Adopt ceramic nozzle can be the nozzle, that is set to zero height vent end direct contact with the surface is cut, can achieve very good result.
采用陶瓷外喷嘴可以将喷嘴高度设为零,即喷口端面直接接触被切割表面,可以获得很好的效果。
Results showed that the temperature, temperature gradient and thermal stress at the exit surfaces of the CWS ceramic nozzle were higher than that of other part of the nozzle.
