Brief Introduction to the Tracking and Delivery Control of Rolled Packaging Steel Strips
　　 The transportation of rolled products (steel billets, strips, strip steel) is one of the basic functions required by the production process. Its basic task is to control the speed of each section of the roller table and its turning and stopping, so that the rolling material can be transported at the fastest speed. The reheating furnace population is transported to the reheating furnace, rough rolling, finishing rolling, coiling, and processed in each area and then transported by the transportation chain. However, while ensuring the fastest transportation, it is necessary to ensure that the front and rear rolling pieces are not the same during automatic rolling. Collision, maintain a certain rhythm.
　　 In order to be able to transport and control the sequence of multiple rolling pieces on the production line (from the exit of the heating furnace to the transportation chain, there can be up to 7-8 rolling pieces) according to the process requirements, the basic automation controllers need to know each rolling piece The position on the rolling line and its position change, so rolling piece tracking is essentially an important procedure for coordinating various procedures and obtaining 'events'. The tracking of parts will be carried out separately in basic automation, process automation and production control levels, but the requirements of each level are different, and they are all based on the position tracking results of basic automation. Basic automated tracking is essentially to track the position and change of each rolling piece in the production line, and provide an 'event occurrence' signal for sequence control (the hot metal detector changing from OFF to ON or from ON to OFF is called a event). Basic automated location tracking results will automate the upload process.
　　 Process automation tracking is essentially to track the data of each rolling piece so that the data and rolling piece can be numbered, and the calculation and self-learning can be set correctly. At the same time, some 'events' are used to start some Input to the program.
　　 Production control level tracking will be used for quality control and report printing.
