High-temperature-resistant and corrosion-resistant cement gum, high-temperature-resistant and corrosion-resistant smelting furnace blowing elbow air pipe and preparation method thereof

The invention belongs to the technical field of smelting furnace blowing and non-ferrous metal recycling, and particularly relates to high-temperature-resistant anti-corrosion cement gum, a high-temperature-resistant anti-corrosion smelting furnace blowing elbow air pipe and a preparation method thereof. The high-temperature-resistant anti-corrosion daub comprises the following components in percentage by weight: 20-45% of sodium silicate, 10-20% of magnesia powder, 5-20% of aluminum oxide, 3-15% of refractory mortar, 5-15% of stone powder, 2-8% of mullite, 3-10% of lime, 1-5% of gypsum, 1-2.5% of a high-temperature curing agent and 3-10% of water. The high-temperature-resistant and corrosion-resistant smelting furnace blowing elbow air duct prepared from the material has excellent ultrahigh temperature resistance, flame retardance, wear resistance, aging resistance, high temperature resistance, acid and alkali resistance and the like, and the highest temperature resistance is about 1600 DEG C. The high-tempe
