Castable for torpedo tank
The castables for torpedo tank include corundum aggregate, fine powder, SiC, kyanite, micropowder, composite antioxidants and composite additives.
The castable material has higher high-temperature strength under the premise of ensuring good flow performance and good bonding strength with the old brick surface, improving the slag-resistant iron oxidation erosion and scouring performance of the castable, and reducing the slag-hanging ability.
The construction performance and simple construction process can meet the needs of torpedo liner lining repair, reduce the incidence of bursting and peeling during baking, and have good thermal shock resistance.
