Problems solved by technology
Although this method has the advantages of high heating efficiency, energy saving and environmental protection, and small distortion, it has the following disadvantages and shortcomings: when the weld is heated, only the weld temperature is used as a single control target, the control method is relatively rough, and how to control the heating process The problem of achieving more precise control to improve the quality of weld heat treatment has not yet been resolved. At the same time, one more sensor is used to heat the weld. The temperature gradient in the non-heat treatment area around the weld is relatively large, and it is easy to cause large thermal stress during the heating process. Cracks appear

The present invention takes temperature and thermal stress as control objects, uses the main coil to heat the welding seam, and uses the auxiliary coil device to adjust the temperature gradient in other areas of the welding seam, so as to improve the heat treatment quality of the welded seam of the steel plate to be treated.
Description
technical field [0001] The invention belongs to the technical field of steel plate production, and in particular relates to a heating device and a method for heat treatment of a steel plate weld. Background technique [0002] As a common metal connection method, welding is widely used in the field of steel plate production. However, due to the high temperature during welding and the uneven temperature around the weld, the residual stress at the weld is large, and it is easy to appear inside the weld. Small cracks and hard spots. In order to improve the reliability of the weld, researchers mostly use normalizing and high temperature tempering to heat the weld. [0003] At present, in order to obtain better heat treatment quality of weld seam, researchers have proposed a method of heat treatment of weld seam using electromagnetic induction heating. Although this method has the advantages of high heating efficiency, energy saving and environmental protection, and small distor...
