The production process of cr coils hot rolled stainless steel coils

The raw material processing of stainless steel before pipe making is also very critical, and each process is a factor that determines the quality of pipe fittings. Today, I will take you to understand the flattening and slitting of cr coils hot rolled stainless steel coils.

1. Cr coils hot rolled stainless steel coils - flat

Most of the stainless steel coils leave the factory in whole rolls, which are mainly for the convenience of transportation; generally, when they are in the hands of the supplier, for the convenience of use, the stainless steel coils will be used with professional stainless steel flattening equipment, and the whole rolls of stainless steel coils will be cut. Kaiping, this process is called Kaiping; and the process of Kaiping is most prone to problems such as scratches and inaccurate lengths, so it is necessary to find a reliable manufacturer.

In order to prevent the cr coils hot rolled stainless steel coils from being deformed after they are flattened, they need to be laid flat, and a large number can be pressed together with a backing plate to separate them; Of course, it can also be placed upright, but it can't be placed for too long, and it will deform after a long time, unless it is a board with a thickness of 2.0mm or more.

2. Cr coils hot rolled stainless steel coils- slitting

Slitting of stainless steel coils is to separate a certain width of stainless steel strips into one or several stainless steel coils according to the specifications required by production. The process of slitting 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 cr coils hot rolled stainless steel coils, if serious, will directly affect the subsequent pipe making process, resulting in large size errors, rough surfaces, and insufficient straightness of the stainless steel pipes produced. .
