Product description
Hot face insulation bricks is made of local top grade fireclay materials under the high temperature according to the lastest national standard. The temperature in the 1200-1400 ℃. Ingredients are mixed with water made of plastic material or mud, mud with extrusion or pouring shape, 1250-1350 ℃ after dry burning oxidation atmosphere. The volume density of commonly used insulated clay brick is 0.75-1.2 g/cm3. There are insulating clay bricks, high alumina insulation brick and mullite jm insulating bricks for insulation layer, which are suitable for different high temperature. Just please inform us your required bricks working temperature, we can provide you the most economical suggestions to you.
Because heat insulating bricks 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.
Advantages of hot face insulation bricks:
Low density: hot face insulation 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.
Excellent thermal insulation properties: hot face insulation bricks have low thermal conductivity, which can effectively isolate heat transfer inside and outside the furnace and improve energy utilization efficiency. At the same time, it can reduce the temperature rise of the outer wall, protect the furnace structure and reduce heat radiation loss.
Application of hot face insulation bricks
◆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
