Magnesia Brick
Magnesia brick is a high temperature refractory material with good thermal shock resistance, ductility and thermal stability. It has high-temperature refractory performance, the service temperature can reach above 1000 ℃, and its refractory temperature can reach 1700 ℃, and its refractoriness is stronger than aluminum brick.
1. Good thermal shock resistance
2. Strong resistance to temperature changes
3.Good thermal conductivity
4.Good corrosion resistance
5.light weight
Magnesia Brick Description
Magnesia brick has the characteristics of strong refractory performance, low heat absorption and thermal conductivity, long service life, non-combustibility, etc., and its weight is light, with a specific gravity of only 2.2 to 3.3, easy to process and install, and lighter than clay bricks and asbestos bricks. The body installation cost is low, so magnesia bricks can replace clay bricks, and are used in the insulation layer of refractory furnace bodies such as sintering furnaces, casting furnaces, and hot blast stoves, as well as insulation protection under other high-temperature conditions.
The Application Of Magnesia Brick
Magnesia bricks have good high temperature resistance, corrosion resistance, high thermal elasticity, easy installation and maintenance, etc., which can increase the speed of the melting process, ensure the safety of the furnace, and maintain the normal operation of the alloy furnace.
Magnesia bricks can be used for the furnace bottom, furnace wall, furnace nozzle, etc. of non-ferrous metal smelting furnaces, which can avoid damage to the furnace wall due to thermal expansion and contraction and burn out of the nozzle due to uneven heating during the non-ferrous metal smelting process
Magnesia brick is a refractory material with good thermal stability. It can be used as a lining in the electric arc furnace to resist the thermal shock of the electric arc furnace; its good refractory performance can effectively prevent heat loss and make the operation of the electric arc furnace more stable. reliable
Magnesia bricks are widely used in the glass kiln as protective bricks, lining bricks, foot bricks, etc. It has good fire resistance and excellent heat insulation performance, can effectively reduce the temperature in the kiln, improve the quality of glass products, and can prevent dehydration and melting in the glass melting pool.
The application of magnesia bricks in lime kiln is to prevent the flame and heat from escaping in the kiln. Due to the excellent refractory performance of magnesia bricks, it can resist high temperature and keep the flame and heat in the kiln within a certain temperature range, so that the melting effect is more ideal.
Magnesia brick is a commonly used heating furnace brick material, which can be used in various types of heating furnaces, including resistance heating furnaces, thermocouple heating furnaces, thermistor heating furnaces, thermoelectric heating furnaces, etc. Magnesia bricks can improve the thermal efficiency of the furnace.
