Stainless steel coil
is the product obtained after the steel plate is coiled. According to the production technology, it can be divided into cold rolled stainless steel coil
and hot rolled stainless steel coil
. According to the material, it can be divided into austenite, ferrite, martensite and duplex. Stainless steel coil. At present, the application of stainless steel coil is more and more extensive, and the market prospect is also more and more broad. First of all, the stainless steel coil has the following characteristics.
1. Corrosion resistance, beautiful appearance, can be used in decorations.
Second, the bending degree, toughness is good, can be curled into a ball.
3. It is convenient for transportation, and can be stacked into a ball after being rolled into a ball, saving space.
The processing of raw materials before making stainless steel pipes is also very important, and each process determines the quality of the pipe fittings. Today, we will show you the flattening and slitting process of stainless steel coils.
1. Stainless steel coil opening and leveling
When leaving the factory, stainless steel coils are mostly whole rolls, which are mainly used for easy transportation. In order to prevent the deformation of the steel coil after opening and leveling, it needs to be laid flat. If there are a lot of them, they can be separated by pads together. In addition, we should also pay attention to moisture. It will also deform once it gets wet. It can also be placed upright, but it cannot be placed for too long, and it will deform for a long time, unless the thickness of the floor is above 2.0mm.
2. Slitting of stainless steel coil
Stainless steel coils divide stainless steel strips of a certain width into one or several strips according to the specifications required by production. During the slitting process, problems such as scratches, curls, high edge burrs, insufficient width, collapse, side waves, and knife bends are easy to occur.
The problems of flattening and slitting of stainless steel coils directly affect the subsequent pipeline processes in serious cases. The produced stainless steel pipes have large size errors, rough surfaces, and non-straight pipes. If you want to buy high-quality stainless steel pipes, the manufacturer's raw material processing is also Very important.
