Method for automatically correcting tracking process of heating furnace

Abstract

The invention discloses a method for automatically correcting the tracking process of a heating furnace. The method comprises the following steps of: after a walking beam moves by a step pitch, obtaining the step pitch of the walking beam, a laser detection mark and an overflow quantity of blanks after laser detection; on the basis of the obtained step pitch of the walking beam, updating the positions of the blanks in the heating furnace; on the basis of the laser detection mark, the laser detection overflow quantity and the updated blank positions, determining whether the positions of the blanks need to be subjected to tracking correction or not; when the shortest position in a plurality of blanks is less than the position of a targeting laser and the laser detection mark is equal to 0, carrying out advanced tracking correction on the updated positions of the blanks in the heating furnace; and when the shortest position in a plurality of blanks is greater than the position of the targeting laser and the laser detection mark is equal to 1, carrying out lagging tracking correction on the updated positions of the blanks in the heating furnace.

Description

technical field [0001] The invention relates to an automatic correction method for process tracking of a heating furnace, more specifically, to an automatic correction method for process tracking of a heating furnace for automatically judging and correcting the position of a billet. Background technique [0002] The heating furnace is an important equipment for steel rolling production, which provides continuous high-temperature blanks for subsequent processes. The heating furnace has the characteristics of large capacity and rapid heating according to the process requirements. The currently used heating furnaces can generally accommodate dozens or even hundreds of blanks at the same time, and the combustion control model is used to automatically heat the blanks. For the billet of the heating furnace, the position information of the billet is obtained by tracking. Tracking is the basis of control technology. Only when the tracking is accurate or the tracking position is wi...

AI Technical Summary

Problems solved by technology

Due to the system error and protection of the steel loading machine, stepping machine and other equipment itself, a large number of errors and long-term accumulation of errors occur, so there is a problem that the actual tracking of the billet and the calculated tracking deviation exceed the allowable range of error, resulting in the position of the displayed billet and the actual position. Does not match, resulting in a decrease in the quality of the billet heating

[0003] The traditional tracking correction method of heating furnace is to manually adjust the tracking position of some or all billets when there is an obvious tracking error, which inevitably leads to untimely adjustment or overshooting, etc., and also increases Artificial labor intensity, on the other hand, also affects the heating quality of the product
