我厂自行设计制造的容量为二吨的无芯工频感应电炉,经过七年多的使用,熔化普通铸铁与合金铸铁四干余炉,一直使用正常,性能稳定。一、主要设计参数见表一; 二、实际生产参数见表二: 三、主要工艺性能分析:1、配料:尽量采用本牌号铸铁的废品作回炉料,由于各元素在熔化过程中变化少,故在确定回炉料的数量后, 配料主要是决定废钢及新生铁的相对比例。实际生产的配料变化范围见表三:
Our factory design and manufacture capacity of two tons of coreless frequency induction furnace, after more than seven years of use, melting ordinary cast iron and alloy cast iron four dry furnace, has been using the normal, stable performance. First, the main design parameters in Table 1; Second, the actual production parameters in Table II: Third, the main process performance analysis: 1, ingredients: try to use the grade cast iron scrap back to the charge, due to changes in the melting of the elements less, Therefore, after the quantity of returned charge is determined, the ingredients mainly determine the relative proportions of scrap and fresh pig iron. The actual range of changes in the production of ingredients in Table 3:
