Abstract

The invention provides an artificial aging treatment method of high carbon steel wires. The method comprises the following steps that (1) the high carbon steel wires are stacked in a constant temperature furnace to be subjected to heat preservation, the heat preservation temperature is controlled to be 100 DEG C to 150 DEG C, and the holding time is controlled to be 50 min-200 min; (2) furnace cooling is carried out, the surface temperature of the high carbon steel wires during furnace discharging is 30 DEG C-40 DEG C, and the cooling time is controlled to be more than 30 min; and (3) naturalcooling is carried out to the room temperature, the room temperature is controlled to be 23+ / -5 DEG C. Compared with a traditional natural aging method, the plasticity value of hot rolling wire rods can be obtained by speeding up by 2 days to 11 days without deteriorating the plasticity.

Description

technical field

[0001] The present application relates to the technical field of aging treatment of high-carbon steel wire rods, and in particular, relates to an artificial aging treatment method of high-carbon steel wire rods. Background technique

[0002] High carbon steel wire is an important industrial wire material, including: spring steel, medium and high carbon steel, wire rod for rubber skeleton steel wire, steel strand wire rod, wire rod for bridge cables, alloy steel wire rod and non-woven wire rod for wire making Alloy wire rod, etc., the finished products after processing are widely used in the automobile industry, construction, machining and other industries. Wire rod is also called wire rod because it is delivered in coils.

[0003] The plasticity index of high-carbon steel hot-rolled wire rod has always been a difficult problem for high-end wire factories and deep-processing enterprises. The lamellar spacing is thick, which is mainly related to insufficient ...
