Distributed parameter dynamic control model of 31m vertical quench furnace

Due to the complex structure of the large vertical quench furnace, it is difficult to establish its distributed parameter control model. In this paper, under the premise of high-precision temperature control accuracy, the furnace structure is simplified reasonably. By the simplification of component heating process in the multi-zone heating furnace, a second order partial differential equation of distributed parameter system is established. The actuators locations resulting in uncontrollable system are found by mode decomposition method. Influence on temperature homogeneity by actuators quantity is simulated and the rationality of dynamical model structure is certified.
