METHOD OF FLOW PRODUCTION OF SPRING STEEL ROD AND SUBSEQUENTLY WORKING IT

摘要

FIELD: metallurgical industry, namely, manufacture of rod of spring steels and subsequently working it. SUBSTANCE: method of flow production of rod comprises combined stages of continuously casting billet and rolling it at first in planetary rolling mill and then in bar rolling mill at normalized modes of all stages of said process. In the same flow line due to use of accumulated heat bent springy rail fastening member is made of received rod. EFFECT: enhanced efficiency. 4 cl, 1 dwg
