Description
Technical field
The utility model relates to a kind of control device, especially the Controlling System during a kind of metal heat treatmet.
Background technology
Orientation silicon steel production technology requires high than other silicon steel, precision more during to its control parametric variable in the course of processing, and as to the required temperature of its heating, the control of the data such as the time that keeps when also having thermal treatment, temperature requires very high.Required temperature had two kinds of modes when oriented silicon steel was annealed in annealing furnace, and a kind of is electrically heated, and this scheme energy consumption is high; Also has a kind of more energy-conservation mode, also be that the mode that everybody likes adopts gas-fired to produce heat, because producer gas generator all oneself is had in general steel enterprise, but adopting the mode of gas-fired when annealing, all is to realize that by the temperature that the size of manual regulation coal gas or air door is controlled in the annealing furnace temperature keeps and control, and the adjusting of this mode is thicker, wayward, low when high during temperature in the annealing furnace, can not guarantee that gas-fired is abundant simultaneously, cause waste.
PLC(Programmable logic Controller), refer to take the infant industry device of computer technology as the basis.In the PLC draft standard of International Electrotechnical Commission (International Electrical Committee) in 1987 promulgation, PLC is given a definition:
" PLC is a kind of specially for use the electronic installation of the digital operation operation that designs under industrial environment.It adopts the storer that can program, being used within it, section stores the instruction that actuating logic computing, sequential operation, timing, counting and arithmetical operation etc. operate, and can by digital or analog input and output, control various types of machineries or production process.
The utility model content
The purpose of this utility model is to provide a kind of coal gas and air combustion abundant for the deficiency that solves above-mentioned technology, and the annealing furnace temperature is controlled accurate a kind of oriented silicon steel annealing furnace control system.
In order to achieve the above object, a kind of oriented silicon steel annealing furnace control system that the utility model is designed, it comprises air and gas line, manual modulation valve, automatic regulating valve, wire, pressure detector, Temperature Detector, PLC controller, radiator tube; Be equipped with manual modulation valve and automatic regulating valve on described air and the gas line, described automatic regulating valve switch joins by wire and PLC controller, described pressure detector is connected wire and is connected with PLC with Temperature Detector, described Temperature Detector is arranged in the annealing furnace and close radiator tube; Described coal gas and air line are terminal to be igniting place, and igniting place is arranged in the radiator tube, and igniting place is provided with ignition controller, and ignition controller is connected by wire with PLC.
Described Temperature Detector is K type thermopair.
For guaranteeing each for the controllability of hot-zone temperature, every district establishes a temperature regulating and controlling loop, and every district gas line and air line are equipped with automatic regulating valve, regulate the flow of coal gas and air by the aperture of variable valve, reach the purpose of regulating heating power.The Temperature Detector signal advances PLC through wire, according to the fixed temperature of giving of computer, determine to cut off coal gas or air for the joint amount, or igniting improves the temperature in the body of heater.
Description of drawings
Fig. 1 is structural representation of the present utility model.
