中薄板坯连铸浸入式水口
摘要：
本实用新型涉及一种中薄板坯连铸浸入式水口，其特征是浸入式水口体的内腔为圆柱体；浸入式水口体的中部设有浸入式水口渣线，下部设有两个对称的正方体浸入式水口孔。浸入式水口孔(3)向下倾斜15°～25°。与现有技术相比，本实用新型的优点是：1.改进浸入式水口内腔形状，延长絮流后的使用时间；2.中薄板坯连铸中间包应用此类型浸入式水口后，在生产经过RH精炼处理后的钢水时，能够保证至少生产4罐不需要更换浸入式水口。
摘要（英）：

The utility model relates to a medium-thin slab casting immerged water gap which is characterized in that an inner cavity of the casting immerged water gap is a cylinder; the middle part of the casting immerged water gap is provided with an immerged water gap slag line and the lower part of the casting immerged water gap is provided with two cubic immerged water gap holes in symmetry. The immerged water gap hole (3) slants downwards in 15 degrees to 25 degrees. Compared with the existing technology, the utility model has the advantages of: 1. the inner cavity of the immerged water gap is improved and the service time after the wadding flowage is prolonged; 2. after the application of the immerged water gap in the middle bag of the medium-thin slab casting, at least four tanks of steel water after the RH refining treatment can be produced without the replacement of the immerged water gap.
