Introduction to the use of magnesium bricks

 
The linear expansion rate of magnesium brick under 1000 ～ 1600 is generally 1.0% ～ 2.0%, and it is approximately or linear. In refractory products, the thermal conductivity of magnesium brick is second only to carbon brick, which decreases with the increase of temperature. . Under 1100 water-cooled conditions, the number of thermal shocks of magnesia bricks is only 1-2. Magnesia bricks have strong resistance to CaO and ferric slag, but weak resistance to acidic slag containing SiO2. Therefore, it cannot be in direct contact with silicon bricks during use. Generally, it should be separated by neutral bricks. At room temperature, the conductivity of magnesium bricks is very low, but at high temperatures, its conductivity cannot be ignored. The performance of magnesia bricks varies greatly depending on the raw materials used, production equipment, and technological measures.
 
Magnesium bricks are widely used in steelmaking furnace linings, ferroalloy furnaces, mixed iron furnaces, non-ferrous metallurgical industrial furnaces, lime kilns for building materials, and grids for glass industrial heat storage cells due to their high temperature performance and strong alkali slag resistance. Heat exchanger, refractory industry high temperature calcining kiln and tunnel kiln, etc.
