the silicon carbide refractory mortar used in the construction of silicon carbide bricks has a low content of silicon carbide in its aggregate (weight% <70%). This kind of refractory mortar has poor resistance to molten metal penetration and alkali corrosion, and a large amount of water is added during construction to obtain good construction performance. This results in a large amount of water vapor during the drying process, which is not conducive to the operation of the kiln. Although some manufacturers use organic matter and furan resin as the binder of refractory mortar, the content of silicon carbide in the aggregate composition of refractory mortar is lower, only 10% to 25%. Although, as refractory mortar for building silicon carbide bricks, it cannot meet the requirements in terms of resistance to molten metal penetration and alkali corrosion.
