Wear Resistant Fire Proof 1.2g/cm3 Clay Insulating Brick
Standard sizing:This brick is special size for pipes of industry furance ,Special size and OEM Service also provide!
The size is precise, providing kinds of shapes according to customer's drawing
Definition:
Lightweight Fire Proof Refracotry Brick were mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
Lightweight refractory bricks Advantage:
1. Low thermal conductivity, good thermal insulation performance.
2. Long service life, easy operation, could be shaped freely
3. Product specification: standard form, normal standard, shaped and special shaped bricks.
4. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.
Application:
Lightweight Fire Proof Refracotry Brick is widely used as a primary hot face refractory lining or as back-up insulation behind other refractories in furnace(such as carbon furnace,cracking furnace,heating furnace for oil refining,roller kiln, tunnel kiln.),flues, flues,refining vessels, heaters,regenerators and similar high temperature industrial equipment.p.
