Question :Why control rolling technology can improve the mechanical performance of steel ?
Answer:
Controlled rolling is fine grains as the main line of rolling method, it is well known that the grain size of steel, the more bulky, not only its low plasticity, and strength and hardness is very poor.So fine grains of steel strength and toughness are strengthened, and the controlled rolling is used in a variety of means to make the rolling out of the finished product is a product of grain refinement and therefore can improve its mechanical properties.
