(1) Umahluko phakathi kokusebenza okushushu nokusebenza okubandayo: ukuqengqeleka okushushu kukusebenza okushushu, kwaye umzobo obandayo ngumsebenzi obandayo.Umahluko ophambili: ukuqengqeleka okutshisayo kuqengqeleka ngaphezulu kweqondo lobushushu le-recrystallization, ukuqengqeleka okubandayo kuqengqeleka ngaphantsi kweqondo lobushushu;Ukuqengqeleka okubandayo ngamanye amaxesha kushushu, kodwa iqondo lobushushu liphantsi ngokwentelekiso, kuba ukusetyenzwa kwenzeka emva kokubanda okuqengqelekayo Hard, ukuba iimfuno zokwenza izinto ziphezulu ngokwentelekiso, kufuneka zihlanjululwe.

I-cold-rolled and hot-rolled are general plates or profiles, lo gama i-cold-drawn iyi-cylindrical cross-section ingcingo ngokubanzi.Ukongeza, iipleyiti ezishushu ezishushu ziqhelekile ziintsimbi ezinomxholo ophezulu we-alloy kunye namandla aphezulu, ngelixa iintsimbi ezipholileyo zinekhabhoni ephantsi kunye ne-low-alloy steels.I-Cold rolling inokunyusa amandla kwaye iqinisekise umgangatho ophezulu wezinto eziphathekayo.

Umahluko phakathi kombhobho wentsimbi ongenamthungo otsalwa ngokubanda kunye nombhobho wentsimbi ongenamthungo oqengqiwe wahlukile kulowo weepleyiti.

Imibhobho yentsimbi engenamthungo yahlulwe yaba yimibhobho yentsimbi eshushu eqengqelekayo (eyongeziweyo) nengenamthungo kunye nemibhobho yentsimbi etsalwa ngokubanda (eqengqiwe) ngenxa yeenkqubo ezahlukeneyo zokwenza izinto.

Imibhobho yentsimbi ezotyiweyo ebandayo ngokubanzi ifuna izotywe izihlandlo ezininzi, kwaye kufuneka kubekho okuhambelanayo okuthomalalisa uxinzelelo phakathi komzobo ngamnye ukuqinisekisa inkqubela egudileyo yomzobo olandelayo obandayo.Ukusuka kwinkangeleko, imibhobho yentsimbi engenamthungo eqengqelekayo isoloko incinci ngobubanzi, kwaye imibhobho yentsimbi engenamthungo eshushu eqengqelekayo idla ngokuba nobubanzi obukhulu.Ukuchaneka kombhobho wensimbi ongenamthungo opholileyo uphezulu kunombhobho wensimbi ongenamthungo oshushu, kwaye ixabiso likwaphezulu kunelo lombhobho wensimbi ongenamthungo oshushu.Imibhobho ebandayo engenamthungo etsalwa ngokubanda ikholisa ukuba nomgangatho omncinci, ubukhulu becala ngaphantsi kwe-127mm, ngakumbi ukuchaneka kwedayamitha yangaphandle yemibhobho ebandayo etsalwa ngokubanda engenamthungo iphezulu kakhulu, kwaye ubude bemibhobho ebandayo engenamthungo bufutshane kunolo lwemibhobho eshushu eqengqelekayo engenamthungo.Ngokumalunga nobukhulu bodonga, imibhobho engenamthungo etsalwa ngokubanda ifana kakhulu kunemibhobho engenamthungo eqengqelekayo.
