Product description
Fire clay block have strong corrosion resistance: clay and kaolin in clay refractory brick materials contain high silicate and aluminate, which can resist various acids, alkali, salt and other chemical corrosion, so it is widely used in chemical industry, metallurgy, electric power and other fields.

Advantages of fire clay block
Metallurgical industry: fire clay block can be used in iron furnaces, steel furnaces, blast furnaces, ladle, converter, electric furnaces and other metallurgical equipment lining, furnace bottom, hot air duct and other parts.
Chemical industry: fire clay block can be used in oil refining, fertilizer, ethylene and other chemical equipment lining, reactors, pipelines, heating furnaces and other parts.
