Description

Technical Field

[0001] This utility model belongs to the field of burn-through device technology, specifically relating to a burn-through device that extends the service life of busbars. Background Technology

[0002] An electric arc burn-through device is a specialized piece of equipment used in submerged arc reduction furnaces (SAFs) for producing ferroalloys. It utilizes an electric arc to burn open the taphole. Depending on the furnace capacity, the number of tapholes, and whether the furnace rotates, various types of burn-through devices are available to adapt to the furnace operation. The simplest type involves placing a graphite or carbon electrode horizontally in front of the taphole and connecting it to the burn-through busbar. When burning through the taphole, an iron rod is placed on it, creating an electric arc between the rod and the carbon brick-lined taphole, thus achieving the burn-through effect.

[0003] The existing installation method for fixing the busbar and the burn-through device is to use parallel docking at the top and bottom. In this method, the busbar moves back and forth with the burn-through device during operation, which causes shearing force between the copper wires and the copper plate of the busbar. This results in a short service life of the busbar due to broken copper wire strands, which not only increases the workload of replacement but also increases production costs, seriously restricting calcium carbide production. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a burn-through device for extending the service life of busbars, which features both extended busbar service life and reduced calcium carbide production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a burn-through device for extending the service life of a busbar, comprising a copper busbar with several assembly screw holes on one side, a bent portion in the middle of the copper busbar, and busbar screw holes symmetrically provided at the end of the copper busbar away from the assembly screw holes.

[0006] Preferably, the edges of the busbar screw holes are polished to a neat finish.

[0007] Preferably, the busbar screw hole is a lateral opening inside the wiring copper busbar.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention involves bending the copper busbar at the required angle to form a bent section. Then, according to the running direction of the burn-through busbar, symmetrical busbar screw holes are opened inside the copper busbar at the required angle. The edges of the busbar screw holes are ground neatly to reduce busbar wear. This minimizes the shear force on the burn-through busbar during use, extends its service life, prevents damage due to broken copper strands, increases the busbar's service life, reduces the workload of busbar replacement, saves production costs, and improves calcium carbide production efficiency.
