Abstract: An apparatus for quenching a heated metal plate moving and restrained in a plane has upper and lower rolls which engage the top and bottom surfaces of the plate. Jets of quench fluid are located between the rolls and direct quench fluid onto the top and bottom surfaces of the plate in the direction of travel of the plate. A tank member is positioned underneath and surrounding the bottom rolls for maintaining the level of quenching fluid so that the plate conveyed on the lower rolls will have its bottom surface continuously swept with high velocity turbulent fluid.

Abstract: A pipe is heated with its longitudinal axis positioned vertically and then lowered from a furnace. As the pipe emerges from the furnace, it engages an inner ring of rollers and an outer ring of rollers which press against the hot pipe to shape it into a round configuration and to restrain the pipe during the initial impingement of quench fluid. As the pipe continues downward it is quenched by impinging the inside and outside surfaces with converging cones of high intensity quench liquid forming impingement rings on the inner and outer surfaces of the pipe which are opposite. The cooling by application of additional fluid and restraint by rings of rollers are continued after passage through the high intensity zone until the pipe reaches ambient temperature.
