ELECTROMAGNETIC AND GAS DYNAMIC CONTROL OF TRANSFERRED PLASMA ARC IN METALLURGICAL PLASMA REACTORS AND FURNACES
Краткое описание
One of the advantages of plasma metallurgical technologies is the possibility for effective processing of powdered raw materials and waste. This avoids preliminary agglomeration (pelletization) which is a standard, expensive and non ecological process in the classic extractive metallurgy.
The main unit of metallurgical plasma equipment is the system Plasma torch − Plasma reactor (plasma furnace). The limit stage determining velocity and completeness of chemical processes is the heating rate and melting of powdered charge which depends mainly on plasma arc organization.
In extractive metallurgy plasma equipment preliminary uses DC transferred plasma arcs.
The existing laboratory, pilot and industrial methods for electro magnetic and gas dynamic control of DC transferred plasma arc, aiming to obtain maximum heat exchange between it and the processing charge are described in this work.
The original PLASMALAB system for Auto-Electro-Magnetic Rotation (AEMR) of DC transferred plasma arc in the system Plasma torch with hollow graphite cathode − FFP- reactor (anode) is also described.
