摘要: A pressurized tundish for controlling a continous flow of molten metal characterized by having a pair of principal compartments, one being essentially unpressurized and receiving molten metal introduced thereto, and the other being adapted for maintaining a controlled gaseous pressure over the surface of the fluid metal therein, whereby, by controlling the pressure within the pressurized chamber, metal exiting from the tundish is made to flow continually and at a controlled rate.

摘要: Apparatus for introducing reactive and nonreactive gases through the refractory lining of a metallurgical vessel, such as bottom injection of such gases into a BOF to improve mixed blowing efficiency. The apparatus comprises one or more refractory blocks which may be set within a metal canister. The refractory blocks have a plurality of slots each containing one or more small diameter nonreactive metal tubes for conveying gases. The refractory block may also contain means for measuring the rate of wear of the refractory blocks in the canister.
