Description
Introduction of refractory magnesium ferrum spinel brick
Refractory magnesium ferrum spinel brick is a new generation of chromium-free basic refractory products for cement kilns. It uses high-purity magnesia and capacitor iron-aluminum spinel as the main raw materials, and uses MgO, Fe2O3, Al2O3 spinel and periclase as the main crystals. Mutually. Adding specific mineralizers, it is formed by high pressure molding and high temperature sintering. Refractory magnesium ferrum spinel brick is a green and environmentally friendly material with high technical content.
The addition of iron-aluminum spinel to the magnesia-iron spinel brick solves the problem that chrome-free basic bricks are difficult to stick to the kiln skin. The magnesia-iron spinel brick is easier to stick to the kiln skin than directly combined with magnesia-chrome bricks. The effect is also better and more stable. The refractory magnesium ferrum spinel brick effectively solves the problem of environmental pollution caused by the production of hexavalent chromium in cement kilns.

Advantage of Refractory magnesium ferrum spinel brick
1. During the use of Refractory magnesium ferrum spinel bricks, a layer of calcium iron or calcium-aluminum-iron oxides with high viscosity will be formed on the brick surface, thereby improving the performance of the hanging kiln skin, protecting the kiln lining and prolonging the life of the cement kiln. .
2. The capacitor iron-aluminum spinel synthetic material is added to the product, which not only has high strength but also has excellent thermal shock resistance, and can effectively resist the chemical erosion of the liquid phase of cement clinker and alkali, sulfur and other gases.
3. Spinel and cristobalite in Refractory magnesium ferrum spinel bricks are inconsistent in expansion during firing and cooling, and the micro-cracks formed between them can buffer the stress impact caused by temperature changes and avoid brick damage. Brittle burst.

Application scenarios of Refractory magnesium ferrum spinel brick
Refractory magnesium ferrum spinel 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.
