AI Technical Summary
Existing scrap steel recycling processes are characterized by high energy consumption, high costs, and numerous impurities. In particular, zinc contaminates furnace lining materials, leading to a decline in molten steel quality and severe hydrogen embrittlement defects.
A gas combustion device is used to generate reducing flue gas, which is then used to heat the scrap steel material through a preheating chamber and a heating chamber to remove moisture and oxidize zinc. Inert gas pipelines are used to cool the material trolley and track. The ratio of gas to air is controlled to ensure a reducing atmosphere and reduce oxidation and impurities.
It effectively reduces energy consumption, increases scrap steel recovery rate, reduces impurities, ensures high-quality steel production conditions, and lowers production costs.
