Description
Technical field
The present invention relates to a kind of lifting electromagnet, especially relate to a kind of lifting electromagnet of hoisting ultra-high temperature iron and steel.
Background technology
In steel manufacture process,, often want handling to surpass 600 ℃ of hi-heat steel products for the needs of energy savings and some technology.The lifting electromagnet of hoisting ultra-high temperature steel products structurally still adopts traditional lifting electromagnet structure at present, the non-constant of thermal diffusivity, although taked some provision for thermal insulations, but because the magnet coil distance is too near by the extraordinary high temperature steel products of handling, generally in tens millimeter, radiation and conduction heat from the high-temperature steel iron product still can not be cut off in a large number, causes magnet coil to be rapidly heated, and finally causes the handling ability of lifting electromagnet to decline to a great extent.In order to guarantee that lifting electromagnet still can handling high-temperature steel iron product under the situation that the handling ability declines to a great extent, the general a.t. that significantly improves electromagnet, come offset because the ability drop that magnet coil is rapidly heated and causes by handling ability more than needed, make the deadweight of this class lifting electromagnet very big thus, the suction anharmonic ratio is very little.
Summary of the invention
In order to solve the deficiency in the above-mentioned technology, the object of the present invention is to provide a kind of radiating effect good, from heavy and light, the lifting electromagnet of hoisting ultra-high temperature steel products rational in infrastructure.
In order to solve the problems of the technologies described above, super high-temperature lifting electromagnet of the present invention for " U " shape electromagnet, comprises excitation coil, and iron core, its iron core are the crossbeam of " U " shape electromagnet, and excitation coil and solenoid housing are equipped with in the middle part of iron core; The iron core both sides are near the bottom at the solenoid housing place perpendicular stay bearing plate that respectively is connected, bottom between these two stay bearing plates is fixed with a non-magnetic radioresistance plate, and the lower surface that the iron core both sides extend through the stay bearing plate part is fixed with many flexible magnetic poles, the length of flexible magnetic pole is greater than the height of stay bearing plate, the upper end of every flexible magnetic pole is fixed, and the lower end freedom is sagging.
As a kind of improvement of the present invention, super high-temperature lifting electromagnet is " U " shape electromagnet, comprises excitation coil, and iron core, its iron core are the crossbeam of " U " shape electromagnet, and excitation coil and solenoid housing are equipped with in the middle part of iron core; The iron core both sides are connected in respectively on two iron core bases, each iron core base is fixed with a perpendicular stay bearing plate near the bottom at solenoid housing place, bottom between these two stay bearing plates is fixed with a non-magnetic radioresistance plate, the outside lower surface of each iron core base is fixed with many flexible magnetic poles, the length of flexible magnetic pole is greater than the height of stay bearing plate, the upper end of every flexible magnetic pole is fixed, and the lower end freedom is sagging.
Flexible magnetism is the magnetic conductive metal rope very.
The stay bearing plate of above-mentioned two kinds of super high-temperature lifting electromagnets is a rigid body; Or two structures that rigid body forms by bolted connection about being, be lined with one deck thermal insulation material at joint face.
The upper surface of the radioresistance plate of above-mentioned super high-temperature lifting electromagnet covers one deck thermal insulation material.And have breather port on the stay bearing plate.
Because the present invention adopts " U " shape electromagnet, and excitation coil is contained in the structure on " U " shape electromagnet crossbeam.On the one hand the non-magnetic radioresistance plate that is connected of the bottom between two stay bearing plates has a bigger space between stay bearing plate and the solenoid housing, and one deck thermal insulation material that radioresistance plate upper surface covers can effectively reduce radiation.Make excitation coil relatively away from by the high-temperature steel iron product of handling by stay bearing plate on the other hand, the bottom of stay bearing plate and the distance of iron core are bigger, generally in hundreds of millimeter, thereby the heat conduction distance is longer, on the stay bearing plate breather port is arranged in addition, good convection current air is arranged around the stay bearing plate, be beneficial to the stay bearing plate heat radiation, the heat that conducts to iron core by stay bearing plate is greatly reduced.Stay bearing plate is actual in addition is fixed magnetic pole, but for the electromagnet structure that flexible magnetic pole is arranged, its magnetic conduction mainly is flexible magnetic pole, the radical function of stay bearing plate is then for supporting electromagnet, maintenance is by the high-temperature steel iron product of handling and the relative position of solenoid housing, therefore, stay bearing plate can be divided into two joints up and down, connecting with bolt is a rigid body, and at joint face pad one deck thermal insulation material, even now stay bearing plate magnetic conduction effect meeting weakens, but the amount that weakens can be diverted on the flexible magnetic pole, overall magnetic resistance does not increase, and this thermal insulation material will further reduce the conduction of heat; Because flexible magnetism magnetic conductive metal rope very, the magnetic pole of electromagnet is to be made of a lot of such long and thin metal ropes again, thus its face area to compare to the electromagnet increase of inflexibility magnetic pole very big, thereby further improved heat-sinking capability.The result of this structure collectivity is the heat that has significantly reduced to arrive excitation coil, plays heat-insulating effect, and the more traditional super high-temperature lifting electromagnet of structure is more reasonable.
Super high-temperature lifting electromagnet of the present invention after the improvement, I﹠M is more convenient.
Super high-temperature lifting electromagnet of the present invention has improved the handling ability because radiating effect is good under same ampere-turn situation, make its weight reduction, inhales anharmonic ratio and increases, and especially has the structure of flexible magnetic pole all the more so.
