  • RecoDust—An Efficient Way of Processing Steel Mill Dusts

     · As a reusable secondary raw material resource the steel mill dust contains a high amount of iron and zinc. Nowadays most of the steel mill dusts are processed under the Waelz-Process. However this process is limited or impossible without additional dust treatment and can only be operated economically with zinc contents over 20 wt .

  • Annealing of electrical steel IEEE Conference

     · Abstract Annealing of electrical steel while classified as a heat treating operation and subject to conventional CQI-9 audit principles is almost exactly the opposite of most other heat treating operations. One of the primary reasons for heat treating of steel is to harden or strengthen it via carburizing nitriding or similar where performance is measured in terms of hardened case depth.
