The invention relates to thermal treatment and may be used for hollow articles, such as pipes. Purpose of the invention-diffusion lu uniformity and intensity of cooling. Device has bath 1, in which is mounted a rotor 2 with gear wheels 4 and system of water supply, containing supply pipes and nozzle 7.8. Teeth of the adjacent gear wheels 4 are shifted over perimeter in one direction relative to each other. Tangent angle of displacement (turn) gear teeth is 0.0175-0.035 value real estate situated distance between adjacent wheels to their radius. Such displacement provides transportation of articles in bath 1 in initial period at angle 1-2 ?to horizon and fast removal from internal cavity of steam bubbles. 6 dwg. 0
