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 processing of cold heading steel (low, medium and high carbon steel), tool steel (50BV30, 6150, S2, etc.), and the processed material can efficiently meet the subsequent drawing and cold heading forming of various fasteners (steam parts, strong shrinkage parts, non-standard parts, aviation standard parts, etc.).
This process is mainly through the phosphorous saponification reaction, the phosphorous saponification film with excellent ductility and lubricity is formed on the surface of the wire, which is convenient for subsequent high-efficiency drawing and cold heading forming.
The main products are yx-715, yx-716, yx-600, yx-828 and yx-202 respectively.
Product features
(1) Environmental protection: there is no sediment in the phosphating process and no accelerator is needed.
(2) Energy saving: the phosphating temperature is low, ranging from room temperature to 50 ℃, reducing heating energy consumption.
(3) Strong adhesion of film: compared with traditional products, the film-forming speed is faster, the crystallization of the film is fine and dense, the adhesion of the film is greatly improved, and it is closely combined with the substrate. In the continuous drawing process, it can effectively protect the material from scratch, film noise and other abnormalities, and effectively improve the drawing speed.
(4) The tank liquid data is stable, the operation is simple, and the standardized operation is easy to be realized.
(5) The product has the advantages of long service life, low consumption of lubricant and protection liquid.

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.
