为生产钢锭、铸件或电炉用的半成品,采用纯氧或富氧空气吹炼生铁的方法正愈来愈广泛地应用着。近来,有建议要改进转炉各部件的结构。从侧面经转炉炉口引入喷嘴用的设备,见图1;大家知道,把喷嘴垂直引入是很不方便的。喷嘴 a 固定在小车б上,小车沿轨道в移动。氧气和冷却喷嘴所用的水经软管г供给。其次,在平面图中建议设置斜向导向墙时,可扩大炉口附近的火焰空间(导向墙位于转炉炉口与烟
The method of blowing pig iron with pure oxygen or oxygen-enriched air is being used more and more widely for the production of semi-finished products for ingots, castings or electric furnaces. Recently, it has been proposed to improve the structure of converter components. From the side through the mouth of the converter into the nozzle equipment used, see Figure 1; As we all know, the vertical nozzle is very inconvenient. The nozzle a is fixed on the car б, the car moves along the rail в. The water used for oxygen and cooling nozzles is supplied via hose г. Secondly, it is recommended to set the inclined guide wall in the plan view to enlarge the flame space near the mouth of the furnace (the guide wall is located between the converter mouth and the smoke
