PROBLEM TO BE SOLVED: To obtain a refractory having a structure of lining material into which different components are not readily permeated standing even a high- temperature use and prolonging a useful life and a furnace lining material capable of safely and stably carrying out an operation. SOLUTION: In a refractory for lining an induction furnace useful for melting and refining a metal containing a rare-earth metal material and a rare-earth metal component and an alloy of the metal and an iron-based metal, the refractory comprises 3-15 wt.% of silicon carbide 55-97 wt.% of aluminous material and 0-30 wt.% of mullite in which the content of the two or the three is 90 wtr.% and the content of the three components of SiC, Al2O3 and SiO2 is >=85 wt.% and 0-20 wt.% of a sintering auxiliary to give the objective induction furnace comprising a lining material composed of a dry refractory. |
