The smart scrap grading system, with a total investment of 10 million yuan and 9 months of in-depth construction, was put into use. It has completely replaced the traditional manual grading work, and realized the standardization, informatization, intelligence and unmanned operation of scrap grading. It is the first intelligent and innovative application project of outdoor high-precision scrap grading and multi-technology integration in China.
As recycled steel raw materials, scrap steel is of great significance to the green and low-carbon transformation of the steel industry. Zhongtian Iron and Steel currently uses nearly 2 million tons of scrap steel per year, involving five grades of charge and heavy scrap. It is reported that the traditional grading of scrap steel mainly relies on manual identification and grading, especially the harsh environment of the grading site, there are problems such as large subjective deviation, high labor intensity, weak transparency, and many grading objections.
In March 2021, Zhongtian Iron and Steel started the construction of a smart scrap grading system project. Based on 5G data transmission, artificial intelligence, machine learning, intelligent identification technology and remote monitoring technology and many other innovative technology applications, the system has built the most complete scrap database in the industry, and realized pixel-level segmentation of scrap contour and scrap shape. automatic identification, further solidify the identification standard, improve the accuracy of judging, and achieve the consistency of judging.
Compared with the traditional manual grading and indoor intelligent grading, the outdoor intelligent scrap grading system deployed and implemented by the company can still achieve indiscriminate and high-precision identification and judgment of scrap grades in harsh environments such as rain, fog, snow and wind. At the same time, it integrates the group's operation management and control platform to realize
intelligent management and control of the whole process of scrap steel business from contract procurement, intelligent grading, inventory management, settlement tracking, etc.
It is reported that after the system goes online, there is no need for manual intervention in the scrap steel business from entering the plant to unloading, inspection, leaving the factory, and data docking to the management and control system. The system can issue a grading result at the moment when the unloading of each truck is completed, and 2 post personnel can be optimized for each point and each shift, realizing unmanned on-site operations, and completing more than 10,000 tons of scrap steel inspection each month. The grading accuracy rate is 100%.
