The present paper is concerned with a predictable model for the temperature change of a horizontally moving hot steel plate cooled by a laminar water curtain. The numerical results calculated by the model presented here give a fairly close agreement with the results of cooling test.The effect of the traveling velocity of the hot plate on the cooling intensity has been examined from a numerical as well as experimental point of view. It has been found that the film boiling occurs even on the water impinging surface beyond a certain traveling velocity, and therefore the cooling intensity is decreased to an appreciable degree. It has been suggested from such facts that there is a critical velocity determining whether the film boiling occurs or not.
