在构建铸造铝合金熔化热能物理和数学模型的同时,基于现场采集数据进行了定量能耗分析。结果表明,常见集中熔化炉进行铸造铝合金连续熔化时,燃气热能的40.8%用于将炉料熔化成760℃的熔体,33.3%随高温烟气外排,16.5%在熔炼操作过程中通过炉门(盖)辐射和对流散失,7.4%通过炉壳表面散失,2%随炉渣外排。
While constructing the physical and mathematical models of the molten heat energy of cast aluminum alloy, quantitative energy consumption analysis was carried out based on the collected data in the field. The results show that 40.8% of the heat energy of the gas is used to melt the charge to 760 ℃, 33.3% to the high temperature flue gas, and 16.5% to pass through the furnace during the smelting operation Door (cover) radiation and convection loss, 7.4% through the furnace shell surface lost, 2% with the slag discharge.
