Embodiment Construction

[0014] The technical solution disclosed in the present invention is a wire rod surface treatment process, which is characterized in that it includes the following steps: 1) pickling: hydrochloric acid pool density ≥ 120;

[0015] 2) Wash and swing 2-3 times;

[0016] 3) High-pressure water washing: wash away the residual acid;

[0017] 4) Phosphating: The total acidity of the phosphating pool is 120-180 points, the free acid is 10-20 points, the total zinc content is 40-60g / L, the temperature is greater than 65°C, and the phosphating time is 2-10 minutes;

[0018] 5) High pressure water washing;

[0019] 6) Saponification: saponification tank temperature ≥ 85 ℃, PH value ≥ 8;

[0020] 7) Dry naturally.

[0021] The method has simple process, eliminates many repetitive processes, and improves work efficiency.

Abstract

The invention discloses a surface treatment process for a wire rod. The surface treatment process is characterized by comprising the following steps: 1) acid pickling, wherein the density of a hydrochloric acid pool is no less than 120; 2) water scrubbing and swinging twice to three times; 3) flushing with high pressure water so as to totally remove residual acid; 4) phosphatization, wherein the total acidity of a phosphatization pool is 120 to 180 points, free acid is 10 to 20 points, total zinc amount is 40 to 60 g / L, temperature is greater than 65 DEG C, and phosphatization time is 2 to 10 min; 5) flushing with high pressure water; 6) saponification, wherein the temperature and pH value of a saponification pool is no less than 85 DEG C and 8 respectively; and 7) natural drying. The process provided by the invention is simple, omits a plurality of repeated procedures and improves work efficiency.

Description

technical field [0001] The invention relates to a wire rod surface treatment process. Background technique [0002] Wire rod is also called wire rod, and wire rod is also called wire rod, which usually refers to small-diameter round steel in a coil. The diameter of the wire rod is in the range of 5-19mm (usually 6-9mm), and the lower limit is the minimum size of the hot-rolled steel section. [0003] In the production process of metal products, due to the existence of scale on the surface of wire rods, the subsequent drawing of steel wires is affected, so removing scale is an essential and important process in the production of metal products. [0004] At present, the wire rod production process is complex and there is no unified standard, resulting in uneven quality of the produced wire rod. Many repeated processes also make the production efficiency low, increase the labor burden of workers, and make the market competitiveness of the product is not high. Contents of the...
