HEAT INSULATOR FOR FUSION FURNACE, PRODUCTION METHOD OF HEAT INSULATOR FOR FUSION FURNACE, AND HEAT INSULATION METHOD OF FUSION FURNACE

摘要

PROBLEM TO BE SOLVED: To provide an easily handled technology capable of utilizing cut chips generated when cutting a ceramic-based siding material, effectively by being used for heat insulation of a fusion furnace without being buried.SOLUTION: A heat insulator 1 for a fusion furnace for suppressing heat dissipation from a molten metal surface so as to cover the molten metal surface by being inputted into the fusion furnace is formed by constituting granularly cut chips generated when cutting a ceramic-based siding material. Preferably, the cut chips are constituted of cut powder.
