Latest Patents
Noriji Numata holds a patent for a metal-impregnated refractory product. This invention boasts high resistance to slag attack, gas attack, and spalling, making it suitable for various types of molten metal treatment vessels. The product is created by forming a material of refractory particles, primarily consisting of MgO or Al₂O₃, which is then heated to obtain a porous material body containing at least 4 vol % of open pores. A metal or alloy, mainly composed of iron, chromium, or nickel, is impregnated into the porous body at a ratio of 25 vol % or more of the open pores. This innovative design allows the metal to fill the pores from the surface to a predetermined depth, enabling the refractory product to withstand high-temperature damages and ensuring stable long-term use.
