Magnesium composite brick

Magnesium composite brick

Product introduction

Magnesium composite bricks are one of the traditional advantages of the company's production history for more than 50 years. According to the main raw materials, it is divided into three major categories. Magnesia-aluminum brick (MAB), magnesia-aluminum chrome brick (MAK), magnesium spinel brick (MAS).

Physical and chemical indicators

(1) Magnesia-aluminum brick (HYBRIMAG MAB)

Magnesia sand is used as the main raw material, and a small amount of high-alumina bauxite is added, which is formed by high-pressure molding and firing at medium temperature. It is an upgraded product of pure magnesium brick. Compared with the pure magnesium brick, it has higher load softening temperature, slag permeability resistance, thermal shock resistance and high temperature mechanical flexibility. It is widely used in the non-critical parts of the traditional metal smelting furnace (such as open hearth furnace, electric furnace, converter, non-ferrous metal smelting furnace, etc.) and the safety layer, as well as the small and medium glass furnace regenerator.

(2) Magnesium-aluminum spinel brick (HYBRIMAG MAS)

Magnesia (or corundum sand) and a small amount of synthetic spinel as the main raw materials, high pressure molding, high temperature firing. It is an upgraded product of pure magnesium brick and magnesium aluminum brick. Compared with the same matrix magnesium aluminum brick (or corundum brick), it has excellent high temperature load softening temperature and thermal shock resistance, so it is used in high temperature industrial furnaces to withstand strong thermal shock damage and to withstand high temperature and high temperature. Such as VOD ladle liquid line, free space and so on.

(3) Magnesia-aluminum chrome brick (HYBRIMAG MAK)

Magnesia sand, synthetic spinel and a small amount of chromite are used as the main raw materials, which are formed by high pressure molding and firing at medium and high temperatures. It is an upgraded product of pure magnesium brick and magnesium aluminum brick. Compared with the matrix magnesium aluminum brick, its load-softening temperature, thermal shock resistance and other performances are greatly improved. It is mainly used in the top position of kiln of various high temperature industrial furnaces, subjected to strong thermal shock damage parts, and long time high temperature load parts.
