Abstract

The invention discloses an intelligent optimization method for temperature control of a ceramic kiln. The intelligent optimization method comprises the following specific steps that step (1), during each firing process, a kiln controller performs PID control on the kiln temperature according to the set kiln temperature control curve through a PID control module; step (2), after each completion offiring, the kiln controller transmits the actual temperature data in the kiln to a PC through wireless communication; step (3), the ceramic firing result is scored and evaluated by a firing technician, and the score is input into the PC and forms a sample with the actual temperature data; step (4), the PC optimizes the kiln temperature curve according to the samples through the genetic algorithm;and step (5), the optimized temperature control curve is transmitted by the PC through wireless communication to the kiln controller for control of the next ceramic firing process. The intelligent optimization method achieves the effect of improving the quality of ceramic firing by optimizing the kiln temperature control curve.

Description

technical field [0001] The invention belongs to the technical field of control, and relates to an optimization method for temperature control of a kiln, in particular, applying the temperature control optimization method to a gas-fired ceramic kiln to achieve the effect of improving the quality of ceramic firing. Background technique [0002] In the firing process of ceramics, the entire kiln has to go through a process of heating up, keeping warm, and cooling down. Ceramics undergo complex changes with temperature in the furnace, and the temperature in the furnace plays a key role in the firing quality of ceramics. Furnace temperature is a nonlinear quantity with large hysteresis, which increases the difficulty of furnace temperature control. [0003] my country has a glorious ceramic production history and culture, but the firing technology of traditional ceramic kilns is still relatively backward. The temperature control of most small and medium-sized ceramic kilns basica...
