Embodiment Construction
[0021] The specific embodiment of the present invention will be further described below in conjunction with embodiment:
[0022] A wire rod for ultra-high conductive steel wire, the chemical composition wt% of which is: C: 0.002% to 0.009%, Si: 0.004% to 0.009%, Mn: 0.02% to 0.08%, P≤0.015%, S≤0.010% , All aluminum: 0.0025% ~ 0.0040%, total oxygen: 0.0040% ~ 0.0060%, the rest is iron and unavoidable impurities.
[0023] A production process for a wire rod for an ultra-high conductive steel wire, comprising the steps of:
[0024] 1) Smelting: The wire rod is produced by converter-LF furnace-RH-continuous casting process; after RH refining, the molten steel is left to stand for 10-20 minutes; the inclusions in the steel are promoted to float up and the molten steel is discharged, and the size of the inclusions in the wire rod is reduced.
[0025] 2) Wire rod rolling temperature: the pre-finish rolling temperature of the rolled piece is controlled at 960°C-980°C, the finish-roll...

Abstract
The invention discloses a wire rod for an ultrahigh-conductivity steel wire and a production technology thereof. The wire rod comprises the chemical components of, by weight, 0.002-0.009% of C, 0.004-0.009% of Si, 0.02-0.08% of Mn, 0-0.015% of P, 0-0.010% of S, 0.0025-0.0040% of total aluminum, 0.0040-0.0060% of total oxygen, and the balance Fe and inevitable impurities. Compared with the prior art, the wire rod for the ultrahigh-conductivity steel wire and the production technology thereof have the beneficial effects that the oxide inclusion size of the wire rod produced through the technology is not larger than 25 [mu]m, the wire breaking rate in the wire rod machining process is not larger than 2 times per ton, the conductivity reaches 16% IACS, the wire rod can partially replace commoncopper conductive materials, and the purpose of reducing the production cost is achieved.
Description
technical field [0001] The invention relates to a wire product, in particular to a wire rod for an ultra-high conductive steel wire and a production process thereof. Background technique [0002] With the rapid development of my country's industry, the demand for conductive materials continues to increase. Although the general copper conductive material has good conductivity, it is expensive, which brings difficulties for large-scale application. Developing a conductive material with relatively low cost to replace copper conductive material and apply it in industrial production has broad market value and application value. In the development process of wire rod for ultra-low carbon conductive wire, inclusion control technology is very important. On the one hand, the inclusions affect the cold working performance of the wire rod. The larger the size and the more the number of inclusions in the wire rod, the wire rod will be broken during the drawing process; on the other ha...
