Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides an automatic operation system for a submerged arc furnace, including a data acquisition system 1, a data processing system 2 and an automatic control system 3,

The electrical operating parameters collected by the data collection system include: electrode current, arc voltage, active power, operating resistance, electrode length, electrode feed depth, and the like.
The utility model discloses in the embodiment: the electrical operation parameters of the electrode feeding depth adopt an external magnetic field method, and a magnetic field signal generated outside the furnace body when the electrode works is measured through an electromagnetic sensor. Because the large current of the electrode during working can generate a magnetic field outside the furnace body, the magnetic field intensity can change due to the difference of the inserting depth of the electrode, a magnetic field signal is measured by the electromagnetic sensor, and the position of the electrode in the submerged arc furnace is obtained by utilizing the magnetic field. The electrode feed depth is analyzed over a period of time and is related to the smelting cycle, so that both automatic and manual operation must be blocked.
Further: and the electrode feeding depth is also verified by adjusting the reference magnetic impedance coefficient. The full-automatic operation system of the submerged arc furnace can display the electrode feeding depth in real time, but when the system is just put into operation, the electrode feeding depth needs to be checked, and the display value is matched with the actual value. If the displayed value and the actual value still have deviation after running for a period of time, the accuracy of measuring the electrode feeding depth can be improved by adjusting the reference magnetic impedance coefficient.

The data processing system 2 is used for carrying out modeling operation by utilizing the electric operation parameters, the submerged arc furnace setting parameters and the electric furnace transformer parameters acquired by the data acquisition system to obtain required furnace control parameters, and outputting control switching values to the automatic control system. In this embodiment: the data processing system adopts an industrial computer, and displays various electrical operation parameters through a display screen of the industrial computer. The intelligent data acquisition cabinet of the data acquisition system processes data into digital signals and uploads the digital signals to an industrial computer of the data processing system in real time. The industrial computer also has internet function for remote control. The utility model discloses in the embodiment, data processing system is equipped with instrument parameter setting module, three-phase curve module, manual accuse stove module, control value setting module and the debugging module of system management module, historical record module, single-phase curve module, data acquisition cabinet. The instrument parameter setting module of the data acquisition cabinet comprises an output module setting, an instrument range setting, an instrument address and an instrument communication test, can detect whether the communication of the instrument and the module installed on the whole data acquisition cabinet is normal or not, and can set the turn-off time and the address of the module.
The submerged arc furnace setting parameters are set through an instrument parameter setting module of the data acquisition cabinet, and include an upper active power limit, a lower active power limit, an electrode current allowable value, a longest pressure release time, a shortest pressure release time, an electrode shallow limit, an electrode deep limit, an electrode displacement uplink limit, an electrode displacement downlink limit, an electrode current density, an arc voltage control value, electrode consumption, a furnace transformer overload protection multiple, a pressure release one-time downward movement amount, an electrode length control value, standard resistivity, standard furnace discharge electric quantity and sectional control setting. In the automatic furnace control process, different parameters are set according to different furnace conditions, and the automatic operation system of the submerged arc furnace automatically controls the furnace according to the set electric operation parameters. The setting of the electrode current allowable value, the electrode feeding depth and the active power upper and lower limits is the key of the whole submerged arc furnace automatic operation system, because:
1. the active setting value is large, the electrode works shallow, the active setting is low, and the electrode works deep;
2. the electrode is deep, which is beneficial to thickening the solid material layer and reducing the heat dissipation of the furnace surface, but the power of the electrode is reduced too deeply, so that the yield is reduced, therefore, the reasonable upper and lower limits of the electrode are set to be very critical, and the working range of the electrode corresponding to the stage with good furnace condition can be found out from the historical curve, so that the working range of the electrode is used as the set value of the feeding depth of the electrode.
3. It is important to ensure that the bath temperature is high enough, to extend tapping time to increase furnace temperature, and to adjust tapping capacity or tapping time so that each furnace ladle is substantially full. For example, the ladle can be charged with 32 tons, and if the ladle is charged with 29 tons only in one furnace, the next furnace can be charged with 2 tons.
