The application of refractory castables in cement rotary kiln.
According to the different working environment of the furnace, the application of refractory castables are ordinary refractory castables, low cement refractory castables, ultra-low cement refractory castables, cementless refractory castables, steel fiber refractory castables, anti-explosion refractory castables, anti-crust refractory castables, phosphate refractory castables, alkali-resistant castables, heat-insulating castables, in addition, there are new castables such as self-flow refractory castables.
2.Application of refractory castables in glass furnace.
Due to the requirements of the working environment of the glass furnace, the refractory castables used should have the characteristics of good high temperature resistance, strong resistance to liquid glass erosion and low porosity.
3.Application of refractory castables in metallurgical industry.
( 1 ) Refractory castables for ironmaking system
( 2 ) Refractory castables for hot metal pretreatment
4.refractory castables for electric furnace steelmaking
The application of refractory castables in electric furnaces is mainly concentrated in the cover of electric furnaces. The overall prefabrication technology of castables is widely used in the electric triangle area. The overall castable cover may become a development trend of electric furnace cover materials in the future.
5. Refractory castables for secondary refining
( 1 ) Refractory castables for RH furnace.
( 2 ) Refractory castables for LF furnace.
3 ) Refractory castables for CAS refining device.
4 ) Refractory castable for ladle.
6.refractory castables for continuous casting
The castables for tundish are : lightweight castables ( mainly used for insulation layer ), high alumina or mullite self-flow castables corundum and magnesia castables ( used for bottom working layer ).
