Description

Technical Field

[0001] This utility model relates to the field of refining furnace cable technology, specifically to a spacer fixing sleeve for water-cooled cables of refining furnaces. Background Technology

[0002] Water-cooled cables are an important component of the refining furnace short network. They are special cables designed to meet the expansion and contraction requirements of cables during electrode lifting, furnace body tilting, and furnace cover lifting and rotation. To prevent friction between adjacent cables, water-cooled cables are generally equipped with protective sleeves. Existing technology describes a protective sleeve for a water-cooled cable in a refining furnace, comprising a rubber sleeve body and a cable tie. The rubber sleeve body has two parallel cable holes that match the water-cooled cable of the refining furnace. An inlet is located on the outer side of the two cable holes. The cable tie is used to secure the water-cooled cable to the outside of the rubber sleeve body. This effectively prevents friction between the protective sleeve and the adjacent water jacket of the water-cooled cable, reduces cable wear, extends the service life of the water-cooled cable, avoids production stoppages caused by water jacket wear, and ensures stable and smooth production. However, in this technology, the water-cooled cable is fixed to the refining furnace through the cooperation of the rubber sleeve body and the cable tie. The inner diameter of the cable holes on the rubber sleeve body is fixed. For cables with smaller diameters, they can easily fall out of the inlet or move within the cable hole, making it impossible to secure the cable. Utility Model Content
