Problems solved by technology

[0002] In the alumina roasting furnace used in the metallurgical process, the temperature control of the alumina roasting furnace is currently adjusted manually by the operator. Factors such as gas regulating valve and other factors directly affect the temperature of the alumina roasting furnace, and the temperature of the alumina roasting furnace determines the product quality and energy consumption indicators. Therefore, the existing technology requires manual adjustment and monitoring by the operator frequently, and the operator's work intensity is high. At the same time, it has high requirements on its operation accuracy and real-time performance, which no longer meets the needs of metallurgy.

Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] Such as figure 1 As shown, the fuzzy automatic control method of alumina roasting furnace temperature in the present embodiment is as follows:

[0039] Step 1: Based on the raw material weighing sensor in the roaster, collect the actual value f of the raw material cutting amount at the time point k of the sampling period;

[0040] Step 2: When the actual value f of raw material cutting amount is greater than the rated amount of raw material cutting f 额 70% and the actual value f of raw material cutting amount is less than or equal to the rated amount of raw material cutting f 额 When 90% of , select fuzzy automatic control based on the gas regulating valve V as th...

Abstract

The invention discloses a fuzzy automatic control method for the temperature of an alumina roasting furnace. Firstly, the actual value f of raw material cutting amount is collected, and its value is compared with the rated amount of raw material cutting, so that the control target based on the gas regulating valve V is selected. Fuzzy automatic control, or choose fuzzy automatic control based on the raw material feeding amount F as the control target. In the present invention, the two factors affecting the temperature of the alumina roasting furnace, the raw material feeding amount and the gas regulating valve, are taken as prominent main factors, and the fuzzy thinking method of a person is simulated by applying the knowledge of fuzzy set theory, fuzzy language variables and fuzzy logic reasoning. The computer realizes the same control as the operator, based on fuzzy sets, fuzzy language variables and fuzzy logic, directly expresses human judgment and thinking process in a relatively simple mathematical form, thereby reducing the operator's work intensity and embodying automatic control at the same time accuracy and real-time.
