Problems solved by technology

At present, the size of the billet entering the heating furnace is 2500mm ~ 4100mm. When the billet smaller than 2700mm is positioned, the contact surface is not flat due to the contact between the lower surface of the billet and the roller table, and the billet is uneven and convex, resulting in the billet after positioning in a free state. Due to the slippery phenomenon due to inertia, it deviates from the centerline of the walking beam, causing hidden dangers. At this time, the operator needs to supervise the installation on site and adjust it manually, which will affect the rhythm of steel installation

Embodiment Construction

[0017] Technology of the present invention is:

[0018] 1. Before the billet enters the heating furnace, add the laser detector at the entrance of the heating furnace and the position of the mounting bracket, so that the laser detector can be accurately irradiated on the center line of the roller table, and the angle is controlled between 30 degrees and 60 degrees. At the same time, reduce the gap at the opening end of the front end of the laser detector itself to (2mm-5mm), and turn the rotary button behind it clockwise to adjust the sensitivity indication value from 4 to 8.

[0019] The conveyance of the steel billet into the furnace and the precise positioning of the billet on the furnace side are carried forward by the roller table, and pass through 3 automatic detection components during the transportation process (one of which is a newly added positioning laser detector, and one is an original tracking device). Grating, 1 photoelectric encoder for positioning), used for ...

Abstract

The invention relates to the technical field of heating furnace automatic controlling, and discloses a method for realizing accurate positioning of a steel billet delivered into a heating furnace. According to the invention, logic of automatic controlling is skillfully combined with the function of a furnace roller table converter. Without external braking equipment, slipping phenomena occurred after positioning of steel billets with lengths smaller than 2700mm are avoided. With the method, accurate positioning of any sized steel billet can be realized, and slipping does not occur after positioning.

Description

technical field [0001] The invention belongs to the technical field of automatic control of heating furnaces, and in particular provides a method for realizing precise positioning of steel billets in a heating furnace, which can realize precise positioning of billets of any size without slippery phenomenon after positioning. Background technique [0002] The heating furnace of the steel rolling department of Shouqin Company in Qinhuangdao adopts a walking beam structure. To ensure that the billet does not deviate in the furnace, it is necessary to accurately position the billet before entering the furnace so that the center line of the billet is aligned with the center line of the walking beam. be consistent. Therefore, the positioning work before the billet is put into the furnace is particularly important. At present, the size of the billet entering the heating furnace is 2500mm-4100mm. When the steel billet smaller than 2700mm is positioned, because the lower surface of ...
