[0002] The metallurgical electric furnace has a very high internal heat when it is used. Although the external heat is relatively small, if no external cooling treatment is performed, it may still affect the external environmental temperature and even affect the use and life of external instruments and meters. In addition, if other workers are close to the production area and do not understand the characteristics of the metallurgical electric furnace, there is a risk of scalding. Therefore, many companies will protect the outside of the metallurgical electric furnace and design a water-cooled structure to quickly cool it down. However, the existing water-cooling structure and the water-cooling box connector are not easy to disassemble, and the water-cooling system needs to be cleaned and maintained regularly, otherwise it is prone to corrosion and blockage. The regular cleaning and maintenance of the water-cooling system brings trouble to the maintenance and repair of the metallurgical electric furnace. To this end, a water-cooling device for an electric furnace for metallurgical production is proposed. Utility Model Content
