由于铝制品一般是经过对原铝锭的重熔后加工而成,而我国铝工业中大多数厂家重熔铝锭时都是采用油炉或电阻反射炉。这两种炉和有芯工频感应电炉(以下简称有芯炉)相比,有许多不足之处,特别是能源消耗和铝的烧损是当前比较突出的问题。本文想通过对有芯炉的认识和近年在生产中的应用说明有芯炉在铝工业中有值得推广的价值。
Because aluminum products are generally after the remelting of the original aluminum ingot processing, and most of China’s aluminum industry, when the remelting of aluminum ingots are used oil furnace or resistance reflex furnace. There are many shortcomings between these two kinds of furnace and core-frequency power induction furnace (hereinafter referred to as core furnace), especially the energy consumption and the burning of aluminum are the prominent problems at present. In this paper, through the understanding of coffering furnaces and its application in production in recent years, it is demonstrated that cored furnaces are worthy of promotion in the aluminum industry.
