company news about The characteristics and application of lightweight thermal insulation refractory brick

Compare light heat preservation and heat insulation refractory brick and common refractory brick ,light weight, has uniform tiny voids internally , porosity is higher,so it can guarantee the less heat of furnace wall smaller ,  the fuel costs will be reduced, light brick also means that smaller storage quantity of heat, so the heating and cooling will be faster, allowing accelerated the cyclic operation.Lightweight heat insulation refractory brick is suitable for the 900 ℃ ~ 1650 ℃ temperature range.heat preservation and heat insulation brick have following product feature: 1, the low thermal conductivity, low thermal capacity, low impurity content. 2, the high strength, a good thermal shock resistance, resistanced to acid and alkali corrosion atmosphere 3, the high dimensional accuracy Lightweight insulation refractory products used: 1, all kinds of industrial furnace heat surface lining materials, such as: annealing furnace, carbide furnace, tempering furnace, refining furnace, furnace, roller kiln, tunnel kiln, etc.2, all kinds of industrial furnace backing insulation materials.3, reducing atmosphere of furnace.
