85% Al2O3 Corundum Castable Refractory Anti-wear Self-flow dense Castable for
CFB boiler
Corundum Anti-wear self-flow castable produced by us uses corundum aggregates as the main material, added with various of admixture and high efficiency watering reducing agents, liquid agents to enhance the flowing property. In the construction process, mixing dry material and additive (admixture, adhesive) by the mixer for 1-3 minutes, then stirring with water (the water content: about 5.5%, Ph6-8).
Corundum Anti-wear self-flow castable main characters:
1, In the case of not increasing water consumption, the product can flow only depends on the self-weight and potential energy difference,
2, In the state of non-vibration, the construction can be done in the places of clamps and unshakeable areas, which has a good quality of construction.
3, The product with high wear-resistance, high-temp resistance, strong impact, high thermal shock resisatanc, good self-flow property.
Corundum Anti-wear self-flow castable Application:
Mainly used for the difficult construction, wearing and tearing badly parts of the lining of CFB boiler and other thermal equipment. Also widely used in metallurgical industry, non-ferrous metal industry, petro chemical industry, cement industry and building industry etc.
