为了年休定检,本钢6号2850m3高炉进行了50h的休复风操作。休风前进行了加净焦、轻负荷,降低配料碱度并适当提高炉温等准备工作,确保炉况稳定顺行,炉缸工作状态活跃。休风后按计划有序进行检修,确保在规定时间内安全完成检修工作。复风后,采用堵部分风口操作,通过合理控制风量、风温、喷煤、富氧及出铁等关键环节,实现了复风后快速恢复。
In order to determine the off-year inspection, Benxi Iron and Steel 6 # 2850m3 blast furnace 50h off the wind operation. Rest before the wind plus net coke, light load, reduce the alkalinity of ingredients and appropriate to improve the furnace temperature and other preparatory work to ensure stable and steady furnace conditions, hearth active state of work. After the break, arrange the maintenance according to the plan in an orderly way to ensure the overhaul work is completed safely within the stipulated time. After the re-wind, the use of blocking part of the outlet operation, through the reasonable control of air volume, air temperature, coal injection, oxygen enrichment and iron and other key areas to achieve a complex recovery after the wind quickly.
