冲天爐在熔化过程中,如果采用打开渣孔的操作方法,可以提高鉄水的温度。根据北京很多工厂采用后的效果証明,在使用含灰分25％左右的土焦的情况下,鉄水温度經常保持在1380～1400℃,有时还达到1420℃。采用开渣操作不需要增添任何設备和人力,只要从开爐到拉爐一直将渣孔打开,选择合适的前爐渣孔和过桥尺寸,控制适当的风压和风量,就能立竿見影,提高鉄水温度,因此在国內已經引起广泛的重视。
Cupola in the melting process, if you open the slag hole operation method, you can increase the temperature of the water. According to the results of many factories in Beijing, it is proved that the water temperature is always maintained at 1,380 to 1,400 ° C, and sometimes up to 1,420 ° C, even with the use of a soil coke containing about 25% ash. Adopting drossing operation does not need any additional equipment and manpower, as long as the slag hole is opened from the furnace to the draw furnace, the appropriate front slag hole and the bridge size are selected, the appropriate air pressure and air volume are controlled, the immediate and improved鉄 water temperature, it has attracted widespread attention in China.
