针对中间包包衬耐材的不定形化 ,对中间包包衬浇注施工设备与包衬耐材、结构的改进进行了探讨。实用结果表明 ,通过上述改进 ,包衬寿命显著增长 ,耐材成本明显降低 ,施工周期缩短 ,人员减少。图 5表 5。中间包耐材的不定形化与改进寿命的提高@陈留根 Aiming at the indefiniteness of lining refractory material of tundish, the construction equipment of casting lining lining and lining refractory material were improved. The practical results show that through the above improvement, the lining life is significantly increased, the refractory material cost is obviously reduced, the construction period is shortened and the number of personnel is reduced.
