According to the National Bureau of Statistics, in the first half of this year, China's crude steel output was 527 million tons, a year-on-year decrease of 6.5%; pig iron output was 439 million tons, down 4.7% year-on-year; Steel output was 667 million tons, down 4.6% year-on-year. The data shows that in the first half of the year, the market demand was lower than expected, the steel output showed a trend of decreasing development compared with last year, and the efficiency of the steel industry declined in the same period.
In the face of the complex situation and unprecedented challenges, the steel industry should take the supply-side structural reform as the main line, focus on the two themes of green and low-carbon transformation and intelligent manufacturing, and effectively solve the "pain points" that restrict the development of the industry, the problems of technical research and the joint innovation of low-carbon metallurgical technology, so as to realize the development of the steel industry itself and further promote the high-quality development of the metallurgical industry.
Combining excellent quality management with efficient and reliable processes in the metallurgical industry requires flexible and reliable equipment and machinery to help achieve high quality and efficient production. As a specialist in sensors and automation, Balluff is the ideal choice for sensors, systems and network technology for a wide range of production needs.
BTL magnetostrictive sensors from Balluff
What are the applications in the metallurgical industry?
Technical expertise across the entire value chain in metallurgical processes:
Coking plants→ sintering plants→ blast furnaces→ converters→ electric arc furnaces→ continuous casting lines→ hot rolling and plate production→ cold rolling and surface processing
1. Application in the continuous casting process - to achieve flexibility in various forms of production
The quality of the steel is determined by the continuous casting process, which requires flexible and reliable production equipment in the continuous casting process. Sensors and systems from Balluff meet these requirements and ensure continuous processing of a wide range of products for efficient production.
Provides security for ladle control
Ladle control requires a high degree of reliability. To be safe, on-site production systems must be redundant. Multiple redundant BTL magnetostrictive sensors are equipped with up to three independent measuring systems in one housing to meet all the requirements for safe operation on continuous casting lines.
peculiarity
2-3 channel redundancy
A variety of interfaces are available
Degree of protection IP67
Fast sensor replacement (no leaks)
Balluff's quick-change modules enable you to quickly and easily replace BTL magnetostrictive sensors in hydraulic cylinders. Since the entire sensor unit is replaced with a built-in waveguide, the hydraulic circuit remains closed at all times. This minimizes the risk of leakage and prevents dust from entering the hydraulic system.
peculiarity
The dimensions are the same as those of a standard rod position measurement system
This reduces the risk of leakage and prevents dust from entering the hydraulic system
Applies to analog, SSI, and DPI/IP interfaces
2 Application in the hot rolling/plate process – to ensure the continuous reliability of the production process
Hot rolled and plate production always requires strong forces, so production equipment is subjected to shocks, vibrations and strong forces in many areas. In the production of thick plates, high-performance equipment and suitable conditioning equipment are required for each process stage. Balluff offers you state-of-the-art technology to control all process stages, from slab to coil.
Slab guidance on the mill stand
Balluff BTL magnetostrictive sensors are ideally suited for positioning and guiding slabs in hydraulic cylinders, checking that the transverse guide is correctly configured and following the slab along its path on the mill stand so that they can safely and reliably cope with the enormous forces generated during the forming process.
peculiarity
Check the correct configuration of the transverse rails and trace the slabs
Resistant to harsh environments
Precise setting of the distance between rollers
The BTL magnetostrictive sensors from Balluff are IP69K protected and are ideally suited for setting high-precision roll-to-roll distances. It is absolutely hermetically sealed, withstands the extreme environmental conditions of steel mills, and does not require any additional protection during the continuous water cooling of the rolling mill stand.
peculiarity
IP69K protection
High precision, absolute seal integrity
It adopts the non-contact working principle, no wear and long service life
Thanks to its extensive experience in the field of sensors, Balluff is constantly expanding its product range through technological innovation and making it easy and flexible to select products at a cost-effective price. Balluff has developed products and technologies that are resistant to high temperatures, shocks and vibrations, and extremely robust in response to the harsh production environment, guaranteeing excellent machine performance and long-term stable operation at every stage of production. Embracing the wave of digital transformation, intelligent solutions from Balluff help you step into a new era of smart manufacturing.
