一、概况滑动水口是利用两块紧密接触的带孔滑板砖的相对运动,并借助其它部件的配合,以达到控制钢流浇注的装置。炼钢工艺应用塞棒控制钢液浇注,在国内外沿袭已久。进入廿世纪,特别是在六十年代以后,由于炼钢耐火材料的不断发展,在国际上陆续试验应用了滑动水口浇注。在小为几吨大至三百吨以上的钢水 I. Overview Sliding nozzle is the use of two closely linked with the relative movement of perforated slide brick, and with the cooperation of other components, in order to achieve control pouring steel flow device. Application of steel stopper plug control liquid pouring steel, at home and abroad have been followed. Into the twentieth century, especially after the sixties, due to the continuous development of refractory steelmaking, the succession of the international pilot test sliding gate. In the small number of tons up to 300 tons of molten steel
