摘要
安钢6号高炉在长期稳定顺行时,通过精心操作,可以在短期休风后快速恢复炉况,主要方法是:做好前期准备工作;休风时出净渣铁,逐步减风,适当控制水压、水量及顶温;复风时处理好料动、赶料线、恢复富氧喷煤及出铁操作。高炉曾经短期休风108min后,在33min之内恢复全风作业,而炉况稳定顺行。
Rapid re.blowing of Angang＇s No.6 BF condition after short term damping-down can be realized by aborative operation at the conditions d continuous stable smooth operation. The main methods are introduced as follows： doing anterior prepared work well; a few measures are adopted when short term blowing-down, such as acquiring the mollen slag and iron of computing the quantity from BF theoretietically, reducing the blast pressure gradually, controlling proper water pressure and quantity and furnace top temperature; a aeries of works are suitably carried out when reblowing, including handling BF burden move, achieving to fill ore and coke according to stockline, resumption of oxygen--onriebed pulverized coal-injection and tapping hot metal from taphole. No.6 blast furnace ever recovered the whole blast pressure operation within 32 minutes after blowing-down for 108 minutes, but a stabilizing smoothing of BF operation is ensured.
