国外一些转炉钢厂为提高转炉的炉体寿命,采用了一种对炉体进行吹风冷却的技术。它是通过设置于转炉炉腹钢板和耳轴托圈之间的风冷装置,向炉体喷吹空气使之冷却。采用风冷技术后,可使转炉炉壳钢板的温度降低约300℃,从而可显著提高炉龄。日本神户钢铁公司加古川钢铁厂为提高该厂250t复吹转炉的炉龄,对炉体采取了吹风冷却的措施。它采用由多个喷嘴构成的空气喷吹装置对炉体喷吹空气使之冷却。通过合理地选择喷嘴的直径、喷嘴的间距和壁厚,可将喷嘴喷出的空气量的波动控制在3％上下。加古川钢铁厂所采用的风冷装置的喷嘴直
Some foreign converter steel mills in order to improve the life of the converter furnace, using a furnace for hair cooling technology. It is through the air placed in the converter between the belly plate and trunnion ring air-cooled device, blowing air to the furnace to make it cool. The use of air-cooled technology, the furnace shell steel can reduce the temperature of about 300 ℃, which can significantly improve furnace age. Kakogawa Steel Works, Kobe Steel Company, Japan In order to increase the furnace life of the 250t BOF converter, the furnace has taken measures to cool the furnace. It uses a plurality of nozzles consisting of air blowing device for blowing air to the furnace to make it cool. By reasonably selecting the diameter of the nozzle, the nozzle pitch and the wall thickness, the fluctuation of the amount of air ejected from the nozzle can be controlled at about 3%. Kakogawa steel plant used by the air-cooled device nozzle straight
