APPARATUS FOR COOLING OF ROLLED PRODUCT SHAPED PROFILES

FIELD: ferrous metallurgy, in particular, in-flow cooling of rolled product shaped profiles in rolling mill. SUBSTANCE: apparatus has casing composed of upper and lower parts with guiding channel defined between said parts and provided with drain openings, pipes having nozzles with axes arranged in single plane, and coolant supplying branch pipes. Metal body made in the form of prism is located longitudinally of and inside guiding channel, with one face of said prism being fixed on one of casing parts. Guides are arranged in parallel with free faces of prism. Pipes with nozzles are positioned opposite each face of prism so that axes of nozzles and rib are arranged in single plane extending through bisecting line of angle defined by faces adjoining to rib and on guides for movement transverse to longitudinal axis of apparatus. Through openings are formed in prism body and nozzles are eccentrically arranged therein. Casing is provided with flexible plate rigidly fixed on one of upper and lower parts of casing, free end of flexible plate being positioned in drain opening. Flexible plate rigidity may be adjusted. EFFECT: improved transportation of profile, reduced non-uniformity of properties across the entire section, and provision for carrying out simultaneous thermal straightening and thermal strengthening operations in rolling mill. 3 cl, 1 dwg
