Abstract :
A basic automation system of online hardening in a die steel plant is introduced. It is based on Siemens S7-400 PLC and WinCC. The design of hardware and software is water-oriented due to the fact that a die steel pre hardened is very sensitive to water consumption and ratio. The control of plunger valves, electric valves, roller speed, water pressure and spray distance is adopted to make water be steady and precise. The practice in reality shows the water control meets the design requirements and hardening results are superior quality.
