Abstract
The invention relates to a slab laser cladding compound alloy layer heater which comprises a furnace body, a rolling screen orbit and a thermal insulation rolling screen cover plate. The upper ends of the two sides of the furnace body are provided with the rolling screen orbit where the thermal insulation rolling screen cover plate is arranged in; the two ends of the thermal insulation rolling screen cover plate are respectively fixed on a winding axle that is connected with a synchronous motor; and the synchronous motor is connected with a controller by a lead. A scaffolding is positioned below the thermal insulation rolling screen cover plate and a heating band connected with the controller by the lead is positioned below the scaffolding. The two ends of the furnace body are respectively provided with a thermocouple that is connected with the controller by a compensation lead. The heater satisfactorily solves the problems that two different metals are clad together, and the operation of a laser head is uniform and complete, thus leading to excellent cladding quality, small thermal loss, high efficiency, constant temperature control, low energy consumption, energy conservation, cleanliness and sanitation and no pollution. The heater is applicable to metallurgy industry and equipment manufacturing and repair industry.
Description
Technical field
What the present invention relates to is well heater, and concrete is adopts laser that the metallic substance of two kinds of different melting points is made the heating unit that gives of high-strength compound aspect, makes it to guarantee to do at a certain temperature the flat-plate laser cladding composite alloy layer heater of laser melting coating.
Background technology
Continuous development along with science and technology, the progressively expansion of emerging technology, laser industry processing constantly is dissolved in the new complete processing field, adopting new technology, in the time of novel method, original device and equipment have not satisfied the requirement to new processing object, high-strength compound layer such as metallurgy industry copper crucible surface in the continuous casting process flow process, former is to rely on import, present domestic employing coating method in the majority, this method has 2 disadvantages, and the one, the thickness of the copper metal layer of crystallizer is not accomplished to follow one's bent, and the 2nd, the intensity of crystallizer composite bed is not good enough, with the passing of time after is not " peeling ", is exactly very easily wearing and tearing.
This difficult problem of high-strength compound layer that good complete processing energy adequate solution copper crucible surface is not arranged at present as yet, develop rapidly along with laser technology, utilize the method for laser casting can conveniently solve the difficult problem of this technology, yet two kinds of different metals get up also to truly have difficulty because of the different foundings of fusing point.
Summary of the invention
The objective of the invention is at also not properly settling at present two kinds of different metals are difficult for founding because of the fusing point difference practical problems, preheat earlier and provide a kind of, workpiece utilizes laser to carry out the flat-plate laser cladding composite alloy layer heater of cladding down hot.
The technical scheme that adopts is:
Flat-plate laser cladding composite alloy layer heater comprises body of heater, roller shutter track, insulation roller shutter cover plate; The upper end of described body of heater both sides is provided with the roller shutter track, and insulation roller shutter cover plate is arranged in the roller shutter track, and the two ends of insulation roller shutter cover plate are corresponding respectively to be fixed on the winding wheel shaft at two ends.
Be provided with stand below the insulation roller shutter cover plate, be provided with the heating zone below the stand, the heating zone is connected with controller by lead.
Above-mentioned body of heater two ends are respectively arranged with thermopair, and thermopair is connected with the temperature control input end of controller by compensating lead wire.
The winding wheel shaft at above-mentioned two ends is connected with the shaft of two synchronous machines respectively, and the control end of synchronous machine is connected with controller by lead.
Working routine of the present invention:
At first body of heater is placed in the scope of activity of laser optical head, level up, connect external power, before the heated parts with the insulation roller shutter cover plate scrolling above the body of heater to an end, on stand, put the workpiece that will heat cladding, following power is that 25KW covers the belt heating piece, can do dynamic adjustment with the geometrical shape of workpiece, to be incubated the upper surface of the whole topped bodies of heater of roller shutter cover plate by controller, set working temperature, send electrically heated, for making the cladding better effects if, in the process of heating, thermopair is input to controller with the temperature signal that detects, and determines 2-3 to add thermal gradient in advance by the program of moving, promptly be heated to constant temperature for some time after the certain temperature, continue heating again, constant temperature is after being heated to specified temperature again, and at this moment laser head from one end to the other side moves the whole process of carrying out laser melting coating in the laser work district of insulation roller shutter cover plate.
The solution that the present invention is highly desirable this long-term insoluble difficult problem of two kinds of different metal cladding one, the two kinds of different metal desires of fusing point thermal conductivity that reach that " duration and degree of heating " of heating is just right melt states to be melted, automatically control the whole process of laser head cladding again by controller, very even, comprehensive because of laser head operation, the quality of cladding quite can be good, body of heater has insulation, and insulation roller shutter cover plate is arranged above, and insulation roller shutter cover plate can directly be followed the tracks of laser head and moves.Whole cladding process calorific loss is quite little, and it is complete to add the Controlling System performance, efficient height of the present invention, and the constant temperature regulation and control, it is little to consume energy, save energy, sanitation and hygiene are without any pollution.
