Roller industry development trends
During the working process of the roll, it mainly bears the effects of dynamic and static loads, wear and temperature changes during rolling. Therefore, it is required to have good strength and toughness to resist the impact load during the working process and high hardness. And excellent wear resistance to reduce consumption during use and reduce rolling production costs. The comprehensive performance of rolls is closely related to their material composition and preparation process. With the advent of advanced rolling mills and efficient rolling technology, rolling production lines are developing in the direction of large-scale, high-speed and automation, making the rolls, as the core equipment of steel rolling, The usage conditions have become more demanding. The performance of the rolls directly affects the production efficiency of the rolling mill, the surface quality of the rolled material and the cost of rolling.
