Sustainable Steel Excellence: Inside Baosteel's High-Tech Silicon Steel Production Line

Introduction

The Silicon Steel Division's Q618/Q718 production line at Baosteel is a key facility in implementing new development concepts and the national dual-carbon strategy, driving the green and low-carbon energy transition. It is a specialized production line for high-grade non-oriented silicon steel (What is silicon steel? )used in new energy vehicles, equipped with the world's leading process and manufacturing technologies.

Innovative Technologies and Green Manufacturing

The Q618/Q718 production line has pioneered the application of intelligent process control and online performance feedback control technologies, achieving automated process control. It employs a novel annealing process developed by Baosteel, which enhances product performance while reducing exhaust emissions, contributing to the national carbon neutrality goal.

Smart Equipment and Efficiency

The full deployment of intelligent equipment has seen a stable utilization rate of over 95%, significantly improving labor efficiency. With the integration of multiple industrial robots, production efficiency, and control precision have been greatly increased.

Smart Manufacturing Process

The Silicon Steel Workshop has achieved end-to-end smart manufacturing, building on the smart production line, ensuring every steel coil experiences a "smart life." The high-grade non-oriented silicon steel intelligent roll grinding room facilitates production and significantly reduces labor intensity in the rolling area. It is the most automated and intelligent roll grinding room in China, equipped with an intelligent roll warehouse, RGV roll pusher, roll lifting, and turning devices, automatic disassembly machines, fully automatic roll grinding workshop management and scheduling systems, and more.

Precision Grinding and Automated Loading

The roll grinding room is also equipped with high-precision automatic grinding machines and automatic loaders, enabling fully automatic and precise grinding of rolls, with an annual capacity of approximately 20,000 rolls. After grinding, the rolls are automatically transported to the intelligent backup roll storage area, completely replacing traditional manual operations, reducing safety risks, and doubling work efficiency. The intelligent roll grinding room's operation and management system tracks the entire lifecycle of the rolls online, achieving intelligent interaction between grinding and production.

Intelligent Roll Change and Lifecycle Tracking

Utilizing fully automatic roll change technology, the intelligent backup roll storage system can replace used rolls with new ones according to planned requirements. The intelligent grinding room's operation and management system tracks the entire lifecycle of the rolls online, achieving intelligent interaction between grinding and production.

Product Finishing and Quality Assurance

After production in the Q618 and Q718 lines, the products are further processed in the finishing area by multifunctional robots to meet customer needs. The finishing exit multifunctional robot is the first application in the steel industry of a robot combination working in unison. It consists of two six-degree-of-freedom robots, with six rotating axes including the base, waist, arm, forearm, wrist, and wrist rotation axes, allowing it to move freely in three-dimensional space to complete various tasks in the complex working conditions of the finishing area.

Control Systems and High-Precision Operations

The control system uses high-performance computers and advanced control algorithms to achieve high-precision, high-speed, and stable motion control. It also features a human-machine interface for controlling and adjusting the robots. The two "arms" can carry two high-definition cameras to scan and photograph the end faces of steel coils, with a high-end vision system that directly displays end face quality to quality inspectors. The robots are highly flexible, precise, and adaptable, suitable for efficient and automated production processes. Additionally, the two "arms" can perform tape and label applications simultaneously, doubling the efficiency of the operation. The labels and tapes are consistently applied to the steel coils, avoiding the risk of label information errors that may occur with manual application, and providing customers with a visually appealing product appearance, fully showcasing the charm of modern silicon steel manufacturing and allowing users to experience Baosteel's smart manufacturing and services.
