B-1 Lightweight Refractory Insulation Brick for Chemical Fertilizer Plant

 

Fireclay insulating brick is made of light weight fireclay and widely used for industrial furnace insulation, it has the following features:

1. Light weight and low thermal conductivity allows thinner furnace walls
2. Maintain stable structural strength throughout ambient to maximum service temperature
3. Low heat storage results in rapid cooling and heating operation
4. High thermal shock resistance in preventing spalling

5. Low iron and impurities to enhance reducing atmosphere

 

Advantages:

1. Low cost,high performance and price ratio.

2. High carbon content.

3. Mature technology.

4. Different brands magnesia carbon bricks are available according to the smelting conditions and the kind of smelting steel.
