Ngokweenkqubo ezahlukeneyo zokuvelisa, imibhobho yentsimbi engenamthungo inokwahlulwa ibe yimibhobho yentsimbi eshushu eqengqelekayo, imibhobho yentsimbi engenamthungo eyandisiweyo, kunye nemibhobho yentsimbi etsalwa ngokubanda engenamthungo.Iindidi ezine zeetyhubhu zentsimbi ezingenamthungo eziqengqelekayo ezibandayo.

Umbhobho wentsimbi ongenamthungo oshushu oqengqelekayo yintsimbi engqukuva egqojozwe kwityhubhu engenanto ngumatshini wokugqobhoza ize idlule kwisixhobo sokusila esitshisayo ukuseta ityhubhu engenanto kwingcaciso engaphandle kwedayamitha ukuba yenziwe ibe yi-hot-rolled ingenamthungo. ityhubhu yentsimbi.Inkqubo ilula kwaye ixabiso liphantsi, kodwa ukuchaneka kwe-dimensional ayiphezulu.

Imibhobho yentsimbi eshushu eyandisiweyo engenamthungo yenziwa ngokusebenzisa izikhewu zemibhobho yentsimbi engenamthungo okanye imibhobho egqityiweyo yentsimbi engenamthungo ukuba itshiswe kwiqondo lobushushu elingaphezu kwe-1050 degrees kwiziko lombane elinentloko ye-alloy core ukwandisa ukuya kububanzi obuthile bangaphandle ngaphakathi.Emva kokwandiswa kumbhobho wensimbi owandisiweyo ongenamthungo, ubukhulu bodonga buncinci kunempahla ekrwada, ubude bufutshane, kwaye ububanzi bangaphandle bukhulu.

Umbhobho wentsimbi ongenamthungo otsaliweyo (i-astm a53) ngumbhobho wentsimbi ongenamthungo owakhiwa ngokuzoba umbhobho wentsimbi ongenamthungo ongenanto okanye ogqityiweyo umbhobho wentsimbi ongenamthungo ngokungunda komatshini wokuzoba obandayo.Ihambelana nenkqubo yokwandisa eshushu.Umbhobho ogqityiweyo ozotyiweyo ude kunezinto eziluhlaza , Ubunzima bodonga buncinci, kwaye ububanzi bangaphandle buncinci.Inkqubo yokudweba ayifuni ukufudumeza, kwaye inokuqulunqwa kwiqondo lokushisa, kwaye inokuphinda ifakwe kwakhona.Ngamanye amaxesha akuyomfuneko ukuba anneal.

Inkqubo ebandayo yokuqengqeleka iphinda iveliswe kwiqondo lobushushu begumbi njengenkqubo yokuzoba ebandayo, kodwa ilitye lokusila elibandayo lahlukile kumatshini wokuzoba abandayo.Umatshini wokudweba obandayo wenziwa ngumbumba, kwaye i-cold rolling mill yenziwa ngokuthe ngcembe yi-mold, ngoko ke inkqubo ebandayo ebandayo iyaveliswa Iyacotha kunemveliso yenkqubo ebandayo.
