Abstract

The invention relates to a plate rolling process heating device and method. The plate rolling process heating device comprises a movable induction coil assembly for overall heating, a crawler-type induction coil assembly for heat supplementing, a first thermodetector, a second thermodetector and plate shape instruments. A conveyor belt is used for driving a plate to move at a uniform speed on a production line, and overall induction coils and the crawler-type induction coil assembly are used for carrying out preliminary heating and heat supplementing on the plate, so that the overall plate reaches the optimal rolling temperature. The crawler-type induction coil assembly moves synchronously with the plate, and the thermodetectors and the plate shape instruments detect the surface temperature and shape of the plate in real time, so that point-to-point accurate heat supplementing of small coils in the heating process is realized, the phenomenon of overlarge local temperature difference caused by poor plate shapes, center waves, plate shape changes in the heating process and other uneven plate surface shapes is reduced, the plate is accurately and evenly heated before rolling, ideal temperature distribution is achieved, the heating requirements of the plate in different rolling stages are met, and the rolling quality is improved.

Description

technical field [0001] The invention belongs to the technical field of plate continuous rolling, and in particular relates to a heating device and method for a plate rolling process. Background technique [0002] In today's world, steel rolling technology is developing rapidly. Steel rolling production has made great progress in automation, high precision and continuity, and has become a mature, stable and efficient production line. Plate and strip is also a widely used steel. The output of plate and strip in my country accounts for 45% to 55% of the total steel output, and most of the plate and strip are produced by rolling. The rolling method is used to produce plates, which not only has high productivity and many varieties, but also is easy to realize mechanization and automation. [0003] In actual production, most plates are heated or preheated by a heating furnace. With this heating method, the deformation of the plate is large, and the energy utilization rate is lo...
