METHOD OF MAKING CALIBRATED ROLLED STOCK FOR FORGING PARTS OF CONSTRUCTION STEELS Russian patent published in 1994 - IPC

Abstract RU 2014917 C1

FIELD: metal pressure forming. SUBSTANCE: method of producing calibrated rolled stock, mainly of steels, for hot and cold forging comprises steps of heating a blank, rolling it and cooling with subsequent annealing, further cold deformation of it with percentage reduction value, equal to 4-11% , at ratio of Mn/S in the steel, being rolled, consisting 45-150. EFFECT: elimination of burrs on end surfaces of rods at cold cutting of them and stable mechanical properties in cross sections along the rod. 1 cl, 5 tbl
