Product parameters

Name: Magnesium iron spinel brick

Features: (1) During use, the hot surface of the brick forms a layer of calcium-iron or calcium-aluminum-iron-oxide with higher viscosity, which improves the performance of the kiln skin and the firmness of the kiln skin, which is suitable for protecting the lining The brick life cycle is extended.

(2) High spinel content, not only high strength but also excellent thermal shock resistance, but also can effectively resist the chemical attack of cement clinker liquid phase and alkali, sulfur and other gases.

(3) Spinel and periclase are inconsistent in thermal expansion during firing and cooling. The micro-cracks formed between the two can buffer the stress impact caused by temperature changes and avoid brittle bursting of lining bricks.

(4) Chromium-free and environmentally friendly.

Performance: 1. Excellent kiln-hanging performance

2. Low thermal conductivity (1000℃, 2.27w/m•k), low thermal expansion coefficient (1000℃, 1..217%);

3. It has excellent structural flexibility, and has strong anti-erosion and anti-permeability capabilities against K2SO4, Na2SO4, NaCl, and KCl alkali salts that are decomposed by cement materials.

4. The load softening temperature is high, and the thermal shock resistance is excellent. It is suitable for the key parts of SP and NSP kilns with high kiln temperature, fast speed, strong alkali corrosion ability and heavy mechanical load. It can effectively extend the life of the furnace lining and maintain a low Kiln shell temperature.
