根据我们实验工厂的生产特点,学习了兄弟单位的经验,自己动手砌筑了一台能兼作熔炼铜、铝合金和干燥型芯的三用炉。近两年的生产实践,说明这种炉子具有不少优点,现作一简要介绍。炉子结构见附图。该炉由一个燃烧室、熔铜和熔铝用两个用埚室、一个铜合金预热熔化室和一个室式干燥炉组成。以无烟煤作为燃料。炉子每次只熔化一种合金(即燃烧室至坩埚室的两条火道同时只开一条)。熔铜时,待熔的铜合金装在预热熔化室中,铜水熔化后,流入 According to the production characteristics of our experimental factory, we learned the experience of our brother unit and built a three-purpose furnace that can double as smelting copper, aluminum alloy and dry core. The past two years of production practice shows that this stove has many advantages, is a brief introduction. Furnace structure see attached map. The furnace consists of a combustion chamber, melting copper and aluminum with two crucible room, a copper alloy preheating melting chamber and a chamber-type drying furnace composition. Anthracite as a fuel. The furnace melts only one alloy at a time (ie, the two fires from the combustion chamber to the crucible chamber open only one at a time). When the copper is melted, the copper alloy to be melted is charged in the preheating melting chamber, and the copper water melts and flows in
