How is steel tempered in the 5G era? Look at Shougang's "smart steel" production line.

The fiery red billet passed through the production line at high speed, but the scene was empty; Tens of meters high unmanned crown block has also been endowed with "life". 5G high-definition images and AI edge calculation detection can help to dynamically operate and adjust it ... "How is steel tempered" in the 5G era? Shougang, as a century-old shop founded by 19 19, has become a "smart steel". In Shougang Jingtang Company, taking advantage of the characteristics of 5G high speed, large bandwidth and low delay, and integrating emerging technologies such as edge computing, machine vision and artificial intelligence, it has promoted the realization of few links and unmanned, helped the transformation and upgrading of steel manufacturing technology and equipment, and improved the production efficiency by about 15%.

Remote control to end artificial aerial work

On the continuous pickling production line of high-strength steel in Shougang Jingtang Company, 5G brings "life" to the crown block suspended in the air for more than 20 meters. One crane accurately lifts and unloads the steel coil from the car, and the other crane smoothly lifts the steel coil from the freight yard to the pickling workshop.

In the 4G era, such a flowing scene can be met but not sought.

In the memory of Yang Xiaodong, the crane master, in the past, the driver had to manipulate the crane to manually lift and unload steel coils in the pickling raw material warehouse and the pickling intermediate warehouse. Working at high altitude for several hours at a time is a great challenge to the driver's will and physical fitness, and the safety hazard is hard to avoid. Now, 5G has finally liberated the crane driver from the harsh working environment.

Relying on the high-definition cameras installed in the reservoir area and the traveling crane, and the network support based on 5G with low delay and large bandwidth, the staff sat in the clean and quiet remote control room of the 5G crane, watching the high-definition pictures sent back by 5G in real time, and tapping the operation keys like playing a game. The crane accurately advanced 10 meter, and then descended. Several tons of steel were slightly lifted, and the boom hardly shook, so the steel was steadily sent to the pickling workshop.

"There is no pungent sour taste and deafening mechanical roar, and it will not sweat after running for 5 minutes. 5G communication monitors the traffic control system and the ground control system in real time, and issues instructions. The crown block is like being given' life' by 5 G, "Yang Xiaodong said with emotion." Now I can sit in a comfortable air-conditioned room at the far end. In the past, the old masters sat in the cab of the crown block for hours, but it was too hot to drink more water. "

Peng Jun, an expert in Huawei's 5G steel industry, said that insufficient uplink bandwidth will lead to video jamming, which will affect the operator's judgment on on-site working conditions; If the control signal has a long delay, the operation will be "stuck", and in severe cases, the business will be stopped directly. The 5G scheme overcomes the disadvantages of inconvenient fiber laying and unstable WiFi capacity. Crane operators can realize remote and accurate hoisting with the help of monitoring video and operating handle.

Factories with IQ can reduce costs and increase efficiency.

The steel industry is the industry with the richest and most complex application scenarios in the field of industrial manufacturing, and it is also the industry with the most urgent demand for intelligence.

The speed is higher than 1Gbps, and the delay is less than 20ms. The characteristics of 5G bring the most active innovation elements to the industry. In Shougang Jingtang, the 5G industry private network and industrial interconnection platform have been formed, and multi-scene applications such as 5G safety production video return, 5G unmanned crane, 5G AR auxiliary inspection and 5G remote centralized control have gradually landed, which has promoted the integration of 5G technology and steel industry.

In the pickling raw material warehouse, intermediate warehouse and galvanized finished product warehouse, cameras all over the workshop clearly send real-time images back to the screen of the command center. Because of the extremely low delay, the controller can find the problem in the first time and deal with it in time.

Intelligentization not only improves the production efficiency, but also reduces the cost. Guo Liang, Director of Information Metrology Department of Shougang Jingtang Company, introduced that taking the function of 5G+ video feedback as an example, the application solved the problem of optical cable layout and transformation in the factory building, realized the access of later business at any time, and greatly reduced the operating cost.

Nowadays, the 5G crane has realized remote control, unmanned driving, video monitoring and return in the reservoir area, which greatly improved the output. If the integrity rate of loading and unloading links is close to 100%, 50% operators will be saved.

5G "Chemical Reaction" Produces Smart Factory

Driven by new technologies such as 5G, AI and cloud computing, the manufacturing industry is accelerating digital and intelligent upgrading. When the steel industry encounters 5G, it is accelerating to produce a brand-new "chemical reaction", which further strengthens Shougang Jingtang's confidence in building smart steel with 5G technology.

Guo Liang said with confidence that Shougang Jingtang is stepping up the coverage of the 5G network, and its innovative 5G application scenarios, such as unmanned parking lot, intelligent security in the park and automatic driving in the factory, will be realized one after another.

Statistics show that the scale of China's industrial digitalization reached 3 1 trillion yuan last year, and major industrial industries including steel are running faster and faster on the road of 5G digitalization. Driven by the technology engine of 5G, the development of intelligent manufacturing in China is constantly adding bricks and tiles.

According to Peng Jun, under the guidance of Shougang's experience, Valin Xianggang's "Black Light Factory" and "5G+ Smart Factory" and other demonstration projects have landed, and Baosteel, Hegang and Liugang also rely on 5G for intelligent application practice. A large number of steel enterprises began to use high-tech technologies such as 5G, AI, big data and cloud computing to carry out digital upgrading of the whole process, build a 5G smart factory, and promote the development of the industry in the direction of smart steel. The steel industry is expected to usher in a leap-forward development.
