Pressed-in sealant for blast furnace and preparation method thereof
The invention provides a pressed-in sealant for a blast furnace and a preparation method thereof and aims to solve the problem that existing sealants have a poor densification effect. The pressed-in sealant successively comprises, by weight, high aluminium bauxite, gangue, pyrophillite, flint clay, kyanite, clay, high alumina bauxite powder, silicon carbide powder, quartz powder, graphite and modified sliicon-alumininm sol. The prepared sealant matrix has high content and good fluidity, can slowly wriggle in a small slit and has good permeability. The modified sliicon-alumininm sol has short bonding and hardening time, the strength is suitable, and a hardened product has elasticity and will not become hard and fragile or crack. The product has good endophilicity and excellent seal performance, and is firmly glued with a steel casing and a furnace lining to form an integral body so as to greatly prevent gas from fleeing along the slit.
