Abstract
The utility model relates to a carbon potential control system of a heat treatment apparatus, which comprises a carbon potential control meter, the input end of the carbon potential meter is connected with a thermocouple and an oxygen probe which are arranged in a furnace body, and the output end of the carbon potential meter is connected with a carbon burning control solenoid valve and a carburization control solenoid valve; and the carbon burning control solenoid valve and the carburization control solenoid valve are respectively connected on the furnace body through pipelines. The carbon potential control system has the main advantages of (1) high control precision; (2) high responding speed; (3) high sensitivity; (4) convenience for maintenance: when a part of the apparatus is broken down, only a control system of a passageway needs to be closed temporarily, or the control method of the passageway is changed into manual control without stopping a whole system; and (5) improvement of measurement accuracy of the oxygen probe due to an additionally automatic carbon burning system, therefore, the accuracy in measurement and control of the whole system is improved.
Description
Technical field:
The utility model relates to a kind of carbon potential control system of Equipment for Heating Processing.
Background technology:
At heat treatment industry, when general workpiece is implemented to quench, need in furnace gas, to heat, when if the carbon potential of furnace gas surpasses the carbon content that workpiece originally is, then workpiece becomes layer carburizing reflection can take place, though can improve wear resistance, but toughness also decreases, otherwise when the carbon potential ratio of furnace gas adds the heated steel carbon content when low, then decarburization can take place in workpiece, even the surface forms one deck oxide skin, make hardness value reduce, wear resistance is not good, does not reach heat treated effect.As seen also the mechanical property after the heat treatment of workpieces is closely bound up in the carbon-potential control of furnace gas.
Summary of the invention:
The utility model provides a kind of new carbon potential control system, thereby improves control accuracy, guarantees mechanical property.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of carbon potential control system of Equipment for Heating Processing, be provided with the carbon-potential control instrument, the input terminus of described carbon-potential control instrument be used to be arranged on the intravital thermopair of stove, oxygen probe is connected, its output terminal then is connected with burning carbon control magnetic valve, carburizing control magnetic valve, and described burning carbon control magnetic valve, carburizing control magnetic valve are connected to body of heater by pipeline.
Main advantage of the present utility model is as follows:
(1), control accuracy height.
(2), speed of response is fast.Magnetic valve need not carry out angle and convert, and directly received signal is controlled.
(3), highly sensitive.State and the unlatching cycle that requires to adjust magnetic valve that can be different according to equipment.The adjustment cycle of magnetic valve can second timing.
(4), easy to maintenance.Certain district of equipment only needs the Controlling System of this passage of temporary close or the control of this passage is changed into manually when breaking down, and need not close total system.
(5), increase the automatic carbon black system of burning, the measuring accuracy of raising oxygen probe, thereby the accuracy that the raising total system is measured and controlled.Oxygen probe is as the sensing member of measuring furnace atmosphere, and each program of The whole control system all is to adjust from the signal of oxygen probe by receiving.So the measuring accuracy of oxygen probe is the key of total system.When the carbon black of oxygen probe surface parcel because of can not in time clearing up the precision that has a strong impact on its measurement, when the carbon potential in the stove produces fluctuation, system can not obtain in time and information accurately, thus influenced total system can not be accurately with adjust furnace atmosphere timely.For this reason, added automatic burning carbon black system in this system, ventilation (air) was removed once automatically every 3 hours.Guaranteed the measuring accuracy of oxygen probe by this improvement, made whole carbon control system carry out promptly and accurately adjustment to furnace atmosphere, improved the measurement and the control accuracy of system greatly, thereby guaranteed the stability of furnace atmosphere according to accurate information.
Description of drawings:
Accompanying drawing 1 is an overall schematic of the present utility model.
Among the figure: 1, carbon-potential control instrument; 2, body of heater; 3, thermopair; 4, oxygen probe; 5, burn carbon control magnetic valve; 6, carburizing control magnetic valve.
Embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
The carbon potential control system of a kind of Equipment for Heating Processing as shown in Figure 1, be provided with carbon-potential control instrument 1, two input terminuss of described carbon-potential control instrument 1 are connected with the thermopair 3, the oxygen probe 4 that are used to be arranged in the body of heater 2 respectively, two output terminal then is connected with burning carbon control magnetic valve 5, carburizing control magnetic valve 6 respectively, prevented the interference between each passage, thereby improved the control accuracy of system, described burning carbon control magnetic valve 5, carburizing control magnetic valve 6 are connected to body of heater 2 by pipeline.
During work, in the body of heater 2 atmosphere with oxygen probe 4 as sensing member, the temperature of measuring burner hearths by the oxygen gesture and the thermopair 3 of atmosphere in the mensuration body of heater 2 inputs to carbon-potential control instrument 1, carbon-potential control instrument 1 calculates the signal of actual carbon potential and the set(ting)value of carbon-potential control instrument 1 compares, carry out the mathematical model computing, be directly delivered to the input that the high carburizing control magnetic valve 6 of sensitivity is adjusted enriched gas by after converting carbon-potential control instrument 1 being regulated control signal, thereby reach required carbon potential value, and make it stable.Again because oxygen probe 4 in use easily makes its surface superscribe carbon black, and oxygen probe 4 is as the sensing member of measuring atmosphere in the body of heater 2, each program of The whole control system all is to adjust from the signal of oxygen probe 4 by receiving, so the measuring accuracy of oxygen probe 4 is keys of total system.When the carbon blacks of oxygen probe 4 surface parcel because of can not in time clearing up the precision that has a strong impact on its measurement, when the carbon potential in the body of heater 2 produces fluctuation, system can not obtain in time and information accurately, can not accurately and timely adjust body of heater 2 interior atmosphere thereby influenced total system.At this moment, then need start to burn in 5 pairs of bodies of heater 1 of carbon control magnetic valve and carry out ventilation treatment, native system generally is set at every 3 hours ventilation (air) automatically and removes once, when every through 3 hours, burn carbon control magnetic valve 5 and receive carbon-potential control instrument 1 signal, carry out and finish preplanned mission.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
