Plastic is an amorphous refractory material in the form of hard mud paste, which is made by fully mixing refractory aggregate and powder, plastic clay, binder and admixture.
It has high plasticity and can maintain this state for a long time.
(1) Good plasticity
(2) Easy to construct
(3) Good thermal shock resistance
(4) Good volume stability
(5) Good fire resistance
(1) Metallurgical industry: heating furnace, smelting furnace, heating furnace, soaking furnace, annealing furnace, sintering furnace, electric furnace, kiln
(2) Chemical industry: production of catalysts, heat exchangers, reactors
(3) Power industry: production of boiler furnace walls, flues, furnaces
(4) Other fields: flue lining, chimney lining, kiln car, ladle
