  • RecoDust—An Efficient Way of Processing Steel Mill Dusts

    Apr 05, 2019RecoDust is believed to be an efficient way of processing steel mill dusts to produce reusable secondary raw material resources. The rising costs of the steel production process and the increasing public attention towards environmental protection have caused steel plants worldwide to focus on emission-reduction processes and circular economy. As a reusable secondary raw material

  • How to weld through mill scale

    Jan 26, 2019The FCAW process is well-suited for welding through thick mill scale because of the high level of deoxidizers in the wire and the slag system it produces. The FCAW wires most used to weld mill scale are E71T-1 for welding in all positions and E70T-1 for welding in flat and horizontal positions only.

  • Roll Drive Design Considerations for Steel Mill Rolling

    The conveying system that links one process to another is the lifeblood of any rolling mill. Lose this ability to move product and you lose production. As anyone in the steel industry knows, if a single component can shut down production of a multi-million dollar steel mill, this component justifies individual design consideration.
