Conclusions
At the continuous-casting line at NLMW we have tested pouring with a protected stream of metal from the steel-pouring ladle with the aid of quartz and graphite-chamotte tubes. It was established that the optimum design of the protective device consists of a refractory tube 750 mm long in conjunction with a stationary tube fixed on the lid of the intermediate ladle. At the point of junction between the two tubes, inert gas is injected to give additional protection. The structure of the device for bringing the tube up to the ladle should ensure tight joining of the tube with the collector nozzle and mobility of the tube during pouring.
