Abstract
A lining for a bottom of a metallurgical vessel, comprising an impact pad having a plurality of close-packed, pre-formed, high-temperature, high-density refractory bricks, the pad having an upper impact surface, and a monolithic slab of a high-temperature refractory material encasing the pad, the slab encasing the pad wherein the upper surface of the impact pad is exposed.
Claims6
A lining for a bottom of a metallurgical vessel, comprising:
- an impact pad comprised of a plurality of close-packed, pre-formed, high-temperature, high-density refractory bricks, wherein said bricks are joined together by a metallic band, said pad having an upper impact surface;
- and
- a monolithic slab of a high-temperature cast refractory material encasing said pad, said slab encasing said pad wherein said upper surface of said impact pad is exposed.
A lining in a metallurgical vessel for receiving and dispensing a molten metal, comprised of:
- an impact pad comprised of a plurality of close-packed, pre-formed refractory brick wherein said plurality of refractory brick is bonded together by a mechanical fastener, said pad having an upper impact surface;
- and
- a monolithic slab of a high-temperature, cast refractory material encasing said pad, said slab encasing said pad wherein said upper surface of said impact pad is exposed.
In a metallurgical vessel for receiving and dispensing a molten metal, a refractory component comprised of:
- an impact pad comprised of a plurality of close-packed, pre-formed refractory brick, said pad having an upper impact surface;
- and
- a monolithic slab of a high-temperature, cast refractory material encasing said pad, said slab dimensioned to form a refractory lining over the bottom of a metallurgical vessel and said lining including lifting elements formed in said lining for facilitating movement of said lining.
A pre-formed impact pad comprised of:
- a plurality of high-density, high-temperature refractory bricks bonded together into a predetermined shape by a bonding composition, said bonding composition comprised of about 60% to 85% by weight of refractory fines having a particle size of less than 100 Tyler mesh (150 μm), and about 15% to 40% by weight of a polymeric resin;
- and
- a plurality of projections extending outwardly from the sides thereof, wherein said projections are metal clips attached to said impact pad.
