With reference to figure 1, temperature sensor 1 is arranged in vacuum air cooling heat treatment furnace, and in order to survey the temperature in vacuum air cooling heat treatment furnace, general temperature sensor 1 should be tried one's best near workpiece to be cooled in vacuum air cooling heat treatment furnace, with the temperature of Obtaining Accurate workpiece.Temperature controller 2 is connected with temperature sensor 1, the temperature information detecting to obtain sensor 1.Well heater 3 is mainly used in to the heat supply of vacuum air cooling heat treatment furnace, and it can be the well heater that vacuum air cooling heat treatment furnace itself has, or the extra well heater arranging.And blower fan 4 is mainly used in the cooling of vacuum air cooling heat treatment furnace.Temperature controller 2, according to the temperature information receiving, is controlled the operation of blower fan 4 and well heater 3 and stops, and namely, can, according to the actual temperature of vacuum air cooling heat treatment furnace, adjust the rate of temperature fall of vacuum air cooling heat treatment furnace.
Figure 2 shows that another embodiment schematic diagram of the utility model temperature controlling system, as shown in Figure 2, temperature controlling system comprises: temperature sensor 101, temperature sensor 102, heating temperature control instrument 201, cooling temperature controller 202, PLC8, power regulator 5, frequency transformer 7, adjusting transformer 6, well heater 3 and blower fan 4.
With reference to figure 2, temperature sensor 101 and temperature sensor 102 are arranged in vacuum air cooling heat treatment furnace, in order to survey the temperature in vacuum air cooling heat treatment furnace, generally, temperature sensor 101 and temperature sensor 102 should be tried one's best near workpiece to be cooled in vacuum air cooling heat treatment furnace, with the temperature of workpiece in Obtaining Accurate cooling room.Temperature sensor 101 and temperature sensor 102 are close to each other in order to avoid the two temperatures value of surveying exists error.Heating temperature control instrument 201 connects temperature sensor 101 and power regulator 5, heating temperature control instrument 201 obtains the temperature information that temperature sensor 101 detects, and according to temperature information to power regulator 5 sending controling instructions, the power providing to well heater 3 to change power regulator 5.Regulate transformer 6 to match, be connected between power regulator 5 and well heater 3, regulate transformer 6 in the time that the voltage rating of power regulator 5 output voltages and well heater 3 is inconsistent, the voltage that power regulator 5 is exported mates with the adjusting of the voltage rating of well heater.Cooling temperature controller 202 connects temperature sensor 102 and frequency transformer 7, cooling temperature controller 202 obtains the temperature information that temperature sensor 102 detects, according to the temperature information that receives temperature sensor 102, to frequency transformer 7 sending controling instructions, frequency transformer 7, according to the steering order of cooling temperature controller 202, is adjusted the rotating speed of blower fan 4.
With reference to figure 2, the utility model temperature controlling system comprises the Controlling System of two cover closed loops.Wherein a set of Controlling System comprises: temperature sensor 101, heating temperature control instrument 201, power regulator 5 and well heater 3.Another set of Controlling System comprises: temperature sensor 102, cooling temperature controller 202, frequency transformer 7 and blower fan 4.And control the operation of two sleeving temperature Controlling System by PLC8, and that is to say, by the control of PLC8 or the operation of switching heating temperature control instrument 201 and cooling temperature controller 202, and then the operation of controlling or switching well heater 3 and blower fan 4.
With reference to figure 2, for vacuum air cooling heat treatment furnace, its process of cooling can comprise two stages, is respectively hot stage and low thermophase.At hot stage, the speed of furnace temperature naturally cooling is greater than the required rate of temperature fall of technique, realize constant speed cooling, needs well heater 3 to carrying out certain thermal compensation in stove.At low thermophase, the rate of cooling that furnace temperature is lowered the temperature naturally declines, be less than the required rate of temperature fall of technique, temperature controlling system, to the rare gas element that is filled with certain pressure intensity in stove, starts blower fan 4 simultaneously, and stops well heater 3, adjust the rotating speed of blower fan 4 by frequency transformer 7, according to actual state, strengthen gradually blower fan 4 air quantity, realize constant speed cooling.Low thermophase can also comprise the isothermal process that technique is required, and isothermal process generally for example, is carried out in low-temperature zone (being 350 DEG C of left and right), now naturally cooling state if, and the accumulation of heat meeting of stove inner thermal insulating layer causes furnace temperature to rise.Therefore, for realizing isothermal process, need temperature controlling system that cooling vacuum oven speed is adjusted to suitable with the speed of accumulation of heat, thereby maintain temperature-stable in stove.
Also by reference to the accompanying drawings the utility model is described in further detail below by embodiment, Fig. 3 is the schematic diagram of the temperature curve of constant speed cooling, with reference to figure 2 and Fig. 3, curve A represents the downcurve of temperature under perfect condition, curve B represents the temperature downcurve under temperature controlling system control, and curve C is the temperature downcurve in furnace temperature naturally cooling situation.Comparison curves C and curve A are known, and for the situation of furnace temperature naturally cooling, the speed of being down to 700 degree from 1150 degree in temperature is very fast, and the speed that temperature continues decline from 450 degree is very slow, and temperature curve is close to level.Therefore, in order to reach actual temperature curve close to temperature curve A, be namely adjusted to temperature curve A and substantially overlap for realizing temperature curve C, need to control the rate of temperature fall of vacuum air cooling heat treatment furnace.
