Description
Technical field
The utility model relates to a kind of lifting electromagnet, especially relates to a kind of lifting electromagnet of handling high-temperature vertical steel roll.
Background technology
Often need the coiled sheet under the handling condition of high temperature during coiled sheet is produced, as the vertical steel roll (being the roll of steel plate of axis normal in horizontal surface) of handling annealed condition, the temperature of these products is generally between 100 ℃-500 ℃.The vertical steel roll of handling cold conditions generally adopts quincunx electromagnet and other multipolar electromagnetic iron now, substantially can meet the demands, but because specific temperature field and the magnetic circuit characteristics of coiled sheet under the condition of high temperature, make the heat insulation and dissipation problem of these electromagnet be difficult to solve, so increasing a bit on normally original handling cold conditions vertical steel roll electromagnet is heat insulation means, as add one deck asbestos in coil bottom, the main coil problem that heats up rapidly when still solving high-temperature vertical steel roll by the increase a.t. is to satisfy the needs of handling; Thereby make the energy consumption of electromagnet very big, and deadweight is bigger.
The utility model content
In order to solve the deficiency in the above-mentioned technology, the purpose of this utility model is to provide a kind of energy consumption low and from the lifting electromagnet of the upright volume of handling of heavy and light.
In order to solve the problems of the technologies described above, the coil of the utility model electromagnet for lifting high-temperature vertical steel roll and number of magnetic poles are even number, and the polarity of adjacent two magnetic poles is opposite, two magnetic poles be " U " type electromagnet, four and above magnetic pole be " quincunx " electromagnet; The inside bottom surface of the magnetic pole of electromagnet for lifting high-temperature vertical steel roll is fixed with a perpendicular stay bearing plate, all the other bottom surfaces of magnetic pole evenly are fixed with many flexible magnetic poles, the upper end of every flexible magnetic pole is fixed, and the lower end freedom is sagging, and the length of flexible magnetic pole is greater than the height of stay bearing plate.
When electromagnet for lifting high-temperature vertical steel roll contacts with the maximum specification vertical steel roll between two parties, distance between the flexible magnetic pole of the outermost that is connected on two relative magnetic poles is equal to or greater than the overall diameter of vertical steel roll, and the distance between cooresponding two stay bearing plate inboards is less than the diameter of vertical steel roll endoporus.The flexible magnetic pole of all that are connected on each magnetic pole equates that with the cross-sectional area of its iron core flexible magnetic pole is in the magnetic saturation state with cross-sectional area with the magnetic pole upper backup pad.Each the circle coil of strip that has guaranteed vertical steel roll can both be magnetized.
In order to increase radiating effect of the present utility model, and strengthen heat conducting distance, the height that makes stay bearing plate is greater than 100mm.
Flexible magnetism of the present utility model is the magnetic conductive metal rope very.
The utility model adopts flexible magnetism and higher supporting plate structure, on the one hand since the height of stay bearing plate greater than 100mm, high-temperature vertical steel roll is longer apart from electromagnet housing during handling, heat conducting distance is bigger, and between high-temperature vertical steel roll and magnetic pole, have than large space, airiness is good, flexible magnetism is the many magnetic conductive metal ropes of carefully growing on the other hand, thereby increased the face area of magnetic pole, help heat radiation, flexible magnetic energy contacts with high-temperature vertical steel roll well simultaneously, makes each circle coil of strip of whole high-temperature vertical steel roll all be in the magnetic conduction state.Coil consequently of the present utility model heats up very slow and limited, has solved coil intensification problem well, under same a.t. situation, the handling ability greatly improves, thereby reduced energy consumption, and because coil reduces to make the weight reduction of electromagnet, but also have the characteristics of reliable operation.
