MK is made of magnesia and chromite and processed by high-temperature sintering. MK is the most extensively used in the world. They are used in the burning zone and transition zone of cement kilns. They are adaptive to any conditions and are economical with properties of good clinker coating, sound thermal shock resistance, good heat load weariness resistance, good chemical corrosion resistance, good thermal fatigue resistance, and good oxidation-reduction resistance. The disadvantage of it is hazardous to the environment. Therefore MAGSCIE developed magnesia chrome bricks of low chrome or chrome-free as alternatives to traditional MK products.

Properties of Magnesia Chrome Brick:

• Excellent clinker coating;
• Good thermal shock resistance;
• Excellent thermal load fatigue resistance;
• Strong chemical resistance and oxidation resistance.

Applications and Advantages:

• These bricks are primarily used in the burning zone and transition zone of cement kilns.
• They adapt well to various conditions and are economical. Additionally, they help in enhancing the performance of the kiln skin and prolonging the lining life in cement kilns.
