I-Hot rolled (ipayipi lensimbi elingenamthungo): ithubhu eliyindilinga → ukushisa → ukubhoboza → → ukugoqeka kwamaroli amathathu, ukugoqeka noma ukukhishwa → kuhlukanisiwe → ukusika (noma ukunciphisa) → ukupholisa → ukuhlolwa kwe-hydraulic yokuqondisa (iphutha) → ithegi → isitoreji.

Ishubhu eligoqayo elingenamthungo lezinto zokusetshenziswa liyishubhu eliyindilinga, imibungu yamashubhu idlula emshinini wokusika ukuze isike ukukhula kwezinga cishe imitha elingu-1, futhi ithunyelwe ukushisisa kwesithando somlilo sebhande lokudlulisa.I-Billet ifakwa esithandweni sokushisa, izinga lokushisa lingaba ngu-1200 degrees Celsius.Isibaseli se-hydrogen noma i-acetylene.Ukulawulwa kwezinga lokushisa kwesithando somlilo kubalulekile ukugqoka i-air tube round, ngemva kokukhululwa kwe-puncher yokucindezela.okuyizinto ngokuvamile ezivame kakhulu i-puncher tapered roller punch, ukusebenza kahle kokukhiqiza okuphezulu, ikhwalithi yomkhiqizo, ivolumu enwebekayo enezimbobo, igqoke izinsimbi ezihlukahlukene.Ngemuva kokubhobozwa, ishubhu eliyindilinga bekuyi-three-roll cross rolling, rolling noma extrusion.Ngemuva kokukhipha usayizi wamapayipi.Isigayo sokulinganisa ngokuzungezisa ngesivinini esikhulu sokubhoboza ikhoni ku-punch ye-Billet ukwenza ipayipi lensimbi.Ububanzi bangaphakathi bepayipi lensimbi bunqunywa ubude bobubanzi bangaphandle bomshini wokugaya usayizi.Ngemuva kokulinganisa, ipayipi lensimbi lokungena embhoshongweni wokupholisa ngokupholisa isifutho samanzi, ipayipi lensimbi emva kokupholisa, kuyadingeka ukuba uqondise.Kuthunyelwe ipayipi lokuthutha ngokuqondisa umshini wokuthola insimbi (noma ukuhlolwa kwe-hydrostatic) ukuze kuqhutshwe iphutha langaphakathi.Izinkinga zangaphakathi zamapayipi ensimbi njengokuqhekeka, amabhamuza zizotholwa.Ukuhlolwa kwekhwalithi yamapayipi ensimbi kodwa nangokukhetha okuqinile okwenziwa ngesandla.Ipayipi lensimbi Lokuqondisa Ikhwalithi, Ukuhlola, sebenzisa upende wesifutho enombolweni, usayizi, iqoqo lokukhiqiza.Ngemoto yekhebula elenga endlini yokugcina impahla.
