The heating device comprises a heating jacket covered with magnetic steel; the heating sleeve is directly mounted on a magnetic pole-orienting clamp and consists of heat-resistant non-magnetizers sleeved inside and outside; a high temperature-resisting resistance insulating material is stuffed in a sleeve interlayer; and a heating element is embedded into the insulating material and is electrically connected with a constant temperature control device used for regulating the power of the heating sleeve and stabilizing the temperature through a sensor, a temperature controller and a voltage regulator. The heating sleeve is adopted for heating elements to convert electric energy into heat energy; the voltage is changed through the voltage regulator to realize different powers; the constant temperature control device is used for maintaining the temperature required by the heating sleeve; therefore, the problems that the time is long, the temperature falls rapidly, the heat loss is serious, and the magnetic pole orientation of the magnetic steel is hard to be constant in the magnetic pole orienting process of the magnetic steel are solved.
Description
Technical field
The utility model relates to a kind of high-temperature heating equipment of automatic constant-temperature magnet steel magnetic pole orientation.
Background technology
Magnet steel is the general name of magnetic alloy, is modern most important permanent magnetic material.It has good magnetic, in mechanotronics, is widely used.Magnet steel commonly used has two kinds of Al-Ni-Co5 and Al-Ni-Co8, is commonly referred to as five types of magnet steel and eight types of magnet steel.Its most original definition promptly is alnico alloy (magnet steel AlNiCo in English is the abbreviation of aluminium nickel cobalt), is called natural magnet by people.At present, to the magnetization method of magnet steel, be magnet steel to be put into high temperature furnace be heated to 750-800 ℃ in the prior art, then magnet steel is taken out, be surrounded with insulation material, be placed on the magnet charger and magnetize.In this process, all to require the magnet steel magnetic pole orientation in the process of magnetizing constant usually.Yet in this process, it is very fast that the magnet steel temperature descends, and thermal loss is serious, and the magnetic pole orientation of magnet steel is difficult to the requirement that reaches constant, and neither directly perceived in the operation, inconvenient again, controls difficult assurance.And the fusing kirsite heating collar non-refractory that prior art is used, can only continuous operation 24 hours, useful life is lower.
Summary of the invention
The utility model purpose provides a kind of easy and simple to handle, intuitive display, high temperature resistant, the heater that can keep temperature constant when being to the magnet steel magnetic pole orientation.
The utility model solves the technical scheme that its technical problem adopted: a kind of heater of automatic constant-temperature magnet steel magnetic pole orientation; Comprise a heating collar that coats magnet steel; It is characterized in that; Said heating collar is directly installed on the magnetic pole orientation anchor clamps, and this heating collar is made up of the heat-resisting rigidity non-magnetizer of inside and outside cover, and the cover interlayer is filled with high temperature resistant resistance property insulating material; Heater element is embedded in the insulating material, and is electrically connected a thermostatically-controlled equipment of regulating above-mentioned heating collar power and steady temperature through transducer and temperature controller, voltage regulator.
The utility model has following beneficial effect than prior art.
The utility model utilizes the higher insulating material of the high temperature resistant resistance property of heating collar filling and is embedded in heater element resistance wire in the insulating material, converts electrical energy into heat energy, changes voltage through transducer and temperature controller, voltage regulator, realizes different capacity control temperature.The high temperature that heat good insulating, life-span be long, high temperature resistant, can anti-700-1000 ℃, but continuous operations did not damage in 36 hours.Heating collar can be directly installed on the magnetic pole orientation anchor clamps, realizes magnetic pole orientation in the magnet steel constant temperature, and more simple, the intuitive display, the fail safe that make that operation becomes are good.Solved in the magnet steel magnetic pole orientation process, temperature descends fast, and thermal loss is serious, the problem that magnetic pole orientation is difficult constant.
The heating collar that the 1Cr18Ni9Ti exotic material that adopts is processed, than more high temperature resistant, the long service life of heating collar that the fusing kirsite is processed, cost is low.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing and embodiment, but therefore the utility model is not limited among the described scope of embodiments.
Fig. 1 is the organigram of the utility model heater.
Fig. 2 is the structural principle sketch map of the utility model.
Embodiment
In Fig. 1, a most preferred embodiment of the heater that comprises heating collar, transducer, voltage regulator and temperature controller composition the utility model automatic constant-temperature magnet steel magnetic pole orientation has been described.
Heating collar is directly installed on the magnetic pole orientation anchor clamps.Heating collar internal layer 5, overcoat 6 are processed by heat-resisting rigidity non-magnetizer.Heating collar internal layer, outer field non-magnetizer can be selected heat-resistance stainless steel 1Cr18Ni9Ti for use.At the cover interlayer filled high-temperature resistive insulating material 2 of heating collar, heater element resistance wire 1 is embedded in the insulating material 2.Thermocouple 7 uses as transducer and transmits data, is placed in the heating collar.The two ends of heating collar connect mica sheet 3 and jointing, and by seal cover 4 encapsulation.The thermocouple of heater element resistance wire through being electrically connected is it is said that give temperature controller with stability number.Temperature controller is through the power of voltage regulator adjusting heating collar, the temperature of constant heating collar.Voltage regulator changes the power of voltage-regulation heating collar, thereby controls temperature required according to power P=UI formula.
In Fig. 2, have the thermostatically-controlled equipment of display, form by the relay, voltage regulator and the electric-connection thermal galvanic couple that are electrically connected heating collar and the temperature controller that has a light-emitting diode display.The temperature controller of electric connection of power supply is controlled the break-make of heating collar by the break-make of the parameter control solid state relay of setting.Thermocouple uses as transducer, is installed in the heating collar, through the temperature controller control circuit temperature data feedback is passed to temperature controller.Temperature controller is regulated the power output that voltage regulator changes power supply through the break-make of relay being controlled the heating of heating collar, but the power output of Balance Control heating collar thermal resistance.The power that changes the voltage-regulation heating collar reaches temperature required, steady temperature and insulation.The LED display that is electrically connected temperature controller shows, and the constant temperature value and the actual temperature of setting is shown through the display circuit of temperature controller.Display circuit comprises compositions such as LED charactron, alarm lamp.
