Kukho iindlela ezintandathu eziphambili zokusetyenzwa kweimibhobho engenamthungo (SMLS):

1. Indlela yokugaya: Sebenzisa umatshini wokugaya i-swage ukuze wolule isiphelo okanye inxalenye yombhobho ukunciphisa ububanzi bangaphandle. Oomatshini be-swage abasetyenziswa ngokuqhelekileyo babandakanya uhlobo olujikelezayo, uhlobo lwentonga yokudibanisa, kunye nohlobo lwe-roller.

2. Indlela yokunyathela: Sebenzisa i-core tapered kumatshini wokubhoboza ukwandisa i-tube ekupheleni kobukhulu obufunekayo kunye nokuma.

3. Indlela ye-roller: faka i-core kwi-tube, kwaye utyhale i-circumference yangaphandle kunye ne-roller ye-round edge processing.
4. Indlela yokuqengqeleka: Ngokubanzi, akukho mandrel efunekayo, kwaye ifanelekile kumphetho ongaphakathi ongqukuva wetyhubhu ezishinyeneyo.
5. Indlela yokugoba: Kukho iindlela ezintathu ezisetyenziswa ngokuqhelekileyo, enye indlela ibizwa ngokuba yindlela yokwandisa, enye ibizwa ngokuba yi-stamping, kwaye indlela yesithathu yi-roller. Kukho ii-roller ezi-3-4, ii-roller ezimbini ezisisigxina, kunye ne-roller enye yokulungelelanisa. Ngomgca we-roll esisigxina, umbhobho ogqityiweyo unzima.
6. Indlela ye-Bulging: Enye kukubeka irabha ngaphakathi kombhobho, kwaye usebenzise i-punch ukuqinisa phezulu ukwenza umbhobho uphume; enye indlela i-hydraulic bulging, igcwalisa umbindi wombhobho ngolwelo, kwaye uxinzelelo lolwelo lukhupha umbhobho kwimilo oyifunayo. Uninzi lwemilo kunye nesiphumo semibhobho yethati zezona ndlela zingcono.

Ngokwamanqanaba okushisa ahlukeneyo emibhobho yentsimbi engenamthungo, imibhobho yentsimbi engenamthungo yahlulwe ngokusebenza okubandayo kunye nokusebenza okushushu.

I-Hot-rolled ingenamthungoumbhobho wensimbi: fudumeza i-billet yetyhubhu engqukuva ukuya kubushushu obuthile kuqala, emva koko uyigqobhoze, emva koko uye kwi-rolling eqhubekayo okanye i-extrusion, emva koko uye kuhluba kunye nokulinganisa, emva koko uphole phantsi kwi-tube ye-billet kwaye ulungelelanise, kwaye ekugqibeleni kuya kuqhutywa. iinkqubo ezinjengomfuniselo wokubona iziphene, ukumakishwa, kunye nogcino.

Ingqele ingenamthungoumbhobho wensimbi: ukufudumeza, ukugqobhoza, i-heading, i-annealing, pickling, i-oiling, ukuqengqeleka okubandayo, ityhubhu ye-billet, unyango lobushushu, ukulungiswa, ukufumanisa impazamo kunye nezinye iinkqubo ze-tube billet ejikelezayo.
