AI Technical Summary

Technical Problem

The lack of effective treatment for flue gas and dust pollutants generated during the smelting process in medium-frequency induction furnaces leads to health hazards to workers, plant corrosion, and a decline in product quality.

Method used

A flue gas and dust removal device for a medium-frequency induction furnace was designed, including a flue gas and dust removal hood, a flue pipe and a cleaning component. The opening and closing of the flue gas and dust removal hood is controlled by a drive component, and the rotating shaft and cleaning brush are driven by a drive motor to clean the furnace mouth and the furnace body feed port. The device is combined with external dust removal equipment to collect soot.

Benefits of technology

It improves dust removal and cleaning efficiency, prevents dust accumulation, reduces cleaning difficulty, ensures product quality, reduces dust contamination in subsequent liquid metals, and extends the service life of the plant.
