きる効果がある。According to the present invention, since the inner tank (furnace body) is formed by integral molding of ceramics, there is no so-called seam, and there is no possibility that the fire resistance caused by the seam is reduced. In molding , the gap between the outer mold and the core is filled with the ceramic water kneaded material and solidified, so that there is an effect that a large amount of homogeneous products can be produced without requiring skill. In addition, since the heat-insulating plate is attached via the separation layer, there are various effects such that there is no possibility that the outer layer is adversely affected by thermal expansion of the furnace body (inner tank). Also, a molten metal tank manufactured according to the present invention.
Because the separation layer is, replacement of the inner tub is in very easily
There is a clear effect .
