    Influence of Water Temperature on the Cooling Intensity during Continuous Casting and Hot Rolling

  • Original language description

    Two types of nozzles were tested to find out the influence of the water temperature on cooling intensity. The first type was a mist nozzle used in the secondary cooling area of a steel slab casting machine. The second type was a flat fan nozzle usually used during hot rolling and heat treatment process of rolled strips. These laboratory measurements of cooling intensity were performed in a temperature range of water temperature from 20 C to 80 C. A strong influence of the water temperature on cooling intensity was found. Changing the water temperature from 20 C to 80 C caused a change of heat transfer coefficient. For mist nozzle was found slightly increasing cooling intensity with growing water temperature. The difference was about 30 W m-2 K-1. For flat fan nozzle was found the decreasing cooling intensity with growing water temperature. The difference was about 110 W m-2 K-1. The main effect was not the change of heat transfer coefficient but the shift of Leidenfrost temperature to a lower temperature area. The change of water temperature from 20 C to 80 C caused the change of Leidenfrost temperature about 130 C for both nozzles. This can be a significant change of cooling and can affect the cooling character in industrial applications.
