据法国文献报道,法国的勒罗埃氏和西蒙氏(P.LeroyR.Simon 见文献1及2)试验成功一种新的生铁脱矽方法,即在高炉出铁槽内喷入氧进行铁水脱矽。二氏采用的喷气槽构造如图1。这种构造的优点,在于氧是以分解得很细的状态自下向上喷入槽中的铁水流内,以使氧气和铁水在很短的接触时间内仍有充分的接触机会。槽底用型砖依次砌成,砖由带孔隙的耐火水泥制成。砖的两边采用致密的水泥镶成槽状.氧气管道由下端进入型砖,
According to the French literature, the French Le Loeger and Simon (P.LeroyR.Simon See References 1 and 2) successfully tested a new method of pig iron desiliconization, that is blast furnace iron injection tank oxygen ladle Silicon. II’s jet slot structure shown in Figure 1. The advantage of this configuration is that the oxygen is sprayed into the stream of molten iron in the tank in a very finely decomposed state so that there is still sufficient contact between the oxygen and the hot metal for a short contact time. The bottom of the tank brick with brick, brick made of refractory cement with pores. Bricks on both sides of dense cement inlaid groove.Oxygen pipeline from the bottom into the brick,
