通过对堵塞水口及堵塞物形态的调查，分析了引起水口堵塞的主要原因，并采用了中间包塞棒吹氩技术来预防水口堵塞。工业实验表明，该技术不仅能有效地防止水口堵塞，增加低碳铝镇静钢的连浇炉数，而且还可改善钢质
Based on the investigation of the shape of the blockage and the blockage of the blockage, the main causes of the blockage of the blockage were analyzed. The tundish stopper argon blowing technique was adopted to prevent the blockage of the blockage. Industrial experiments show that this technology can not only effectively prevent the blockage of the outlet, increase the number of continuous casting furnace of low carbon aluminum killed steel, but also improve the quality of steel
