This king of products is sintered mainly with supper-fine bauxite charlotte and propr additive by a method of EPS ignition loss. 

 

insulating fire bricks advantages

 

1. high intensity,

2. low thermal conductivity, 

3. excellent thermal stability, 

4. very small reheat linear change, 

5. outstands erosion and corrosion resistance etc. 

 

Application: They are an ideal kind of energy conserving products, which can be widely used as lining or insulating layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry, chemical industry, etc. 

 

Note: Recommended to use below 1400OC.
