Resin bonded carbon magnetite brick because of its good thermal shock resistance and slag resistance of iron and steel industry, in particular applied basic oxygen furnace and electric arc furnace. Carbon has excellent performance such as high thermal conductivity, low thermal expansion coefficient, high heat shock stability, at the same time and wettability of the job of slag has good corrosion resistance and anti erosion ability. As is known to all, the brick body carbon easy oxidation, which restrict its use in high temperature, the oxidation of carbon from the beginning of the 300 DEG C, with the increase of temperature oxidation speed.
Ceramic materials (SiC, carbon silicon oxide) do coating in the flake graphite or carbon fiber, were impregnated with phosphate, cement foam board price and the use of surface glaze etc. These expensive methods used in the refractory brick have certain limitations, another method is through the steam treatment of fine particle boron, TiB2, ZrB2 and SiC and other materials to do thermal barrier coating on graphite or carbon composite material.
