TAPHOLE ASSEMBLY FOR A MOLTEN METAL MANUFACTURING FURNACE AND METHOD OF FORMING THE SAME

摘要

An assembly (30) for forming a taphole in a molten metal furnace (14), the assembly (30) comprised of an elongated, isostatically pressed tubular member (40) formed of a refractory material. The tubular member (40) has a first end (42), a second end (44), an outer surface (46), and an inner bore (50) that extends from the first end (42) to the second end (44) and that defines a taphole to be formed. A block of refractory material (60) is attached to the tubular member (40) to form a base therefore. The block (60) engages in mating fashion the outer surface (46) of the tubular member (40) and has a planar surface dimensioned to rest upon a planar structural surface of the furnace (14) so as to support the tubular member (40) at a predetermined position and orientation relative to the furnace (14).
