Uthini umahluko phakathi kombhobho wentsimbi eshushu esongiweyo kunye nombhobho wentsimbi ongenamthungo oqengqiwe?Ngaba umbhobho oqhelekileyo wentsimbi ongenamthungo oshushu waqengqeleka umthungo wentsimbi?
Uninzi lwemibhobho yentsimbi engenamthungo eqengqelekayo incinci, kwaye uninzi lwemibhobho yentsimbi engenamthungo eqengqelekayo ikwizinga elikhulu.Ukuchaneka kombhobho wentsimbi ongenamthungo oqengqelekayo ungaphezulu kunombhobho wentsimbi ongenamthungo oqengqelekayo, kwaye ixabiso likwaphezulu kunombhobho wentsimbi ongenamthungo.
Ngenxa yeenkqubo ezahlukeneyo zokuvelisa, imibhobho yentsimbi engenamthungo yahlulahlulwe yaba yimibhobho yentsimbi eshushu eqengqelekayo (ekhutshiweyo) engenamthungo kunye nemibhobho yentsimbi engenamthungo (eqengqelekisiweyo).Iibhobho ezibandayo (eziqengqelekayo) zihlulwe zibe yimibhobho ejikelezileyo kunye nemibhobho yeprofayili ekhethekileyo.
1) Ukusetyenziswa ngeendlela ezahlukeneyo Imibhobho engenamthungo e-Hot-rolled yahlulwe yaba yimibhobho yentsimbi eqhelekileyo, imibhobho yentsimbi yebhoyila yoxinzelelo oluphantsi noluphakathi, imibhobho yentsimbi yebhoyila yoxinzelelo oluphezulu, imibhobho yentsimbi yealloyi, imibhobho yentsimbi engenasici, imibhobho yokuqhekeka kweoyile, imibhobho yentsimbi yejoloji kunye nabanye.iityhubhu zentsimbi..Imibhobho yentsimbi epholileyo eqengqelekayo (ekudayila) yahlulwe yaba yimibhobho yentsimbi eqhelekileyo, imibhobho yentsimbi ephantsi kunye noxinzelelo oluphakathi, imibhobho yentsimbi yebhoyila yoxinzelelo oluphezulu, imibhobho yentsimbi yealloyi, imibhobho yentsimbi engatyiwayo, imibhobho eqhekeka i-oyile, eminye imibhobho yentsimbi kunye nemibhobho yekhabhoni..Imibhobho intsimbi kabini-endonga, ingxubevange Imibhobho steel obhityileyo-endonga, imibhobho iprofayile intsimbi.
2) Ububanzi bangaphandle beesayizi ezahlukeneyo zemibhobho engenamthungo eyenziwe eshushu ngokuqhelekileyo ingaphezulu kwe-32mm, kwaye ubukhulu bodonga yi-2.5-75mm.Ubukhulu bombhobho ongenamthungo obuqengqelekayo bunokuya kuthi ga kwi-6mm, kwaye ububanzi bodonga bube yi-0.25mm.Ububanzi bangaphandle bombhobho obhityileyo bunokufikelela kwi-5mm, kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm.Ukuqengqeleka okubandayo kunomgangatho ophezulu wokuchaneka kunokuqengqeleka okushushu.
3) Ukwahluka kwenkqubo 1. Iprofayili yensimbi epholileyo inokuvumela ukugoba kwendawo yecandelo, elingasebenzisa ngokupheleleyo umthamo wokuthwala intsimbi egobileyo, ngelixa iphrofayili yensimbi eshushu eshushu ayivumeli ukugquma kwendawo yecandelo..
2. Izizathu zokuvela koxinzelelo olushiyekileyo kwiimveliso ezishushu kunye neemveliso ezibandayo zihlukile, ngoko ke ukusabalalisa phezu kwecandelo kukwahluke kakhulu.Ukusasazwa koxinzelelo olushiyekileyo kwi-cross section ye-cold-formed thin-walled steel steel i-curvilinear, kwaye ukuhanjiswa kweengcinezelo eziseleyo kwi-cross section of hot-rolled or welded steel ifilimu.
3. Ubunzima be-torsional rigidity yensimbi eshushu eshushu iphezulu kuneyentsimbi epholileyo, ngoko ke ukusebenza kwe-torsional yensimbi eshushu ingcono kuneyentsimbi epholileyo.
I-4) Iintlobo ezahlukeneyo ze-Advantages kunye ne-Disvantages I-Cold rolled i-seamless imibhobho ngamacwecwe ensimbi okanye iintambo zetsimbi ezicutshungulwa kwiintlobo ezahlukeneyo zetsimbi ngokudweba okubandayo, ukugoba okubandayo, umzobo obandayo, njl.
