How often is it? What is the range of temperature in the process of rolling? What is the temperature of the final rolling?
Typically, the temperature decreases gradually during rolling (a small amount of high speed wire has a temperature rise process), usually above 750 degrees, and can reach 600 degrees or even lower
Cold rolling is not consideredThe temperature at which the billet begins to roll (surface) is generally 1000-1150 degrees
The final rolling temperature is the rolling temperature of the last pass, and also the rolling temperature of the rolling pass at the last effective (very small level pass, not an effective rolling pass)
