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
The present invention relates to a kind of wire rod process of surface treatment.
Background technology
Wire rod is again wire rod, and wire rod is also wire rod, is often referred to into the minor diameter round steel of dish.The diameter of wire rod is (usually 6-9 millimeter) in the range of 5-19 millimeter, and its lower limit is the minimum dimension of hot-strip section.
In metallic article production process, due to the existence of wire rod scale on surface, affecting the follow-up drawing of steel wire, therefore removing iron scale is requisite important procedure during metallic article produces.
Wire rod complex manufacturing at present, not unified standard, the wire rod quality causing production is uneven, and a lot of operations that repeat also make under production efficiency, increases the work burden of workman, makes the competitiveness of product in market the highest simultaneously.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of wire rod process of surface treatment, and the method technique is simple, eliminates a lot of repeatability operation, improves work efficiency, and high treating effect.
For achieving the above object, the invention provides a kind of wire rod process of surface treatment, it is characterised in that comprise the steps: 1) pickling: density >=120, hydrochloric acid pond；
2) washing swings 2-3 time；
3) high pressure water washing: residual acid is washed down；
4) phosphatization: phosphating pond total acidity is 120-180 point, free acid 10-20 point, total zinc amount 40-60g/L, temperature is more than 65 DEG C, and phosphating time 2-10 divides；
5) high pressure water washing；
6) saponification: temperature >=85 DEG C, saponification pond, pH value >=8；
7) natural drying.
The invention has the beneficial effects as follows: the method technique of the present invention is simple, eliminate a lot of repeatability operation, improve work efficiency.
Detailed description of the invention
Technical scheme disclosed by the invention is a kind of wire rod process of surface treatment, it is characterised in that comprise the steps: 1) pickling: density >=120, hydrochloric acid pond；
2) washing swings 2-3 time；
3) high pressure water washing: residual acid is washed down；
4) phosphatization: phosphating pond total acidity is 120-180 point, free acid 10-20 point, total zinc amount 40-60g/L, temperature is more than 65 DEG C, and phosphating time 2-10 divides；
5) high pressure water washing；
6) saponification: temperature >=85 DEG C, saponification pond, pH value >=8；
7) natural drying.
The method technique is simple, eliminates a lot of repeatability operation, improves work efficiency.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
