Robots in the steel industry

For large-scale iron and steel enterprises, the long-process iron and steel production process mainly includes coking, sintering, pelletizing and blast furnace ironmaking before ironmaking. In the steelmaking stage, there are mainly processes such as converter, refining furnace, continuous casting, and rolling. Process and subsequent processing stages of rolled products.

The iron and steel production process has continuous, discrete, and semi-continuous coexistence, which is relatively complex, and most of the production process is semi-structural and unstructured, and it is difficult to optimize the processing. The combination of artificial intelligence technology and traditional methods is to solve this problem. Class questions provide a way. Artificial intelligence technology has penetrated into all aspects of the steel production process, such as product design, molten iron quality prediction, process control, product quality judgment, equipment fault diagnosis, pre-iron procurement and batching optimization, production planning and scheduling, etc.

The traditional iron and steel industry is a high-energy-consumption and high-pollution industry, which has the characteristics of high temperature, high dust, high noise and other harsh environments and high risks such as liquid molten metal. It is suitable for replacing manual operations with industrial robots, thereby reducing the safety risks to employees. And labour intensity, improve labour efficiency.

At present, most of the robot projects successfully applied by iron and steel enterprises are concentrated in steelmaking and post-steelmaking, which is also related to the fast pace and high degree of automation of the production line itself. Such as temperature measurement and sampling in front of the steelmaking furnace, automatic slag addition to the continuous casting machine, inspection and sampling, billet number spraying, steel coil spray printing, bundling, unbundling, labelling, etc.

Why to use robots in the steel industry?

In the iron and steel industry, the replacement of manual operations by industrial robots mainly has the following advantages:

1. Robots replace humans in labour-intensive jobs

For highly repetitive and labour-intensive operations, robot operations can greatly reduce the intensity of labour and avoid injuries caused by repetitive labour. For example, unmanned driving, ladle slag removal, steel bar counting, finished product labelling and other positions.

2. Robots replace humans in high-risk positions

For some operations in the iron and steel industry that have toxic and harmful gases and high-temperature harsh environments, using robots to replace manual operations can protect workers from harsh environments and improve operating standards and labour efficiency. Such as temperature measurement and sampling, welding, spraying and other posts.

3. Robots are engaged in positions with harsh working environments

For some dusty and harsh environment operations in the iron and steel industry, robots are used to replace manual operations, such as mixing, stacking and reclaiming, and workshop cleaning in raw, fuel and auxiliary material factories, which can protect workers from harsh environments and improve Operating standards and labour efficiency.

4. For standard operations such as quality inspection, temperature measurement, and sample inspection, robotic operations can avoid misjudgments, false judgments, and inaccurate measurements caused by human errors, which is conducive to the realization of standardized operations.

5. Realize the digitization and informatization of traditional crafts through industrial robots, and use the communication capabilities of robots to realize the “non-landing” of data flow, which greatly improves the timeliness and accuracy of information transmission on production lines.
