Ultra-Fast Cooling of Flat Metal Pate in a Modified Runout Table
Abstract
Cooling of metal components at the end of the steel production process is a highly critical step in production. The cooling process rate is time critical, and it helps determine various crucial steel properties. There is continuing research which is being done to help improve the process to boost the quality of steel produced as well as reduce the overall cost of production. Ultra-fast cooling involves the use of varied water and air pressures as the cooling media. Surface heat flux at each experimental condition was computed from the transient temperature history measured by K-type thermocouples embedded at the bottom surface of the plate. Peak heat flux on the surface of 2.954 MW/m2 was obtained using an inlet pressure of water 5 bar, pressure of air 3 bar, strip velocity of 5 cm/s, and nozzle to plate height of 100 mm for a starting temperature of 1123 K of the 4-mm-thick steel plate.
