Abstract: In the current research, different cooling processes for getting an ultra-fast cooling rate for a hot static plain carbon steel plate are studied. Depending upon the initial surface temperature and the final microstructures of dual-phase steel, the first type of ultra-fast cooling is late ultra-fast cooling, and second type is early ultra-fast cooling. Late ultra-fast cooling is studied by a water spray and air-assisted spray cooling process, and early ultra-fast cooling is studied by air-assisted spray only. The heat transfer analysis on the above cooling processes show that air-assisted spray has an excellent control on the rate of cooling.
