Definitions

  • a weir arrangement that can be retro-fitted to an existing furnace to provide for increased capacity/throughput.
  • This can provide a scalable solution in which a furnace using a taphole(s) for the batch tapping of molten materials could be retro-fitted with a weir for increased throughput and more stable operability.
  • the weir cooling panel 132 comprises a block of material, having a planar furnace attachment side 132A and a curved weir abutment side 132B (see for example Figure 3 ) configured to form a curved inner surface of the weir against which refractories 144 can be laid.
  • the weir cooling panel 132 is typically formed from copper or another heat conductive metal configured to cool a selected area proximate the cooling panel 132 of and around the molten material connection 110A and 110B between the weir module 100 and the furnace 10.
  • the cooling panel 132 can be cooled by various means. In the illustrated embodiment, cooling fluid such as water is used to cool the panel 132 using a series of cooling conduits extending through the panel 132. Cooling of this region ensures a protective coating of slag and metal form over the refractories, reducing refractory wear in this area from the flow of molten material through and around the molten material passages 110A and 110B.
  • Each weir module 100 is constructed as a discrete structure/ module which can be individually attached or detached from the cooperating weir attachment section 120 of the furnace 10.
  • the illustrated weir module 100 comprises a generally cylindrical steel shell 141 defining a base 136, sides 138 and roof structure 140.
  • the weir cooling panel 132 forms one part of the structural rear side 142 of the weir module 100.
  • a refractory lining 144 is laid within that structure to contain the molten material which flows from the metal bath 14 within the furnace 10.
  • a copper tapping block or valve 148 is included in the front side 138A of the weir module 100 to enable removal of molten material from inside the weir module 100.
