High-frequency induction plasma system PLAZER HF 60/5,28
In the high-frequency plasma equipment manufactured under the trademark PLAZER® the generator is the source of high-frequency (HF) discharge, which install a powerful electromagnetic field of high frequency leads in the inductor of the system. The equipment has been manufactured with an operating frequency of 1.76 or 5.28 MHz depending on the technological tasks.
High-frequency plasma system PLAZER HF 60/5,28 was developed on the basis of valve oscillator with oscillatory frequency 5,28 MHz andoutput capacity 60 kW.
The system can be supplied in several versions for its configuration into various technological systems and implementation of the following technological tasks:
- production of charging material in the ingots melting pot , including refractory oxides, without limitation of feedstock melting temperature;
- production of chemically pure low-temperature plasma used in the processing of disperse materials (spheroidization) refractory materials and metals, nanomaterials synthesis);
- induction-plasma spraying
- plasma hardening and induction surfacing;
- production of monocrystals;
- production of carbon nanotubes, fullerenes

Control of the refractory materials (oxides) melting process and their processing usingHF plasma equipment PLAZER ® is carried out by the operator as in manual as in fully automatic mode underthe given program.The program is integrated into industrial computer (PLC) of the process parameters.The monitor displaysdata of the current process with the possibility of their corrections (frequency, temperature of the cooling liquid (water), current, voltage, etc.).The process of the ingot formation is carried out by way of natural cooling and subsequent solidification of the melt.Controller interface and the name of control bodies — in Russian. Convenient for the operator load / unload of material is provided. Access to all units of the system is carried out smoothly for their maintenance. For safe operation the process gases withdrawal, generated during melting process, is provided.
