我厂炼钢车间8~#炉于一九七七年七月创造了碱性白云石砖炉衬81炉的成绩,同年八月又创造了102炉的历史最高水平,是我厂5吨电炉开炉以来的最高炉令。后继出现90炉86炉的炉令,情况见表。从表看出81炉炉令的平均熔化时间1小时59分,全炉冶炼时间3小时38分。102炉平均熔化时间1小时49分,全炉时间3小时22分。90炉的平均冶化时间2小时,全炉时间3小时55分,此届炉令期的总结冶炼时间此过去缩短22分38秒。86炉届炉令全炉冶炼时间为4小时32分,主要
Our plant 8 ~ # furnace in July 1977 created the basic dolomite lining furnace furnace 81 results, in August the same year created the highest level of 102 furnaces, is my factory 5 tons of electric furnace open The highest furnace order since the furnace. Follow-up furnace furnace blast furnace 90 orders 90, the situation shown in the table. The table shows that the average furnace melting furnace 81 hours 1 hour 59 minutes, the furnace smelting time 3 hours 38 minutes. 102 furnace melting time 1 hour and 49 minutes, 3 hours and 22 hours all-furnace time. 90 furnace 2 hours average metallurgical time, furnace time 3 hours and 55 minutes, the summary of this session of the furnace smelting time in the past shortened 22 minutes 38 seconds. 86 stove furnace furnace smelting time is 4 hours 32 minutes, the main
