Description

Magnesia iron spinel bricks is a type of new product developed by ourselves independently by the conclusion of years’ working experience and combining the advanced technology of related large scale cement kilns at home and abroad. Which has already obtained the national invention patent. Magnesia ferrite spinel brick was successfully developed in the year of 2005, which has already been widely used in the firing zone of 5000d/t cement kilns at home and abroad and warmly. Warmly welcomed by the customers.

Magnesia-iron spinel bricks use high-purity magnesia sand and Al-Fe spinel sand as the main raw materials through reasonable proportioning, high-pressure molding, strictly control over the firing temperature and firing atmosphere to make the products have good flexibility and thermal shock stability, and no hexavalent chromium pollution for cement kiln burning zone.

  Technical Data:

  Application:

Magnesium-iron spinel bricks have the advantages of chromium-free environmental protection, good thermal shock stability, good "kiln skin" ability, good corrosion resistance, low thermal expansion and low thermal conductivity, and good structural flexibility. In practical applications, the service life of the brick is more than 1 year, the kiln skin is hung quickly in the firing zone, the thickness of the kiln skin is uniform and stable, the refractory bricks have no large pieces of collapse, and there is no spalling of the refractory bricks when the kiln is stopped, and the temperature of the kiln cylinder is low. Less heat loss
