Mos'pan N. Theoretical and Experimental Bases of Frequentative Wire Drawing Routes Intensification at Presence of Steel Low-carbon Wire Twisting

The influence of geometrical parameters of wire drawing mills, which work without sliding and with the accumulation of wire on drumsrigs, wire removal from a traction drum and mills kinematics on the twisting degree deformation of metal was the first defined theoretically. The regularities of influence of cyclic unidirectional and multidirectional twisting loading on mechanical properties of steel low-carbon wire were defined experimentally. The ranges of wire removal heights from a drum to a friction roller while the "rude-middle" and "thin" wire drawing, which provides possibility of multidirectional deformation of wire twisting were the first defined theoretically. The projecting method of routes of the multiple wire drawing at presence of multidirectional metal twisting and wire drawing speed was developmented. The rational working features of revolving drawing dies in the line of wire drawing mill were the first defined for providing of the multidirectional metal twisting . The research results are presented as Technical Propositions for metalware enterprises PE "AORIST" and LTD "NT Steel" (Dnepropetrovsk) and has been accepted for use. Results of this work are also used in the course of studies in National Metallurgical Academy of Ukraine.
