| Abstract: | In view of the existing problems in the original combustion control system of continuous annealing furnace, the heating section of radiant tube was optimized. Based on DCS distributed control system of YOKOGAWA, the proportion of air and COG and other influencing factors were analyzed, and the ralationship among these control parameters was established, so then the transfer function of annealing furnace combustion system was successfully enduced. By using the method of timing pulse combustion control to optimize the heating section of radiant tube, which was proved to have a remarkable effect on energy conservation and environmental protection, the control accuracy was optimized, and the surface oxidation of strip steel was reduced , and the heating efficiency was improved at the same time. |
