Problems solved by technology

For example, high-speed tool steel, when the steel ingot size is large, even if the melting speed is very low, the carbide size is too large and the segregation exceeds the standard, which seriously affects the quality of the steel.
[0005] 3. Traditional electroslag remelting adopts the intermittent production method of remelting one steel ingot at a time, which not only has low production efficiency, but also removes a large amount of the head and tail of the steel ingot during the subsequent forging or preliminary rolling blanking process, and the yield of steel Very low and thus high production costs

Description

technical field [0001] The invention belongs to the technical field of metal electroslag remelting equipment, in particular to a continuous casting electroslag furnace, which is applied in the metal remelting 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 for smelting. Steel smelted by electroslag furnace has the advantages of high purity, low sulfur content, less non-metallic inclusions, smooth surface of steel ingot, uniform and dense crystallization, uniform metallographic structure and chemical composition. Therefore, electroslag furnace equipment has been widely used in steel, machinery and other industries at home and abroad. With the development of electroslag equipment, there are the following main defects in the melting of small diameter steel ingots: [0003] 1. In the traditional electroslag furnace smelting process, the ...
