| Abstract: | 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, |
