为获得更高的经济效益,铝铸造行业在选择熔炼炉时要考虑使用能量的种类。本文对所涉及能量的价格及消耗进行了比较。鉴于对未来能量价格的预测,正如以往经验所表明的,对其经济效益作评价所进行的这些比较还是不够的。在熔炼厂操作人员的出版物里,表现出对价格结构以及在此前提下炉型选择标准的理论基础产生了极大兴趣。从本报告可推测因烧损所致金属损耗的意义所在。 In order to obtain higher economic benefits, the aluminum foundry industry should consider the type of energy used when choosing a melting furnace. This article compares the price and consumption of energy involved. In the light of the projections of future energy prices, as the previous experience suggests, these comparisons of the economic benefits are not enough. In smelter operators’ publications, there has been a great deal of interest in the theoretical structure of the price structure and of the furnace type selection criteria under this premise. From this report, we can speculate about the significance of metal loss due to burnout.
