摘要： PURPOSE: To provide a bending method for a metal tube in which a bent metal tube is measured/corrected for the difference between a bent angle and a desired bent angle on a bending device and correction is not required after a tube is dismounted from a bending device. CONSTITUTION: A metal tube 1 to be bent is passed a suitable heating device to locally heat in an annular shape and its working tip side is clamped 4A to an rotatable arm 4, while heating the metal tube 1 by a heating device, a heating part 2 is traveled in the longitudinal direction of the tube with a suitable traveling device, immediately after bending moment is imparted for deformation, the heated part 2 is cooled with a suitable cooling means. As soon as a bent angle is reached to a set value, the deflection between the metal tube 1 and a bending moment imparting device is released to the counter working side, the deviation between the set angle and bent angle of the tube is detected, the tube is again traveled up to the angle with the deviated angle added to the set angle to the working side or the counter working side and the bent angle is corrected.

摘要： PURPOSE: To improve reliability of a joined part by welding between tube ends by means of a liquid phase diffusion welding method and also causing thickening with hardly increasing the inner diameter of the joined part. CONSTITUTION: Both tube ends 1 are abutted on each other through an insert material 3, an induction heating coil 5 is arranged around the abutting part 2, and the tube ends are heated rapidly in a narrow annular shape so as to raise the temperature to join them. In the middle of raising temperature and after the part becomes red hot state, a large compression force in the tube axis direction is added for a short time under a steep temperature distribution with the abutting part as a center. As a result, a compressed deformation is caused only in the narrow area of the abutting part 2, thereby causing the thickening with hardly increasing the inner diameter, with increasing only the outer diameter and without a flaring tendency. In addition, before and after the compression operation, a stress-regulating pressurizing is carried out in the direction of the tube axis, thereby maintaining the closely joined state between the tube ends.

摘要： PURPOSE:To prevent the abnormal local heating and carry out uniform heating in the microwave heating of a solid raw material to be subjected to chemical reaction. CONSTITUTION:A solid raw material is formed to almost spherical shape. The obtained spherical raw material 6 is transferred under rotation with a transfer apparatus 5 and irradiated with microwave with a microwave waveguide 4 during transfer. Since the solid raw material is formed to almost spherical shape, edges to concentrate the microwave energy are eliminated to prevent the abnormal heating caused by the microwave concentration. Furthermore, uniform microwave heating can be carried out by the rotation of the spherical raw material to prevent the concentration of microwave caused by temperature difference.
