江苏省冶金工业最近几年来有较大的发展,特别是650以下的中小型轧机发展尤为迅速,已成为地方轧钢工业的重要力量。目前这类轧机粗轧机架用辊大多使用Mn靠系或Mn—Mo系低合金钢铸钢轧辊。这类轧辊耐磨性低、易断辊、辊耗高、难于满足现代化轧机的要求。目前国外发达国家这类轧机广泛采用高碳铬钼铸钢轧辊。为了适应轧钢工业发 The metallurgical industry in Jiangsu Province has been greatly developed in recent years. Especially the small and medium-sized rolling mills below 650 have developed rapidly and have become an important force in the local rolling industry. At present, most of the rolling mill stands for rolling mills use Mn-based or Mn-Mo-based low-alloy steel casting rolls. Such rolls wear resistance is low, easy to break roller, roller consumption is high, it is difficult to meet the requirements of modern mill. At present, such developed countries widely used high-carbon chromium molybdenum steel rolling mill roll. In order to adapt to the rolling industry hair
