Seamless steel tubes for the design research background, with WinCC step to complete the furnace and the cooling bed of the host computer monitor, walking-beam furnace has heated billet speed, capacity, and temperature uniformity, burning less steel heating quality, operational flexibility and can be sent stepping steel, step-by-step advance and retreat, such as steel and the advantages of operating time, step cooling bed also has a cooling temperature uniformity, productivity, and the advantages of flexible operation, the furnace and the cooling bed is a step todays widely used in steel mills, an advanced furnace. WinCC running on the personal computer environment, with a wide range of automation equipment and control software integration, the project has a wealth of settings, video windows and menu options, the use of flexible, full-featured, in order to provide the operator with the aid of diagrams, the operation of visual image. WinCC can easily with a wide range of software and user program together to build a friendly human-machine interface to meet the ac
