E1辊是1700生产线轧钢生产中的消耗件。轧钢时E1辊直接与轧件接触,需要承受轧制压力、摩擦力等多种力的作用。因此,E1辊在生产中要避免出现辊颈缩松、辊身夹渣、裂纹等缺陷。论述了E1辊的技术要求、化学成分、铸造工艺、工装设计、熔炼浇注工艺、热处理工艺等。新开发的E1辊,硬度、耐磨性高,换辊周期长,因而轧机效率提高,生产成本降低。 The E1 roll is a consumable part in the production of 1700 rolling mill. E1 rolling steel rolling contact with the rolling directly, the need to withstand rolling pressure, friction and other forces. Therefore, E1 roll in the production to avoid roll neck shrinkage, roll body slag, cracks and other defects. The technical requirements, chemical composition, casting process, tooling design, melting pouring process and heat treatment process of E1 roll are discussed. The newly developed E1 roll, high hardness, high wear resistance, long roll change period, so the mill efficiency, lower production costs.
