High Erosion Resistance Fire Resistance Magnesia Alumina Spinel Brick For Cement Rotary Kiln
The magnesia-alumina spinel brick is sintered at a high temperature above 1700°C in an ultra-high temperature tunnel kiln, with high bulk density, high mineral phase content, well-developed grains, uniform structure and stable quality.Magnesium aluminum spinel has good corrosion resistance, strong corrosion and peeling ability, good slag resistance, abrasion resistance, good thermal shock stability, and high temperature resistance. It is an ideal material for producing magnesia-alumina spinel bricks, ladle lining bricks, ladle castables and other refractory products for high temperature zone of cement rotary kiln. Magnesium-aluminum spinel is widely used in refractory materials, iron and steel smelting, cement rotary kilns and glass industrial kilns.
Magnesite Bricks Feature
1.High refractoriness,usually the refractoriness is above 2000°C.
2.Refractoriness under load about 1500-1550°C because of poor high-temperature intensity.
3.Strong ability to resist basic (alkaline) slag,can not contact with acid refractory material.
4.Hydrability, keep product away from moisture during storage.
