Abstract
The invention relates to a steel water-cooled magnetic lifting skirt plate on a bar cooling bed. The plate is mainly characterized in that an excitation coil is arranged in the lifting skirt plate, and an appropriate magnetic circuit is formed by a magnetic conduction material, thereby enabling the working face of the skirt plate to generate a magnetic field to firmly adsorb a steel material and accurately and quickly moving the steel material along with the lifting skirt plate. Simultaneously, a circulating cooling water passage is further arranged between a combined magnetic pole and the excitation coil, thereby not only reducing the temperature of the working face of the skirt plate, but also taking away heat generated by the coil. The steel water-cooled magnetic lifting skirt plate can avoid the phenomenon of meshing up the bed when conveying bars, greatly improving the steel rolling speed and also reducing the consumption of spare parts.
Description
Technical field
The present invention relates to the mechanical equipment of steel rolling field, be specially a kind of bar material cooling bed steel-feeding water-cooled magnetic force lifting skirtboard.
Background technology
Existing bar material cooling bed steel-feeding lifting skirtboard is nonmagnetic lifting skirtboard, because the rolled piece bar is longer, have than macrobending, thereby can not finely contact with the lifting skirtboard, so can not produce enough friction with the lifting skirtboard, thereby the lifting skirtboard can not well brake bar with lifting skirtboard motion, turns over the steel purpose and reach.Have a strong impact on production efficiency like this.Not having magnetic lifting skirtboard Facing material simultaneously is cast steel, and not through Overheating Treatment, hardness and wearing no resistance, and not wear-resisting, producing needs to consume a large amount of spare parts, and need spend a lot of times to change, and so not only spare part expense height also has a strong impact on production efficiency.
Summary of the invention
The object of the present invention is to provide a kind of bar material cooling bed steel-feeding water-cooled magnetic force lifting skirtboard.The magnetic force of its generation can guarantee that bar and lifting skirtboard produce enough friction braking bar motions, thereby can greatly enhance productivity.The skirtboard of water-cooled magnetic force lifting simultaneously surface is that high abrasion resisting material is made, and abrasive resistance improves a lot, thereby can reduce and change number of times to save time, and also reduces spare parts consumption simultaneously.
Technical scheme of the present invention is: a kind of bar material cooling bed steel-feeding water-cooled magnetic force lifting skirtboard, and mainly by the lifting support plate, the protection base plate, side plate, iron core, magnet exciting coil, electrical source importing device, composite poles is formed, and it is characterized in that: the top of lifting support plate is a composite poles; Be provided with iron core and magnet exciting coil below composite poles, magnet exciting coil is wrapped on the iron core, and is connected with electrical source importing device; On the composite poles of iron core and magnet exciting coil front-back, be provided with side plate; Below iron core and magnet exciting coil, be provided with the protection base plate; The both sides of iron core and magnet exciting coil and above be provided with cooling water channel; Cooling water channel is provided with water inlet and delivery port, and the circuit of described cooling water channel and magnet exciting coil separates.
The present invention is when work, and the magnet exciting coil energising back that is wrapped on the iron core produces magnetic field, and iron core, composite poles and side plate are formed magnetic circuit, and its lifting skirtboard working face sucks steel and makes its accurate fast braking because of being magnetic.In addition because the circuit of cooling water channel and magnet exciting coil separate, cooling water with ordinary tap water just can, and the difficult damage equipment that leaks electricity is handled in insulation easily.Cooling water in the cooling water channel can stop the steel heat that passes through from magnetic pole strength to conduct the heat that can take away the coil working generation to coil again, and coil temperature can not raise.Simultaneously cooling water also can cool off magnetic pole, is adsorbed thereby make to descend to becoming to be magnetic fast from the nonmagnetic steel temperature of its high temperature that passes through.
Further aspect of the present invention is: described composite poles is superimposed with each other by thick magnetic conduction magnetic pole of polylith and polylith leptophragmata magnetic magnetic pole and forms.
Because composite poles is by thick magnetic conduction magnetic pole of polylith and thin being formed by stacking every the magnetic magnetic pole of polylith, thereby the magnetic pole pole span is short, so magnetic line of force penetration depth is shallow, thereby can make magnetic pole strength magnetic force even, its magnetic field can not influence the miscellaneous equipment operate as normal.
The material of composite poles of the present invention is a magnetic conduction manganese steel, and its working surface is handled through over carburizing nitrogen, thereby wearability is good, can reduce spare parts consumption.
The present invention be directed to original use does not have magnetic lifting skirtboard and can not quick and precisely not brake steel because of there being magnetic, causes random bed, and the difficult problem that steel rolling speed can not be improved draws through earnest analytical study.The lifting skirtboard is nonmagnetic, steel friction on skirtboard is not enough, the lifting skirtboard can not quick and precisely be braked steel, thereby can not satisfy the requirement of high speed steel rolling, therefore take following mode to improve: the one, a magnet exciting coil is set in the lifting skirtboard, form suitable magnetic circuit with permeability magnetic material, make it produce magnetic field on lifting skirtboard working face and suck steel, steel just can be by the accurate fast braking of lifting skirtboard like this.The 2nd, can produce heat energy when working because of magnet exciting coil, the steel of high speed steel rolling simultaneously temperature is very high and coil itself can not bear high temperature, therefore design has a cooling water circulation canal, both can stop of the influence of steel high temperature from its cooling water that passes through to coil, the heat energy that coil itself produces can be taken away again, to guarantee the coil life-span.Its steel temperature of high speed steel rolling simultaneously is very high, and its temperature has surpassed residence reason temperature and do not had magnetic.And the cooling water in the cooling water circulation canal can cool off lifting skirtboard working face, thereby is sucked when steel descend to becoming to be magnetic by temperature in the above fast.The 3rd, working face is thick magnetic conduction magnetic pole of polylith and thin being formed by stacking every the magnetic magnetic pole of polylith, and the magnetic pole pole span is short, so magnetic line of force penetration depth is shallow, thereby can make magnetic pole strength magnetic force even, and magnetic force does not have adverse effect to neighbouring device.
The present invention has following advantage:
1, can not cause random bed in the time of bar being carried;
2, steel rolling speed is increased substantially;
3, can reduce spare parts consumption.
