Abstract (en)
[origin: EP0679723A1] A blasting component for introducing gas and/or solids into metallurgical vessels is manufactured by:- a) inserting the blasting tubes as a bundle into bores machined in an apertured plate, the tubes having a press fit in the bores; b) fitting a prefabricated ceramic internal member within the tube bundle, the member surrounding each of the tubes; c) positioning the assembly in a pressing mould partially filled with the material to form a ceramic battery brick, then fully fill the mould and apply a pressing force to form the blasting brick with an internal tube bundle attached to an apertured plate. Also claimed is blasting device for introducing gas and solid material into a vessel formed as a blasting brick with an internal tube bundle, and formed using the method claimed above. <IMAGE>
