More Information
Summary:metallurgy, namely rapid cooling of elongated rolled stock. SUBSTANCE: pumping jet unit includes housing with branch pipe for supplying cooling agent, receiving and discharging funnels, inlet guide having outer cone outlet portion and mounted in housing with possibility of motion along its lengthwise axis, nozzle forming member mounted coaxially relative to inlet guide with possibility of motion and fixation relative to lengthwise axis of housing. Inner surface of outlet funnel has two cone portions joined by cylindrical portion at relation of angle of generatrix of first cone portion to angle of generatrix of second cone portion equal to 1.2-4.5. Outlet funnel is mounted in such a way that slit nozzle is formed by its inner surface, outer cone portions of inlet guide and nozzle forming member. EFFECT: possibility for regulating profile of nozzle and therefore controlling relation of drawing and braking forces of flow of cooling agent. 1 dwg
