Abstract
In the production sequence of the aluminum product, heating treatment is an important sequence according to develop the quality of the products.Heating treatment of the aluminum technology is developed to become one of the important part of the heating treatment .also the aluminum annealing furnace is the equipment which used so widely about the aluminum treatment.It also can adjust the configuration of product in all kinds of large aluminum project. And also the key equipment to add the affixation of the product, improving the compete of the project .so design the control system of the annealing furnace in reason and the real time monitoring the production status need us to learn and study very deeply.
This system introduced the characteristic and practicability of a new type aluminum annealing furnace. Designing and carrying out the aluminum annealing furnace production monitoring system which developed based on the Wonderware company and Intouch configuration software .through application and practice prove, this equipment design very well, making choiceness, control precision, high equality of the furnace temperature .the system has very kind HMI. Operation convenience, high extending character, maintenance and changing convenience .High depending character. Achieve the function to real time monitoring annealing furnace production in all aspects.
