Description

TECHNICAL FIELD

[0002] The temperature of plate is very important in the process of hot rough rolling mill rolling plate. It determines the reduction of each pass, and also determines the final performance of plate. Suitable temperature can improve the plasticity of plate, making it easier to deform, so that rolling can be carried out under lower pressure, reducing the power required for rolling equipment.
