Introduction of refractory magnesium iron spinel brick
The Magnesium iron spinel refractory brick is compounded with iron-aluminum spinel and adopts special production technology to ensure that Fe in the product exists in the form of Fe2+, so that the product has good adhesion to kiln skin, corrosion resistance and flexibility. Magnesium iron spinel refractory brick is an ideal chrome-free basic refractory material for cement rotary kiln firing zone.

Application site of refractory magnesium iron spinel brick
ZJMI Magnesium iron spinel refractory brick is suitable for all kinds of cement rotary kiln firing zone, transition zone and cooling zone. Selecting high-quality refractory materials, hanging the kiln skin, and using fuels that meet the requirements to slow down chemical erosion are the key factors to prolong the service life of the rotary kiln. ZJMI magnesia-iron spinel brick is your best choice.
Features of refractory magnesium iron spinel brick
Zhenjin Company was the first in China to develop a chrome-free and environmentally friendly magnesia-iron spinel brick. This product is based on magnesia and iron-aluminum spinel as the main materials, and by introducing active spinel into the matrix components, The product forms a network-like spinel structure during the sintering process. Our products are widely recognized in the cement industry.
