摘要
以承钢一作业区高炉生产实践为研究对象,通过加强入炉原燃料的管理、上部装料制度与下部送风制度相结合、优化热制度、造渣制度、炉前出渣出铁制度等措施,达到了高炉煤气流稳定、操作炉型合理的目的。坚持"低硅钛"冶炼的技术方针,铁水中的[Si+Ti]控制为(0.4±0.1)%,铁水温度为(1 470±15)℃,在保证炉缸热量充足的同时,有效地缓解炉渣黏稠的问题,实现了高炉钒钛矿强化冶炼,经济技术指标不断提高。
With blast furnace production of Work Area 1 of Chengsteel as research object, some measures are adopted and the target is reached of gas flow steady and operation profile reasonable： strengthening management of raw and fuel materials coming into the furnace, combining upper charge system and lower blowing system, optimizing thermal system, slag - forming system, deslaging and casting system and etc. In production we persist in the technical guide line of ＂ low silicon - titanium＂ smelting, [ Si ＋ Ti ] is controlled at （0.4 ± 0.1 ） % , hot metal temperature at （ 1 470± 15） ℃. That guarantees full heat quantity for hearth, at the same time effectively relieves slag sticky, realizes blast furnace vanadium - titanium ore strengthening smelting, makes economic and technical indexes continuously raised.
