Product description
Jm23 brick insulation brick: refers to the Al2O3 content of 50%-85% light firebrick, with mullite as the main crystalline phase and the combination of high quality insulation materials. The main characteristics are: high strength of high temperature structure, low creep at high temperature, small thermal expansion coefficient, strong floc resistance, excellent thermal shock resistance. According to the different aluminum content and volume density, the use of temperature of 1350-1700℃, can directly contact the flame furnace working layer lining.
Advantages of jm23 brick:
Low density: High alumina poly light bricks use lightweight aggregate as the main raw material, making them less dense. Compared with traditional refractory bricks, it is lighter in weight, reduces structural load, and facilitates construction and transportation.
Erosion resistance: High alumina poly light bricks can resist acid and alkali corrosion and metal oxide corrosion. It is suitable for various industrial environments and can ensure the integrity and stability of the furnace structure.
Application of jm23 brick
◆Ceramic tunnel kiln
◆Roller kiln and shuttle kiln
◆Furnace lining and insulation layers
◆Other Thermal Equipment & Heat Treatment Lining
◆Heating Furnace & Coking Furnace In Iron And Steel Industry

Packages and delivery:
Because jm23 brick with smaller bulk density whose strength is not as strong as heavy weight fire bricks, when delivering, CH Refractories will package insulating firebricks with special packages to protect insulating clay bricks from damage.
