Recently, the list of typical application cases of "Artificial Intelligence +" in state-owned enterprises in Zhejiang Province in 2025 was announced, and the case of "Plate Hook Intelligent Identification and Scrap Steel Intelligent Grading Integrating Deep Convolutional Neural Network" applied by Ningbo Iron and Steel Co., Ltd. was selected.

This selection was initiated by the State-owned Assets Supervision and Administration Commission of Zhejiang Province. After several rounds of strict screening, such as unit declaration, prefecture and city recommendation, preliminary review of materials and expert review, it focused on key areas such as strong strategic significance, high economic returns and close connection with people's livelihood, and systematically sorted out the innovative application achievements of artificial intelligence in production, management, service and other links of state-owned enterprises in the province, and accelerated the special action of "artificial intelligence +" of state-owned enterprises.

With its remarkable technological advancement and industrial applicability, Ningbo Iron and Steel's participating case stood out from many projects in the province, providing an excellent model for technological innovation and application of state-owned enterprises.

It is reported that in view of the pain points such as high safety risks of plate hook operations, low efficiency of manual grading of scrap steel and many controversies in traditional operations in the steel industry, Ningbo Iron and Steel innovatively integrated deep convolutional neural network, machine vision and 5G technology to successfully build intelligent plate hook identification and scrap steel intelligent grading system.

The system replaces manual labor with AI, which significantly improves operation safety and grading efficiency, effectively drives the industry to move towards green manufacturing and digital transformation, and builds a new industry development model of "technology cost reduction + ecological efficiency improvement".

Next, Ningbo Iron and Steel will continue to take technological innovation as the guide and digital intelligence empowerment as the engine to deepen the application and expansion of AI technology in green manufacturing, smart logistics and other fields.
