Stainless steel wire rod after pretreatment before rolling pickling stainless steel wire, stainless steel wire and the collective oxide surface with a solid stainless steel wire Shengyuan affordable, difficult to remove, if the direct pickling, the effect is not very good, so it can start with a Pretreatment measures, then the use of an oxidant, activator mixed acid cleaning can be more effective removal of stainless steel oxide. Stainless steel wire commonly used pretreatment method in two ways: alkali leaching and blasting. 1, alkaline leaching alkaline leaching is that the wire was immersed in molten salt or an alkaline solution to change the scale of the structure. Alkaline leaching can be divided into saline soaked melt and alkali leaching solution. Stainless steel by melting saline soaked surface from damage, pickling metal loss is relatively small, can greatly shorten the pickling time, increase productivity, but to remain at a high temperature molten salt, the energy consumption of stainless steel wire service good source of Goldman Sachs, Another disadvantage is the need to melt saline soaked set up a special base slot, long slot bases warming cycle, energy consumption. Some do not yield, not continuous multi-use solution for manufacturers alkali leaching process. Alkaline leaching solution and melt saline soaked same principle, but with a temperature below the boiling point of the solution, corresponding to a long time and asked alkali leaching. With an alkaline aqueous solution of potassium permanganate (a temperature of about 100 ℃) immersion despite save energy, but low productivity, only as a complement. Stainless steel wire in production processes in magnetism it! People often think of stainless steel wire rod magnets verify its quality and authenticity Shengyuan stainless steel wire with a very good, do not smoke no magnetic, considered a good, worthy of the name; suck the magnetic Shengyuan stainless steel wire, it is considered counterfeit, fake goods. In fact, this is an extremely one-sided, fault distinguishing way. Reality stainless steel wire will "rust", will also take magnetic stainless steel wire is more than 60% of the iron matrix, participate networks, nickel, molybdenum and other alloying elements of high-alloy steel, its greatest feature is resistant to strong, but not definitely not rust stainless steel wire. In coastal areas or some serious local air pollution, while large chlorine ion content in the air, exposure to the atmosphere of stainless steel wire appearance can have some rust, but rust confined to the outer, not erode stainless steel wire inside the matrix . Many varieties of stainless steel wire, most with a magnetic, therefore, is not to identify with the magnet adsorption scientific way stainless steel lines. Variety of complex stainless steel wire, according to lay out at room temperature can be divided into the following categories: 1 austenitic: If 304,321,316,310, etc; 2 martensite or ferrite: If 430, 420, 410, etc; Shengyuan stainless steel wire handy, Shengyuan stainless steel, stainless steel wire Ltd.
