Stainless steel processing refers to stainless steel with stainless steel shear, folding, bending and other properties, the industrial production of welding and other mechanical processing and final stainless steel products requires a large number of machine tools, equipment, stainless steel processing equipment in the process of stainless steel processing.
The classification of stainless steel processing equipment is divided into cutting equipment and surface treatment equipment, and cutting equipment is divided into open groups.
In addition, from the thickness of stainless steel to the point, there are cold hot rolling processing equipment points.
Hot cutting equipment mainly includes plasma cutting, laser cutting, water cutting, etc.
From stainless steel products, it is generally divided into stainless steel seamless steel pipe and stainless steel welded pipe.
Original surface: No. 1 Hot-
Rolled surface after heat treatment and pickling.
Generally used for cold
Rolling materials, industrial tanks, chemical plants, etc. , thick 2. 0MM-8. 0MM.
Blunt face: None
After heat treatment and pickling, the 2D is cold, the material is softer, and the surface is silver and white. it is used for deep processing of auto parts and water pipes. Matte: NO.
After cold rolling 2B, the surface is treated by heat treatment and pickling, and then the surface is polished to make the surface bright.
Easy re-machining due to smooth surface
Grinding, make the surface brighter, widely used, such as tableware, building materials, etc.
With the improvement of surface finish of mechanical properties, almost all applications are satisfied.
Coarse sand: No. 3 with 100-
120 grinding Belt grinding products.
With a better gloss and a rough pattern that is not continuous.
It is used for interior and exterior decoration materials, electrical products, kitchen equipment, etc. Fine sand: NO.
4 grinding products with a particle size of 150-180.
The gloss is better, the texture is not continuous, and the stripes are better than none. 3 fine.
It is used for bathing, decoration materials inside and outside the building, electrical products, kitchen equipment, food equipment, etc.
Bright: BA undergo bright annealing after cold rolling and pass through flat products.
Excellent surface gloss, high reflectivity.
Like a mirror.
Used for household appliances, mirrors, kitchen equipment, decorative materials, etc.
In the field of building application, the surface treatment of stainless steel is very important for many reasons.
The corrosion environment requires a smooth surface because the surface is smooth and it is easy to produce scale.
The deposition of dirt can cause rust and even corrosion of stainless steel.
In the spacious hall, stainless steel is the most commonly used material for elevator decorative boards. Although the surface of fingerprints can be wiped away, it affects the appearance, so it is best to use the appropriate surface to prevent fingerprints from being left.
Sanitary conditions are important for many industries such as food processing, catering, brewing, and chemical industry.
In these applications, the surface must be easily cleaned using a chemical cleaner every day.
Stainless steel is the best material in this field, in public places, the surface of stainless steel is often harmful, but an important feature of it is the ability to clean up, this is a remarkable feature of stainless steel than aluminum.
The surface of aluminum is easy to leave traces, often difficult to remove.
Clean the stainless steel surface should be cleaned along the stainless steel line, because some surface processing lines are one-way.
Stainless steel is most suitable for hospitals or other areas with good sanitary conditions, such as food processing, catering, brewing, chemical industry, etc. , not only because of the convenience of daily cleaning, but also the use of chemical cleaners, but also because the bacteria are not easy to reproduce, the test shows that the properties of stainless steel in this regard are the same as that of glass and ceramics.
