Original Abstract
The spray cooling is a common cooling method in the steel industry (continuous casting, hot rolling, product cooling or heat treatment). The water is sprayed on the hot surface by the nozzle which transforms the water stream into droplets. Sprays can provide very high cooling rates with the benefit of the regulation of the cooling process. The spray cooling is influenced by several parameters. They can be divided into two groups. The first group deals with spray parameters like water impact density, water temperature, water additives and droplets size. The second group relates to cooled surface: temperature, velocity, roughness and presence of scales. This paper describes non-stationary spray cooling experimental measurement and deals with factors influencing the spray cooling. The influence of each factor is experimentally investigated and the influence on the heat transfer coefficient or Leidenfrost temperature is described based on experimental results and or existing publications. findings and gives insight into various aspects of the hot rolling process.
