五 矿热炉用途和类别 矿热炉是一类用途广泛、式样众多的电炉。这类电炉多数用来从矿石中制取各种冶金和化工原料,所以叫做矿热炉。炉子的基本结构同炼钢电弧炉相似:下面有一个用耐火材料砌制的炉膛,上面有一根或几根用碳或石墨制成的电极。在工作过程中,电极的下部一般是埋在炉料里面的(参见图一),所以除了电极和炉料间的电弧所产生的热以外,电流通过炉料 Minmetals furnace uses and categories Submerged arc furnace is a wide range of uses, many styles of electric furnace. Most of these furnaces are used to make all kinds of metallurgical and chemical raw materials from the ore, so called the furnace. The basic structure of the furnace is similar to a steel-making electric arc furnace: Below is a furnace of refractory-lined material with one or more electrodes made of carbon or graphite. During operation, the lower part of the electrode is usually buried in the charge (see Figure 1), so in addition to the heat generated by the arc between the electrode and the charge, the current through the charge
