摘　　要：文章介绍了弹簧钢板60Si2MnA的生产工艺流程以及相应的工艺参数,并且通过相应的冷却工艺(4~9℃/s)控制,可以得到产品需要的组织,该组织保证了产品的力学性能。结果表明,以包钢现有的装备及工艺,在合适的铁水条件及其他原料条件下,选择恰当的工艺参数,可以生产出抗拉强度不低于1050 MPa、延伸率不小于13%的60Si2MnA弹簧钢板。另外,通过控制加热炉的气氛,使高碳钢60Si2MnA钢表面脱碳层厚度控制较好,仅为国标GB/T 1222—2016要求的18%。In this paper,the production technology process and technological parameters of spring steel plate 60Si2MnA are introduced as well as the microstructure that products need could be obtained through corresponding cooling technique(4~9℃/s)control,which guarantees the mechanical properties of products.The results showed that the spring steel plate 60Si2MnA with tensile strength not less than 1050 MPa and elongation not less than 13%could be manufactured through choosing appropriate process parameters with the existing equipment and processes under appropriate conditions of liquid iron and other raw materials.Moreover,the thickness of decarburized layer on the surface of high carbon steel 60Si2MnA is controlled better,which is 18%of requirements of national standard GB/T 1222—2016 through controlling the atmosphere of heating furnace.
