The Effect of the Deformation Method of the Billets on Mechanical Properties of Molybdenum Bars and Wire

Abstract

A procedure has been developed for calculating the geometric, kinematic and energy-power parameters of helical rolling, which allows a comparative analysis of the processes carried out in stands of various designs. Based on the results of this analysis, a helical rolling mill was designed and manufactured which allows to roll materials with high deformation resistance at high temperatures. The results of the study of the mechanical characteristics of molybdenum bars and wires made by new technology are presented.

Method for Calculating the Shape of Rolls for Helical Rolling

“…Recently, the development of different industry sectors [1][2][3][4][5][6][7][8][9][10][11] requires the solution of various technological production problems [12][13][14][15][16][17][18][19][20][21][22] and also increases the requirements for the efficiency and quality of production technologies [23][24][25][26][27][28][29][30]. One of the most promising and profitable methods to produce high-quality seamless pipes and rods is helical rolling.…”
