金属溶融炉
Document Type and Number:
Japanese Patent JP6778357
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a metal fusion furnace capable of preventing an inside refractory layer from deforming due to temperature difference, and capable of being prevented from damaged due to occurrence of a crack or the like.SOLUTION: A metal fusion furnace 1 has at least two layer of an outside heat insulation layer α comprising heat insulation material and an inside refractory layer β comprising refractory material formed inside the outside heat insulation layer α, and can hold a predetermined capacity of molten metal. The inside refractory material layer β is formed by assembling a plurality of pre-molded molding members β1-β5. Between the inside refractory layer β and the outside heat insulation material α, formed is an outside refractory layer γ comprising material having high compression strength.SELECTED DRAWING: Figure 2
