Description

Technical Field

[0001] The utility model relates to a crucible device for a 12-ton vacuum induction furnace, and more specifically to a crucible water-cooling cable bracket for the 12-ton vacuum induction furnace. Background Art

[0002] The crucible of the 12-ton vacuum induction furnace used for special smelting is powered by six water-cooled cables. The water-cooled cable is a hollow cable that passes water and is used for high-current heating equipment. It is usually composed of three parts: an electrode (cable head), a conductor, and an outer sheath tube. The conductor is mostly made of copper and is easily broken due to excessive bending. However, during the use of the crucible, it is necessary to rotate around the crucible shaft to facilitate pouring out the molten metal raw materials in the crucible. The water-cooled cable will also bend during the rotation of the crucible, causing the water-cooled cable to bend. When the water-cooled cable is bent, the internal copper conductor will break, affecting its service life. In the process of the crucible rotating, the water-cooled cables are prone to friction with each other, which will cause wear of the water-cooled cables, reduce the service life of the water-cooled cables, and increase the cost of use.
