ABSTRACT:
An air cooled ceramic stopper valve and actuating rod for a bottom pouring ladle. Ceramic parts are assembled onto a metallic stopper rod which contains an enlarged head portion. The metallic stopper rod head is notched, so that refractory cement used to bond the ceramic parts forms a strong mechanical bond between the metal rod and the ceramic point of the valve. The notches provide enough strength in the joint between metal rod to ceramic point to permit shearing loose a frozen stopper valve by rotation (when the valve head [point] bonds to the ceramic orifice).
