Phosphate refractory clay is a refractory clay with phosphate as the main component, which has good bonding and refractory properties. It is widely used in furnace joints in industries such as steel, glass, ceramics, and cement. ·Good bonding: It can effectively bond refractory bricks to ensure the integrity of the furnace. ·Good refractory performance: It has high refractoriness and is suitable for high temperature environments. ·Chemical corrosion resistance: It can effectively resist chemical corrosion and is suitable for harsh environments.
Steel Industry: used in the joints of blast furnaces and hot blast furnaces.
Glass Industry:used in the joints of glass melting furnaces.
Ceramics Industry: used in the joints of ceramic kilns.
Cement Industry: used in the joints of cement rotary kilns.
