjalo, kodwa waphawula ukuba kwakuyingozi kakhulu.Iinkampani ezithumela ngenqanawa kunye neelori zinomthwalo omninzi okanye azinabasebenzi abaneleyo, okanye zombini, ngoko ke ukuhanjiswa akwenziwa ngexesha kwezi ntsuku.
"Ukuba kukho into ephukile kumzi-mveliso kwaye kufuneka u-odole into entsha, uza kwenza ntoni ukuze uziswe?"– wabuza.Ewe, ukuhanjiswa komoya kuhlala kunokwenzeka, kodwa oku kunokunyusa iindleko zokuhanjiswa.
Ukugcinwa kwee-mills kunye ne-rolls akukhona nje ngokulandela isicwangciso sokulondoloza, kodwa kunye nokulungelelanisa isicwangciso sokulondoloza kunye nesicwangciso semveliso.
Ububanzi kunye nobunzulu bamava kubalulekile kuzo zontathu iinkalo - ukusebenza, ukulungisa iingxaki kunye nokugcinwa.UWarren Whitman, usekela mongameli wecandelo leshishini le-T&H Lemont's Die and Die, uthi iinkampani ezinefektri yombhobho enye okanye ezimbini ezisetyenziselwa zona zihlala zinabantu abambalwa bokugcina ilitye lokusila kwaye bafe.Nokuba abasebenzi bezolondolozo banolwazi, amasebe amancinci anomda omncinci wamava xa kuthelekiswa namasebe amakhulu olondolozo, ebeka abasebenzi abancinci emngciphekweni.Ukuba inkampani ayinalo isebe lobunjineli, isebe lenkonzo kufuneka lixazulule kwaye lilungise ngokwalo.
NgokukaStrand, uqeqesho lwabasebenzi bokusebenza nololongo lubaluleke kakhulu ngoku kunangaphambili.Amaza omhlala-phantsi anxulunyaniswa nokuguga kwabantwana kuthetha ukuba uninzi lolwazi lwezizwe olwakhe lwanceda iinkampani ukuba ziqhubele phambili nokuhla luyancipha.Ngelixa abaninzi abavelisi bemibhobho basenakho ukuthembela kwiingcebiso kunye nesikhokelo sababoneleli bezixhobo zokusebenza, nala mava awakabi makhulu njengoko ebenjalo kwaye aya encipha.
Inkqubo ye-welding ibaluleke kakhulu njengayo nayiphi na enye inkqubo eyenzeka ekwenziweni kombhobho okanye umbhobho, kwaye indima yomatshini wokudibanisa ayinakujongelwa phantsi.
Welding induction.“Namhlanje, malunga nesibini kwisithathu seeodolo zethu zezokubuyisela kwakhona,” utshilo uPrasek.Badla ngokuthatha indawo yokuwelda ezindala, ezinengxaki.Okwangoku, i-output yeyona nto iqhubayo. "
Ngokutsho kwakhe, abantu abaninzi bawela emva kweebhola ezisibhozo ngenxa yokuba i-raw yaphuma emva kwexesha.Wathi: “Ngokuqhelekileyo, xa umatshini ufika ekugqibeleni, umtshisi uyahamba.Inani elimangalisayo labenzi bombhobho kunye nemibhobho bade basebenzise oomatshini abasekelwe kubuchwepheshe betyhubhu yevacuum, okuthetha ukuba basebenzisa oomatshini abaneminyaka engama-30 ubuncinane.Ulwazi ekugcinweni koomatshini abanjalo alukho lukhulu, kwaye kunzima ukufumana iityhubhu ezitshintshileyo ngokwazo.
Ingxaki yabavelisi betyhubhu kunye netyhubhu abasazisebenzisayo yindlela abaguga ngayo.Azisileli ngokwentlekele, kodwa zithomalalisa ngokucothayo.Esinye isisombululo kukusebenzisa ubushushu obuncinci be-welding kunye nokunciphisa isantya se-rolling Mill ukubuyisela, okunokuthi kuphephe ngokulula iindleko zenkunzi yokutyala imali kwizixhobo ezitsha.Oku kudala ubuxoki bokuba yonke into ilungile.
