Dust particles adhering to the corroded surface of stainless steel bars can accelerate corrosion. When dust particles are present on the surface, gaps form at the dust particle deposits, easily retaining a chlorinated ion-containing water film. This hinders oxygen replenishment, leading to the destruction of the passive film. Additionally, the dissolution zone forms a short-circuit battery with the passive zone near the dust particle deposits, exacerbating the formation and development of pitting corrosion.
Stainless steel round bar (stainless steel) is a shortened term for stainless steel, which is also known as acid-resistant steel, referring to steel that is corroded by chemical corrosive media (such as acids, alkalis, salts) rather than by weak corrosive media (such as internal gases, steam, water) or stainless steel itself. The applications of stainless steel round bar are extensive, widely used in hardware kitchenware, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace, construction decoration, equipment used in seawater, chemicals, dyes, papermaking, oxalic acid, fertilizers, and more. It is also used in photography, food industry, coastal facilities, ropes, CD rods, bolts, and nuts.
Stainless steel round bars are categorized into three production methods: hot rolled, forged, and cold drawn, primarily used for manufacturing mechanical parts or as billets for seamless steel tubes. Dust particles adhering to the corroded surface of stainless steel round bars can accelerate corrosion. When dust particles are present on the surface, gaps form at the dust particle deposits, which easily retain a chlorinated water film, blocking oxygen replenishment, leading to the destruction of the passive film. Additionally, this dissolution zone, combined with the passive zone near the dust particle deposits, forms a short-circuit battery, exacerbating the formation and development of pitting corrosion.
There are countless steel products in everyday life, steel is used in many places; stainless steel round steel is one type of steel used in producing steel products, and it has a wide range of applications. Stainless steel round steel belongs to both long steel and bar steel categories. By definition, stainless steel round steel refers to long steel with a uniformly round cross-section, typically about four meters in length. It can be divided into smooth bars and black bars. Smooth bars are characterized by their smooth surface, which is the result of precision rolling. On the other hand, black bars have a rough, dark surface and are produced through direct hot rolling.
In the automatic control system for the production of stainless steel round bars, the operational modes are becoming increasingly refined to cater to different operating environments and work objectives. The main categories are as follows:
1. Automatic Mode: Rolling steel is only possible in this mode, which is typically the standard condition for normal rolling production.
2. Simulated Operation Mode: Its primary purpose is to provide operators with a means to verify the normal operation of the various actuators such as the sleeve roller, shearing machine, etc., before rolling, as well as to ensure the correctness of the initial state and the absence of any abnormality in rolling control.
3. Side-by-Side Mode: In the side-by-side operation mode, it is possible to manually control certain equipment actions on-site, such as crawling, rotating shears, and changing rolls.
4. Maintenance Mode: The maintenance mode is not intended for rolling steel; it is solely for inspecting the equipment and its operational status, with the characteristic of minimal electrical and mechanical connections.
