Dust Collection System in Metalworks and Steel Plant

The direct reduction of the iron ore derives a product called direct reduced iron or sponge iron. They have the same contents as in pig iron and can be used as feedstock for furnaces in the mini mills. Sponge irons, if left unprotected, it can lead to rusting and even catch fire.

Direct reduced iron Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example bein
