The Secret of the Stainless Wire Drawing Process
For stainless steel products, in order to reflect the texture of metal materials and make the surface of metal products smooth and beautiful, many companies will carry out some special surface treatments, such as the common stainless wire drawing process. Stainless wire drawing is a treatment for the wire drawing effect of stainless steel products. It has become a very popular surface treatment technology.
Since it is an industrial processing technology, it will inevitably use lubricants. In the process of metal drawing and deformation, because the surface of stainless steel is smooth and low in roughness, lubrication is more difficult, and the requirements for lubricants are also higher. We can see that the performance of the lubricant directly determines the quality of the stainless steel and the surface finish, which is the key to the quality of the stainless wire drawing.
So, what kind of lubricant can improve the process of stainless wire drawing?
Wire drawing processing is usually divided into oily wire drawing and dry wire drawing. Therefore, the lubricants used in them are also divided into two types: oily and dry. Generally speaking, filaments with a diameter of less than 0.1mm in the final product need to be annealed once or twice. If it is a steel wire with a diameter of less than 0.21mm, it is drawn with an oil-based lubricant, and the mold can be a synthetic diamond mold or a natural diamond mold. In the large-diameter steel wire drawing, we generally use ordinary tungsten steel dies.
It is worth noting that before stainless steel is drawn, most of the wire surface needs to be specially coated. This is mainly to increase the surface roughness and improve the carrying capacity of soap powder, thereby solving the problem of the surface of stainless steel being too smooth. Compared with the traditional oxalate treatment, more non-reactive coatings are currently used, and the coated wire rods generally use calcium-based wire drawing powder when they are drawn for the first time. Coupled with the storage requirements during the production process, high requirements are also placed on its moisture resistance. CONDAT’s VICAFILTS series of non-reactive coatings can respond well.
Compared with the traditional oxalic acid coating, the VICAFILTS series has four main advantages: ①The surface coating is even, and it has good adhesion and the ability to carry soap powder; ②In a shorter processing time, lower equipment investment, and at the same time The production process is also more environmentally friendly; ③It has good moisture resistance; ④It can meet the needs of a high-speed drawing.
