Blank removing method and system for increasing direct rolling average temperature, medium and electronic terminal

Abstract

The invention provides a blank removing method and system for increasing the average temperature of direct rolling, a medium and an electronic terminal. The blank removing method comprises the steps that steel rolling production site information and steel rolling constraint conditions are obtained; establishing a steel billet information tracking table according to steel rolling production field information; determining the length of a steel billet direct rolling sequence, and finding out all steel billet direct rolling sequences meeting steel rolling constraint conditions in the steel billet information tracking table through exhaustion search; and locking the billet direct rolling sequence with the highest average billet temperature. According to the method, all the steel billet direct rolling sequences meeting the steel rolling constraint conditions in the steel billet information tracking table are found out through exhaustion search, then the steel billet direct rolling sequence with the highest steel billet average temperature is found out from all the steel billet direct rolling sequences, rolling is conducted preferentially according to the sequence during steel rolling, the average waiting time of the steel billets is shortened, and the rolling efficiency is improved. Compared with the first-in first-out control logic in the prior art, the first-in first-out control logic has the advantages that the rolling line current during downstream rolling is effectively reduced, and the rolling energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent manufacturing, in particular to a method, a system, a medium and an electronic terminal for removing blanks for improving the average temperature of direct rolling. Background technique [0002] With the informatization upgrading and innovation of the traditional iron and steel industry, my country's iron and steel enterprises are also accelerating the exploration of digital, intelligent and unmanned transformation of traditional steel plants. The consumption of various energy sources in steel production accounts for about 30% of the product cost. From the continuous casting process to the rolling process, the slab is naturally cooled and then heated in a heating furnace for rolling. In this process, 65% to 90% of the total energy consumption is used for reheating the slab. Based on this, some iron and steel enterprises have started the research and development and application of billet dire...

Problems solved by technology

[0003] However, the current direct rolling process research is basically focused on the direction of equipment optimization and upgrading, such as increasing the casting speed, reducing cooling water, adding heat preservation covers, etc.; and the control logic of direct rolling strip removal is basically based on the maximum waiting time.

That is to say, after the billet reaches the diverter baffle, it waits for the direct rolling signal. When the direct rolling signal is received, the billet that first reaches the diverter baffle is released for direct rolling. When the waiting time is greater than a certain value, the billet goes off the assembly line. According to this control logic , the direct rolling billet can meet the minimum temperature requirement of direct rolling, but it will happen that all the billets are sent to the direct rolling after waiting for a long time at the diverter baffle, resulting in a low overall temperature of the rolled billet, large power consumption of the rolling line, and energy consumption Savings aren't great
