Orobtsev A. Development, research and mastering of technology of rolling-slitting in roughing groups of continuous wire mills by manufacture the wire-rod from billets of the increased section

The "know-how" of wire rod manufacturing on multi-strand wire rod rolling mills. Development and mastering of technology of rolling-slitting in continous roughing mill groups by wire rod manufacture from billets of the increased section. Comparative theoretical and experimental researches of wire rod rolling process and its quality on existing and developed technologies. Opportunity of increase the section of initial billet on multi-strand wire rod rolling mills - for the first time is shown at the expense of application of rolling-slitting process in roughing mill groups; is established, that the application of the new rolling circuit in roughing mill groups is accompanied by common reduction of energy consumption on rolling process; the parameters of working stands adjustment of the workers, ensuring stability of longitudinal rolled stock division and deformation in subsequent stands are developed; the comparative estimation of adaptability to manufacture of wire rod processing is given, at use existing and developed of the rolling circuits in roughing mill group, is established, that manufacture of a wire from obtained wire rod has no restrictions. The annual economy at new technology on ОАО "ЕМЗ" has made 700587,6 hrn. Continuous wire rod and light-section rolling mills.
