Description

High-power intermediate frequency furnace induction coil

Technical field

The utility model is related to a kind of intermediate frequency furnace induction coil, more particularly to a kind of more than 4.2MW high-power intermediate frequency furnace Induction coil.

Background technology

Intermediate frequency furnace has the advantages that firing rate is fast, production efficiency is high, oxidation and decarbonization is few, die life is long, not only Production material and cost can be saved, relative working environment is also preferable, the characteristics of with pollution-free, low power consuming, therefore enjoyed The favor of each steel-making enterprise.The intermediate frequency furnace of large-tonnage improves production efficiency, it is necessary to high-power output can just shorten the heat, Smelting cost is reduced, and to improve the power output of intermediate frequency furnace, must just there is corresponding intermediate frequency furnace induction coil, but at present The most power of intermediate frequency furnace induction coil it is smaller, it is impossible to meet the use requirement of high-power intermediate frequency furnace.

The content of the invention

The utility model in order to overcome intermediate frequency furnace induction coil can not meet the use requirement of high-power intermediate frequency furnace there is provided A kind of high-power intermediate frequency furnace induction coil, to improve intermediate frequency furnace power output, improves production efficiency, reduces smelting cost.

The utility model is realized using following technical scheme：High-power intermediate frequency furnace induction coil, by multiturn helical form square Shape copper pipe alternating spiral is constituted together, is isolated between every rectangle copper pipe using insulation board；The multiturn helical form rectangle copper Pipe, has two groups of conductive components, multichannel circulating cooling water route per circle；Spiral helicine rectangle copper is included per circle helical form rectangle copper pipe Pipe, water supply connector, conducting block, conductive elbow, conductive contact, contact tube and insulation pipe clamp.The water supply connector, conducting block, Conductive contact, contact tube and helical form rectangle copper pipe are welded.

Further, described spiral helicine rectangle copper pipe using many rectangle oxygen-free copper pipes to postwelding, in the direction of the clock Bending winding, ensures that the spacing between every circle copper pipe is equal during bending winding；Butt welding between rectangle copper pipe is protected using helium TIG weld；Described water supply connector is located on the outside of helical form rectangle copper pipe, using welding manner and the helical form rectangle of silver brazing Copper pipe is connected.

Further, described conductive contact, contact tube be located at helical form rectangle copper pipe on the outside of, by conducting block by its with Helical form rectangle copper pipe welds together, and is reinforced by the pipe clamp that insulate.

The utility model has the following advantages：The high-power intermediate frequency that multiturn helical form rectangle copper pipe alternating spiral is constituted together Stove induction coil, can improve the power output of intermediate frequency furnace, improve production efficiency；Every two groups of conductive components of circle and multichannel circulation are cold But water route can reduce coil electric furnace, improve cooling effect, reduce smelting cost；Butt welding between rectangle copper pipe is protected using helium TIG weld is protected, coil can be caused to have longer service life, production needs are met, it is adaptable to high-power intermediate frequency furnace.
