The utility model discloses simple structure, rationally distributed, the temperature regulation and control are convenient and even from top to bottom.
Description
Technical field
This utility model relates to induction coil, especially a kind of temperature adjustable load coil.
Background technology
In medium-high frequency heating system, load coil, as core component, is to be turned to spiral type by hollow copper pipe by demand, is made through insulation and reinforcing.During heating system work, induction coil produces high-strength magnetic field under alternating current effect, and workpiece produces eddy current in alternating magnetic field, and then is heated due to self-resistance.Normally used induction coil mostly is one-part form, uniformly arranges along centerline direction between each circle of spiral winding, and temperature controls mainly to be regulated by intermediate frequency power supply and capacitor.But owing to body of heater upper and lower two ends heat-insulating property is poor, cause induction coil upper and lower side temperature on the low side；Intermediate frequency power supply and capacitor are limited to induction coil input alternating current regulating power.
Utility model content
For overcoming the deficiency of the problems referred to above, it is achieved more easily regulation and control and more uniform temperature is distributed, and this utility model provides temperature adjustable load coil.
For achieving the above object, this utility model adopts the following technical scheme that a kind of temperature adjustable load coil, including multistage induction coil, described multistage induction coil from centering coil to the turn-to-turn of two end-coils away from reducing step by step, the turn-to-turn of described centering coil is away from for 60-120mm, the turn-to-turn of described two end-coils is away from for 40-60mm, and the electrode area of described multistage induction coil is provided with temperature conditioning unit, and described temperature conditioning unit is magnet ring or air core inductor.
Further, the progression of described induction coil is 2-5 level.
Further, described induction coil is 3 grades.
Further, the number of described temperature conditioning unit is 1-6.
Further, the number of described temperature conditioning unit is 3-4.
Further, the turn-to-turn of described centering coil is away from for 100mm, and the turn-to-turn of described two end-coils is away from for 50mm.
Further, the head and end face in one plane interleaved arrangement of described multistage induction coil.
This utility model has the beneficial effect that load coil is divided into multi-pole coils to form, and every grade of coil can individually control to heat up；Two end-coils lower turn-to-turn Temperature Distribution in carrying out regulating stove by increasing coil turn, are allowed to evenly；Electrode area is inserted in the magnet ring of varying number or seals in air core inductor, utilizes magnet ring or air core inductor to being passed through the damping action of alternating current intensity of induction coil at different levels and then regulating in-furnace temperature easily；The head and end face in one plane interleaved arrangement of induction coils at different levels, reduces the current field interference between coil at different levels, the more conducively installation and debugging of induction coil, increases the air-tightness of body of heater simultaneously.
