Abstract

A bar nozzle-type plasma torch according to an embodiment of the present invention comprises: a bar electrode having a support and an electrode tip connected to one end of the support; and a cylindrical body for generating plasma by means of the electrode tip being inserted into a nozzle electrode having a groove formed therein.

Description

technical field [0001] The present invention relates to a rod-shaped nozzle type plasma torch, and more particularly, to a device in which a rod-shaped body is inserted through a rear electrode and a groove is formed inside the nozzle of the front electrode. Background technique [0002] Since it was officially put into use in industrial sites in 1950, torches have been widely used in plasma incineration and melting, and the performance of torches has been continuously improved. In particular, recently, with the realization of the importance of improving energy efficiency through non-transfer-transfer dual-mode operation for high-power incinerators and melting plants, there has been a lot of research on dual-mode (DualMode) reverse polarity plasma torches. Research on application possibilities. In addition, for the activities of the anode spot and the cathode spot inside the DC plasma torch composed of the anode and the cathode, the activity of the anode spot is relatively ...
