Abstract

The invention discloses an impulse burner heating output control method. The impulse burner heating output control method comprises the steps of alternately implementing a heating control method and acooling control method; and leaving part of burners unused while it is ensured that the heating and cooling output requirements are met in the heating process and the cooling process through the heating control method and the cooling control method. Thus, compared with the prior art, the impulse burner heating output control method has the advantages that during heating and cooling switching, there are always part of the burners not to undergo the cooling and heating alternate switching process; accordingly, the shock cooling and shock heating frequency of radiant tubes corresponding to the burners of which the cooling and heating alternate frequency is reduced is certainly reduced; and therefore, the phenomena of cracks of the radiant tubes can be reduced, the production cost can be lowered, the production time wasted by replacing the damaged radiant tubes is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cold continuous vertical annealing, in particular to a pulse type burner heating output control method and system. Background technique [0002] In the steel manufacturing process, the cold continuous vertical annealing process requires the control of the burner. At present, the burner control mode of most annealing furnaces is "pulse" control. Due to the influence of furnace condition fluctuations, all burners need to work alternately between cold and hot, which leads to frequent cracking of radiant tubes and increases production costs. Contents of the invention [0003] The embodiments of the present application provide a pulsed burner heating output control method and system, which can effectively reduce the alternation of heating and cooling of the burner, solve the problem of frequent cracking of the radiant tube and increase the production cost. [0004] On the one hand, the present application p...
