High efficiency and energy-saving electrode control system
   

      All the time, steel-making is a kind of extensive industry of high consumption. However, fierce competition in global steel market compels steel-making to have absolute low cost, or it will be driven out of the market mercilessly.
  SEC electrode control system is originally brought from foreign company. Improved by our company, it becomes the latest digital electrode control system.
SEC electrode control system is basic on Germany Siemens automatic products of SIMATIC S7 400 series. It is used to all kinds of system and structure control. Compared with other products of other company, it is highly stable, in common use, and expandable. Besides, it reduces the cost of maintenance and spare parts. Compared with other company's products, the products of our company have the features as follow:
(1) Manual operation is preferred. It can be done needn't to close the automatic mode.
(2) Interlocking control has the function of creative hydraulic bypass valve, relief valve and proportional valve.
(3) It has the function of impedance value user-defined. Different heating curve can be chosen according to different heating process.
(4) Integration large capacity of alarming and reporting system can realize rapid diagnosis for system operation condition.
(5) The function of system parameter classification statistical can improve and control performance of system analysis actual situation.
(6) The function of impedance regulator ratio automatic dynamic adjustment can make sure excellent melting during the production process.
(7) Flexible way of parameter setting can set PLC program parameter on HMI directly. STEP 7 programming software and programming device are no need.
(8) Import Rogowski coil tests the secondary electrode current in real time. Detection accuracy is high. Real-time performance is high. There is no hysteresis effect and no heating. Installation is easy, stable and reliable.
(9) proven function of preventing electrode from breaking  
(10) powerful function of real and history trend
(11) the function of password protection of key parameter
(12) the function of transformer and reactance resistance plug protection
(13) the function of transformer and circuit breaker protection
