Molten re-grit magnesia chrome brick for electric arc furnace

The furnace body of the electric arc steelmaking furnace is composed of a furnace cover, a furnace door, a steel discharge tank and a furnace body, and an alkali refractory material is used for the furnace bottom and the furnace wall.

Magnesia sand and chrome ore are used as basic refractory materials, which are produced by melting in an electric arc furnace, pouring molding, heat preservation, slow cooling, and cutting.

The molten re-glued magnesia chrome brick is made of sintered magnesia and refractory grade chrome ore. The space between the refractory particles is combined with the silicate. The refractory material of the magnesia chrome brick is greater than 2000 ° C, and the refractory material is above 1550 ° C. Stable volume at high temperatures, sudden cooling, sudden performance. Heat is better than magnesium brick. The electric arc furnace refractory magnesia chrome brick has good thermal shock resistance and has the characteristics of high temperature resistance, corrosion resistance, thermal shock resistance and volume stability under high temperature.

Molten re-adhesive magnesia chrome bricks are mainly used in metallurgy (open hearth furnaces, electric arc furnaces), non-ferrous metals (metallurgical furnaces), construction and materials (cement rotary kiln, glass kiln).
