Fast Cooling

To implement the new generation thermo mechanical control process (NG-TMCP), the automatic control system of ultra fast cooling (UFC) was developed by combined with the renovation project of controlled cooling system in one plate production line. This system was composed of basic automation subsystem and process automation subsystem. As the main control unit of the basic automatic control system, a S7400 PLC system is used to control the UFC device and to achieve the chain control between the UFC system and the mill system. While the process control system is to realize the automatical setting of the cooling schedule by the developed finite element temperature field model and the temperature homogeneity model. The industry application shows that the NG-TMCP which is based on the UFC can reduce the alloy content effectively and implement the low-cost reduction produce of high-grade products.

Lab Test

Based on the control process and requirements of the industrialized recirculating aquaculture system (IRAS), we designed an aquaculture automatic control system. The entire system is divided into seven modules including water circulation and filtration, bioreactor self-loop, water quality monitoring, Emergency treatment, thermostatic temperature control, PID operation, and failure alarm. It is used to control the water circulation, and automatically detect and adjust the environmental factors of the pond for best farming environment. The lower computer adopts Siemens S7-200 PLC. MCGS configuration software is applied in the upper computer for the dynamic display, parameter setting, fault alarm and other functions of the whole recirculating aquaculture process. The lab test showed the advantages of the system including the high degree of automation of the system, user-friendly, easy to maintain and reliable operation, with a good promotional and application value.
