Silicon sol combined corundum-silicon carbide wet-type spray material
The invention belongs to the technical field of unshaped refractory materials. A silicon sol combined corundum-silicon carbide wet-type spray material is characterized by comprising a main raw material and an additive component, wherein the main raw material comprises the following components in percentage by weight: 0%-55% of granular corundum materials, 15%-25% of fine corundum powder, 0%-55% of granular silicon carbide materials, 8%-25% of fine silicon carbide powder and 5%-12% of aluminium oxide micropowder; the additive component comprises the following components based on the total weight of the main raw material in percentage by weight: 1.0%-2.5% of antioxidants, 0.2%-1.0% of retarders, 0.5%-1.2% of dispersing agents, 0.3%-1.0% of coagulants and 8%-12% of silicon sol. The silicon sol combined corundum-silicon carbide wet-type spray material disclosed by the invention has the advantages of good adhesion, low rebound rate, no mould, high continuous construction thickness, fast baking, good heat shock stability, good anti-erosion property, good construction property and environment friendliness, can be used for effectively overcoming the defects of a spray material in the prior art and is suitable for fast repairing the blast furnace hearth, the furnace bosh and the furnace bosh lining.
