LG0.9Insulation Brick High Alumina Insulating Refracotry Brick
The Description:
In blast furnace hot blast furnace, the common heat-insulating bricks are mainly high aluminum heat-insulating bricks and clay heat-insulating bricks. High aluminum heat insulation brick is made of aluminum rock soil as the main raw material of AI203 content of not less than 48% heat insulation refractory products. GB3995-1983 The high aluminum heat insulation brick is divided into LG-1.0, LG0.9, LG-0.8, LG-0.7, LG-0.6, LG-0.5 and LG-0.4 grades according to the volume density.

Product feature:
(1) Low thermal conductivity, especially in the high temperature state, the thermal conductivity is relatively low, and the thermal insulation performance is good
(2) Good thermal shock resistance, in the use of temperature range, the brick does not deform, do not flake.
(3) According to different uses, the selection of reasonable mechanical strength, so that the light brick performance is the best
(4) Higher load softening temperature and smaller heavy burning line change rate, compared with similar material light brick, higher use temperature, longer life, more safe
(5) Short production cycle and large production capacity
