Study on the Improvement of Turning Technology for Ring Groove of Flame Tube of Heavy Gas Turbine

Abstract

This paper takes the flame tube of heavy duty gas turbine with a specific wall thickness of 4.78mm conical cylinder as the researching object, combining with the structure characteristic and material characteristic of the flame tube, carries on the technological analysis to the annular groove turning of the heavy duty gas wheel flame tube. According to the actual working conditions, the machining method of annular grooves in turning is improved, so that the processing cost of annular grooves in flame tubes is greatly reduced, which can be used for reference in actual production.
