Abstract

This article mainly discusses a program suitable for calculating the radiative coefficient of various steam turbine rotors with matlab.Both the transient temperature and thermal stress fields of domestic 600MW supercritical steam turbine rotors under cold IP cylinder start-up were calculated with the finite element software（marc）.Finally

according to calculation and analysis

some suggestions for safe operation of domestic 600MW supercritical steam turbine were proposed.
