ABSTRACT:
A blasting device to be used to introduce a gas and/or a solid material into a metallurgical vessel such as a convertor includes a plurality of blasting tubes arranged in a tube bundle, with ends of the tubes being inserted into respective receiving bores formed in a metal apertured plate, with a press fit therebetween. A space defined within the tube bundle is filled with a prefabricated ceramic internal member. The tube bundle with the internal member therein are positioned within a pressing mold that is partially filled with a portion of ceramic material to be used to form a blasting brick. The remainder of the ceramic material to form the blasting brick then is filled into the interior of the pressing mold. The mold then is operated to press the ceramic material to form a blasting brick with the tube bundle and internal member situated therein.
