摘　　要：以AlSi7Mg铝合金铸造车轮为研究对象,通过对比低压铸造用传统单室保温炉与新型双室保温炉产品铸造生产及报废情况,研究了新型铸造机双室炉在铝合金车轮铸造生产工艺中的重要作用。研究结果表明:与传统低压铸造用单室保温炉相比较,新型双室保温炉铸造生产的亮面制程产品综合报废率平均低约1.82%,其中轮辐亮面部位夹渣报废率平均低约1.77%;双室保温炉中铝液温度随时间波动小。Taking AlSi7Mg aluminum alloy casting wheels as research object,by comparing the production and scrap of traditional single-chamber and advanced double-chamber holding furnaces for low pressure casting,the important role of the new double-chamber furnace for the casting of aluminum alloy wheels was studied.The results indicate that compared with the traditional single-chamber holding furnace for low-pressure casting,the scrap rate of bright-faced products produced by the casting of the new double-chamber holding furnace is about 1.82%lower,among them,the scrap rate of slag inclusion on the bright face of spokes is about 1.77%lower;The temperature of the aluminum liquid in the double-chamber holding furnace fluctuates little with time.
