炼钢电弧炉炉衬在高温下工作。由于弧光的幅射、炉渣对炉衬的化学侵蚀以及冶炼过程中熔池温度急剧变化等因素的影响,使炉衬的使用寿命降低。对于间断炼钢的炉子,冷热状态的突变,加速了炉衬的损坏。因此,采用结构合理的炉墙,是电冶炼生产技术的重要环节。在长期实践中,利用我厂钢管头多的优势,采用镁砂管—水冷挂渣炉墙,并用废电极制成电极砖代替出钢口水箱。这种结构的联合炉墙,砌筑简便,安全可靠,深受广大操作者的欢迎。一、镁砂管的使用镁砂管是联合炉墙的主体部份,是影响炉墙使用
Steelmaking arc furnace lining work at high temperatures. The service life of the lining is reduced due to the influence of the arc radiation, the chemical attack of the slag on the lining and the rapid change of the temperature of the molten pool in the smelting process. For intermittent steelmaking furnaces, sudden changes in hot and cold conditions accelerate the failure of the lining. Therefore, the use of a reasonable structure of the furnace wall, is an important part of the smelting production technology. In long-term practice, the use of our factory more than the advantages of steel pipe, the use of magnesia pipe - water-cooled hanging slag furnace wall and electrode made of waste electrode instead of tap water tank. This structure of the combined furnace wall, masonry simple, safe and reliable, welcomed by the majority of operators. First, the use of magnesium tube Magnesia tube is the main part of the combined furnace wall is the use of furnace wall
