Studies of Conventional and New Technologies for Preparation of Iron Ore Raw Materials at Iron Making Plant of Pao Severstal to Evaluate Prospectives for Reduction of Ecological Load on Environment


The experts of Centre for Raw Materials Investigations (CRMI) have conducted research into the usage of recycled materials in the following technological processes: sintering and briquetting. Research shows variation in emissions containing sinter gases and qualitative characteristics of the finished product (cold and hot sinter strength). It is suggested that involvement of recycled waste products of steelmaking and chemical processes shall be increased using the method of vacuum extrusion.

Keywords: sintering, recycled materials, sinter gas, briquettes
