[0002] Electroslag (Smelting Casting) is a secondary refining technology, a comprehensive metallurgical casting process that combines secondary refining of molten steel with directional solidification. Its principle is that electric current passes through the liquid slag pool to resist heat, melting the metal electrode. The molten metal gathers into molten droplets, which drip through the slag layer into the molten metal pool, and then crystallize and solidify into steel ingots in a water-cooled crystallizer.

[0003] During the production of electroslag ingots, electric drying furnaces are needed to dry ingredients such as quicklime, fluorite and refractory materials. However, existing electric drying furnaces lack devices that can flip the internal ingredients.
