METHOD OF MAKING REINFORCEMENT STEEL FOR DIE- ROLLED SECTIONS Russian patent published in 2004 - IPC

FIELD: metallurgy; making reinforcement steel by use of cold deformation for application of die-rolled sections. SUBSTANCE: proposed method includes cold deformation of hot-rolled blank at simultaneous application of die-rolled section. Relative elongation of hot-rolled blank equal to 1.4-2.4 of relative elongation of reinforcement of die-rolled section. Application of die-rolled section is performed at relative cogging whose magnitude is found from expression given in Specification. EFFECT: high predicted level of ductility and strength characteristics; improved quality of product. 1 ex
