The application discloses a kind of multi-
modal adaptive
furnace temperature control method,
system and
continuous annealing furnace based on space-time thermal field decoupling, multiple independent heating zones are provided in the
continuous annealing furnace, multiple groups of staggered arrangement burners are arranged in each heating zone, four-stage
adaptive control strategy based on temperature ratio segmentation and thermal field space-
time distribution collaborative control, including: fast response heating zone, proportional regulation transition zone, pulse cross uniform zone, dynamic thermal field maintenance zone. By decoupling
furnace temperature control and thermal field
spatial distribution, using the way of spatial grouping pulse activation + time staggered control, the
rapid response, accurate regulation and uniform maintenance of
furnace temperature are realized.The application effectively solves the technical problems of temperature overshoot, response
lag, thermal field unevenness,
high energy consumption and other technical problems in the traditional
control mode, significantly improves the quality of
strip steel heat treatment and energy utilization efficiency.
