Medium Duty Fire Bricks

Basic Overview of Medium Duty Fire Bricks

Medium refractory bricks are aluminosilicate refractory products containing 34-40% alumina. They are made of high-quality bauxite raw materials by dry pressing and fired under tunnel kilns. Therefore, they have excellent refractory properties and mechanical strength.

In addition, we mainly use them for the lining of various industrial furnaces. According to different application requirements, we roughly divide medium refractory bricks into silica firebrick, high alumina brick and magnesia brick. Moreover, Keri can customize the composition, shape and size of refractory bricks according to different working environments of customers.

Significant Performance Advantages of Medium Fire Brick

Medium refractory bricks have a variety of characteristics and properties. In addition to medium refractory bricks, Keri also sells super duty fire brick, thin fire brick, curved fire brick and anchor brick. The characteristics of medium refractory bricks mainly include the following aspects:

• Refractory performance: medium fire brick can withstand thermal expansion and cold contraction in high temperature environments. Therefore, it is not easily affected by thermal stress and thermal shock.
• Wear resistance: this refractory brick has good wear resistance. It can resist the impact and wear of materials and extend the service life of equipment.
• Chemical stability: medium duty firebrick can resist the erosion of corrosive gases and liquids and keep their physical and chemical properties stable.
• Dimensional stability: Kerui medium fire brick and thin fire brick have good dimensional stability and are not prone to deformation and cracking. That is, they can ensure the stable operation of equipment.

Manufacturing Process of Medium Duty Fire Bricks

Kerui Company uses high-quality raw materials and advanced technology for production. The main raw materials include high-alumina bauxite, aluminum silicate, alumina, etc. We strictly screen and proportion these materials to ensure that the finished products have excellent refractoriness and stability. Such as high alumina refractory bricks, aluminum silicate bricks, etc. During the manufacturing process, Kerui uses advanced molding, drying and sintering processes to ensure that each refractory brick has a high density and uniform structure. As a result, this greatly improves its durability and resistance to thermal shock.
