我厂有公称容量为1吨和1.5吨电弧炉各一台,设备的主要参数如下:炉顶用高铝砖砌制,炉底与炉衬为沥青镁砂整块捣制而成。由于生产任务的特点与限电要求,我厂电炉只在夜间生产,冷炉熔炼的比例约占1/2～1/3。生产钢种较多,其中高 C_r,N_i 含量的耐热合金钢占总产量30～50%,由于铸件重量不等,有时不允许采用多装与超装操作,从节电看,上述因素均为不利。近两年我们对电炉炼钢降低电耗问题做了一些工作,取得一定成绩,
Our factory has a nominal capacity of 1 tons and 1.5 tons of electric arc furnace each one, the main parameters of the equipment are as follows: Top of the furnace with high-alumina brick, bottom and lining for the asphalt magnesia from the whole block ramming. Due to the characteristics of the production tasks and power requirements, our factory electric furnace is only produced at night, the proportion of smelting furnace accounts for about 1/2 ~ 1/3. Production of steel more, of which high C_r, N_i content of heat-resistant alloy steel accounts for 30 to 50% of the total output, due to the casting weight range, and sometimes do not allow the use of multi-loaded and super loading operation, from the power saving, the above factors are As unfavorable. In the past two years, we have done some work on electric furnace steelmaking to reduce electricity consumption and achieved certain achievements.
