Corundum Self - Flow Castable Refractory 80% Al2O3 dense wear resisting castable for CFB bolier
Corundum self-flow wear-resisting castable 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.
Corundum self-flow wear-resisting castable main characters:
In the case of not increasing water consumption, the product can flow only depends on the self-weight and potential energy difference, and 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. It’s the self-flow castable with high wear-resistance, high-temp resistance, strong impact, high thermal shock resisatanc, good self-flow property.
Corundum self-flow wear-resisting castable Application:
Mainly used for the difficult construction, wearing and tearing badly parts of the lining of CFB boiler and other thermal equipment. And widely used in metallurgical industry, non-ferrous metal industry, petro chemical industry, cement industry and building industry etc.
Corundum self-flow wear-resisting castable Construction:
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).
