Products Description

As an important component of heat treatment equipment and refractory materials, magnesia bricks have the characteristics of good fire resistance, high strength, good heat resistance and stability, and low thermal expansion coefficient.

The main components of magnesia bricks are magnesium oxide, alumina, alkali metal oxides, rare earth oxides, etc. The hardness is between 4-6 and the density is 3-3.2 tons/cubic meter. The compressive strength is between 120-200 MPa, and the tensile strength is about 80 MPa. The refractory temperature is between 1500℃ and 2000℃, so it has good corrosion resistance and high temperature stability in harsh environments such as high temperature, heavy pressure and strong acid.

Precautions

1. Magnesia bricks should avoid heavy pressure and vibration during use to avoid breakage, shattering, etc.

2. Pay attention to the sealing and moisture during use of magnesia bricks. Excessive moisture will affect its performance and even its service life.

3. Damaged magnesia bricks should be replaced in time to avoid affecting the work quality and extending the service life.

4. Magnesia bricks should be moisture-proof and anti-collision during transportation and packaging to ensure their physical properties and density.

Products Advantages

Magnesia bricks have excellent heat resistance. Magnesia bricks are made of high-purity magnesium oxide and other materials. Their material structure is dense and not susceptible to damage by high temperature and thermal shock. Therefore, magnesia bricks can withstand high temperatures up to 2000°C and are a very ideal high-temperature refractory material.

Magnesia bricks have good corrosion resistance. In some special high-temperature atmospheres and corrosive media, conventional refractory materials may be corroded and damaged, but magnesia bricks can work in such harsh environments for a long time without being corroded, thus ensuring the continuity of the production process. and stability.

Magnesia bricks also have high compressive strength and tensile strength. This means that even if it is subjected to certain external forces during use, it can withstand these pressures and tensions well and will not break or deform due to external forces.

Magnesia bricks have good thermal conductivity. This is because magnesium has good thermal conductivity and can absorb, conduct and release thermal energy well. Therefore, in high-temperature environments, the use of magnesia bricks can effectively transfer and dissipate heat, thereby ensuring the stability and balance of high-temperature environments.

Products Applications

1. Heat treatment equipment

Magnesia bricks are used in heat treatment equipment such as furnaces, heating furnaces, electric furnaces, boilers, etc., and can play a good role in heat insulation, heat preservation and fire resistance.

2. Metallurgy and chemical industry

Magnesia bricks are also widely used in glass, metal, ceramics and other industries, such as electrolyzers, kilns, glass kilns, regenerators, etc. They have excellent acid and alkali corrosion resistance, excellent electrical and thermal conductivity, and extremely high physical properties and pressure resistance.

3. Building materials

Magnesia bricks can also be used in construction, rail transit and other fields. In the construction industry, they are often used in partition walls, heat insulation, floor linings, fire isolation walls, exterior wall insulation, etc.
