Anti-bonding method for blast furnace slag chute

The invention discloses an anti-bonding method for a blast furnace slag chute. The anti-bonding method comprises the following steps: coating a chute with an anti-bonding coating, wherein the anti-bonding coating is prepared from the following raw materials in percentage by weight: 30-50% of carbonized slag dedusting ash, 20-30% of quick lime, 20-30% of waste graphite electrode powder, 1-5% of fluorite powder and 3-5% of an additive; and after the raw materials are evenly mixed, adding water to prepare slurry, spraying the slurry on the surface of the slag turning chute, controlling the spraying thickness to be 2-6 mm, and conducting standing for 1-5 h after spraying. According to the method disclosed by the invention, the anti-bonding coating is smeared on the chute, so that the problems that the chute is seriously bonded and the cleaning difficulty is high in the hot blast furnace slag feeding process are solved. 本发明公开了一种高炉渣溜槽防粘结方法，在溜槽上涂布防粘结涂料；其中：防粘结涂料包含以下重量百分比的原料：碳化渣除尘灰30～50％、生石灰20～30％、废石墨电极粉20～30％、萤石粉1～5％
