Process, the raw material strip after chemical cleaning, 1 after uncoiling, cleaning, drying, preheating, flame, heat radiation, radiation heating and soaking and hydrogen reduction, cooling, galvanized (aluminum zinc plating) and subsequent cooling, chemical, processing, finally complete the crimp baling process become the standard products, so many complex processes and institutions must,Use highly automated control systems to make them work together to meet the requirements of the production process. So!In our research more than similar foreign advanced control concept and technology, on the basis of combination of meishan, hot dip galvanized, hot dip aluminum zinc units, the characteristics of the design, development, a full set of hard and soft, safe, reliable and efficient instrument automation control system.
Units of two continuous annealing furnace temperature and combustion control system design is especially important, it is not, only affect the coating quality, but also determines the important physical and chemical properties. So this article on the hot galvanizing production line are given the entire instrument automation control system flow chart, focuses on heat mirror, aluminum zinc, hot dipped zinc production line in the control system design scheme of continuous annealing furnace. Our main work includes the following three aspects: first, design the hardware of the continuous annealing furnace excavation system including its network communication system. Second, design and debug the multiple monomer equipment control system of the continuous annealing furnace, such as: nitrogen hydrogen hybrid system, gas analyzer, etc., and connects them as the subsystem of the whole; Third, design and debug the temperature and combustion control system of continuous annealing furnace in accordance with the product production process requirements and the structural characteristics of meishan hot-dip galvanized and hot-dip aluminium-zinc annealing furnace. Finally, the continuous annealing furnace test of meishan hot dip galvanizing is presented. Several recorded data during production are used to demonstrate the effectiveness of its control system design and the subsequent work is carried out.Looking forward to.
