Normally blast furnace inspections are completely manual & workers use a temperature gun to detect the surface temperature of the furnace, but Anshan Steel has figured out effective solutions to protect employee health and safety in this dangerous process. Angang Steel has adopted Hikvision's automatic temperature measurement solution to help the workers get further away from accidents and dangers, but closer to efficient and safe working conditions. Since 2019, Hikvision and the local partner, Yutai Security, have helped Angang Steel to apply thermal imaging to ironmaking blast furnaces. By evaluating the intensity of infrared radiation emitted from objects, thermal cameras have been used in detecting temperature anomalies before a fire starts. They find hot spots and invisible defects on machinery or electrical systems that could indicate a potential problem. They also perform non-contact measurements at the areas that are hard to reach manually.In Angang Steel's steelmaking workshop, the production process can be viewed remotely through Hikvision intelligent video devices and large screens. Through outstanding image brightness processing, high frame rate imaging, and other technologies, the image of molten steel dumping and desulfurization process in high-temperature and high-brightness environments can be generated, and then transmitted to the back end, allowing the workers to view and evaluate the production status in time and ensure the product quality. Through the real-time connection between front-end thermal imaging instruments and a back-end system, inspectors could use video streams from different positions in a furnace and monitor the temperature changes in specific areas of the furnace shell, generate reports, and receive timely warnings of temperature irregularities. Apart from the improved working environment, productivity has been raised too. The system is like a dedicated doctor for blast furnaces, which automatically measures temperature, generates reports, and also allows workers to search and compare historical data and monitor changes in the furnaces by receiving real-time alerts.Located in the heavy industry base in Northeast China, Angang Steel has a long history and a key role in the industry. In recent years, Angang Steel has actively tried innovative solutions for intelligent manufacturing and to solve problems of health and safety.Hikvision has been continually developing solutions to respond to the needs of the enterprise users in the steel industry, with solid R&D and rich scenario-based capabilities. Its intelligent technologies are helping more and more steel plants to improve quality and efficiency, as well as alleviating the workers' workload in harsh working environment and help them work safer and more efficiently.
