  1. 21. Quenching a steel plate by water - impinging jets and different simultaneous flow rates

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Pablo Martinez; [2019]
    Keywords : Quenching; steel; plate; cooling; water- impinging jets; cooling rate; subcooling; temperature.;

    Abstract : Regarding the great importance of fast cooling in steel industry for the production processes, a deep understanding of heat transfer and fluid dynamics must be held. A steel plate is heated up until a maximum temperature of 700 ⁰ C to be the n cooled down seconds later by a configuration of multi ple impinging water jets. READ MORE