With reference to figure 2 and Fig. 3, temperature controlling system for example, at hot stage (being greater than 700 degree), the slope of temperature curve C is greater than temperature curve A, furnace temperature rate of temperature fall is very fast, now need furnace temperature to compensate, the closed loop system consisting of temperature sensor 101, heating temperature control instrument 201, power regulator 5 and well heater 3 is carried out function of temperature compensation control.Operator can be by temperature curve A by programming, add in heating temperature control instrument 201, the preset temp of the temperature signal that heating temperature control instrument 201 gathers by temperature sensor 101 and temperature curve A contrasts, according to the temperature approach of the two, calculate applicable thermal compensation power signal, by compensation power signal power input setter 5, so that the heating power on well heater 3 is adjusted.So, the temperature signal of the furnace temperature repeatedly gathering by temperature sensor 101 returns to heating temperature control instrument 201, again calculates and revise output, to realize closed-loop control.
For example, at low thermophase (being less than 700 degree), the slope of temperature curve C is less than temperature curve A, now, need to accelerate the rate of temperature fall of furnace temperature, therefore, PLC8, at the point of interface (certain temperature spot below 700 degree) of high temperature, low thermophase, sends instruction to heating temperature control instrument 201, and heating temperature control instrument 201 control heaters 3 stop heating.Meanwhile, PLC8, at certain temperature spot of low thermophase, sends instruction to cooling temperature controller 202, and blower fan 4 is brought into operation.Now, the closed loop system that temperature controlling system consists of temperature sensor 102, cooling temperature controller 202, frequency transformer 7 and blower fan 4 is lowered the temperature.Operator equally can be by the low temperature part programming of temperature curve A, add in cooling temperature controller 202, the temperature signal that cooling temperature controller 202 gathers by temperature sensor 102 and the preset temp of temperature curve A contrast, and according to the temperature approach of the two, calculate the frequency signal of applicable blower fan 4.Frequency signal flows to frequency transformer 7, so that the rotating speed of blower fan 4 is regulated, thus the air quantity of adjusting blower fan 4.So, the temperature signal of the furnace temperature repeatedly gathering by temperature sensor 102 returns to cooling temperature controller 202, again calculates and revise output, to realize closed-loop control.
Finally, actual temperature curve can for example represent by the temperature curve B in Fig. 3, and temperature curve B fluctuates near temperature curve A.
Fig. 4 is the schematic diagram of the temperature curve of isothermal process, as shown in Figure 4, and with reference to figure 2 and Fig. 4, at low thermophase, if furnace temperature at 350 degree, may need to carry out isothermal processes, when isothermal processes, temperature curve should be a sea line, and namely temperature is to be stabilized in a value, as sea line D.
With reference to figure 2 and Fig. 4, the external factor that low-temperature zone exerts an influence to the rate of cooling of vacuum air cooling heat treatment furnace is more, comprises the air quantity of blower fan 4, temperature of cooling water, duct resistance, the efficiency of heat exchanger, shove charge situation etc.Temperature of cooling water is to have certain rule, and the situation of every stove is substantially similar; The structure of body of heater is depended in duct resistance, is constant substantially; Heat exchanger effectiveness depends on blower fan, and this is also basicly stable; There is certain difference in the shove charge situation of every stove, but this is not a crucial factor.Therefore, the factor having the greatest impact for rate of cooling is the air quantity of blower fan 4, and the utility model will be by the self-setting function of cooling temperature controller 202, using the air quantity of blower fan 4 as adjusting object, and the effect of the raising regulation and control of maximum possible.
In the initial stage of isothermal process, the heat storage capacity of vacuum air cooling heat treatment furnace is larger, now needs blower fan 4 to add Wind Volume, and in the time that the heat storage capacity of vacuum air cooling heat treatment furnace reduces, blower fan 4 reduces air quantity.Adjustment by cooling temperature controller 202 to blower fan 4 air quantity power, balances each other the rate of release of itself and accumulation of heat, thereby realizes the stable of furnace temperature.Finally, actual temperature curve can for example be represented by the temperature curve E in Fig. 3.Temperature curve E fluctuates near sea line D.
To sum up, temperature controlling system of the present utility model, controls blower fan and well heater respectively because the control of high temperature and low thermophase all adopts temperature controller, and operator only needs to set and get final product complete operation by processing requirement.In actual treatment production process, the control of cooling can realize automatization completely, is completely constantly sampled, calculates, is adjusted by temperature controlling system.Do not need in operation artificially during the course uninterruptedly to adjust, realistic operational requirement, this makes this system possess the feasibility of enforcement.
And temperature controlling system of the present utility model realized constant speed cooling truly or etc. temperature control, make equipment for Heating Processing possess rate of temperature fall and the predeterminable function of isothermal process simultaneously.This processes significant for the annealing of part mu-metal part and the gas quenching of part large mould.Solved in workpiece treating processes, rate of cooling is uncontrolled, after causing workpiece to be processed, and weave construction, mechanical property, the undesirable problem of physicals.
