Refractory gunning mix is a kind of unshaped refractory material used for gunning construction with jet machine. It is composed of refractory aggregates and powders with a certain particle size, binding agent and admixture. According to the material, there are alkaline, aluminum silicate, zirconium-containing and silicon carbide-containing. Refractory gunning mix is mainly used for repairing of steel and non-ferrous metal smelting furnaces and heating furnaces.
1. According to the composition of the gunning material, it is divided into: high aluminum, high silicon, magnesia, magnesium chromium, silicon carbide, etc.
2. According to the state of refractory materials, it can be divided into: dry, semi-dry and wet gunning. If the corrosion surface of the furnace lining is larger, the wet method is better for hot gunning; the dry method is more to fill the severely corroded parts of the situation. .
3. According to the temperature of gunning delivery gas, it can be divided into cold and hot gunning.
