The shape defects of wear-resistant plates, EN 10149-2 steel coil mainly refer to various waves and buckles existing in continuous rolling mill products. The main reasons are the unbalanced load distribution of the racks, poor tension settings between racks, and unreasonable work roll profiles. This kind of defect is easy to cause the adhesion phenomenon in the hood retreat, which has a great impact on the wear-resistant plates product quality. Edge defects are mainly caused by poor pickling trimming quality or poor plasticity of strip steel.

Application of EN 10149-2 steel coil stainless steel coil: 1. Automobile industry. As a structural material of automobile, stainless steel coil can not only greatly reduce the weight of vehicle, but also greatly improve the service life of automobile. 2. Water storage and transportation industry. The storage and transportation equipment based on stainless steel coil is recognized as the most sanitary, safest and most efficient water industry equipment. 3. The construction industry. The decorative panels of exterior walls and interior walls are generally made of stainless steel, which is not only durable, but also very beautiful.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This EN 10149-2 steel coil production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate EN 10149-2 steel coil size.
