The process control system based on LabVIEW in a hardening die steel production line

This article discusses the design of a process control system for a hardening production line of die steel in a steel plant in China under the LabVIEW. This design achieved the functions including information reception of the steel billet, setting of process, real-time data acquisition, data storage, device status monitoring and model optimization. The practical application in reality shows and proves that the system runs steadily with complete functions and it assures the production of hardening die steel with high quality.
