Product overview
This process belongs to phosphating process, serving the special field of cold plastic processing of iron and steel materials. It is suitable for the treatment of cold heading steel (6a, 08Al, 15a, 22a, 10B21, 35K, 45k, 40Cr, SCM435, scm440, etc.) and tool steel (50BV30, 6150, S2, etc.), The phosphorous saponified film with excellent ductility and lubricity is formed on the surface of the wire, which can effectively meet the cold heading forming of various kinds of large deformation fasteners (such as strong shrinkage parts, non-standard parts, automobile parts, aviation standard parts, etc.).
The main products are yx-628, yx-638, yx-600, yx-828 and yx-202 respectively.
Product features
(1) Environmental protection and energy saving: compared with similar products in the market, the amount of phosphate sediment is reduced by more than 50%. The sediment is not easy to solidify and adsorb on the heating equipment, which is easy to clean up and save heating energy consumption.
(2) Low product consumption: compared with the market products, the product consumption is reduced by about 30%.
(3) The phosphating coating has fine crystal and good compactness, which can reduce the die loss of subsequent drawing and cold heading by more than 50%, and reduce the die cost.
(4) The operation is simple, the stability of tank liquid is excellent, and it is easy to realize the data-based standard control.
(5) The results show that the grease content of yx-828 lubricant is nearly twice as high as that of traditional products, the durability of bath liquid is strong, and the period of changing groove is prolonged by more than 3 times; moreover, the surface of treated wire rod is clean without dust and does not pollute cold heading oil.

Process introduction
1、Overview of phosphating
Phosphating belongs to the pretreatment process of metal surface. Yingxing's phosphating products focus on the field of cold plastic deformation processing.
First of all, the metal enters the phosphoric acid tank after a series of processes of acid pickling and water washing. In the phosphoric acid tank, the surface of the metal reacts with phosphate to form a phosphating film which is insoluble or insoluble in water. Then through the subsequent saponification reaction, a protective film with good ductility and lubricity is formed on the metal surface.
The main function of phosphating film is to improve the cold plastic deformation processing ability of the material, so that it can effectively carry out subsequent drawing and cold heading forming, and produce qualified metal products such as fasteners, auto parts, strong shrinkage parts and standard parts.
2. Process flow
Pickling → pickling → pickling → washing with high pressure water → washing → washing → activation → phosphating → washing → saponification
3. Process characteristics
3.1 quantify various parameters in the process, including pH value and conductivity of water, iron ion and concentration of hydrochloric acid, total acidity and free acidity of phosphating tank, temperature and accelerator, alkalinity, temperature, sugar content and oil content of saponification tank.
3.2 timely monitor data and implement scientific data management to ensure product quality.
