Description
Изобретение относитс к области металлургии, а более конкретно к заготовкам дл производства высокопрочной стальной проволоки.The invention relates to the field of metallurgy, and more specifically to blanks for the production of high-strength steel wire.
Известна заготовка дл получени высокопрочной стальной проволоки, изготовленна из углеродистой качественной конструкционной стали по ГОСТ 1050-74 с содержанием углерода 0,50-0,80% 1, .Known billet to obtain high-strength steel wire made of high quality carbon structural steel according to GOST 1050-74 with a carbon content of 0.50-0.80% 1,.
Однако при получении из нее проволоки малых диаметров данна заготовка имеет высокую обрывность из-за повышенного содержани неметаллических включений, примесей цветных металлов и из-за неоднородной струкTyiMii металла по поперечному сечению заготовки.However, when small wire diameters are obtained from it, this preform has a high breakage due to the high content of non-metallic inclusions, non-ferrous metal impurities, and due to the heterogeneous structure of the metal TyiMii over the cross section of the preform.
Наиболее близким к предлагаемой по технической сущности и достигаемому результату вл етс заготовка дл получени стальной проволоки малого диаметра, вьртолненна из высокоуглеродистой стали эвтектоидного состава при содержании углерода 0,70-0,74% и пониженном содержании меди, никел , хрома, фосфора, серы С2 .The closest to the proposed technical essence and the achieved result is a billet for the production of small diameter steel wire, made of high carbon steel of eutectoid composition with a carbon content of 0.70-0.74% and a reduced content of copper, nickel, chromium, phosphorus, sulfur C2 .
Однако при кристаллизации стали в изложнице в ней развиваютс про-.However, during the crystallization of steel in the mold, it develops pro-.
цессы ликвации, привод щне к повьваению содержани неметаллических включений в осевой зоне заголовки. Этоprocesses of segregation, leading to the growth of the content of non-metallic inclusions in the axial zone of the headers. it
с приводит к тому, что центральна осева зона заготовки имеет пониженную пластичность по сравнению с остальными участками заготовки, обуславливающую повышение обрывности в цессе волочени из-за зарождени c leads to the fact that the central axial zone of the workpiece has a reduced plasticity compared with the other parts of the workpiece, causing an increase in breakage in the process of drawing due to the origin
трещин в осевой зоне заготовки. Повышенна обрывность снижает техникозконсдаичехзкие показатели процесса волочени , приводит к отбраковке проволоки на промежуточных этапахcracks in the axial zone of the workpiece. Increased breakage reduces tehnikozkonsdaichehzkie performance of the process of drawing, leads to the rejection of the wire at intermediate stages
5 процесса и увеличивает потери метгшла .. 5 process and increases the loss of metal.
, Цель изобретени - уменьшение обрывности при изготовлении проволокиThe purpose of the invention is to reduce breakage in the manufacture of wire.

Эта цель достигаетс тем что в заготовке дл волочени , выполненной из высокоуглеродистой стали звтектоидного состава, заготовка выполИена составной по сечению, причем ее This goal is achieved by the fact that in a blank for drawing, made of high-carbon steel with a tectoidal composition, the blank is made composite over the section, and its
