产生等离子体的装置，通常叫作等离子枪，有电弧等离子枪和高频感应等离子枪两类。
The working gas is passed
into the plasma gun, which has a device that generates an arc or a
high-frequency (5 ~ 20 MHZ) electric field, and the working gas is
ionized after being acted on, resulting in a plasma composed of
electrons, positive ions and a mixture of gas atoms and molecules.
把工作气体通入等离子枪中，枪中有产生电弧或高频（5～20兆赫）电场的装置，工作气体受作用后电离，生成由电子、正离子以及气体原子和分子混合组成的等离子体。
After
the plasma is ejected from the nozzle of the plasma gun, the high speed
and high temperature plasma arc flame is formed, and the temperature is
much higher than that of the general arc.
等离子体从等离子枪喷口喷出后，形成高速高温的等离子弧焰，温度比一般电弧高得多。
Commonly used working gas is argon, it is a single atomic gas, easy to ionize, and is an inert gas, can protect the material.
常用的工作气体是氩，它是单原子气体，容易电离，而且是惰性气体，可以保护物料。
Operating temperature up to 20000□;
工作温度可高达20000□；
Used for smelting special steel, titanium and titanium alloys, superconducting materials, etc.
用于熔炼特殊钢、钛和钛合金、超导材料等。
The
furnace types are equipped with water-cooled copper mold furnace,
hollow cathode furnace, plasma furnace equipped with induction heating,
plasma furnace with refractory lining, etc.
