Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 and Fig. 2, present embodiments providing a kind of aluminium alloy round cast ingot cartridge heater includes heating cylinder 1,
Heating coil is provided with the heating cylinder 1, the heating coil includes three sub- heating coils being independently arranged, and is respectively
First sub- heating coil 2, the second sub- 3 and the 3rd sub- heating coil 4 of heating coil, first sub- of heating coil 2, second add
3 and the 3rd sub- heating coil 4 of heat coil is respectively connected with independent controller, sub- heating coil corresponding to the controller control
Power, to control the temperature of the heating region of the sub- heating coil, along the length direction of aluminium alloy round cast ingot, each sub- heater wire
The heating-up temperature of circle is successively decreased or is incremented by successively.
The heating cylinder 1 is in being provided with glass fibre ceramics cloth 5, the glass fibre ceramics cloth in the heating coil
Stainless steel inner container 6 is provided with 5, the stainless steel inner container 6 surrounds the cavity 8 for housing aluminium alloy round cast ingot 7, the heating
The both ends of cylinder 1 are mounted on the offset plate 9 that insulate.
Several temperature measurers 10, the temperature measurer 10 and institute are arranged at intervals with the heating cylinder 1 along its length
Controller electrical connection is stated, and the temperature measurer 10 is connected to the piston rod end of lift cylinder 11, the lift cylinder 11 is set
In on the heating cylinder 1, during measurement, the lift cylinder 11 drives temperature measurer 10 to cling to the surface of aluminium alloy round cast ingot 7
Carry out temperature survey.
The heating means of above-mentioned aluminium alloy round cast ingot cartridge heater, it comprises the following steps：
1) preheat：Aluminium alloy round cast ingot first carries out cardinal temperature heating using the long rod gas-fired heater of more ingot castings, uniformly
420 DEG C of sawings of coming out of the stove are heated to, the short ingot casting, which enters, after sawing carries step rail road special cart, and ingot casting is delivered into power frequency sense by dolly
Heating furnace is answered, then ingot casting is sent into aluminium alloy round cast ingot cartridge heater by specific purpose tool；
2) gradient-heated：Heating coil 1 is made up of three independent sub- heating coils, and has three temperature controller controls, can
The short ingot casting is heated into three sections of different temperature；During according to isobaric technique extruding aluminium alloy material, put down under equal extrusion speed
Face mould tool circle ingot casting is squeezed into product, and its temperature raises 40 DEG C, and assembling die circle ingot casting is squeezed into product, its temperature rise 60
DEG C, i.e., round ingot casting temperature is 480 DEG C, and product maximum temperature is up to 505~540 DEG C, now extrusion speed 0.3 circle after squeezing
Ingot casting will be decrescence slow；It is 480 DEG C that circle ingot casting (assembling die production) the most leading portion now is set into heating-up temperature, and stage casing sets heating
Temperature be 465 DEG C, most back segment set heating-up temperature be 450 DEG C, using aluminum alloy heat conductibility it is good the characteristics of, from the gradient-heated
Good ingot casting goes out coil and starts to extrude to extruder, and the temperature at gradient is close to each other, makes three original gradients close to one
Straight oblique line, extrusion speed when being extruded using equipressure carry out constant speed extruding, and the temperature control of product is at 505~530 DEG C.For
Ensure the process implementing, the product temperature after the accurate infrared thermometer monitoring deformation of installation one at extruder outlet, one
It is whether inspection is consistent with theoretical temperatures, second, adjustment extrusion speed, makes extrusion speed be obtained most after being combined with aluminium ingot casting temperature
Good product quality, most fast extrusion speed.
During extruding, under pressure ram effect, itself starts mushrooming deformation, is drastically rubbed with recipient liner in advance,
Heat is produced, enables aluminum alloy to justify ingot casting temperature rise；Aluminium alloy round cast ingot meets mould, under high pressure effect, produces deformation, promotes
Product temperature rise after deformation, it is too high to cause product burning, Quality Down or scrap.Such as set using aluminium alloy round cast ingot temperature
Put again it is lower, can cause aluminium alloy round cast ingot starting extruding when, the product after deformation must can not be raised to minimum by caused heat
Solid melting temperatur, then extruded product is substandard product.So by the way of gradient heating, when can just extrude, lifting
When temperature is smaller, aluminium alloy round cast ingot heating herein is higher, can reach solid melting temperatur, when posterior segment lifting temperature is larger,
Aluminium alloy round cast ingot heating is relatively low, and the two is combined can reach solid melting temperatur again.Extrusion speed need not be turned down to heat up to reduce
It hurry up.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, there will be changes, this specification content should not be construed as in specific embodiments and applications
To limitation of the present utility model.
