Kukho iintlobo ezimbini zemibhobho yentsimbi engenamthungo: i-hot-rolled and cold-rolled (dial) imibhobho yentsimbi engenamthungo.
Imibhobho yentsimbi engenamthungo eshushu eqengqelekayo yahlulwe ngokwemibhobho yentsimbi ngokubanzi, imibhobho yentsimbi yebhoyila yoxinzelelo oluphantsi naphakathi, imibhobho yentsimbi yebhoyila yoxinzelelo oluphezulu, imibhobho yentsimbi yealloyi, imibhobho yokuqhekeka kwepetroleum, imibhobho yentsimbi yejoloji kunye neminye imibhobho yentsimbi.
Ukongeza kwimibhobho yentsimbi eqhelekileyo, uxinzelelo oluphantsi noluphakathi lwemibhobho yentsimbi, imibhobho yensimbi yoxinzelelo oluphezulu, imibhobho yentsimbi yealloyi, imibhobho eqhekekileyo yepetroleum, kunye neminye imibhobho yentsimbi, imibhobho yentsimbi epholileyo eqengqelekayo (yokudaya) iquka intsimbi enekhabhoni ebhityileyo. imibhobho, i-alloy thin-walled steel pipes, iprofayili yensimbi yeprofayili, njl.
Idayamitha yangaphandle yombhobho ongenamthungo oqengqelekayo ngokuqhelekileyo mkhulu kune-32mm, kwaye ubukhulu bodonga yi-2.5-75mm. Ububanzi bombhobho wensimbi ongenamthungo obandayo bunokufikelela kwi-6mm, kwaye ubukhulu bodonga bunokufikelela kwi-0.25mm. Ububanzi bangaphandle bombhobho obhityileyo bunokufikelela kwi-5mm, kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm. Ukuqengqeleka okubandayo kunomgangatho ophezulu wokuchaneka kunokuqengqeleka okushushu.
Imibhobho yentsimbi engenamthungo yokusetyenziswa ngokubanzi: yenziwe ngentsimbi ekumgangatho ophezulu wekhabhoni efana ne-10, 20, 30, 35, 45, 16Mn, 5MnV kunye nezinye iintsimbi eziphantsi kwealloy okanye i-40Cr, 30CrMnSi, 45Mn2, 40MnB kunye nezinye iintsimbi zealloy. zishushu ziqengqiwe okanye ziqengqeleke kubanda.
10, 20 kunye neminye imibhobho yentsimbi ephantsi yekhabhoni engenamthungo isetyenziswa ikakhulu kwimibhobho yokuhambisa ulwelo. Iityhubhu ezingenamthungo ezenziwe ngentsimbi yekhabhoni ephakathi enje nge-45 kunye ne-40Cr zisetyenziselwa ukwenza iindawo ezinomatshini, ezinje ngeendawo ezinoxinzelelo lweemoto kunye neetrektara. Ngokuqhelekileyo, iibhobho zentsimbi ezingenamthungo zisetyenziselwa ukuqinisekisa amandla kunye neemvavanyo zokubethelela. Imibhobho yentsimbi eshushu ihanjiswa kwindawo eshushu okanye ephethwe ngubushushu; imibhobho yentsimbi epholileyo ihanjiswa kwisimo sokushisa.
