ABSTRACT:
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.
