Magnesia-iron spinel bricks are mainly made of high-purity magnesia sand and alumina-iron spinel. We provide you with high quality magnesia iron spinel bricks and wholesale and sell magnesia iron spinel bricks at factory price.
Magnesia-iron spinel brick is a kind of refractory bricks made of spinel and special technology, mainly made of high purity magnesia sand and aluminum-iron spinel. Magnesia-iron spinel bricks have high purity, good thermal shock stability, high load softening temperature, good erosion resistance and excellent kiln skin hanging performance.
The main raw materials of magnesium-iron spinel refractory bricks are high-purity magnesium sand and aluminum-iron spinel, which are molded under high pressure, dried and fired at high temperature.
Excellent kiln-skinning performance
The magnesium-iron spinel bricks have excellent kiln skin hanging performance and kiln skin firmness, which is conducive to the protection of the lining bricks with a longer service life.
Good thermal shock stability
Magnesia iron spinel refractory bricks can withstand rapid cooling and heating at high temperatures, with excellent thermal shock stability.
Resistance to erosion
The magnesium-iron spinel brick can resist the erosion of many kinds of slag, and has good anti-erosion ability.
Magnesia iron spinel bricks are chrome-free and environmentally friendly, which can effectively solve the problem of environmental pollution caused by the generation of hexavalent chromium during the use of magnesia chromium bricks for cement kilns.
Magnesia iron spinel firebricks have excellent high temperature and corrosion resistance, and can be used for blast furnace body, waist, bottom, upper and lower furnace lining, as well as all kinds of steel ladle and iron ladle lining.
Magnesia iron spinel bricks have high temperature resistance and can resist the corrosive effect of cement dust and alkali steam, and can be used in cement rotary kiln kiln tail, kiln, kiln, kiln head seal and various kiln linings.
Non-ferrous metal metallurgy
Magnesia iron spinel firebrick bricks have excellent high temperature resistance and thermal shock resistance, and can be used in the construction of non-ferrous metal metallurgy used in the furnace and converter.
