A fully automatic steel loading method for slab number detection based on machine vision

Abstract

The invention provides a machine vision-based automatic slab number detection method for steel loading, comprising: collecting pictures of slab numbers at different positions of the moving slab, and performing preprocessing to obtain effective slab number pictures; adopting machine vision The technology recognizes the effective slab number picture to obtain the slab number; according to the identified slab number, matches with the MES database and the continuous casting database to obtain the original PDI data of the slab; conducts actual measurement of the parameters of the slab before the furnace, and The original PDI data is compared to judge the reliability of each measured parameter; based on the reliability of each measured parameter of the slab, combined with the predetermined furnace charging rules, automatic release or alarm processing is carried out. The invention can realize automatic checking and steel loading in front of the furnace, can effectively speed up the rhythm of steel loading in front of the furnace, and improve the production efficiency of the entire production line.

Description

technical field [0001] The invention relates to the technical fields of metallurgical machinery, automation and rolling, in particular to a fully automatic steel loading method for detecting slab numbers based on machine vision. Background technique [0002] With the continuous deepening of digitalization and intelligence in the manufacturing industry, the metallurgical industry has also ushered in an opportunity for reform. Among them, the intelligence of the heating furnace system is the premise and basis for realizing the intelligence of the entire production line. However, at present, the heating furnace is precisely the weakest link in the automation level of the entire production line. First, because there are many interactive links between the upstream and downstream of the heating furnace, the process is flexible and changeable; second, because the materials in the heating furnace have multiple destinations , it is difficult for the system to automatically track all...

Problems solved by technology

[0004] Based on this, the present invention proposes a fully automatic steel loading strategy for slab number detection based on machine vision, ending the history of multiple manual control links and chaotic slab management in front of the furnace; Manual operation results in low production efficiency, high labor intensity, and prone to mixed steel, which seriously affects the production rhythm and later product quality judgment; it realizes automatic tracking and control of materials from continuous casting to furnace loading, and gets rid of years of The "bottleneck" that affects the production rhythm
