Description

Technical Field

[0001] The utility model relates to a heating device, in particular to a steel plate weld heating device. Background Art

[0002] For a continuous pickling production line, the weld welding quality is a crucial link. Especially for high-carbon martensite, post-welding tempering is required to remove welding stress to ensure the weld quality and the stable operation of the production line.

[0003] In the existing weld heating device, the heating rate is uneven, and the heating temperature and time cannot be effectively controlled, which easily leads to the appearance of unstable tissue phases, thereby affecting the mechanical properties of the weld. Secondly, as the TV value of modern production lines is getting higher and higher, the circulating cooling function of the equipment body is not reasonably designed, resulting in abnormal situations such as high-temperature overload during high-speed continuous heating production, increasing the equipment failure rate. In addition, limited by the use of special products, the size of the current heating device is relatively fixed, lacking the flexible adjustment function in the horizontal and vertical directions, which is not conducive to the flexible application of products.
