Umbhobho wentsimbi ongenamthungo oshushu oqengqelekayo ukusuka kumbhobho ukuya kwimveliso ngokubanzi ufuna ukufudumeza ezimbini, ezinetyhubhu enemingxuma phambi nasemva kokufudumeza kunye nokuqengqeleka kwedayamitha yombhobho ongenanto kwindawo yokufudumeza kwangaphambili;ukuveliswa kwe-cold-rolled (ukutsala) xa umbhobho ufuna ukusetyenziswa kwe-annealing ephakathi ukuphelisa uxinzelelo oluseleyo;intsimbi yeemfuno ezithile ezikhethekileyo, ukwenzela ukuba kuphuculwe iimpawu zoomatshini bombhobho wentsimbi kunye nokuphucula umbutho kunye nokusebenza kwenkqubo, kodwa kunye nonyango lwayo lobushushu.Umbhobho oqhelekileyo (umbhobho) wokufudumala ityhubhu iziphene zokufudumeza ngokungalingani, i-oxidation, i-decarbonization, iintanda zokufudumeza, ukushisa, ukutshisa kakhulu.

Ithubhu eqhumayo ngaphambili, kunye nenjongo yayo kukuphucula i-ductility;ukunciphisa insimbi yokumelana ne-deformation;ukubonelela nge-microstructure elungileyo iyaqengqeleka.Kukho isithando somlilo se-annular, isithando somlilo esifudumalayo, iziko elithambekele kwiziko kunye nesithando somlilo esisezantsi semoto.Ukunqongophala kombhobho ububanzi phambi ukufudumeza kwakhona, nto leyo ijolise ukwandisa ubushushu ityhubhu kunye ukunqongophala iyunifomu nokuphucula ductility intsimbi, ukulawula microstructure yayo, ukudala iimeko ezivumayo ukuba umbhobho sizing unina kwaye uqinisekise iimpawu mechanical zentsimbi.Uhlobo oluqhelekileyo lokufudumeza iziko lokunyathela, isithando somlilo esiqhubekayo somlilo, iziko lokutshisa i-oblique, i-inductive reheating oblique.I-Cold-rolled (i-pull) ivuselela ukuqina ngokuyinhloko ukuphelisa, ukunciphisa ukuxhatshazwa kwe-deformation.Isithando somlilo esiqhelekileyo sisetyenziselwa ukufudumeza iziko, isithando somlilo esisezantsi semoto, isithando somlilo esiqhubekayo.Kwimveliso yeetyhubhu zetsimbi ezingenamthungo, i-furnace annular kunye ne-reheating furnace okwangoku isetyenziswa kakhulu;isithando sokufakelwa sombane siyaphuhliswa;iziko lokufudumeza iziko ngenxa yokuba umgangatho awuphezulu, unzima kakhulu kwaye uvame ukupheliswa.Isithando somlilo esiqhubekayo se-roller sisetyenziswa ikakhulu kwi-cold-rolled (ukutsala) unyango lobushushu lwentsimbi;Iziko lemoto elisezantsi lilungele iibhetshi ezincinci, ixesha lonyango lobushushu lide lokufudumeza kunye nokugquma umbhobho wentsimbi oshinyeneyo;igesi ekhuselayo eqhubekayo roller eziko isetyenziswa ikakhulu kumphezulu intsimbi kufuna unyango ubushushu kunye nentsimbi ebandayo egqityiweyo ngaphandle oxidation (tsalo) ngexesha pickling inkqubo annealing.
