Baoshan Iron and Steel Co., Ltd. has developed the latest sintering process: microwave sintering, which uses electricity to replace coal to solve the problem of carbon emission.

SHANGHAI, Apr 13 (SMM) – Baoshan Iron and Steel Co., Ltd. has developed the latest sintering process: microwave sintering, which uses electricity to replace coal to solve the problem of carbon emission. Generally, the carbon dioxide generated by the sintering process accounts for about 15% of the entire ironmaking process. According to calculations, the traditional sintering process produces about 600 mg /m³ of carbon dioxide and other gases for every mt of finished raw materials produced, while the microwave sintering process produces just 25 mg/m³ of carbon dioxide and other gases, which means 99% of pollutant gases can be eliminated through this new process. At the same time, it can also reduce the use of fossil energy such as coal.
