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％、添加剂3～5％；将上述原料混合均匀后，加水调成浆料，喷涂在翻渣溜槽表面，喷涂厚度为2～6mm，喷涂后静置1～5h。本发明的方法通过在溜槽上涂布防粘结涂料，解决了高炉渣热渣入炉过程中溜槽粘结严重、清理难度大的问题。
