Abstract

The invention discloses a high-carbon steel wire rod low in network cementite precipitation and used for fine wire drawing and a production method of the high-carbon steel wire rod. The high-carbon steel wire rod comprises 0.79%-0.84% of C, 0.20%-0.40% of Si, 0.45%-0.55% of Mn, smaller than or equal to 0.010% of P, 0.0020%-0.010% of S, 0.0005%-0.00010% of Al, 0.0002%-0.0006% of Ti, 0.0015%-0.0025%of total oxygen and the balance Fe and inevitable impurities. The high-carbon steel wire rod is used for producing a fine steel wire with the diameter being 0.22 mm, the breaking rate of a produced steel wire cord thread is not larger than 3 times / ton, and the using requirement of a user is met.

Description

technical field [0001] The invention belongs to the technical field of iron and steel products, and in particular relates to a high-carbon steel wire rod with low mesh cementite precipitation and a production method thereof for filament drawing. Background technique [0002] As the market competition in the field of domestic metal products continues to intensify, manufacturers have continuously increased their requirements for the quality of raw materials for metal products. Especially for high-carbon steel wire rods used for filament drawing, the wire rod rolling process has a great influence on the structure of the wire rod and the properties of the drawn and processed products, so strict control is required. The reticular cementite in the wire rod structure is a brittle structure, which has an adverse effect on the wire breakage rate of the wire rod during the filament drawing process, and will deteriorate the fatigue life of the steel wire products such as thin steel rop...
