Finishing
As finishing (from French ajuster = adjust = to adjust something, make it even, put in order), sometimes also a finishing shop , there are processing steps in a steel or rolling mill for finishing the products.
The processes used can vary depending on the manufacturing process, the material, the subsequent processing and the respective purpose. The finishing department following the steel or rolling mill is also often mentioned.
Processing aisles and procedures in the finishing shop
- To achieve the required final dimensions, depending on the dimensions and material, different cutting processes such as mechanical cutting , oxy-fuel cutting , plasma cutting or laser cutting can be used.
- Often an edge processing is already carried out on the product through the required cutting process. If it is necessary for technological reasons, this operation can also only be carried out afterwards using further thermal separation processes.
- Clear identification of the product by signing with color or stamps.
- Removal of surface imperfections by grinding or removing affected areas.
- The samples required for quality control can also be cut in the finishing shop. These specimens are used for material tests such as tensile tests , notched bar impact tests and various hardness tests.
- For final processing, a surface treatment can be carried out in the finishing line using various processes such as pickling , blasting and grinding .
- In order to achieve the required degree or flatness of the end product, it can be straightened .