The setting principle of the upper and lower limits of the electrode feeding depth is that the difference between the upper and lower limits of the electrode feeding depth is 100-120 mm; when the furnace temperature is observed to be higher, the depth limit value is uniformly adjusted to be deeper, otherwise, the depth limit value is adjusted to be shallower. If the upper limit and the lower limit are set to be shallow, the active power is high, but the charge level temperature is higher, and the heat dissipation loss is large; otherwise, the power is low, and the power is gradually adjusted to a proper value according to the operation of a period of time.
The principle of automatic electrode adjustment is as follows:
the three-phase current is preferably leveled, when the maximum electrode current of one phase is greater than an allowable value, the three-phase electrode is synchronously lifted, when the average depth of the three phases is less than the upper limit value of the depth, the electrode is not lifted any more, and at the moment, if the electrode current is still excessive, the three-phase voltage is synchronously reduced;
when the electrode current is less than 0.97 times of the allowable value, the three-phase synchronous lower electrode is not used until the lower limit value of the depth is reached, and when the current is still small, the three-phase synchronous boosting is carried out.
In the current leveling process, the deviation between the maximum electrode feeding depth and the minimum electrode feeding depth is not greater than 120mm, the deviation between the maximum electrode feeding depth and the minimum electrode feeding depth is 100mm, for example, the shallowest electrode feeding depth of a certain electrode is 1100, if it is determined that the deepest phase requires the downward insertion of the leveling current, but the maximum feeding depth exceeds 1200mm, the downward insertion cannot be performed at this time.
The electrode current allowable value setting principle is as follows: the method is characterized in that a larger allowable value is set as much as possible on the premise of ensuring that no electrode fault occurs, the safe allowable value does not need to be changed to a smaller value after verification, the allowable value is set to be higher, the active power is higher but is limited by water temperature, the value is determined according to the judgment that the water temperature is not over high and the electrode is not over burnt, and the allowable value of general current is not changed as much as possible after being set (when no low-voltage compensation is adopted, the allowable current of the electrode needs to be set in consideration of furnace secondary current and primary current not over-load).
The active power upper and lower limits are set according to the principle: when the actual active power exceeds the upper limit active power set value, the voltage is automatically reduced; when the active power is lower than the lower limit active power set value, and the electrode current is smaller than 0.98 times of the allowable value, the voltage is boosted.
And the three-phase curve module of the data processing system 2 is used for checking a three-phase electrode operation curve at any time period in one year, wherein the three-phase electrode operation curve comprises depth displacement, electrode depth, electrode displacement, electrode current, resistivity and electrode power.
The single-phase curve module of the data processing system 2 is used for checking the operation curves of current, power, electrode depth, operation resistance and the like at any time interval in a single-phase year.
And the manual furnace control module is used for completing electrode lifting, transformer gear adjustment and electrode pressure releasing operation of the submerged arc furnace through a full-automatic submerged arc furnace operation system in a manual furnace control state. The display screen of the industrial computer also displays the pressure release amount and consumption of each phase of electrode, the electric quantity for the furnace and the eye plugging time.
The industrial computer can also automatically adjust the display picture according to the resolution of the display, so that the whole designed interface is completely displayed on different screens.
The production of each furnace is logged in the data processing system 2 so that the system performs an energy consumption analysis of each furnace. If the output of the single furnace is forgotten to be input or the input is incorrect during the operation period, the output and the smelting time can be modified, and after the modification is completed, the automatic operating system of the submerged arc furnace can automatically perform data operation again to obtain new energy consumption data of the single furnace.
When the automatic operation system of the submerged arc furnace is restarted in operation, please record the electrode feeding depth before the program is stopped, check according to the depth after restarting or check according to the actually measured depth, and input the electric quantity for the furnace.
When the automatic operation system of the submerged arc furnace does not need to be started again for a long time, the submerged arc furnace is manually operated for one day, the eyes are required to be blocked on time in the period, and the electrode feeding depth can be automatically checked to be a more accurate value gradually after one day.
