Description

technical field [0001] The invention relates to a multi-station coaxial electroslag furnace short net device, which belongs to the technical field of special metallurgical equipment. Background technique [0002] With the rapid development of the material industry at home and abroad, the demand for large-tonnage high-end smelting equipment is increasingly strong. Therefore, large-scale electroslag remelting furnaces emerged as the times require, and the country vigorously advocates energy-saving and green environmental protection industries, so the traditional design and manufacturing technology is difficult and costly. [0003] 1. The domestic traditional electroslag furnace equipment is single-column support arm type, double-column rotating support arm type double-station electroslag furnace, the support arm clamp clamps the dummy electrode and the metal electrode, and the transmission device is controlled to rotate the T-shaped screw rod Drive the roller cantilever to mo...

Problems solved by technology

For example, in the process design of electroslag furnace, a large current of 18000A~45000A needs to be passed, so the water-cooled cable needs a large conductive cross-section, and the water-cooled cable manufactured in this way is thick and stiff, which cannot meet the angle and movement of the multi-station rotation of the electroslag furnace equipment. displacement, and the water-cooled cable is susceptible to bending and holding force, resulting in blocked water flow or burst tubes, which will affect the electrical conductivity and even lead to more serious consequences

However, the production of water-cooled cables with large cross-sections is difficult, the production cost is high, and the installation and daily maintenance are inconvenient.

In addition, water-cooled cables are used in many places on the furnace body as soft connections to conduct electricity, so that the water-cooled cables need a relatively large installation space during installation, so the short network cannot be effectively implemented as coaxial or parallel wiring, thus increasing the cost per ton. Electricity consumption of steel and increased production costs
