Product Description:

CNBMis the specialized manufacturer and supplier of refractory in China, Our products mainly include refractory bricks, refractory castable, refractory precast shape, insulating brick etc. For refractory castable and precast shape they are very popular in the Europe, North American area.

Advantage:

This series of products are made of super calcined flint clay and calcined bauxite, with high pressure formed and high temperature sintered. Due to its low apparent porosity, strong resistance to erosion and high refractoriness under load, they are wildly used in various furnaces, especially suitable to the middle and low parts of regenerator in glass furnaces.

Features:

1. Low bulk density, low thermal conductivity, good thermal performance.

2. Refractory category allow direct contact of fire, suitable for various atmosphere

3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely

Typical Applications:

1. Furnaces of metallurgy industry, heat treatment furnace

2. Furnaces of chemical industry and construction industry.

3. Furnace of incineration of garbage, recirculating fluidized bed furnace
