Abstract
The utility model provides a kiln with a constant temperature control system, relates to kiln fittings, and particularly relates to the kiln with the constant temperature control system capable of automatically controlling the temperature by infrared induction and temperature measurement. The kiln with the constant temperature control system, provided by the utility model, comprises a kiln body and a heating device connected with pipelined gas, and is characterized by further comprising an infrared thermodetector and a control device, wherein the infrared thermodetector is mounted at a furnace mouth of the kiln, and the control device is connected with the infrared thermodetector and the heating device respectively. The kiln with the constant temperature control system is simple in structure, convenient to use, and reasonable in design; and the infrared thermodetector is precise in temperature measuring and very sensitive in temperature variation reaction, the measured temperature is timely fed back to the control device, and the volume of the pipelined gas is controlled by the control device, so that the temperature is constantly and precisely controlled.
Description
Technical field
The utility model relates to the stove accessory, especially a kind of infrared induction thermometric that utilizes, the stove with thermostatic control system of energy A.T.C.
Background technology
Iron scale is one of primary raw material of producing the bonded permanent ferrite magnetic, and China almost just brings into use iron scale in the starting stage of setting up permanent-magnet ferrite industry.Yet, because iron scale is subject to the factor affecting such as rolling shapes, collection situation, become split pole unstable, and impure more, if without anticipating, be difficult to guarantee the magnetic property of bonded permanent ferrite magnetic.In order to utilize this source of iron scale raw material wide, that price is low to produce the bonded permanent ferrite magnetic of medium-to-high grade performance, must carry out deep processing to it.The technological process of production of bonded permanent ferrite magnetic is mainly: will advance factory's iron scale classification, mix → fine and close → beat cake → sintering → coarse crushing → fine grinding → washing → dehydration → tempering → cooling → dispersion → classification → packing → check warehouse-in through washing magnetic separation → chemical examination → raw material stoving → coarse crushing → additive.Wherein, in drawing process, the lower piped gas of use cost is fuel usually, and the bonded permanent ferrite magnetic is heated temper.For keeping stable through the magnetic property of bonded permanent ferrite magnetic after the tempering, normally temperature is controlled between 800 to 1200 degrees centigrade.The most frequently used temperature measuring equipment is thermocouple at present, thermocouple converts temperature measured in the tempering stove to the thermo-electromotive force signal, converts the temperature of measured medium to by electric meter, again by the size of Artificial Control gas supply amount, control temperature in the tempering furnace with this.Use thermocouple to be temperature measurement tool, can reduce cost of investment, but because thermocouple damages easily, strengthened maintenance cost in the later stage production; Simultaneously, be difficult for finding after thermocouple damages, cause the defect ware rate to improve.Through studies show that, the bonded permanent ferrite magnetic that iron scale is produced is in drawing process, and optimum temperature is between 900 to 950 degrees centigrade, and thermocouple is slower to the variations in temperature reaction because of its material character, is unfavorable for the accurate control of temperature.
Summary of the invention
To be solved in the utility model is exactly that existing bonded permanent ferrite magnetic is in drawing process, use the thermocouple measuring temperature reaction slower, be unfavorable for accurate control, the problem that thermocouple is fragile simultaneously, the rear difficulty of damage is found, provide a kind of employing infrared induction thermometric, the stove with thermostatic control system of energy A.T.C.
Stove with thermostatic control system of the present utility model, the heater that comprises body of heater and connecting pipe coal gas, it is characterized in that this stove also comprises infrared radiation thermometer and control device, infrared radiation thermometer is installed in the fire door place of stove, and control device is connected with infrared radiation thermometer and heater respectively.
Infrared radiation thermometer is by measuring the infrared energy that distributes in the stove, measure accurately its surperficial temperature, with this temperature feedback to control device, gas supply amount by control device control heater, temperature in the control tempering stove is floated in 900 to 950 degrees centigrade, guarantees that with this bonded permanent ferrite magnetic after tempering can obtain better, more stable magnetic property.
This temp testing controlling system makes the bonded permanent ferrite magnetic accurately obtain temper under the stationary temperature by the accurate control to the stove temperature.
Compare with thermocouple temperature measuring apparatus, the beneficial effects of the utility model are:
(1) stove with thermostatic control system of the present utility model is simple in structure, easy to use, reasonable in design;
(2) infrared radiation thermometer measurement temperature is accurate, and is very sensitive to the variations in temperature reaction, and the temperature that records is in time fed back to control device, controlled the size of piped gas by control device again, thereby reaches temperature constant, accurate control.
