一、前言 最近的轧机形式与过去相比,大型化、高速化了,轧制效率高了,轧辊要在苛刻条件下使用,所以人们希望获得性能更好的轧辊。 一般说来,钢材轧辊在使用时,承受轧制应力负荷的热负荷。特别是热轧辊,因为强烈地承受热的影响,所以在工作辊的表面除发生磨损之外,还发生各种各样的损伤。 I. Introduction Recently, the rolling mill has been larger and faster than before. The rolling efficiency is high and the rolls are used under harsh conditions. Therefore, people want to obtain better performance of the rolling mill. In general, the steel roll in use, bear the heat load of the rolling stress load. In particular, since the hot roll is strongly affected by the heat, various damages occur in addition to wear on the surface of the work roll.
