摘要: 应用“射钉法”测试了攀钢2#大方坯连铸典型钢种在工作拉速下凝固末端附近的凝固坯壳厚度,获得了凝固坯壳厚度、凝固末端位置与连铸拉速和冷却强度的关系,为优化连铸工艺,控制连铸坯凝固终点位置和制定合理的轻压下工艺制度提供了重要依据。Abstract: The solidified shell thickness of bloom near the final stage of solidification in the secondary cooling zone on Pangang No.2 continuous bloom caster was measured,by use of the pin-shooting method.On the basis, the relationship between the solidified shell thickness,the final stage of solidification of bloom and casting speed,secondary cooling intensity wag obtained.The research results have provided the important basis for optimizing continuous casting process,controlling the final stage of solidification and establishing reasonable process parameters of soft reduction.
