AI empowers the transformation and upgrading of the steel industry. Another project of Yonglian Huike was successfully landed

Recently, the HBSAI intelligent combustion system of Yonglian Huikeshi, a subsidiary of AIMS, was successfully implemented in the No. 6 blast furnace of Yonggang Steel. This is another important practice of Yonglian Huikeshi leveraging artificial intelligence technology to enable industry transformation and upgrading.

The HBSAI intelligent combustion system is based on advanced technologies such as artificial intelligence and big data. It collects real-time dynamic process data of combustion, builds a multi-target integrated model centered on enhanced learning and expert experience, uses the minimum gas consumption and the meeting of flue gas temperature standards as evaluation indicators, conducts intelligent prediction of the furnace condition, selects the optimal coal-air ratio strategy, replaces manual combustion with AI combustion, scientifically controls parameters such as furnace temperature and air-fuel ratio, and achieves the best furnace condition.

Before the renovation of the hot air furnace of the No. 6 blast furnace at Yonggang Steel, the furnace condition was greatly affected by factors such as the calorific value of the gas and the pressure of the pipelines, and it was difficult to achieve stable furnace conditions through manual control. At the same time, under manual control, the unreasonable ratio of gas to air led to the gas consumption remaining in an unreasonable state for a long time.

The technical expert team of Yonglian Huike adopts an independently developed AI algorithm model based on the actual situation of Yonggang's on-site hot blast stove to achieve automatic burning, adaptive optimization of burning status, intelligent shutdown, and safety protection of the hot blast stove. It can effectively reduce the consumption of gas in the hot blast stove of No.6 blast furnace, and this alone can generate economic benefits of over several million yuan for Yonggang every year.  

As one of the main equipment in steel enterprises, the automation level and optimized operation level of blast furnace hot blast stove directly affect the production capacity and energy consumption of the entire steel plant. However, due to differences in construction time, design volume, operational personnel level, and management level of blast furnace hot blast stoves in China, the control level of blast furnace hot blast stoves varies greatly among steel enterprises. The adjustment of coal air ratio relies on manual experience, the control accuracy of combustion self-control system is insufficient, the air supply system and cycle are fixed, and the air flow adjustment is not timely, resulting in a large excess air coefficient. These factors lead to unstable furnace conditions, increased gas consumption, insufficient combustion, and unstable product quality.  

The achievement of the goals of "peak carbon emissions" and "carbon neutrality" is not a smooth road. The steel industry is facing many challenges, such as a coal based energy structure, a long process structure dominated by blast furnaces and converters, and uncertainties in the application of low-carbon or zero carbon technologies. Traditional energy-saving, emission reduction, and energy management methods not only require greater investment, but also have a significant impact on steel production capacity.

In this context, digitization and intelligence have become the trend of the steel industry towards; Dual carbon target; As an important means of advancing, Yonglian Huike came into being spontaneously. Relying on the industry background of Yonggang Group, Yonglian Huike applies the AI technology of AIMS, devotes itself to enabling the development of the industry with cutting-edge technologies such as AI, big data, cloud computing, and industrial Internet, deeply studies the process technology and carbon reduction process of the steel industry, and promotes and applies them on a large scale, helping to accelerate the green development of China's steel industry.
