METHOD FOR MANUFACTURE OF SEAMLESS WELDED RAILWAY WHEELS FROM CONTINUOUS INGOT Russian patent published in 1995 - IPC

Abstract RU 2049586 C1

FIELD: plastic working of metals. SUBSTANCE: method involves incomplete cutting of ingot and breaking it into billets in the ratio of SSS so that neck portions are defined; settling billets between upper and lower press slabs; forming; rolling wheels and stitching hub opening. Prior to settling billet is fixed on lower slab so that its longitudinal axis is in parallel with slab vertical axis. Prior to stitching hub opening web is formed on the basis of dependence recited in Specification. EFFECT: increased efficiency by reliable removal of metal portion with gas and nonmetallic inclusions from billet bodies during deformation. 3 cl, 3 dwg
