我厂3吨单相无芯工频感应电炉于1973年10月试炉成功并投入生产。该炉主要用于熔化铸铁,亦可用来熔炼铸钢。为了提高炉衬寿命和防止漏炉事故,我厂采用了特制电熔石英和高纯度石英砂的混合料为炉衬材料,采用了双重炉衬和不加粘结剂的干式筑炉法等技术措施,收到了良好的效果。采用上述工艺砌筑的炉衬,熔化铸铁炉龄达155炉。现将我厂采用的炉衬材料及砌炉工艺介绍如下,供参考。一、炉衬材料采用特制的电熔石英和高纯度石英砂的混合料为炉衬的打结材料。天然石英随着温度的变化发生一系列的相
I plant 3 tons of single-phase coreless induction heating furnace in October 1973 trial furnace successfully and put into production. The furnace is mainly used for melting cast iron, can also be used to smelt cast steel. In order to improve the lining life and prevent accidental leakage of the furnace, our factory adopts a mixture of special fused fused silica and high purity quartz sand as the lining material, adopting double furnace lining and dry-laying method without binding agent and other technical measures, Received good results. Using the above process masonry lining, melting cast iron furnace up to 155 furnaces. Now I plant lining materials used in the construction and process described below, for reference. First, the lining material using a special fused quartz and high-purity quartz sand mixture lining materials for the lining. Natural quartz with temperature changes occur a series of phases
