Weather-proof and acid-proof steel wire rod for animal husbandry

Abstract

The embodiment of the invention provides a weather-resistant acid-resistant steel wire rod for animal husbandry, which comprises the following chemical components in percentage by weight: less than orequal to 0.07 wt% of C, less than or equal to 0.10 wt% of Si, 0.20-0.30 wt% of Mn, less than or equal to 0.025 wt% of P, less than or equal to 0.015 wt% of S, 0.15 to 0.20 wt% of nickel Ni, 0.62 to 0.75 wt% of chromium Cr, 0.25 to 0.32 wt% of copper Cu, 0.04 to 0.06 wt% of antimony Sb and the balance of Fe and inevitable trace elements.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and in particular relates to a weather-resistant and acid-resistant wire rod for animal husbandry. Background technique [0002] Breeding cages are widely used in animal husbandry, especially in specialized large-scale farms. At present, low-carbon steel hot-rolled round wire rods of Q195 are commonly used in China for processing. The production and processing technology is: φ6.5mm wire rod → mechanical shelling (or pickling)→rough drawing→finish drawing→φ1.85~3.0mm steel wire→straightening, shearing→welding into mesh→surface pickling→hot-dip galvanizing→air drying→grinding burrs→finished breeding cage. [0003] Due to the high humidity of the breeding environment and the contact with the weakly acidic poultry manure, the steel corrosion rate is fast, so the surface of the breeding cage needs to be treated with anticorrosion. At present, domestic breeding cage manufacturers mainl...

Problems solved by technology

[0005] The embodiment of the present invention provides a weather-resistant and acid-resistant wire rod for animal husbandry. By redesigning the chemical composition of the steel and finely controlling the steelmaking and rolling processes, the atmospheric corrosion resistance and acid resistance of the wire rod produced in the prior art are solved. The problem of poor corrosion, the produced wire rod also has the advantages of good drawing performance and strong resilience of steel wire.
