轧辊是轧钢生产的重要工具。轧辊质量严重影响轧钢的生产率和生产成本。大跃进以来,轧辊不耐磨和易折断的矛盾在鞍钢各轧钢厂显得尤为突出。因此,鞍山钢铁公司和清华大学焊接教研组合作进行了堆焊钢轧辊的研究。堆焊钢轧辊最本质的特点是利用双金属的优越性,使轧辊的强度和表面耐磨性同时提高,因而有可能成倍地增加轧辊使用寿命和大大减少断辊事故。同时也有可 Roll is an important tool for rolling production. Roll quality seriously affects the productivity and production costs of rolled steel. Since the Great Leap Forward, the contradiction between the non-wear-resistant rolls and the easy-break rolls has become particularly prominent in the rolling mills in Anshan Iron and Steel. Therefore, Anshan Iron and Steel Company and Tsinghua University Welding Research Group conducted a study of the roller surfacing. The most essential feature of the surfacing steel roll is the use of bimetal superiority, which simultaneously increases the strength and surface wear resistance of the roll, thereby potentially doubling the service life of the roll and greatly reducing the number of broken rolls.
