Description

technical field [0001] The invention belongs to the technical field of metal electroslag remelting equipment, and particularly relates to a slab electroslag furnace, which is applied in the metal remelting smelting process. Background technique [0002] The electroslag furnace is a metallurgical equipment that uses the resistance heat generated when the current passes through the slag as a heat source to smelt metal. After electroslag remelting, the content of gas and inclusions in steel can be reduced, and a steel ingot with uniform composition, compact structure and excellent quality can be obtained. The plasticity and toughness of the alloy, especially the transverse properties are improved, the anisotropy is reduced, and various macroscopic and microscopic defects are eliminated or alleviated. Therefore, electroslag furnace equipment has been widely used in steel, machinery and other industries at home and abroad. [0003] At present, domestic electroslag furnaces main...
