The Ultra Dry Cooling project objective is to validate and facilitate the industrial transfer of a rupture technology. This technology is a new steel strip cooling method that offers very high cooling rates, while in the same time being inert for the strip, to enable metallic coating directly after cooling. The basic principle of Ultra Dry Cooling is to spray a liquid hydrocarbon on the hot strip, a part of the hydrocarbon being vaporized at the contact between droplets and the steel surface. The liquid and vapor phases are recovered in a closed loop. Several key steps have been defined to secure the industrialization. It includes at first the establishment of experimental correlation of heat transfer on a laboratory test bench. Then a complete safety study has been conducted to secure the industrial design. An Endless Strip Bench has been built and commissioned based on this design, and tests have been undertaken for pentane and then hayeptane as cooling fluid, after modification of the bench. Good behavior and high cooling performances have been demonstrated on the bench with heptane as a cooling fluid. The last part of the project focused on the basic engineering of the industrial design of the system using heptane, and on a deep study of steel surface quality after being cooled down by heptane. Conclusions are very encouraging, as an industrial solution has been determined, cooling performance and surface quality demonstrated. Finally, potential applications of the technology have been highlighted through contacts with main steelmakers.
