通过数据的数学处理 ,找出了熔池深度与锭高和重熔电流间的规律。这一数学模式可用于描述和预示任意重熔电流时的最大熔池深度及随锭高增长熔池深度变化的趋向。熔池的深浅 ,影响金属结晶生长方向改变及夹杂物和气体的去除过程。合理控制重熔电流与熔池深度 ,对改善ESR锭铸态组织和材料品质是有益处的
Through mathematical data processing, we found out the rule of pool depth, ingot height and remelting current. This mathematical model can be used to characterize and predict the maximum melt pool depth at any remelting current and the tendency of the bath depth to change as the ingot increases in height. The depth of the molten pool affects the direction of growth of the metal crystals and the removal of inclusions and gases. Reasonable control of remelting current and bath depth is beneficial for improving the quality of as-cast as-cast tissue and material in ESR ingot
