Abstract
A method for cooling furnace electrodes using a cooling liquid containing surfactants. This method can be applied to electrodes used in electric arc furnaces and ladle metallurgy furnaces. The method can involve spraying the cooling liquid onto the electrode, thereby lowering the temperature of the electrode and reducing electrode consumption.
Claims14
A method for cooling a furnace electrode, comprising:
- mixing a surfactant with water to form a cooling liquid so that the surfactant is present in the cooling liquid in an amount in a range of from 10 mg/l to 5,000 mg/l, and the surface tension of the cooling liquid is in a range of from 54.9 mN/m to 69.5 mN/m at room temperature, and
- spraying at least a surface of the furnace electrode disposed adjacent a furnace with the cooling liquid to cool the furnace electrode.
