Steel Dust Wealz Rotary Kiln For Zinc Waste Material Recovery

Recycling Steel Dust

Zinc-coated galvanized steel scrap is the most widely used feedstock for Electric Arc Furnace (EAF) steel production. World crude steel production reached 1,66 billion metric tons for the year 2014, up by 3.9% compared to 2013 (World Steel Association). Around 26% of crude steel is produced using the EAF technology.

Zhengzhou Hengyang Industry deploys the reliable rotary Kiln technology that successfully processes over 80% of the world’s recycled steel dust (EAF Dust). The rotary Kiln process is an established, energy-efficient and resilient technology used to treat zinc containing materials and residues.

During the EAF process, the high temperatures required to melt the feed material produce a zinc byproduct (EAF dust) that leaves the furnace along with the off-gases. The gases are filtered and the EAF dust is collected in bag houses.

The EAF dust waste steam is considered a hazardous material due to the potential for the heavy metals to leach into the ground, contaminating ground water and sewage systems.

The EAF dust generated by steel mills can be recycled in an economically viable way using the Waelz Kiln technology. The recycling process is part of the larger steel industry loop that allows the reuse of two important natural resources - zinc and iron.
