Quality Control of the Rolling Line:
This section includes rolling lines of branch and coil rebars in which the inspectors of the quality control inspect the entered bars (including the produced bars and the bars imported to the factory) to be used in the production line after confirmation. In this stage, the imported bars are inspected in regard to technical documents and they are analyzed and sampled to be correspondent to the request. Also, during the production procedure, the quality control inspectors are always present in the production line and control both the production procedure and the products to be in line with the related standards. They select samples from the products and send them to laboratory to perform mechanical, metallographic, and chemical tests on them. In the case that product corresponds to the standards, it is delivered to the storehouse, if not, the production unit is informed of the case and a decision is made about the nonconforming product in that if it could be classified in another group, this classification is carried out; otherwise, it is delivered to the waste storage to be used in the steelmaking unit as scrap metal.
