Abstract

The invention discloses a heating device and a method for heating steel pipe circular seams by using the heating device. The heating device comprises a moving device, and temperature control equipment, a fixed bracket and a track heating plate bracket arranged on the moving device; the moving device is used for moving the whole heating device; the fixed bracket is fixed on the moving device, and is connected with the track heating plate bracket; the track heating plate bracket is provided with a track heating plate; the shape of the track heating plate bracket is matched with the diameter of a steel pipe; during working, the track heating plate bracket is bonded with the surface of the steel pipe, and the track heating plate heats the steel pipe; and the temperature control equipment is electrically connected with the track heating plate for controlling the heating temperature of the track heating plate. The heating device and the method for heating the steel pipe circular seams by using the heating device are flexible, convenient and efficient in use, and are safe and reliable.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a heating device and a method for heating steel pipe annular seams by using the heating device. Background technique [0002] With the further development of the hydropower market and the advancement of technology, the proportion of newly built high-head hydropower stations and pumped storage power stations in China is gradually increasing. This type of power station needs to use a pressure pipe formed by sequential welding of multiple penstock steel pipes for water diversion, that is, two adjacent penstock steel pipe nozzles are heated for a week, and the butt weld is called circular seam heating. [0003] The water diversion penstock is characterized by large diameter and thick pipe wall, and is mostly made of 600MPa-800MPa high-strength steel plates at home and abroad. Therefore, the welding process of water diversion penstocks is complicated. During the weld...
