Referring to fig. 5, fig. 5 is a flowchart of a secondary charging control method.
The invention also provides a secondary feeding control method based on the vacuum metal atomization pulverizing furnace in the embodiment, which comprises the following steps:
s1, obtaining melting points of various elements in the alloy to be prepared;
s2, selecting at least one element as an element to be supplemented according to the melting points of various elements, wherein the element to be supplemented is lower than the melting points of other elements which are not selected, and the number of the elements to be supplemented is smaller than or equal to the number of the storage parts;
s3, obtaining the volatilization amount of each element to be supplemented;
s4, controlling the first driving device to drive all the storage parts which are completely filled to rotate and switch in a clockwise direction or a counterclockwise direction according to the volatilization amount so as to output raw materials of various elements to be supplemented; each storage part is respectively filled with raw materials of various elements to be supplemented according to the sequence of melting points of the elements to be supplemented in a clockwise direction or a counterclockwise direction;
S5, controlling the second driving device to drive the hopper to swing so as to throw the raw materials of the elements to be supplemented in the hopper into the crucible.
In this embodiment, in practical application, the temperature in the furnace will reach at least the highest melting point, so that all the raw materials can be melted into liquid metal, and for this purpose, the melting point of a part of the elements is lower than the highest melting point, so that the part of the elements will volatilize, and the part of the elements needs to be supplemented, and the part of the elements is the elements to be supplemented.
The number of the storage parts is limited, so that the secondary feeding device has a corresponding application range, and the specific application range is that the number of the types of elements to be supplemented is smaller than or equal to the number of the storage parts; if the number of the elements to be supplemented is larger than the number of the storage parts, part of the raw materials to be supplemented are stored in the storage parts without spare, so that the part of the elements to be supplemented cannot be supplemented, and the component content of the finished alloy powder is affected.
In addition, in practical application, in order to ensure the element components of the alloy to be uniform, the raw materials volatilized earlier should be supplemented preferentially (i.e. the raw materials are supplemented according to the melting point and the priority), otherwise, the supplementing time is too late, and even though the component content meets the requirement, the distribution of the element components is uneven, so that the quality of the finished alloy powder is affected.
By combining the structural design of the secondary feeding device in this embodiment, if various raw materials needing to be supplemented are arbitrarily filled into each storage part, on one hand, the control system needs to be provided with an additional identification module for identifying and determining the element type of the raw material corresponding to the filling of each storage part (so that the rotation can be controlled to switch each storage part to ensure the correct supplement of the raw material), obviously, the control system is more complex and the cost is higher; on the other hand, when each storage part is rotated and switched, a larger angle is likely to be required to be rotated and the rotation direction is required to be changed for a plurality of times to be switched to the corresponding storage part, so that more time is wasted in the rotation and switching process, and the overall operation efficiency is reduced;
for example, there are 6 storage parts, there are 6 second discharge ports correspondingly, and the 6 second discharge ports are uniformly distributed in circumference, and then the included angles between two adjacent second discharge ports are 360 °/6=60°; the element components of the alloy to be prepared comprise A, B, C and D, which are sequenced into ABCD from low melting point to high, at the moment, raw materials of element C, raw materials of element B and raw materials of element A are sequentially put into the adjacent 3 storage parts in a clockwise direction, when the raw materials need to be supplemented, all the storage parts only need to rotate in the clockwise direction, and because the element A is sequenced first, the first discharge port is aligned with the second discharge port of the storage part corresponding to the element A, so that raw materials of element A are put into the crucible; then, rotating the crucible by 60 degrees in the clockwise direction, and aligning the first discharge hole with the second discharge hole of the storage part corresponding to the element B, so that the raw material of the element B is put into the crucible; similarly, the crucible is rotated by 60 degrees in the clockwise direction, and the first discharge hole is aligned with the second discharge hole of the storage part corresponding to the element C, so that the raw material of the element C is put into the crucible; the rotation switching always keeps the rotation of the same direction at a smaller angle in turn (namely 60 degrees; if raw materials are arbitrarily filled in each storage part, for example, ACB is filled in sequence, when A is switched to B, the rotation is required to be 120 degrees, when B is switched to C, the reverse rotation of all the storage parts is required to be controlled to be 60 degrees, so that the input of the corresponding raw materials can be completed, the time waste in the rotation switching process is reduced, the overall working efficiency is effectively improved, meanwhile, the control system is free from arranging an identification module when the raw materials are filled in sequence, and the control system is greatly simplified.
The movement in the clockwise direction or the counterclockwise direction is generally performed with the stock portion storing the element to be supplemented having the lowest melting point as the starting point.
It should be noted that, the lower the melting point of the element to be supplemented, the earlier the volatilization, that is, the larger the volatilization amount, the more the raw material amount to be supplemented, and when the discharge amount of the element to be supplemented is measured later, the longer the measurement time of the element to be supplemented with low melting point, in order to ensure the element components of the alloy to be uniform and avoid too late supplementation, the raw material amount of the element to be supplemented with low melting point should be measured preferentially, that is, the raw materials of various elements to be supplemented should be supplemented sequentially in order from low melting point to high melting point.
In certain embodiments, the specific steps in step S3 include:
s31, acquiring a total smelting duration (the total smelting duration refers to the total duration of the heating operation);
s32, obtaining heating time required when the temperature in the furnace reaches the melting point of each element to be supplemented;
s33, acquiring a temperature change curve graph in the furnace;
s34, calculating the volatilization amount of each element to be supplemented according to the total smelting duration, the heating duration and the temperature change curve graph in the furnace.
