The difference between aluminum brick and magnesia brick

The difference between aluminum brick and magnesia brick

1. Refractoriness, the refractoriness of high-alumina refractory bricks is above 1770℃, while the refractoriness of magnesia bricks is as high as 2000℃.

2. Load softening degree, 48%-80% load softness of high aluminum products is generally 1420-1550, magnesia brick refractoriness is 1520~1600℃, and the load softening starting temperature of high-purity magnesia products can reach 1800℃.

3. The price. The price of high-aluminum products is 1,000 to more than one ton per ton, and the price of magnesia bricks is between several thousand and more than 10,000 per ton.

4. Different parts of use and different chemical properties. High-aluminum refractory products are neutral, suitable for ironmaking blast furnaces, coke ovens, hot blast furnaces, converters, glass kilns, cement rotary kilns and other industrial kilns. Magnesium bricks are alkaline and are used in steelmaking furnace linings, ferroalloy furnaces, iron mixers, non-ferrous metallurgical furnaces, lime kilns for building materials, regenerator grids and heat exchangers in the glass industry, and high-temperature calcinations in the refractory industry. Kiln and tunnel kiln, etc.
