Water spraying while steelmaking! This is actually a new electrode protection technology developed first in Japan-water spray electrode protection. This technology uses an annular water spray device under the electrode holder to spray water on the surface of the electrode to make the water flow down the surface of the electrode. Above the electrode hole L of the furnace cover, a ring tube is used to blow compressed air to the current surface to atomize the water. After adopting this method, the electrode consumption per ton of steel has dropped to 0.9-1.2kg. At the same time, the life of the refractory furnace cover is doubled due to the effect of atomized steam.
