一、中频炉与石墨坩埚反射炉熔炼对比 在熔炼ZQA19-4铜中的铝、铁元素,普遍的方法是将铝锭和铁钉通过石墨坩埚熔化,浇成铝—铁合金块,再配入铜料中,这样的生产方式有以下一些缺点: 1.由于使用铁钉作原料,不仅与其他行业争材料,而且提高了铸件成本。 2.铝锭熔化加入铁钉后,要不时地进行拌搅,以加速熔化,最后还要舀出,劳动强度大。
First, the intermediate frequency furnace and graphite crucible reflex furnace melting contrast ZQA19-4 copper in the melting of aluminum, iron, the general method is to aluminum ingots and nails through the graphite crucible melting, pouring into aluminum - iron alloy block, then with copper Materials, such production methods have the following disadvantages: 1. Due to the use of iron nails as raw materials, not only compete with other industries for materials, but also improve the casting costs. 2. After adding aluminum nails melting nails, from time to time to stir, in order to speed up the melting, and finally scoop out, labor-intensive.
