空气电弧吹割法,就是当炭精棒与钢板之间产生电弧的同时,从炭精棒围周吹出的压缩空气将熔化的铁水吹去,形成一条平直的割缝。这种方法所需设备非常简单,一台普通直流电焊机(电压30伏特,电流320安培),一台能保持6～7公斤/厘米~2压力的风泵和一把切割枪,即可进行切割。切割枪 Air arc blowing method, that is, when the arc between the carbon rod and the steel plate at the same time, from the circumference of the carbon rod blown compressed air blown molten molten iron to form a straight cut. The equipment required for this method is very simple, an ordinary DC welder (voltage 30 volts, current 320 amps), a wind pump capable of maintaining a pressure of 6 to 7 kg / cm 2 and a cutting torch can be used Cutting.
