  • Optimization of descaling nozzles in a hot strip mill

    Optimization of descaling nozzles in a hot strip mill

    In hot rolling, the surface quality of the finished strip depends on the performance of the descaling equipment in the roughing and finishing trains. The design of descaling systems and nozzles has been improved over the years step by step, thus ...

  • Flatness and profile the problems that can exist in the design of the spray actuators

    Flatness and profile the problems that can exist in the design of the spray actuators

    Flatness or shape control is one of the primary factors by which the quality of strip is measured; attention must therefore be paid to the work roll temperature and internal temperature distribuition if accpetable quality is to be achieved.

  • A quantative study into the comparative efficiency of flatjet and full cone spray nozzles when applied to the application of work roll cooling.

    A quantative study into the comparative efficiency of flatjet and full cone spray nozzles when applied to the application of work roll cooling.

    Many myths exists around the use of spray nozzles in the process of helping to control flatness of Steel or Alumnium trip. Whether in the heat or cold rolling process, flatness is one of the primary factors by which the quality of strip is measured ...

  • Descaling with high pressure nozzles

    Descaling with high pressure nozzles

    Descaling of steal in hot rolling processes is an application of high-pressure spray nozzles. The impact force and pressure of theses nozzles can be determined using Newton´s 2nd and 3rd axiom. This allows calculating the impact pressure ...
