ABSTRACT:
A metal-impregnated refractory product of this invention has high slag attack, gas attack, and spalling resistances and is used in various types of molten metal treatment vessels. A material of refractory particles mainly consisting of MgO or Al.sub.2 O.sub.3 is formed and heated by a suitable method to obtain a porous material body containing at least 4 vol % of open pores. A metal or an alloy mainly consisting of at least one type of a metal selected from the group consisting of iron, chromium, and nickel is impregnated in the porous material body at a ratio of 25 vol % or more of the open pores. The metal is filled in pores present in a region from the surface to at least a predetermined depth. The metal-impregnated refractory product can withstand various high-temperature damages and can be stably used over a long time period.
