Abstract

PURPOSE:To measure an amount of bending produced due to a heating temperature and under a state at an operating time of a turbine, by a method wherein a heating is conducted in a manner to divide a rotor blank material in an axial direction and into a plural number of sections. CONSTITUTION:A rotor blank material 1 is supported at retaining stands 3 through bearing parts 2, and only a drum portion is placed at the inside of a heating furnace 40. Partitions 41 partition the heating furnace 40 such that a heating chamber 42 is situated in the middle, heating chambers 43, 45 are positioned at one side of the heating chamber 42 and heating chambers 44, 46 are located at the other side, and thermocouples are individually mounted in the heating chambers 42-46. Balancing rods 5 are installed at the inside of the heating chambers at bearing parts 2 at the opposite ends of the rotor blank material 1. One end thereof contacts with a bend bearing part, a middle part thereof is supported at a fulcrum, and the other end contacts with a dial indicator. The rotor blank material 1 is turned as it is individually heated in the heating chambers 42-46 in the heating furnace 40 in a manner to sectionally change a temperature. Each balancing rod 5 detects a bending amount at measuring points set at intervals 90 deg. on the circumference at a part where the bending of the rotor blank material 1 is measured, and the amount is measured by means of a dial gauge indicator.
