Annealing furnace energy-saving aspects promote industrial development should be better

With the development of science and technology and the engineering technical personnel's efforts, increasingly to develop in the direction of high yield, energy conservation and annealing furnace, furnace type structure more reasonable, compact annealing process will be, the annealing quality enhances unceasingly, meet the different needs of users.
To formulate reasonable continuous annealing process curve of metal recrystallization annealing temperature and cold rolling, the deformation level of the chemical composition of substrate, the heating speed, the original microstructure factors, such as how to finish the recrystallization annealing in line, can be in the production practice in different ways to satisfy the demands of various steel recrystallization temperature. However, change the strip heating and cooling in the annealing furnace q is the most effective way. To facilitate the operation, reduce artificial interference factors should formulate annealing process table, annealing curve drawing, to get the most out of annealing curve to the production practice.
Fully computerized control system operation control of modern continuous annealing furnace hot galvanizing unit including furnace tension control, shape control and running deviation control, combustion control, temperature control, furnace pressure control, etc. Control system should achieve the following functions: to adjust execution according to field instrument detection system; The fan start and stop the program logic control, safety monitoring system and cooling system, gas burner ignition and other logic control; Operating parameters, medium consumption and production statistics display and record; PC display system and the operator of exchange; Setting procedure, the operator designated, the mathematical model for calculation of dynamic control and accident of logic control, production report; Contact and exchange of information with process computer. Join the site instrument for the exchange of digital and analog signals. Strip steel based on the actual situation and the target heating system, through the mathematical model for the setpoint of furnace parameters automatically. Realize the above control function can play a maximum efficiency of the furnace, reducing furnace unit consumption.
