Refractory Bricks
High Alumina light weight Poly brick for Insulation

High Alumina light weight Poly brick for Insulation

High aluminum poly light brick for ceramic kiln, trolley furnace, heat treatment furnace on the lining of the weight and fire resistance have both the requirements of the furnace, high aluminum poly light brick is a light refractory brick, fire resistance 1300 ~ 1500 ,have the excellent resistance to burning performance and insulation performance.

High aluminum poly light brick with low thermal conductivity, high compressive strength, good thermal stability and other characteristics, is a new alternative to imports of energy-saving refractories. 0.6 high aluminum poly brick is widely used in metallurgy, chemical, petroleum, machinery, textile, light industry, building materials, electricity and other industries widely used, energy saving effect is very significant. After firing the product, grinding and shaping, the size of the error is small, to meet the requirements of various construction.

Advantages of 0.6 high aluminum poly brick

(1) low thermal conductivity, especially in high temperature conditions, the thermal conductivity is relatively low, thermal insulation performance.

(2) 0.6 high aluminum poly light brick thermal shock resistance, in the use of temperature range, the brick is not deformed, do not peel off.

(3) according to the use of different, choose a reasonable mechanical strength, so that the best performance of light brick.

(4) higher load softening temperature and smaller re-burning rate of change, compared with similar materials, lightweight refractory brick, 0.6 high aluminum poly brick with a higher temperature, longer life, more secure.
