Magnesia brick thermal stability and strong points in China

Magnesia carbon brick series used for the electric furnace are made by adoption of fused magnetite, high-purity magnesium sand and graphite as principal raw material, through high-pressure molding and low-temperature treatment. This product is mainly used for electric furnace lining, which enjoys advantages including high temperature resistance strength, corrosion and spalling resistance. According to the smelting conditions and the kind of smelting steel, different brands magnesia carbon bricks are available. Magnesia-carbon bricks are resin bonded bricks containing high-purity fused and or sintered magnesia and flake graphite as their main ingredients.

Advantages of fired magnesia chrome bricks:
Chrome ore and magnesia carbon brick magnesite-chrome brick mill Compact fitted after a total production of fine powder, coarse granule combined with brick and magnesite, are effective measures to eliminate loose effect. In this way made of magnesia-chrome brick, compared with ordinary magnesia-chrome brick, bricks of low porosity and compressive strength, refractories and bending strength are higher. With the chrome ore and magnesia carbon bricks properties powder compact, high temperatures, calcination of magnesite-chrome brick made of synthetic magnesia-chrome sand, slag resistance and high temperature strength than other magnesite-chrome brick good.

Poor thermal stability of mgo brick supplier:
Magnesia brick can only take water-2-3. Expanded the most magnesia bricks in refractory, low coefficient of linear expansion. So when the magnesia brick oven, you want to have plenty of expansion joints. dration of magnesia brick: magnesia brick prolonged under wet condition can slowly drate, magnesia brick strength greatly reduced, so you must pay firebrick refractory sale attention to moisture when stored magnesia brick.
