1. A method of cooling a continuously cast strand, particularly a steel strand, in a secondary cooling zone of a continuous casting plant, comprising the steps of arranging a spray nozzle at the region of at least two consecutively spaced guiding means for guiding the cast strand along a predetermined path of travel, moving the cast strand along said predetermined path of travel defined by said guiding means, feeding coolant into the nozzle to flow initially essentially in the axial extent thereof and then to depart therefrom in a direction extending transversely with respect to the axial flow of the coolant through the nozzle to thereby form a spray pattern of coolant, directing the spray pattern of coolant towards the surface of the cast strand to impinge thereat along an impingement area extending substantially transversely across the surface of the cast strand, producing a distribution of coolant at the impingement area of the strand which is substantially uniform at least over the major portion of the transverse width dimension thereof, said major portion of the transverse width dimension amounting to at least about 60 percent of said transverse width dimension of the strand, and substantially uniformly cooling the cast strand across its transverse width dimension by means of the impinging spray pattern of coolant.
