ABSTRACT:
A taphole assembly comprises three refractory pieces: (1) a monolithic central block with a hole for the passage of molten metal and (2) upper and lower wedge supports for the central block. The purpose of the assembly is to position the taphole between parallel layers of lining brick with the metal conducting hole at an angle to the lining brick surfaces. The assembly is installed by supporting the central block on a counterweighted bar in position in the furnace, and constructing the furnace lining around the assembly.
