This work concerns the application of a powerful cooling system to the continuous casting of steel. Such a system has two main benefits over conventional secondary cooling: - it provides a better support of the strand during casting : - it accelerates the metal solidification. This report concerns trials made in the laboratory and in the pilot plant. A first attempt at producing a water film by the flow of water through holes drilled in the sheath of the support rolls failed because of heterogeneous cooling. A second cooling technique was then tried: a water film flowing at high speed between the strand and a feeding box. The thickness of the water film varied from 1 to 4 mm. The experimental programme used to assess the cooling system includes the following: - building and optimisation of the cooling system; - hydraulic behaviour of the system; pressure distribution in the water film; measurement of the heat fluxes removed by the water film; - metallurgical behaviour of steel ingots undergoing the water film cooling.
