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 products,etc.
Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.
Refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.
