Research on Level-2-Computer control system for heat-furnace in plate heat treatment line

In this paper, a new Level-2-Computer control system is developed for heat-furnace in plate steel heat treatment line. The process layout, Level-2-Computer control system, network Structure for Level-2, software development environment, and some important calculation formulas for mathematical model for heat-furnace, have been represented, as well as the flow chart of main program for mathematical model. A large amount of operation data shows that the system is reliable, the efficiency of heat-furnace has been increased greatly, and a lot of energy has been saved. Such control system can also provide a lot of reliable real-time data for further on-line technology equipments. Moreover, a useful discovery for energy-saving emission reduction was made to develop advanced heat-furnace process control system.
