The 2-million-mt pellet belt sintering production line of Dagang Group has been successfully put into operation!

On June 1, Fangda Dazhou Steel's 2 million mt pellet travelling grate production line successfully produced pellets, marking a significant achievement in the construction of the pellet unit project in the new plant area and the official commissioning of the first pellet production line since the establishment of Dazhou Steel.

Fangda Dazhou Steel has built a new 2 million mt pellet production line that applies advanced, environmentally friendly, and energy-efficient travelling grate technology. Its main economic and technical indicators have reached the advanced domestic level. It adopts efficient wet desulfurization + SCR denitration technology to fully achieve ultra-low flue gas emissions. The travelling grate pelletizing technology represents the development direction and mainstream process of the industry, and it is also a production line encouraged by the state in the steel industry. Centered on low-carbon economy, energy conservation, emission reduction, clean production, and efficient resource utilization, the process energy consumption is ≤25 kg, making it a landmark project.

The travelling grate in the pelletizing process is equipped with dedicated coal gas burners arranged on both sides. Each burner is equipped with an automatic regulating device to precisely adjust the temperature and coal gas pipe pressure. With a designed annual production capacity of 2 million mt of pellet ore, it can produce two types of pellet ore: acidic oxidized and basic, effectively improving the permeability and reducibility of the blast furnace, and providing strong support for the enterprise to achieve the "win-win" goal of energy conservation, environmental protection, and economic benefits.

Since the project commenced construction in January 2024, the Sintering and Pelletizing Material Yard Project Department has closely focused on the construction goals and tasks, working in close collaboration with the general contractor, WISDRI Engineering & Research Corporation Limited (Wuhan Iron and Steel Design & Research Institute Co., Ltd.), and organizing elite teams. They have overcome unfavourable factors such as summer rainstorms and high temperatures, as well as winter fog and severe cold, to complete the construction task on schedule with high standards and quality, laying a solid foundation for the timely commissioning of the 2 million mt pellet production line.
