Advantages of hot rolling

(1) Hot rolling can  reduce the energy consumption and reduce costs significantly. When hot rolled, high plasticity and low deformation resistance of metal can reduce the energy consumption. 

(2) Hot rolling can improve the processing performance of metal and alloy, the casting of the state of the bulky grain breakage, crack healing, significantly reduce or eliminate the casting defects, 
the as-cast into deformation, improve the processing performance of alloy.

(3) Hot rolling usually adopt large ingot casting, rolling, with great not only improves the production efficiency, but also for improving the rolling speed, rolling process of continuous and automation.
