Pamusoro peCold Rolled Steel Coil
Iyo inotonhora yakakungurutswa coil inogadzirwa inopisa yakakungurutswa coil. Mukuita kutonhora kwakakungurutswa, iyo inopisa yakakungurutswa coil inokungurutswa pazasi tembiricha yerecrystallization, uye simbi inowanzo kukungurutswa inokungurutswa pakamuri tembiricha. Simbi yesimbi ine yakakwira silicon yemukati ine yakaderera brittleness uye yakaderera plasticity, uye inoda kupiswa kusvika 200 ° C isati yatonhorwa. Sezvo iyo inotonhora yakakungurutswa coil isingadziye panguva yekugadzira, hapana chakaremara senge gomba uye iron oxide iyo inowanzo kuwanikwa mukupisa kunopisa, uye kunaka kwepamusoro uye kupera kwakanaka.
