摘　　要：为完成280万t年产量目标,河钢邯钢围绕“单浇次连拉炉数提升”展开了攻关,重点在于耐材浸入式水口的研究。按照浸入式水口渣线部位残厚不能低于7 mm的要求,通过延长浸入式水口的下降时间,减少下降长度,增加有效渣线长度等措施,平均残厚增加到10.57 mm,同时平均连拉炉数达到22.34炉,较之前提高1.9炉,甚至有十几个浇次达到32炉,连拉炉数显著提升。In order to achieve the annual output target of 2.8 million tons,HBIS Hansteel has carried out key research around"increasing the number of continuous drawing furnaces for single pouring",focusing on the research of submerged nozzle.By extending the descent time of the submerged nozzle,reducing the descent length,making the residual thickness of the slag line of the submerged nozzle not less than 7 mm and increasing the effective slag line length,the average residual thickness was increased to 10.57 mm.At the same time,the average number of continuous drawing furnaces reached 22.34,1.9 furnaces higher than before,and even more than a dozen pouring times reached 32 furnaces,which significantly increased the number of continuous drawing furnaces.
