How to use lubricant to improve the drawing process of stainless steel?

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 common stainless steel wire drawing processes. Stainless steel wire drawing is the treatment of wire drawing effect on stainless steel and aluminum 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. 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 stainless steel wire drawing. So, what kind of lubricant can improve the process of stainless steel 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 the stainless steel is drawn, most of the wire surface needs special coating treatment. 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, and non-reactive coatings can respond well. Compared with the traditional oxalic acid coating, the non-reactive coating 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, the equipment investment is more Low, and the production process is more environmentally friendly; ③It has good moisture resistance; ④It can meet the needs of high-speed drawing.
