Silicone wear-resistant composite brick for transition zone
Product Description
Silicone wear-resistant composite brick
The brick is a new type of energy saving refractory material developed on the base of silicon wear resistant brick, with wear resistance and insulation performance. The brick is pressed by high pressure and fired at high temperature.with the following performance:
* It consists of two parts: the working layer and the thermal insulation layer.
* excellent anti-erosion performance
* high thermal shock resistance in working layer
* high strength at high temperature
* excellent wear resistance
* thermal insulation layer--lower the kiln body temperature
