Abstract
In a method for quenching, particularly for steel tubes or similar, the tube (T) is quenched by a vortical flow of cooling liquid at least along the outer shell surface, with at least a circulatory motion inside the tube. The vortical flow of cooling liquid has a component of circulatory motion in the circumferential direction around the outer shell surface of the tube and a component of motion in the axial direction with respect to the tube. A device for the application of the method has a container (1) for the tube (T), with at least one source (18, 217) of supply of an external cooling liquid flow, and with an outlet (101) for the discharge of the flow from the container (1). The source (18, 217) of supply of the external cooling liquid flow is such that it generates the flow in a circumferential direction with respect to the tube (T). The discharge aperture (101) is provided at one end of the container (1) and its dimensions are such that they produce a component of the flow in the axial direction with respect to the tube (T) in the external cooling liquid flow.
