DEVELOPMENT OF THE INDUSTRIAL PRODUCTION TECHNOLOGY OF BARS AND WIRE STOCK MATERIALS FROM A WOLFRAMIUM. MESS.1. A FLOW DIAGRAM AND MODES OF RECEPTION OF WOLFRAMIC BARS

摘要

Are considered a flow diagram and modes of reception of wolframic bars. Is shown, that the application in a flow diagram of a helical rolling stock material by wolframic allow considerably to lower a fraction of a rejected material on lamination and on twisting. Are considered also microstructure of stock materials and influence of a mode of heat treatment on processes of a grain recovery and mechanical characteristics of stock material.
