Abstract
The present invention relates to a well brick or a tuyere brick for receiving a nozzle brick or a porous brick for injecting gas which is disposed on the bottom of a vessel for molten metal. A well brick is disposed on a bottom of a vessel for molten metal, and comprises a product formed into a shape of a cylinder or a frustum of cone by using an isostatic press. The well brick is made by mixing a raw material comprising aggregate of Al.sub.2 O.sub.3 as a main element, 0.3 to 10.0 weight % carbon material, 0.2 to 0.5 weight % metal or metallic powder of at least one element selected from the group consisting of Al, Mg, Ca and Si, and 0.1 to 30 weight % Mg and thermosetting resin as a binding material and by forming them.
