Introduction of Magnesium Alumina Spinel Fire Brick

Magnesium Alumina Spinel Fire Brick is a high-grade basic refractory material with periclase and spinel as the main minerals, which is formed by high pressure molding and high temperature sintering, and at the same time adding a specific mineralizer to improve the internal structure of the product. The service life of Magnesium-aluminum spinel brick in the new dry process cement kiln of 5000T/D cement clinker can reach more than 12 months

Why Choose Us ?

1,The magnesia-aluminum spinel bricks developed by Zhengzhou Zhenjin Refractory Co., Ltd. for large-scale cement kilns, through the optimal selection of raw materials, reduce the SiO2 and Fe2O3 that affect the product stability to a reasonable range, and improve the spinel bricks. Erosion resistance. At the same time, the strength of the product at high temperature is improved.

2,By introducing alumina-based spinel, the magnesia-alumina spinel brick is formed in-situ spinel during high-temperature sintering, and the micro-cracks generated during the reaction process are used to improve the thermal shock stability of the product. The adjustment of matrix and particles solves the problem of low softening temperature under load.

3,The strength and anti-wear properties of magnesia-alumina spinel bricks are improved by adjusting the critical particle size and particle gradation and using high-tonnage brick press and ultra-high temperature sintering technology, which solves the problem of spinel bricks and cement at high temperature. Structural spalling from clinker infiltration deterioration. The service life of magnesia-alumina spinel bricks in the new dry process cement kiln of 5000T/D cement clinker can reach more than 12 months.
