Abstract
The invention relates to a heat treatment furnace temperature fuzzy control system. The system is characterized by comprising a controller, gas control valves and thermocouples, wherein the gas control valves and the thermocouples are connected with the controller; the gas control valves are arranged in the pipelines of gas nozzles, the gas nozzles are arranged in heating sections of a heat treatment furnace respectively, the thermocouples are arranged in the heating sections of the heat treatment furnace respectively; and the controller controls and adjusts the gas control valves according to the data fed back by the thermocouples so as to adjust the gas injection amount. In the heat treatment furnace temperature fuzzy control system, the thermocouples are used to measure the furnace temperature of each heating section in the heat treatment furnace, and the corresponding gas control valve is adjusted to control the gas injection amount after the treatmnet of a fuzzy control module of the controller. Therefore, the furnace temperature of the heat treatment furnace is accurately controlled and timely adjusted and the heat treatment quality of the steel wire for the steel wire rope is increased.
Description
Technical field
The present invention relates to a kind of system, especially relate to a kind of thermal treatment furnace temperature Fuzzy control system, be used for the Control for Kiln Temperature of the heat treatment furnace of rope wire.
Background technology
In the thermal treatment of rope wire, temperature control has determined the quality of steel wire sorbitizing, generally in thermal treatment; Temperature is set in a fixed scope; Through the temperature of thermocouple sensor mensuration heat treatment furnace, manual work is pressurizeed or is reduced pressure and controls the Heating temperature of heat treatment furnace then, and this regulating error is bigger; Time lag, heat treated quality also there is certain influence.
Summary of the invention
The applicant has carried out the research improvement to above-mentioned problem, and a kind of thermal treatment furnace temperature Fuzzy control system is provided, and accurately controls and in time adjust the furnace temperature of heat treatment furnace, improves the thermal treatment quality of rope wire.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of thermal treatment furnace temperature Fuzzy control system comprises unit, gas control valve and electroheat pair, and said gas control valve and electroheat pair connect said unit respectively; Said unit is a fuzzy controller, is provided with fuzzy control model; Said gas control valve is arranged in the pipeline of combustion gas nozzle, and the combustion gas nozzle is installed in respectively in each heating zone of heat treatment furnace, and said electroheat pair is separately positioned in each heating zone of heat treatment furnace; Said unit is according to the control of electroheat pair feedback data and regulate gas control valve, adjustment combustion gas straying quatity.
Technique effect of the present invention is:
A kind of thermal treatment furnace temperature Fuzzy control system disclosed by the invention; Measure the furnace temperature of each heating zone in the heat treatment furnace by electroheat pair; And handle the back through the fuzzy control model of unit and regulate corresponding gas control valve control combustion gas straying quatity; Thereby accurately the furnace temperature of heat treatment furnace is also in time adjusted in control, improves the thermal treatment quality of rope wire.
Description of drawings
Fig. 1 is a module map of the present invention.
Fig. 2 is a structural representation of the present invention.
Embodiment
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in 2, the present invention includes unit 2, gas control valve 3 and electroheat pair 1, gas control valve 3 and electroheat pair 1 connect unit 2 respectively.Be provided with 4 heating zones in the heat treatment furnace 5, the both sides up and down of each heating zone are provided with electroheat pair 1, are respectively applied for the furnace temperature of measuring in each heating zone; Be provided with combustion gas nozzle 4 in each heating zone; Combustion gas nozzle 4 through 4 igniting of combustion gas nozzle, circulates in heat treatment furnace 5 internal heating through the pipe connection fuel gas source; Gas control valve 3 is separately positioned in the pipeline of corresponding combustion gas nozzle 4, is used to control the combustion gas straying quatity of corresponding combustion gas nozzle 4.Unit 2 is according to the control of electroheat pair 1 feedback data and regulate gas control valve 3, the combustion gas straying quatity of adjustment combustion gas nozzle 4.In the present embodiment, unit 2 is a fuzzy controller, is provided with fuzzy control model.
In the heat treatment process of wireline steel wire, whole heat treatment furnace inside circulates air with reflux type fully, and the temperature difference is smaller in the body of heater, and 1 detected temperatures of each thermopair and actual temperature are basic identical.The temperature value input unit 2 that thermopair 1 detects; 2 pairs of temperature values of unit carry out obfuscation according to knowledge base, according to the data of knowledge base the data of obfuscation are carried out reasoning again, according to the requirement of knowledge base the result of reasoning are carried out sharpening; Output to the combustion gas straying quatity of controlling each heating zone on the gas control valve 3 then; Thereby the Heating temperature in the control heat treatment furnace when temperature changes in the heat treatment furnace, can obtain in time accurate adjustment.
