GAOQING XINPENG is the specialized manufacturer and exporter of insulation and refractory material with more than 10 years' history. The products include refractory brick, refractory casable, insulating brick, ceramic fiber etc. Our refractory bricks primarily export to AMERICA, ITALY, MIDDLE EAST, SOUTHEAST ASIA, etc.

 

Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, it’s an important material for high-temperature services, mainly used for industrial furnaces and kilns and thermal equipments.

 

Highlight:

•Good thermal shock and thermal spalling resistance.

•High mechanical strength.

•Good resistance to abrasion and corrosion.

•Good volume stability at high temperature.

 

Application:

Industrial furnaces and kilns and thermal equipments.

Metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.
