This project includes a 2 * 150 steel continuous feeding electric furnace dust removal system, as well as corresponding refining dust removal systems such as LF furnace, continuous casting, and feeding systems. The electric furnace dust removal system adopts a combination mode of primary flue gas exhaust inside-furnace + secondary flue gas exhaust outside-furnace+third flue exhaust on the roof" to capture the electric furnace flue. The capture hood meets the requirements of a capture rate greater than 98%, and the dust emission concentration is ≤ 10mg/Nm3.

This project is a newly built electric furnace with refining, continuous casting and other equipment, providing dust and flue gas capture and ultra-low emission control for the overall steelmaking workshop; At the same time, a quench boiler is equipped for the internal discharge of high-temperature flue gas during the electric furnace smelting process, which not only meets the requirements of rapid cooling of dioxins, but also achieves efficient waste heat recovery of flue gas. The generated steam is integrated into the steam pipeline network in the factory area, greatly reducing the direct operating cost of the enterprise.
