Medium Frequency 80KW Fast Start-up Induction Heat Treatment Machine For Shrink Fitting
INDUCTION SHRINK FITTING
Shrink fitting involves the preheating of a metal component for the insertion of another metal component producing a strong mechanical joint between two pieces of metal. As heat is applied to one component it expands while the component to be inserted is at ambient temperature. The ambient component is inserted into the heated component and as the heated component cools down it produces a strong joint between the two components.

ADVANTAGES OF INDUCTION HEATING MACHINE:
1. Fast heating: the minimum rate of heating is less than 1 second (rate of heating is available for adjustment and control).
2. Wide coverage of heating: it can be used to heat various metal parts (replace removable induction coil as per different operating switches).
3. Easy installation: it can be used once it is connected with power source, induction coil as well as water supply pipe and rising pipe; it is small in size and light in weight.
4. Easy operation: you can learn to operate it within several minutes.
5. Fast start-up: it can be started to perform heating operation on condition that water and power supply is available.
6. Low power consumption: As compared with conventional vacuum tube high frequency equipments, it can save the power by approximately 70%. The smaller the size of the work piece is, the lower power consumption would be.
7. High effectiveness: it has such features as uniform heating (it is applicable to adjust the spacing of the induction coil to ensure the appropriate temperature as required by each part of work piece), fast warming and limited oxic horizon, and can guard against any waste after annealing.
8. Comprehensive protection: it has such functions as overpressure, over-current, overheat and water shortage alarm indications as well as automatic control and protection.
9. Controllable temperature: it is applicable to control the temperature for heating work pieces as per the preset heating time, and thereby control the heating temperature at a certain technical point.
10. Comprehensive full load design: it can work continuously for 24 hours.
11. Small size and light weight: it has a weight of only several dozens of kilograms, of which, the limited floor space can effectively save the workshop space.
12. Elimination of high voltage: it requires no step-up transformer which may produce approximately ten thousand voltage, and thus can ensure the maximum safety.
