据1990.No3 P33报道西伯利亚第二转炉车间钢水惰性气体(氩气或氮气)是在位于钢水罐车移动的轨道上方的两个三枪台架上进行(见图)。喷枪带有—8牌号的袖砖外套。喷枪头是两缝式的,这样能增加惰性气体流量,从而加大喷吹压力(P=0.4～0.9MPa)。为了减少当枪头烧损时从钢水罐内喷溅的的几率,在距喷口截面500～600毫米处,安装了缩孔板,其通道截面比喷枪头处大些。
According to 1990. No.3 P33 Steel inert gas (argon or nitrogen) from the second converter plant in Siberia was carried out on two three-gun stands located above the track on which the tankers were moving (see figure). Spray gun with -8 grade sleeve jacket. Spray gun head is two slit, so can increase the inert gas flow, thereby increasing the injection pressure (P = 0.4 ~ 0.9MPa). In order to reduce the probability of splashing from the tank when the tip is burnt, a shrink plate is installed at a distance of 500-600 mm from the outlet section, with a larger cross-section than the head of the spray gun.
