摘要
实验研究了150kg真空感应炉冶炼铁铬铝合金铸锭常见缺陷成因分析及改善措施。本文设计了4种不同的实验方案,研究了浇注温度、浇注时间、炉衬使用次数和中间包是否使用过滤器对钢锭表面质量及内部缩孔的影响情况。结果表明,浇注温度为1640℃、浇注时间为0.56 min、中间包使用过滤器、炉衬使用次数越少的条件下钢锭表面质量较好且内部无缩孔缺陷。
This paper studied the cause and the improvement measures of common defects in Fe-Cr-Al alloy ingots smelted by150 kg VIM furnace. Through four experiments, the influence of pouring temperature, pouring time, the lining use times and whether the tundish used a filter are studied on the surface quality and the internal shrinkage. The results show that the surface quality of the ingot is better and there is no shrinkage cavity defect under the condition that the pouring temperature is 1640 ℃,the pouring time is 0.56 min, the lining is used less and the tundish uses the filter.
