摘　　要：为提高中间包使用寿命,宣钢炼钢厂采用液压式连铸中间包快速更换定径水口技术,在3#R6m小方坯连铸机上11个中间包应用表明:在其它条件相同的情况下,平均单包连浇最少79.91炉,平均连浇最短22.38h,钢水收得率由97.61%提高到97.75%,吨钢成本降低2.07元。We apply the technique of fast hydraulic exchanging fixed-diameter nozzle for 11 tundishes of 3# R 6 m billet caster. It is showed that with same other conditions, in average a single tundish can cast at least 79. 91 heats, continuously cast for at least 22. 38 hours, and smelting steel＇s gathering ratio raised from 97.61 to 97,75 percent, the cost for per ton of steel reduces by 2.07 yuan,