NgokukaPrasek, utyalo-mali kumthombo wamandla omtsha we-induction welding inokunciphisa kakhulu ukusetyenziswa kwamandla kwiziko.Amanye amazwe, ngakumbi lawo anabemi abaninzi kunye neegridi ezixineneyo, anikezela ngezaphulelo zesisa emva kokuthenga izixhobo ezonga amandla.Wongeze ukuba inkuthazo yesibini yokutyalomali kwimveliso emitsha yinto enokwenzeka yesakhono amatsha okuvelisa.
Ngokuqhelekileyo, i-welder entsha iyasebenza kakhulu kunomdala kwaye inokugcina amawaka eedola ngokuhambisa amandla amaninzi ngaphandle kokuphuculwa kwamandla, "kusho uPrasek.
Ukulungelelaniswa kwe-inductor kunye ne-resistor nayo ibalulekile.UJohn Holderman, umphathi jikelele we-EHE Consumables, uthi i-telecoil enobungakanani kunye efakwe ngokufanelekileyo inendawo efanelekileyo ngokumalunga nevili le-welding kwaye ifuna ukucoceka okufanelekileyo kunye nokuqhubekayo malunga nombhobho.Ukuba isetwe ngokungalunganga, ikhoyili iya kusilela kwangethuba.
Umsebenzi we-blocker ulula - uvala ukuhamba kombane, uqondise ekupheleni komcu - kwaye njengayo yonke enye into kwi-rolling Mill, ukubeka indawo kubalulekile, utsho.Indawo echanekileyo yimiphezulu ye-weld, kodwa oku akukona kuphela ukuqwalaselwa.Ukufakela kubalulekile.Ukuba idityaniswe mandrel ukuba akukho mandla ngokwaneleyo, indawo bollard angatshintsha kwaye okunene uya kutsala ID ecaleni emazantsi umbhobho.
Ukuthatha ithuba leentsingiselo kwizinto ezityiwayo ze-welding, iikhonsepthi zokwahlulahlula iikhoyili zinokuba nefuthe elibalulekileyo kwixesha lezityalo.
"Ii-mill ze-diameter ezinkulu ziye zasebenzisa uyilo lwe-serpentine ixesha elide," utshilo u-Holderman."Ukutshintsha i-coil ye-induction eyakhelwe-ngaphakathi idinga ukusika umbhobho, ukubuyisela i-coil, kwaye uphinde uyinqumle kumatshini wokugaya," watsho.Uyilo lwekhoyili enamacandelo amabini lugcina lonke elo xesha kunye nomzamo.
“Zazisetyenziswa kumatshini omkhulu wokusila ngaphandle kwemfuneko, kodwa ukusebenzisa lo mgaqo kwiikhoyili ezincinci kufuna ubunjineli obufanelekileyo,” utshilo.Abavelisi abananto yakusebenza ngayo."I-reel encinci, eneziqwenga ezibini ine-hardware ekhethekileyo kunye nentaba ehlakaniphile," watsho.
Ngokumalunga nenkqubo yokupholisa i-impedance, abavelisi bemibhobho kunye nemibhobho baneendlela ezimbini eziphambili zokukhetha: inkqubo yokupholisa esembindini yeplanti, okanye inkqubo yonikezelo lwamanzi eyahlukileyo, enokubiza imali eninzi.
“Kungcono ukupholisa isixhasi ngesipholisi esicocekileyo,” utshilo uHolderman.Ukuza kuthi ga ngoku, utyalo-mali oluncinci kwinkqubo ekhethekileyo yokucoca i-impedance ye-rolling mill inokunyusa kakhulu ubomi be-impedance.
Isipholisi siqhele ukusetyenziswa kwizithinteli, kodwa into yokupholisa inokuchola intsimbi entle.Ngaphandle kwazo zonke iinzame zokubambisa amasuntswana amancinci kwisihluzo esisembindini okanye ukusebenzisa inkqubo yemagnethi esembindini ukubambisa, abanye baye bagqitha kwaye bangena kwisithinteli.Le asiyondawo yomgubo wentsimbi.
"Bafudumeza kwibala lokungeniswa kwaye batshise ngomzimba ochasayo kunye ne-ferrite, ebangela ukungaphumeleli kwangaphambi kwexesha okulandelwa kukuvalwa kwendawo yokumelana," utshilo uHaldeman."Bakwakha kwi-telecoil kwaye ekugqibeleni babangele umonakalo we-arc."
