ELECTROTECHNICAL INSTALLATION FOR HIGHFREQUENCY INDUCTION HEATING
Purpose of the development:
The installations serve for induction heating of metal products (hot extrusion; disassembly of pressed parts and running gear units of rolling stock in railway, subway, trams; assembly and disassembly of shrink fits; heat treatment of metal-composite materials and so on. Besides that, the installations are intended for forming the structure of composite alloys with the specified physical and mechanical properties and operation characteristics (e.g. for manufacture of silentblocks for diesel and electric locomotives with long lifetime). Also the installations can be used for some technological operations such as hardening, tempering, normalization, preheating at hammering, metal welding and melting.
Technical characteristic:
Òechnical specifications:
Power line……………………………… ~ 50Hz, 3 õ 380V;
Output power ………………………….. 10…150 kW;
Frequency of current in inductor……… 0.5…50 kHz;
Mean specific heating rate…………….. 30°Ñ/kg·sec.
Advantages over analogues:
The installation provides:
2–3 times reduced power consumption as compared to induction installations with heating at commercial frequency; higher efficiency of technological process owing to 3 times (on average) increased heating rate; improved sanitary-and-hygienic and ecological working conditions.
The development stage readiness:
Introduced in production
Description of the development:
()
The installation contains high-frequency inverter, set of inductors with various configurations and has installed capacity. The principle of adaptive control is used for providing the invariance of heating factors (heating rate, thermal and electric efficiency) with respect to supply line and load (inductor is the heated unit). This gives a possibility to realize heating with maximum efficiency during all technological process as well as to use wide nomenclature of inductors for heating of the parts and units that have different dimensions, mass, configurations (driving gear and clutch flange in reducer of electric locomotive, earth ring, wheel tread, ring of support bearing) and without additional adjustment of control system.
