Abstract:

The refractory plastic based on calcined hard clay is prepared with calcined hard clay, pyrophyllite and clay. The physical properties of the refractory plastic based on calcined hard clay and of the refractory plastic based on bauxite are compared and analyzed. The result shows that the physical properties of the refractory plastic based on calcined hard clay are slightly lower than those of the refractory plastic based on bauxite, but its production cost is lower. The refractory plastic based on calcined hard clay can be substituted for part of the refractory plastic based on bauxite and used at the roof area in the low temperature zone and flue area of heating furnace, with good application result.
