通过对大量实测数据的分析研究,发现水冷炉壁电弧炉具有不同于镁砂炉壁的散热特征.1) 通过水冷炉壁的小时散热量,随冶炼炉数的增多而缓慢增加;在有限的炉数区间内,小时散热量处于相对稳定状态.2) 通过水冷炉壁的小时散热量,同所选用的水冷块质量关系极大.3) 通过水冷炉壁的小时散热量,同所采用的冶炼方法有关;不氧化法冶炼的小时散热量大于氧化法.被测电炉连续运行了54天,生产了307炉优质钢.观测工作进行了45天.
Through the analysis of a large number of measured data, it has been found that the water-cooled EAF has different heat dissipation characteristics from the magnesia furnace wall.1) The hourly heat dissipation through the water-cooled EAF increases slowly with the increase of the number of smelters; The number of hours in the furnace cooling capacity is relatively stable.2) The hourly heat dissipation through the water-cooled furnace wall is greatly related to the quality of the selected water-cooled block.3) The hourly heat dissipation through the water-cooled furnace wall is the same as that adopted Smelting method; non-oxidizing smelting hour heat dissipation is greater than the oxidation method was tested electric furnace continuous operation for 54 days, producing 307 high-quality steel furnace observation work carried out for 45 days.
