Fireclay, high-Al, Corundum Refractory plastic with good plasticity for Industrial furnaces
Refractory plastic uses refractory aggregate and powder, clay and chemical compound agent and additive, mixing, extrusion into adobe shape by the preparation, it is with certain plasticity that can be constructed by ramming method. Refractory plastic is made by mixing water (or liquid containing binder) with a certain size of refractory, binder and admixture.According to the main materials of plastic composition, Refractory plastic can be divided in clay, high aluminum, silicon, semi-silicon, corundum refractory plastic.
Refractory plastic will still has good plasticity after stored in the packaging at a certain period of time.
And with characters of good thermal shock resistance, convinent construction.
Refractory plastics are mainly used as liners for various heating furnaces, equalizing furnaces, annealing furnaces, sintering furnaces and electric furnace arch in iron and steel industry.
