I-Hot rolled ihambelana nemimiselo yokubanda, i-cold-rolled ikwiqondo lokushisa eliphantsi kwe-recrystallization ngaphantsi kwe-rolling, kwaye i-hot rolling iqhutyelwa ngaphezu kwe-recrystallization yokushisa.

Izinto eziluncedo:

Ishushu esongwayo singonakalisa i-microstructure ye-ingot yentsimbi, ukulungiswa kweenkozo zekristale zentsimbi, kunye nokuphelisa iziphene ze-microstructure, ukuze umbutho wentsimbi udibanise, uphucule iipropati zoomatshini.Olu phuculo lubonakaliswe kwi-rolling direction, ukwenzela ukuba intsimbi ayisekho kwinqanaba elithile le-isotropic;ukugalela ukwakheka kwamaqamza, iintanda, kunye ne-osteoporosis, phantsi kobushushu obuphezulu kunye noxinzelelo nazo zinokudityaniswa kunye.

Izinto ezingeloncedo:
I-1 Emva kokutshisa okutshisayo, i-nonmetallic inclusions ngaphakathi kwentsimbi (ikakhulukazi i-sulfides kunye ne-oxides, kunye ne-silicate) icinezelwe kwiphepha, i-stratified (laminated) phenomenon ibonakala.Ukumaleko kwentsimbi kwicala elingqindilili ngokusebenza kokutsalwa kuye kwahla kakhulu, kwaye kunokuvela kwi-weld shrinkage interlayer tear.I-Weld shrinkage ebangela uxinzelelo lwasekuhlaleni luhlala lufikelela amaxesha amaninzi isivuno samanqaku, ubunzima bukhulu kakhulu kunomthwalo obangelwayo;
2 Uxinzelelo olushiyekileyo olubangelwa kukupholisa okungalinganiyo.Uxinzelelo olushiyekileyo luxinzelelo lwe-self-phase equilibrium ngokungabikho kwamandla angaphandle, intsimbi eshushu eqengqelekayo ye-cross-sectional inoxinzelelo olushiyekileyo olunjalo Ngokuqhelekileyo i-dimension yecandelo lensimbi likhulu, lukhulu ngakumbi uxinzelelo olushiyekileyo.Uxinzelelo lwe-Residual luyi-self-phase equilibrium, kodwa amalungu ensimbi ekusebenzeni kwamandla angaphandle okanye anempembelelo ethile.Njenge-deformation, ukuzinza, ukuchasana nokukhathala kunokuba kakubi.
3 Iimveliso zetsimbi ezishushu ezishushu, ulawulo olubi lobunzima kunye nobubanzi bomphetho.Siqhelene nokwandiswa kwe-thermal kunye nokucutha, nokuba isiqalo sobushushu obuqengqelekayo bubude obuqhelekileyo, ubukhulu, okanye kuya kubakhona okokugqibela okungalunganga emva kokupholisa, lo mphetho umbi umahluko ombi ububanzi ububanzi onyukayo bomgangatho wokwenziwa komsebenzi. kucace ngakumbi.Ke kwintsimbi enkulu yobubanzi bomphetho wentsimbi, ubukhulu, ubude, i-engile, kunye ne-sideline akukho mthetho ufuna ukuchaneka kakhulu.Intsimbi jikelele eshushu eqengqelekayo, umbhobho webhoyila woxinzelelo oluphantsi nophakathi, imibhobho yebhoyila yoxinzelelo oluphezulu, imibhobho yentsimbi, umbhobho wentsimbi engatyiwa, umbhobho oqhawukayo we-oyile, imibhobho yentsimbi yejoloji kunye neminye imibhobho yentsimbi.
