Description
Technical field:
The utility model is relevant with industrial resistor furnace for heat treatment heater.
Background technology:
Various industrial resistor furnace for heat treatment in order to guarantee thermal treatment quality, all will be determined heat treatment process parameter according to the performance that part after the material of pending part and the heat treatment should possess.In many heat treatment parameters, most important parameter is " temperature ".
Normally magnitude of voltage and the length of conduction time that is added in threephase load resistance two ends by change is controlled temperature in the stove.Although it is identical equal substantially with the load resistance resistance to be added in the voltage at threephase load resistance two ends, owing to reasons such as furnace constructions, the temperature of different spatial differs greatly in the stove, i.e. " temperature field " in the stove and inhomogeneous.And whether " temperature field " in the stove be even, is the key that directly influences the work thermal treatment quality.
Resistor furnace for heat treatment, more even in order to make temperature field in furnace, traditional way is: arrange heater element meticulously.Ex post, the uniformity of temperature has certain effect in the stove to improving.But, because the Temperature Distribution of each spatial point in the stove is the problem of " field ".The structure of stove, environment temperature, the method for arranging of heater element, the thickness of furnace layer and material behavior, and the not equal many factors of the heat radiation situation of body of heater each several part, all can influence the uniformity in this " temperature field ", cause that temperature controlling becomes very complicated in the stove.Even if adopt above-mentioned measure, the temperature value in the stove on each spatial point still differs greatly, and is difficult to satisfy the heat treatment of workpieces technological requirement, thereby has influence on the quality of product.
Resistor furnace for heat treatment is usually by three-phase alternating-current supply power supply (seeing accompanying drawing 1 for details).According to technological requirement, control the magnitude of voltage that is added in the heater element two ends and the length of conduction time by " master switch " and " temperature regulation controller (WTKQ) ", thereby reach the purpose of regulating temperature in the control stove.Traditional adjustment control mode is: the control signal that temperature regulation controller sends is given threephase load resistance simultaneously, the magnitude of voltage at each resistance two ends with conduction time length be the same.As mentioned above, this control mode can not guarantee that temperature field in furnace is even.
The content of utility model:
The purpose of this utility model provides and a kind ofly makes the adjusting of temperature field in furnace easy, improves the online adjusting heater in temperature field that temperature field in furnace distributes.
The utility model is achieved in that
The online adjusting heater in the utility model temperature field, load resistance or inductance (1) are connected with master controller (2), master controller (2) is connected with temperature regulation controller (3) with three phase mains (A, B, C), the input IC of temperature regulation controller (3) is connected with sensor, output IO is connected with the control end of master controller (2) by adjustable resistance (4), load resistance (1) or inductance are connected for triangle with three phase mains (A, B, C), tie point is positioned at master controller (2) input, and master controller (2) is IGCT or semiconductor module.
The utlity model has following advantage:
The characteristics of " the online adjusting device of temperature field in furnace " are: the first, and make the adjusting work of temperature field in furnace become very easy.Past is regulated furnace temperature by " arranging heater element meticulously " method, after tested, if find that the temperature field is still inhomogeneous, could adjust after the cooling of stoves such as needs after adjusting again, and is time-consuming bothersome; And now can be at any time at " temperature regulation controller (WTKQ) " enterprising line operate, the limit is adjusted, and the limit test was both convenient, and was quick again; Second has improved the distribution of temperature field in furnace, has reduced temperature difference on interior each spatial point of stove, the past, general resistor furnace for heat treatment, maximum temperature difference is ± 15 ℃～± 8 ℃ between the interior each point of stove, adopts " the online adjusting device of temperature field in furnace " afterwards, to be reduced to ± 3 ℃～± 2 ℃.So, temperature just is strictly controlled within the scope of Technology for Heating Processing requirement in the stove, thereby has guaranteed the thermal treatment quality of part, has finally reached the purpose of enhancing product performance.
Utilization " the online adjusting device of temperature field in furnace " can be regulated ohmic load, inductive load.
Description of drawings:
Fig. 1 is the temperature field in furnace adjusting device that traditional star is connected with triangle.
Fig. 2 is a structure chart of the present utility model.
The specific embodiment:
" the online adjusting device of temperature field in furnace " is after finishing the resistor furnace for heat treatment installment work, threephase load is switched on simultaneously, by " temperature regulation controller (WTKQ) " the added voltage in every phase load resistance two ends is set at different value, tests temperature field in furnace then.Like this,, respectively try the temperature at control point repeatedly in the test furnace, just can find out the optimum voltage value of stove wind temperature field each phase load resistance when the most equal, the control parameter of coming design temperature control instrument then according to this optimum value through repeatedly changing setting value.
Referring to figure two, 1R, 2R, 3R are adjustable resistance 4; R is ohmic load 1 (heating element heater), and 1K-3K is single-phase module or bidirectional triode thyristor element 2 (solid-state relay).
The input point IC termination of temperature regulation controller 3 is received the input signal of sensor, after temperature regulation controller 3 computings relatively, through the IO output port, be divided into single channel or multi-way control signals, set by adjustable resistance 4:1R-3R, regulate of triggering angle or " the dutycycle control " of the size of 1K-3K control end control voltage, reach the difference of the voltage swing that each phase load resistance R is applied master controller 2, realize the adjusting of power output, thereby find out the optimum value of temperature field in furnace.In fact, stove is through after long-term the use, and variation has taken place the state of equipment thereupon, can adopt equally this moment " the online adjusting device of temperature field in furnace ", to guarantee the uniformity of temperature field in furnace.
