Compared with ordinary refractory bricks, lightweight insulation bricks are lighter in weight, tiny pores are evenly distributed inside, and have higher porosity. So, it can guarantee less heat is to be lost from the furnace wall, and fuel costs are reduced accordingly. Lightweight bricks also has less heat storage, so both heating up and cooling down of furnace built with lightweight bricks are faster, allowing faster cycle times of furnace. Lightweight thermal insulation refractory bricks are suitable for the temperature range of 900 ℃ ~ 1650 ℃.
Characteristics of lightweight insulation brick
1. Low thermal conductivity, low heat capacity, low impurity content
2. High strength, good thermal shock resistance, good corrosion resistance in acid and alkali atmosphere
3. High dimension accuracy
Application of lightweight insulation bricks
1. Various industrial furnace hot surface lining materials, such as: annealing furnace, carbonization furnace, tempering furnace, oil refining heating furnace, cracking furnace, roller kiln, tunnel kiln, etc.
2. Backing insulation material for various industrial furnaces.
3. Reducing furnace.
