通过对应用了过滤器后的中间包、铸坯的纯净度进行分析,对CaO过滤器在50tT型中间包上的应用效果进行评价。用物理流动模型与数值模拟对钢液的流动进行模拟。结果表明:中间包大型夹杂物去除效率提高了17.1%,死区比例减小了8%。
By analyzing the tundish after the application of the filter, the purity of slab was analyzed, and the application effect of CaO filter on 50 tT tundish was evaluated. The flow of molten steel is simulated by physical flow model and numerical simulation. The results show that the removal efficiency of large inclusions in tundish increased by 17.1% and the proportion of dead zone decreased by 8%.
