为确保高速浇铸而无漏钢,必须搞清楚初期凝固坯壳与结晶器壁之问结晶器保护渣的润滑状况,同时这一点也是控制弯月面处凝固壳的形成,保证板坯表面质量的基本前提。使用模拟方法计算了结晶器振动过程中,结晶器壁与坯壳间隙间流进的结晶器保护渣量,并分析了与板坯表面振痕深度相关的坯壳变形。模型计算结果与连铸板坯的表面质量吻合很好。
In order to ensure high-speed casting without leakage, we must clarify the early solidification shell and mold wall mold powder mold lubrication, and this point is to control the formation of solidified shell at the meniscus to ensure the surface quality of the slab The basic premise. The amount of mold fluxes flowing in the mold wall and the gap between the mold wall and the shell during the mold oscillation was calculated by the simulation method. The deformation of the shell was analyzed in relation to the depth of vibration on the slab surface. The calculated results are in good agreement with the surface quality of continuous casting slabs.
