Parusov E. V., Sychkov A. B., Gubenko S. I., Sahura L.V. On improving technological plasticity at drawing rolled steel products of high-carbon steel without heat treatment
Abstract
The comprehensive analysis of various factors (structural and process), reducing the technological plasticity rolled steels of high-carbon steel at drawing is completed. To ensure hitless drawing pearlite class steels with a deformation degree of not less than 75%, rolled steels diameter of 8.0...14.0 mm must have a certain set of quality indicators: uniformly formed sorbitol structure on the cross section of the metal, minimum pollution has become non-metallic inclusions, absence or the presence of cementite grid no more class B (NFA 04-114:1984). Studies have shown that martensite, non-metallic inclusions and areas of perlite more than 5 points (GOST 8233-56) are additional stress concentrators and cause premature failure of metal at drawing. Negative effects of additional factors, such as mechanical damage and exceeding metal drawing speed regulation on the formation of unacceptable structures (martensite) at rolled steels-wire surface it is established. The research allowed to develop innovative new modes of deformation and heat treatment rolled steel high carbon steel. This allowed along with rationally selected chemical composition of steel to reduce liquation manifestations, provide high technological plasticity of the metal during drawing and to achieve the required strength class finished products without any additional input in the steel alloying elements. Keywords: rolled steel, chemical composition, microstructure, process flexibility, non-metallic inclusions, perlite, marten-site.References
