1.缩短高炉休风倒流时间高炉工作中一旦遇到风口设备发生故障时必须临时急休风加以处理。此时为减少风口区域散发的煤气和热量,以确保操作人员的安全和缩短处理时间,通常需采取倒流方式。即利用倒流休风设施,将风口区的烟气从热风围管经倒流休风阀排到大气中。宝钢1号高炉在处理上述情况时。日方 1. Shorten the blast furnace wind back time Blast furnace work once encountered in the event of equipment failure must be a temporary emergency off to be addressed. At this time to reduce gas and heat distribution tuyere area to ensure operator safety and reduce processing time, usually need to take the reverse flow. That the use of wind breaks off the wind facilities, the tuyere area flue gas from the hot air around the pipe to the atmosphere through the return valve. Baosteel No. 1 blast furnace in dealing with the above situation. Japanese side
