Slag Dry Granulation
Tenova developed a valorization process for the EAF and LF slag as a raw material. The process consists in the dry cooling of the liquid slag eventually mixed with residual steel by forced air stream to allow their fast solidification.
Overview
Our dry slag granulation technology transforms molten slag from steel furnaces into granules using air stream, eliminating the need for water.
The flexibility of the process allows obtaining granules of different sizes and with different ratio between crystalline and amorphous phases to respond at the request of the final user. This innovative process integrates seamlessly into existing steel production workflows and is specifically designed to meet the needs of industry stakeholders and regulation objectives. By replacing traditional water-based methods with air, our technology reduces operational costs and enhances environmental sustainability, giving steel plants a competitive edge and aligning with circular economy goals for industrial waste reduction and resource recovery.
