以 0 8Al钢作为母带 ,H90黄铜作为复合层材料 ,系统地研究了反向凝固复合工艺中浸渍复合时间、铜液的温度以及钢带的预热温度和厚度对黄铜复合层厚度变化的影响规律。研究结果表明 :随浸渍复合时间的增加 ,复合层的厚度变化经历了凝固生长、平衡相持和回熔 3个阶段 ;铜液温度以及钢带预热温度和厚度变化不改变复合层厚度的变化规律 ,但对各阶段的持续时间和复合层的厚度有影响 ;钢带越厚以及铜液的温度和钢带的预热温度越低 ,复合层的厚度越厚
With 0 8Al steel as masterbatch and H90 brass as composite layer material, the effects of impregnation time, temperature of copper liquid and preheating temperature and thickness of strip on the thickness of brass composite layer were studied systematically. The law of influence. The results show that with the increase of impregnation time, the thickness changes of the composite layer have undergone three stages of solidification growth, equilibrium phase holding and meltback; the change of the temperature of the copper liquid and the strip preheating temperature and thickness does not change the thickness of the composite layer , But the duration of each stage and the thickness of the composite layer have an impact; the thicker the strip and the temperature of the molten copper and the lower the preheat temperature of the strip, the thicker the thickness of the composite layer