Izinto eziluncedo: isantya sokubumba ngokukhawuleza, imveliso ephezulu, akukho monakalo kwisambatho, ukukwazi ukuvelisa iimilo ezahlukeneyo ezinqamlezayo ngokweemfuno zeemeko zokusetyenziswa;ukuqengqeleka ebandayo kunokubangela deformation yeplastiki enkulu yentsimbi, ngaloo ndlela ukwandisa amandla isivuno.intsimbi.
Ukungalungi: 1. Nangona kungekho ngqungquthela ye-thermoplastic ngexesha lenkqubo yokuqulunqa, kusekho uxinzelelo olushiyekileyo kwicandelo, elichaphazela ngokungenakuphepheka iimpawu zentsimbi eziqhelekileyo kunye neendawo zentsimbi 2. Isitayela sentsimbi epholileyo epholileyo ngokubanzi icandelo elivulekileyo, elinokuthi lithintele ngokubanzi kunye neempawu ze-buckling zendawo. yenza ukuba ukuqina kwecandelo ukukhulula i-torsion ibephantsi.Kulula ukujijwa ekugobeni, kulula ukugoba kunye nokugoba kuxinzelelo, kwaye inokumelana nokungahambi kakuhle kwe-torsional 3. Ubukhulu bodonga lwamashiti ensimbi abandayo buncinci, kwaye ii-angles ezidibeneyo zamaphepha aziqini, ngoko amandla okumelana. imithwalo egxininisiweyo yendawo ibuthathaka.
Imibhobho eshushu esongwayo engenamthungo yimibhobho ebandayo eqengqelekayo engenamthungo.Imibhobho epholileyo engenamthungo iqengqeleke ngaphantsi kweqondo lobushushu le-recrystallization, ngelixa i-hot-rolled seamless pipes iqengqeleka ngaphezulu kweqondo lobushushu le-recrystallization.
Izinto eziluncedo: Inokutshabalalisa isakhiwo sokuphosa i-ingot yensimbi, icokise iinkozo zetsimbi, isuse iziphene zesakhiwo, yenza ulwakhiwo lwentsimbi lube lukhuni, kwaye luphucule iimpawu zomatshini.Olu phuculo lubonakaliswa ikakhulu kwicala lokuhamba, ukwenzela ukuba insimbi iyeke ukuba yi-isotropic kwinqanaba elithile;amaqamza, iintanda kunye nokuqina okwenziwa ngexesha lokusalwa nako kunokudityaniswa kubushushu obuphezulu kunye noxinzelelo oluphezulu.
Ukungalungi: 1. Emva kokutshisa okutshisayo, ukufakwa kwe-non-metallic inclusions (ikakhulukazi i-sulfides kunye ne-oxides, kunye ne-silicates) ngaphakathi kweentsimbi zixinzelelwe kumaphepha amancinci kunye ne-delaminate (i-interlayer).I-delamination iyancipha kakhulu iipropati ezithintekayo zentsimbi kwicala lobunzima, kwaye i-interlaminar fracture ingenzeka xa i-weld iyancipha.I-deformation yendawo ebangelwa yi-shrinkage ye-weld ihlala ifikelela amaxesha amaninzi ukuguqulwa kwamandla esivuno, okungaphezulu kakhulu kunokuguqulwa okubangelwa ngumthwalo;
2. Uxinzelelo olushiyekileyo olubangelwa kukupholisa okungalinganiyo.Uxinzelelo olushiyekileyo luxinzelelo lwangaphakathi lokuzilinganisa ngaphandle kwamandla angaphandle.Olu xinzelelo olushiyekileyo lukhona kumacandelo entsimbi ashushu aqengqelekayo amacandelo ahlukeneyo anqamlezayo.Njengomthetho, ubukhulu becala lomnqamlezo weprofayili yensimbi, inkulu uxinzelelo oluseleyo.Nangona uxinzelelo oluseleyo luzilinganisa, lusenomphumo othile ekusebenzeni kwamacandelo ensimbi phantsi kwesenzo samandla angaphandle.Ngokomzekelo, kunokuchaphazela kakubi i-deformation, ukuzinza, kunye nokumelana nokudinwa.
3. Akulula ukulawula ubukhulu kunye nobubanzi becala lentsimbi eshushu.Siqhelene nokwandiswa kwe-thermal kunye nokuncipha.Ngenxa yokuba ekuqaleni, nokuba ubude kunye nobukhulu buhambelana nomgangatho, kuya kubakho umahluko othile ongalunganga emva kokupholisa kokugqibela.Okukhona umahluko ongalunganga, kokukhona ungqingqwa kwaye kokukhona kucace ngakumbi ukusebenza.
