Flattening and slitting process of stainless steel coil

The raw material processing of stainless steel coil before pipe making is also very critical, and every process is a factor that determines the quality of pipe fittings. Today, I will take you to learn about the flattening and slitting process of stainless steel coil panels.

1. Kaiping the stainless steel coil plate

Most of the stainless steel coil plates are made in full rolls when they leave the factory, mainly for the convenience of transportation; generally, when they are in the hands of the supplier, they will use professional stainless steel flattening equipment to flatten the entire roll of stainless steel coils. Kaiping, this process is called Kaiping; and the Kaiping process is most prone to problems such as scratches and insufficient length.

In order to prevent the stainless steel coil plate from deforming after opening, it is best to lay it flat. If the number is large, it can be pressed together and separated by a backing plate. Also, pay attention to moisture prevention, as it will deform once it gets wet. Of course, it can also be placed upright, but the time can not be too long, it will be deformed after a long time, unless it is a board with a thickness of 2.0mm or more.

2. Slitting of stainless steel coil plate

The slitting of a stainless steel coil plate is to divide a certain width of stainless steel strip into one or several stainless steel coil strips according to the specifications required by the production. The slitting process is prone to problems such as scratches, uneven rolls, high edge burrs, insufficient width, collapsed rolls, edge waves, and knife bends.

The problems that occur in the flattening and slitting of the stainless steel coil plate, if they are serious, will directly affect the subsequent pipe-making process, resulting in large dimensional errors, rough surfaces, and insufficient straightness of the stainless steel pipes produced; so If you want to purchase high-quality stainless steel pipes, the raw material processing of the manufacturer is also very important. The stainless steel raw materials of large stainless steel coil manufacturers all use large cold-rolled sheets produced by large factories. They have large factories and advanced production equipment to ensure that every A stainless steel coil product maintains a high quality when it leaves the factory.
