Molten metal furnace
A molten metal furnace capable of preventing or suppressing the molten metal leakage and controlling the leakage direction. A molten metal furnace including an outer wall in an outer peripheral portion and a molten metal storage part holding a molten metal, in which a plurality of lining material layers are arranged on an inner wall of the molten metal furnace forming the molten metal storage part; of the lining material layers, a first lining layer constituting a surface in contact with the molten metal is made of a refractory material; and a sealing material is provided on at least one boundary between the first lining layer and the outer wall.
1. A molten metal furnace comprising:
an outer wall in an outer peripheral portion; and
a plurality of lining material layers arranged on an inner surface of the outer wall to form a molten metal storage part holding molten metal,
wherein among the plurality of lining material layers, a first lining layer constituting a surface in contact with the molten metal is made of a refractory material, and
wherein a sealing material is provided on at least one boundary between the first lining layer and the outer wall, the sealing material comprising a sheet material obtained by interweaving fiber yarns comprising at least one of ceramic fibers and biosoluble ceramic fibers, and at least one of glass fibers and stainless steel fibers.
2. The molten metal furnace according to claim 1 ,
wherein the sealing material has a sheet shape with a thickness of 2 to 10 mm, and is provided in a single layer or a plurality of laminated layers.
3. The molten metal furnace according to claim 1 ,
wherein the at least one of glass fibers and stainless steel fibers comprise reinforcing fibers that are incorporated into the fiber yarns comprising strands of the at least one of ceramic fibers and biosoluble ceramic fibers.
