Product Description

Corrosion resistance magnesia alumina spinel refractory bricks for rotary kiln

Product Description

Magnesia Alumina Spinel Brick Introduction

Magnesia alumina spinel brick is made of high-purity magnesia and pre-synthetic magnesium-aluminum spinel as the main raw materials, which are sintered at high temperature above 1800 °C in an ultra-high temperature tunnel kiln. It is characterized by high temperature resistance, high strength, erosion resistance, corrosion resistance, spalling resistance, good slag resistance, good thermal shock resistance, etc.,

Magnesia Alumina Spinel Brick Features

1. Excellent stickability to kiln coating performance;
2. Low thermal conductivity and small thermal expansion coefficient;
3. It has excellent structural flexibility, and has strong erosion resistance and penetration resistance to K2SO4, Na2SO4, NaCl and KCl alkali salts decomposed by cement materials.
4. High load softening temperature and excellent thermal shock resistance, suitable for key parts of SP and NSP kilns with high kiln temperature, fast speed, strong alkali erosion ability and heavy mechanical load, which can effectively extend the life of the furnace lining and maintain a low temperature of the kiln barrel.
5. Good anti-peeling performance:Magnesium aluminum spinel brick is better than the direct combination magnesia-chrome brick at anti-peeling performance. The life of the cooling zone and the transition zone of the kiln can be directly combined with magnesia-chrome brick.

Product Application

Magnesia Alumina Spinel Brick Applications

Magnesia alumina spinel bricks are widely used in refractory materials, steel smelting, cement rotary kilns, and glass industry furnaces. They are ideal refractory products for high-temperature zones of cement rotary kilns, ladle lining bricks, and production of ladle castables.

Packaging & Shipping

Wooden pallets with plastic film or according to your request.

1. Strong packing protects the goods from any possible damage during transit.
2. Solid packing and overall stuffing prevent the cases from vibration and jarring.
3. Necessary precaution is taken to protect goods from pilferage or rain.
