The utility model is characterized in that an excitation coil of the main body part uses a popularity of annular thin wires to be respectively sealed singly, and filler with better thermal conduction is poured in the coils; cooling air ducts are arranged between each coil. The utility model has compact structure, the excitation coil uses full sealed structure which can effectively prevent the coil from the corrosion of powder dust, moist, harmful air, etc., and the utility model can increase the service life of products and the adaptability for adapting to severe environment. Because the whole excitation coil is designed into a popularity of annular thin coils, the utility model has big heat dissipation areas, low temperature rise and less thermal state current decline, the magnetic potential of the utility model during thermal state is increased, and the weight sucking capability of the utility model is enhanced.
Description
One, technical field:
The utility model relates to a kind of new type of compression air cooling high temperature lifting electromagnet, belongs to national patent classification B03C1/00.
Two, background technology:
The high temperature lifting electromagnet: usually said high temperature lifting electromagnet is meant the electromagnet of temperature between 200 ℃-600 ℃ of absorbate.Traditional high temperature lifting electromagnet can satisfy the operating needs of said temperature section basically.China is since the mid-90 in 20th century, because the widespread use of continuous casting technology, each iron and steel enterprise generally carries out energy-saving and cost-reducing, improve output, thereby the mill speed of steel is more and more higher, and the heat of slab, square billet send temperature more and more higher.The steel surface temperature has reached about 680 ℃, and we generally call the extra-high-speed temperature to this temperature, like this high temperature lifting electromagnet has been proposed the requirement of a harshness, and traditional high temperature electromagnet can't satisfy such operating needs.Extra-high-speed temperature lifting electromagnet should have good heat insulation, radiating condition.
High temperature lifting electromagnet heat insulation: make a general survey of the provision for thermal insulation of domestic and international high temperature lifting electromagnet, generally adopt following two kinds: 1. double-deck air is heat insulation, with air as heat insulation medium; 2. double-deck heat insulating material formed heat insulation: with warm materials such as aluminium silicate, rock wools as heat insulation medium.More than two kinds of measures can isolate high temperature billet steel to thermal radiation and heat convection that electromagnet brought.Second kind of measure cost is higher, and effect is better than first kind.
Cooling:
The type of cooling of high temperature lifting electromagnet is divided into several:
1, natural cooling: utilize the convection current of natural air, the ironing surface heat of electromagnetism is taken away, reach the purpose of cooling electromagnet, the advantage of this method is that technology is simple, and cost is lower.Shortcoming: cooling performance is relatively poor.The conventional high-temperature lifting electromagnet adopts this to use the method more.
2, water-cooled: utilize tap water that magnet coil is cooled off.The advantage of this method is a good cooling results.Shortcoming is the water route that needs special closed loop, and pipeline also need carry out the conversion of straight-line motion and curvilinear motion, the pipeline complexity, and the manufacturing process complexity of electromagnet, the manufacturing cost height, this method does not generally adopt now.
The cooling of 3 pressurized airs: utilize the lower pressurized air of temperature that magnet coil is cooled off, the advantage of this method is that cooling performance is better, and the electromagnet manufacturing process is simple than water-cooled, can adopt the open loop wind path, and pipeline is simpler.Shortcoming is to need air compression station air feed or special air pump air feed.
4 blower fans cooling: blower fan is installed on electromagnet, the electromagnet surface is cooled off.The advantage of this method: install simply, cost is low.Shortcoming: need take very large space, in addition, blower fan is easy to break, the maintenance cost height, because the ambient temperature height, cooling performance is relatively poor.Thereby this method seldom adopts in lifting electromagnet.
The hermetically sealed natural cooling type high temperature lifting electromagnet of my company's original production is the technology of introducing from Japanese Sinkoudenki K. K; its feature is with the excitation coil sealing in the enclosure; utilize special processing technology; protect excitation coil not to be subjected to the erosion of dust and moist pernicious gas effectively; but coil temperature rise height; hot electric current descends more, and extra-high-speed temperature occasion is difficult to meet the demands.
Three, summary of the invention:
The purpose of this utility model is to solve the existing hermetically sealed high problem of natural cooling type high temperature lifting electromagnet coil temperature rise and a kind of new type of compression air cooling of design-calculated high temperature lifting electromagnet.
The technical solution of the utility model is: it is made up of body part, tracheae reel, air pump, rectifier cabinet, it is characterized in that: the excitation coil of body part adopts the sealing separately respectively of the thin coil of a plurality of annulars, irritate with the good weighting material of heat conductivility in the coil, be provided with cooling air channel between each coil.
Excitation coil of the present utility model adopts the sealing separately respectively of the thin coil of 1～3 annular.
Weighting material in the excitation coil of the present utility model is special insulating material.
The utility model has a plurality of air-out windows on the shell of body part, form cooling air channel jointly.
The utility model compact conformation, magnetic Circuit Design is reasonable, and excitation coil adopts all-sealed structure, can prevent the erosion of pernicious gases such as dust, humidity to coil effectively, can improve the service life of product greatly and to the comformability of harsh environment; Whole excitation coil is designed to the thin coil of a plurality of annulars, the heat of hub of a spool part is come out easily, the dissipating area of coil is upper and lower surface and side on the other hand, so the dissipating area of a plurality of thin coils is far longer than single single-piece dissipating area, thereby temperature rise is low, hot electric current descends few, just makes that the magnetic potential when hot increases, and has improved suction Beijing South Maxpower Technology Co. Ltd power.
