下塔吉尔钢铁公司,在设法提高平炉生产能力和使用寿命的过程中,对完善平炉结构和设备、采用机械化手段改进炉子修理系统、提高本厂生产的耐火材料质量与耐火材料的合理重复使用、完善炉子供热制度、用氧与压缩空气强化冶炼的方法以及保证炉子及其设备的定期检修和炉子检修质量与热工工作的逐工序检查都非常重视,从而缩短了熔化期和精炼期。炉子和设备的现代化该厂单上升道平炉采用废钢-矿石法炼钢,铁水配比为55～58％,固体氧化剂耗量为20～40公斤/吨钢。在炉子改造过程中,考虑了炉子热工和冶炼工艺的主要特点以及车间与全厂的发展前景(包括生态学问题)。
In the process of trying to improve the production capacity and service life of open hearth furnace, Tajil Iron & Steel Co., Ltd. improved the furnace structure and equipment by using mechanized means to improve the stove repair system and raised the reasonable reuse of refractory materials and refractory materials produced by the factory, Improve the stove heating system, with oxygen and compressed air to strengthen the smelting method and to ensure that the stove and its equipment, regular maintenance and repair of stoves and thermal work by the work-by-process inspection are very important, thus shortening the melting and refining period. Modernization of Stoves and Equipment The mill’s Ascending Road Hearth furnace uses scrap-ore ores with 55 to 58% of hot metal and 20 to 40 kg of solid oxidizer. In the furnace reform process, the main features of the furnace thermal and smelting processes as well as the development prospects of the workshop and the whole plant (including ecological issues) are considered.
