Description
Technical field
This utility model relates to girder steel chiller, belongs to industrial high power electric furnace field.
Background technology
LF stove in high-power, large-current electric stove, such as steel industry in industry, mineral hot furnace etc. in ferroalloy industry,
When building steel-structure factory building inside in, near the girder steel of high-current cable, owing to high-current cable produces powerful alternating magnetic field,
Make girder steel produce faradic current heating, reduce the bearing capacity of girder steel, the problem jeopardizing building safety.Unavoidably going out
During existing this situation, existing method is, uses austenite magnetism-free stainless steel, girder steel is made cavity, and cavity inside leads to
Water cooling.Water flowing cooling can solve this problem, but owing to girder steel heating does not reduce, wastes the energy；Meanwhile, cooling water
Girder steel can be corroded, after longtime running, entail dangers to building safety；Meanwhile, girder steel leaks after being corroded through, and makes safety in production
Become serious threat.
As it is shown in figure 1, furnace transformer is arranged on girder steel, high-current cable produces alternating magnetic field, girder steel cutting alternation
Magnetic field, produces faradic current, and girder steel generates heat, and reduces steel beam structure stability.Prior art is, uses austenite without magnetic
Rustless steel, makes cavity by girder steel, and cavity inside water flowing cools down.Water flowing cools down, and the method has the advantages such as simple and practical,
But owing to girder steel heating does not reduce, waste the energy；Meanwhile, cooling water can corrode girder steel, after longtime running, entail dangers to
Building safety；Meanwhile, girder steel leaks after being corroded through, and safety in production is caused serious threat.
Utility model content
Utility model purpose: in order to overcome the deficiencies in the prior art, this utility model provides a kind of girder steel cooling dress
Putting, by being enclosed with aluminium sheet on girder steel, aluminium sheet has high conductivity, produces faradic current and induced field, offsets big
The magnetic field that current cable produces, makes the magnetic field through girder steel significantly reduce, and the induced current of generation and caloric value are the most significantly
Degree reduces.
Technical scheme: for solving above-mentioned technical problem, a kind of girder steel chiller of the present utility model, including aluminium sheet, institute
Stating aluminium sheet is U-shape, and the aluminium sheet of U-shape is wrapped on girder steel, and the opening of the aluminium sheet of U-shape deviates from high-current cable.
As preferably, the thickness of described aluminium sheet is 2～50mm.
As preferably, it is the passage that non-magnet material non-conducting material makes that described aluminium sheet is externally provided with material.
As preferably, the cross section of described passage is rectangular ring, and the end at passage is provided with extractor fan.
As preferably, the initiating terminal of described passage is provided with air-blast device.
Beneficial effect: girder steel chiller of the present utility model, utilizes the high conductivity of aluminium sheet, produces faradic current and sense
Answering magnetic field, offset raw magnetic gradient, make the magnetic field through girder steel significantly reduce, induced current and the caloric value of generation are the biggest
Amplitude reduces；Aluminium sheet resistance is little simultaneously, and caloric value is little, reduces energy waste；Use ventilation cooling structure girder steel simultaneously,
Improve steel beam structure stability further, improve building safety, there is simple in construction, the advantages such as exploitativeness is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing chiller.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
As in figure 2 it is shown, a kind of girder steel chiller of the present utility model, including aluminium sheet 5, described aluminium sheet 5 is U-shape,
The aluminium sheet 5 of U-shape is wrapped on girder steel 2, and the opening of the aluminium sheet 5 of U-shape deviates from high-current cable 3.Described aluminium sheet 5
Thickness be 2～50mm, the thickness of aluminium sheet 5 according to electromagnetic induction calculate determine.It is non-that described aluminium sheet 5 is externally provided with material
The passage 4 that permeability magnetic material non-conducting material makes, the cross section of described passage 4 is rectangular ring, and the end at passage 4 is pacified
Equipped with extractor fan, the initiating terminal of passage 4 is provided with air-blast device.
In this utility model, girder steel 2 uses low permeability stainless steel, aluminium sheet 5 to use the above purity of commercial-purity aluminium
Aluminum, between aluminium sheet with aluminium sheet use low resistance electrical is connected, formation electrical loop.
In this utility model, furnace transformer 1 is arranged on girder steel 2, arranges between girder steel 2 and high-current cable 3
Aluminium sheet 5, calculates the thickness determining aluminium sheet 5 by electromagnetic induction, and aluminium sheet 5 uses the aluminum of the above purity of commercial-purity aluminium, by
In aluminium sheet, there is high conductivity, produce faradic current and induced field, offset the magnetic field that high-current cable 3 produces, make to wear
The magnetic field crossing girder steel significantly reduces, and induced current and the caloric value of generation the most significantly reduce.Aluminium sheet resistance is little simultaneously,
Caloric value is little, reduces energy waste.For improving girder steel safety further, utilize with non-magnet material non-conducting material 4
Around girder steel and aluminium sheet, form passage, by convulsion or air blast mode, make air from passage by aluminium sheet and girder steel being produced
Heat take away
The above is only preferred implementation of the present utility model, it should be pointed out that: for the ordinary skill of the art
For personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