When the electrode is confirmed to be shallow, the upper limit and the lower limit of the active power are required to be adjusted to be small because the molten pool is moved upwards, the upper limit and the lower limit of the electrode are gradually adjusted downwards, and the upper limit and the lower limit of the electrode are adjusted to be not too large step by step, and the lower limit of the electrode can be lowered to the bottom line if the furnace can reach the bottom line, the lower limit of the next furnace is increased by 20, and the electrode is gradually raised. This process may take several days, and after the electrodes are lowered into position, the active power is stepped up, each increment being based on the average depth of the electrodes which can be lowered to the bottom line.
Possibly; the data processing system 2 is used for debugging all electrical operation parameters of the automatic submerged arc furnace operation system. The debugging module is used for debugging, so that field engineering personnel can conveniently check all parameters of the full-automatic operating system of the whole submerged arc furnace.
Further: the data processing system is also used for dynamically displaying the position of the electrode in the furnace in the form of animation. The electrode adopts animation display in the stove position, the staff of being convenient for observes the electrode degree of depth in real time.

The data processing system can analyze the power consumption of each shift every day, the ton power consumption and the corresponding furnace control parameters, and find out the optimal furnace control parameters. Thereby improving the power of the automatic operating system of the submerged arc furnace and reducing the energy consumption.
And the automatic control system 3 is used for automatically controlling the electrode lifting, the electrode pressure releasing and the transformer gear adjustment according to the received data of the data processing system. The embodiment of the utility model provides an in, automatic control system comprises digital analog conversion relay and switch board, and the switch board can use current switch board. Specifically, the automatic operation system of the submerged arc furnace automatically controls the electrode to ascend and descend according to the furnace entering active power and the electrode current, so that the electrode current reaches three-phase balance, and the furnace entering active power is controlled within a set range. The automatic operation system of the submerged arc furnace is used for carrying out pressure discharge once in a short time according to the fact that the length of the electrode is calculated and is smaller than a set value; if the length of the electrode is greater than the set value, the electrode is pressed and released once according to a longer time, in the embodiment, the longer time is 120 minutes, and the shorter time is 50 minutes, so that the length of the electrode is controlled within the set range. The automatic operation system of the submerged arc furnace automatically controls the gear lifting of the transformer according to the furnace entering active power and the electrode current, so that the furnace entering active power is in a set range; the transformer is not overloaded; the electrode current is not overloaded.
The automatic control principle of the automatic operating system is as follows:
1. when the electrode is at the top and the electrode is still large,
if the furnace temperature is not high, the upper limit value of the depth is slightly reduced, and the electrode is continuously lifted instead of being depressurized.
If the furnace temperature is higher than normal, the electrode is too shallow, and the voltage and the load can be reduced;
2. and the electrode is slowly put down, the electrode can be put down when the current is small, but the electrode is put down, and at the moment, if the electrode does not exceed the intermediate value, the electric quantity of the electrode can be increased, so that the electrode can be put down continuously.
3. As long as the current is small enough and the active power is large enough, the electrodes can be struggled to be inserted more, and even if the electrodes are lowered to the lower limit, the lower limit feeding depth can be adjusted to be large.
4. The electrode is not required to be lifted in the electrode lifting stage, the electrode cannot be lifted in the lower electrode stage, the electrode is lifted because the current exceeds, if the voltage is reduced and the active power is reduced, only one principle needs to be grasped, and the electrode is required to work in the deep position below the middle line of at least the set upper limit and the set lower limit in the latter half of smelting. Because the furnace temperature in the latter half section is highest, the thicker the required insulating layer is.
5. The electrode is shallower than the control range and the current is large; the electrode can not be lifted, and only the voltage can be reduced.
6. The electrode is deeper than the control range and the current is small; the electrode can not be inserted, and only the voltage can be boosted.

If the user wants to start in advance, the electric quantity at the starting point is reduced, and if the user wants to finish the process a little later, the electric quantity at the finishing point is increased.
Fifthly, when the active power is larger than the upper limit value, the voltage is reduced, and when the power is not high, the upper limit value of the active power is reduced, otherwise, the upper limit value of the active power is increased.
