Abstract

The effect of the axial gas flow-rate on the characteristics of torch plasma, which is a DC arc plasma produced by a transferred type torch, has been investigated. The voltage gradient of torch plasma is about 2-4V/cm. It increases with the axial gas flow-rate and decreases with the current. However, it becomes constant near a current of 200 A and an axial gas flow-rate of 4Nl/min. The central temperature of torch plasma is not affected by the axial gas flow-rate and increases with the current. The radial temperature distribution becomes flatter when the current increases and the axial gas flowrate decreases.
