China is the world's largest steel producer, which means there are many steel plants in the country. Steel production is with high automation rate, involving hot rolling, cold rolling, winding, transmission. The production line of steel is tens of meters to hundreds of meters.
To ensure the quality of the production process, it is necessary to calibrate the machines in the production line every half year, such as rolling mill frame, elevation, width and so on. Because of the natural cause of land subsidence, an overall adjustment in sizes for levelness, parallelism, elevation, etc. in the automatic production line is required every two years. At present, WEDO provides services for SHAGANG GROUP, BAOSTEEL, VALIN GROUP, WEIQIAO and other well-known enterprises.
