Research On Computer Process Control Of Reheat Furnace For Medium Heavy Plate

The most important equipment on steel rolling line is Reheat furnace which has a large energy consumer. For reheat furnaces of steel enterprises ,the technology of slabs heating directly affects strip steel product quality, energy consumed and mill life. So it is important to extend optimal setting control technology. The purpose of reheat furnace production is to achieve the fewest stock scale loss and energy consumption, and the important is to acquire the slab temperature distribution rolling required. Aiming at above problems, this paper includes the work as follows:1. Based on thermodynamics, the slab temperature prediction model is established, which solves the problem that slab temperature is immeasurable and makes important foundation for optimal setting control of reheat furnace.2. Reheat furnace process control is designed according to the actual situation of the medium and heavy plate, a software system of reheat furnace control is developed by using the object-oriented use case analysis and design method and compiles cooling control software system design documents, realizes this system using VC++.3. According to the actual situation of plate production, the system temperature field model is reliable, strong resistance to interference.
