INkqubo Jikelele yokuHamba kweHot-rolled Steel Pipe engenamthungo

Inkqubo yokuvelisa imibhobho yentsimbi engenamthungo eshushu ibandakanya ukulungiswa kwebillet phambi kokuqengqeleka, ukufudumeza umbhobho webillet, ukugqobhoza, ukuqengqeleka, ubungakanani kunye nokunciphisa, ukupholisa umbhobho wentsimbi, intloko kunye nomsila wentsimbi, ukwahlula, ukolula, ukufumanisa impazamo, ukuhlolwa ngesandla, ukutshiza. ukumakisha nokuprinta , ukupakishwa kweBundle kunye nezinye iinkqubo ezisisiseko.Kule mihla, kukho iinkqubo ezintathu eziphambili zoguquko ekuvelisweni kwemibhobho yentsimbi engenamthungo eqengqelekayo: ukugqobhoza, ukuqengqeleka kwemibhobho, kunye nokulinganisa kunye nokunciphisa.Iinjongo zenkqubo efanelekileyo kunye neemfuno zezi zilandelayo.

1. ukugqobhoza

Ukugqobhoza kukugqobhoza ityhubhu eqinileyo kwicapillary enomngxuma.Isixhobo sibizwa ngokuba ngumatshini wokugqobhoza: Iimfuno zenkqubo yokugqobhoza zezi:
(1) Qinisekisa ukuba ubukhulu bodonga lwe-capillary edlulayo bufana, i-ovality incinci, kwaye ukuchaneka kobungakanani bejometri buphezulu;
(2) Umphezulu wangaphakathi nangaphandle wombhobho we-capillary ugudileyo, kwaye akufuneki kubekho iziphene ezifana nokukrala, ukugoba, ukuqhekeka, njl.;
(3) Kufuneka kubekho isantya esihambelanayo sokugqobhoza kunye nomjikelo wokuziqhelanisa nesingqisho semveliso yeyunithi yonke, ukuze iqondo lobushushu lokugqibela lombhobho we-capillary likwazi ukuhlangabezana neemfuno ze-tube rolling Mill.

2. Ityhubhu eqengqelekayo

Ityhubhu eqengqelekayo kukucinezela ityhubhu ye-capillary enemingxuma engqindilili kwityhubhu yenkunkuma enodonga olucekethekileyo ukuze kuzuzwe ubungakanani obufunekayo bobushushu kunye nokufana kombhobho ogqityiweyo.Oko kukuthi, ubukhulu bodonga lombhobho wenkunkuma kule nkqubo buchongwa ngokwexabiso lokunciphisa inkqubo elandelayo kunye nefomula ye-empirical yokucubungula ubuninzi bodonga.Esi sixhobo sibizwa ngokuba yi-pipe rolling Mill.Iimfuno zenkqubo yokuqengqeleka ityhubhu zezi: (1) Xa ityhubhu ye-capillary enodonga olungqingqwa ijikwa ibe ngumbhobho wenkunkuma obhityileyo (ulwandiso lodonga oluncitshisiweyo), kuyafuneka kuqala ukuba kuqinisekiswe ukuba ityhubhu yenkunkuma inobukhulu obuphezulu bodonga. ukufana;
(2) Umbhobho wenkunkuma unomgangatho olungileyo wangaphakathi nangaphandle.Ukukhethwa kombhobho we-tube kunye nokulungelelaniswa okufanelekileyo kwe-deformation yayo kunye nenkqubo yokubhoboza yinto ephambili ekunqumeni umgangatho, umphumo kunye nezibonakaliso zobugcisa kunye nezoqoqosho zeyunithi.

3. Ukucuthwa kwedayamitha esisigxina (kubandakanywa nokunciphisa uxinzelelo)

Umsebenzi oyintloko wokulinganisa kunye nokunciphisa ukuphelisa umehluko kububanzi obungaphandle bombhobho wenkunkuma obangelwa yinkqubo yangaphambili yokuguqa, ukwenzela ukuba kuphuculwe ukuchaneka kobubanzi obungaphandle kunye nokujikeleza kombhobho ogqityiweyo ogqityiweyo.Ukunciphisa ububanzi kukunciphisa ubukhulu bombhobho omkhulu ukuya kubukhulu obufunekayo kunye nokuchaneka.Ukunciphisa uxinzelelo kukunciphisa i-diameter phantsi kwesenzo soxinzelelo lwesakhelo sangaphambili nasemva, kunye nokunciphisa udonga ngaxeshanye.Izixhobo ezisetyenziselwa ukulinganisa kunye nokunciphisa ngumatshini wokulinganisa (ukunciphisa).Iimfuno zenkqubo yokulinganisa kunye nokunciphisa zezi:
(1) Ukuphumeza injongo yokulinganisa phantsi kweemeko zomlinganiselo othile wokunciphisa uwonke kunye nezinga lokunciphisa elincinane kwisakhelo esinye;
(2) Inokuqonda umsebenzi wokusebenzisa ityhubhu enye yobukhulu obungenanto ukuvelisa ubukhulu obuninzi beetyhubhu ezigqityiweyo;
(3) Ukuphucula ngakumbi umgangatho wangaphandle wombhobho wentsimbi.
