摘要：

The Ultra Fast Cooling technology developed by CRM has been implemented on the hot strip mill of Carlam (Arcelor group), just in front of the down-coilers (late UFC). The results have demonstrated the controllability of the system and the great efficiency ( greater than or equal to 3.5 MWm(-2), 300degreesC/s on 4 mm thick strip) of the cooling unit. Increasing the cooling rate in a controllable way makes the production of high strength steels easier and cheaper. The combination of laminar and UFC technologies opens the way for new cooling schedules. Multiphase microstructures are therefore easily generated by controlling the intermediate temperature - between laminar cooling and UFC - and the coiling temperature.