In this embodiment, in practical application, the temperature in the furnace is generally heated to the highest melting point, for example, the elemental components of the alloy to be prepared include A, B, C and D, which are sorted into ABCD in order of melting point from low to high, the temperature in the furnace reaches the highest melting point D (i.e., the melting point of element D), and when the temperature in the furnace reaches the melting point a, the heating duration is 1 hour; when the temperature in the furnace reaches the melting point B, heating time is 2 hours; when the temperature in the furnace reaches the melting point C, heating time is 3 hours; when the temperature in the furnace reaches the melting point D, the heating time is 4 hours;
In the heating process, when the total smelting time is longer than 1 hour, volatilizing the raw materials of the element A; similarly, when the total smelting time is longer than 2 hours, volatilizing the raw materials of the element A and the raw materials of the element B; when the total smelting time is longer than 3 hours, volatilizing the raw materials of the element A, the element B and the element C.
Obviously A, B and C are taken as elements to be supplemented, and when the total smelting duration is longer than the heating duration, the elements to be supplemented volatilized, so that the volatilization amount of each element to be supplemented is related to the total smelting duration, the heating duration and the temperature in the furnace, and the volatilization amount of each element to be supplemented can be calculated according to the curve graphs of the total smelting duration, the heating duration and the temperature in the furnace.
The temperature change graph in the furnace is generated by the system by acquiring the temperature in the furnace body.
Specifically, in certain embodiments, the specific steps in step S34 include:
s341, acquiring the average heating temperature after the temperature in the furnace reaches the melting point of each element to be supplemented according to the temperature change curve graph in the furnace;
s342, obtaining the volatilization rate of each element to be supplemented according to the average heating temperature;
s343, calculating the volatilization amount according to the following formula:
；
wherein ,the volatilization amount of the i-th element to be supplemented is +.>For the total duration of smelting>For the heating period required for the temperature in the furnace to reach the melting point of the i-th element to be supplemented,/->Is in the liquid state for the i-th element to be supplemented>Volatilization rate at temperature (in g/min),>the average heating temperature after the temperature in the furnace reaches the melting point of the i-th element to be supplemented.
In this embodiment, the volatilization amount is related to the volatilization rate and time, and the volatilization rate is related to the temperature, and the volatilization rate can be obtained by experiment or table lookup according to the average heating temperature; the difference value between the total smelting duration and the heating duration shows the exceeding heating duration after reaching the melting point of the ith element to be supplemented, the temperature in the furnace gradually rises in the exceeding heating duration, and the raw material of the ith element to be supplemented continuously volatilizes in the exceeding heating duration; the average heating temperature after reaching the melting point of the i-th element to be supplemented= (highest melting point+melting point of the i-th element to be supplemented)/2.
In certain embodiments, the specific steps in step S4 include:
S4A1, acquiring a discharge rate of a first discharge port;
S4A2, calculating the discharging time of each storage part according to the volatilization amount and the discharging rate of each element to be supplemented;
S4A3, controlling the storage parts to output corresponding raw materials of elements to be supplemented according to corresponding discharging time, and controlling the first driving device to drive all the storage parts to rotate and switch to the next storage part in a clockwise direction or a counterclockwise direction when the corresponding discharging time is reached.
In this embodiment, since the opening size of the first discharge port is fixed, the discharge rate is also relatively constant, and after the discharge rate is obtained through an experiment, the discharge time=the volatilization amount/discharge rate of the i-th element to be supplemented; after the discharging time is obtained, the second discharging ports of the corresponding material storage part are controlled to be aligned with the first discharging ports (each second discharging port can be designed to be circumferentially and evenly distributed, in an initial state, the first discharging port is aligned with one of the second discharging ports, after that, each rotation fixed angle can enable the first discharging port to be aligned with the next second discharging port, for example, 6 material storage parts are shared, 6 second discharging ports are corresponding, 6 second discharging ports are circumferentially and evenly distributed, the included angle between every two adjacent second discharging ports is 360 degrees/6=60 degrees, in an initial state, the first discharging port is aligned with one of the second discharging ports, then each rotation of 60 degrees can control the first discharging port to be aligned with the next second discharging port, or the first discharging port and the second discharging port are monitored by the sensor to be aligned or not through each second discharging port, whether the object is in place or not is monitored by the sensor, the prior art is not monitored, the output is not repeated, and the output of the first replenishing element is stopped until the required replenishing quantity of the i is reached, and the required replenishing element is replenished, i is realized.
According to the embodiment, the weight sensor is not required to be arranged in the furnace body, the discharge amount is obtained through calculation, the acquisition cost of the sensor is reduced, and meanwhile, the phenomenon that the discharge amount cannot be obtained due to the fact that the weight sensor is damaged due to the influence of high temperature is avoided, so that the use of equipment is affected.
In certain embodiments, the specific steps in step S4 include:
S4B1, acquiring the discharge quantity of each storage part through a weight sensor;
and S4B2, when the discharge quantity of the storage parts is equal to the corresponding volatilization quantity, controlling the first driving device to drive all the storage parts to rotate and switch to the next storage part in the clockwise direction or the anticlockwise direction.
In the embodiment, the discharging amount is directly obtained by arranging the weight sensor in the furnace body, and when the discharging amount is equal to the volatilization amount, the raw material output is stopped; because the discharge amount is obtained by weighing the weight sensor, the value of the discharge amount is relatively real and accurate, and therefore, the elements to be supplemented are supplemented more accurately.
