Description

Technical Field

[0001] The invention belongs to the technical field of metallurgy, and in particular relates to an intelligent iron receiving method for a torpedo tank. Background Art

[0002] In the blast furnace ironmaking process, the molten iron is mostly transported in torpedo cans. The main operation process includes: after the torpedo can enters the workstation, check whether the torpedo can meets the iron receiving requirements, adjust the tilting angle of the swing nozzle to ensure that the molten iron enters the can safely, send a can signal, and tow away the full torpedo can. For many companies, the above operation process still relies on manual operation, which not only has low production efficiency, but also has high labor intensity and safety hazards.

[0003] The Chinese patent specification discloses a method and system for automatic measurement of molten iron in a torpedo tank (publication number CN103824166A), which includes the following steps: filling molten iron into a tank; forecasting by sampling personnel; matching the weight of the tank car and the tank number; confirming whether the matching information is correct; confirming receipt; matching the tare weight and the tank number; calculating the net weight; and saving all data information to the server. This invention patent application realizes the automatic iron receiving of the torpedo tank by combining the automatic measurement of the molten iron in the torpedo tank with images.

[0004] The Chinese patent specification also discloses an automatic safety system for molten iron filling and its operating method (publication number CN104003343B), and specifically discloses the following contents: it includes a molten iron tank car and an operator station arranged above the molten iron tank car and close to the molten iron gate. The molten iron tank car and the operator station are wirelessly connected through a data transmission device, and the displayed data is used to determine whether to align with the molten iron outlet and when to open or close the molten iron gate. This invention patent realizes the automatic iron receiving of the torpedo tank by combining a distance measuring sensor with the weighing of the molten iron tank car.

[0005] Although the above invention can realize the automatic iron receiving of torpedo tanks, reduce safety risks and save human resources, its iron receiving method is simple and crude, and the efficiency of iron receiving has not been substantially improved. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] The present invention proposes an intelligent iron receiving method for a torpedo tank, and its purpose is to solve the problems of low iron receiving efficiency, high safety risk and high manpower consumption of the torpedo tank through the application of an intelligent system.

[0008] 2. Technical Solution

[0009] In order to achieve the above object, the present invention adopts the following technical solutions.

[0010] The monitoring center receives the torpedo tank status image, molten iron level data, and track scale weighing data from the iron receiving site. After analysis and processing, it sends work instructions to the nozzle and signal generator at the iron receiving site, so as to realize the alternating iron receiving of two torpedo tanks on different tracks. The specific steps include:

[0011] 1) Detect whether the torpedo tank has reached the workstation. If not, send a tank-checking signal to perform tank-checking operations on the torpedo tank that has not reached the workstation;

[0012] 2) Check whether the torpedo tank meets the iron-bearing conditions. If not, send a tank replacement signal to replace the torpedo tank that does not meet the iron-bearing conditions;

[0013] 3) Select a torpedo tank with a lower molten iron level to test the iron and observe whether the molten iron can enter the tank. If not, send a tank change signal and go to step 4); if yes, go to step 5);

[0014] 4) Select a torpedo tank with a higher molten iron level to receive iron, and observe whether the molten iron enters the tank safely. If not, send a blocking signal to cut off the outflow of molten iron, and then send a tank change signal, and return to step 1); if yes, go to step 7);

[0015] 5) Select a torpedo tank with a higher molten iron level to receive the iron and observe whether the molten iron enters the tank safely. If not, proceed to step 6); if yes, proceed to step 7);

[0016] 6) Send a signal to change the tank, and at the same time, select another torpedo tank to receive the iron;

[0017] 7) Continue to add iron until the torpedo tank is full;

[0018] 8) Send out a tank report signal;

[0019] 9) Choose another torpedo tank to receive iron;

[0020] 10) Tow the full torpedo tanks away from the iron receiving site;

[0021] 11) Return to step 1) and repeat this cycle.

[0022] Furthermore, the arrival at the work station means that the molten iron level in the torpedo tank is higher than 1.0m and the track scale weighs more than 200 tons.

[0023] Furthermore, the iron-receiving condition means that the image diameter of the torpedo tank filling port is more than 96% of the actual diameter, and the molten iron level in the torpedo tank is lower than 3.65m.

[0024] Furthermore, the tank-checking signal is issued when the molten iron level in the torpedo tank is lower than 0.1m and the track scale weighs less than 10 tons; the tank-reporting signal is issued when the molten iron level in the torpedo tank reaches 3.65m or the track scale weighs 580 tons;

[0025] Furthermore, the torpedo tank status image is collected by a camera and transmitted to an image display screen through an application server for display.

[0026] Furthermore, the molten iron level data is collected by a liquid level sensor and transmitted to a liquid level display meter for display via an application server.

[0027] Furthermore, the weighing data of the track scale is collected by the track scale sensor and transmitted to the weighing display through the application server.

[0028] Furthermore, the torpedo tank receives iron by the central controller sending out an iron receiving instruction, which is executed by the intermediate module to adjust the swing of the flow nozzle so that the iron outlet is docked with the tank mouth of the torpedo tank, and the molten iron is injected into the torpedo tank.

[0029] Furthermore, the tank matching signal, tank changing signal, port blocking signal and tank reporting signal are all sent out by a signal generator, and the signal generator is connected to an intermediate module, and the intermediate module executes the signal instruction from the central controller.

[0030] Furthermore, the central controller analyzes and processes the information from the application server and issues a reception instruction or a signal instruction.

[0031] 3. Beneficial Effects

[0032] The invention discloses an intelligent iron receiving method for a torpedo tank. By applying an intelligent system, the invention effectively solves the problems of low iron receiving efficiency, great safety risk and high manpower consumption of the torpedo tank, thereby improving production efficiency, avoiding safety hazards and saving human resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 The present invention is a flow chart of the intelligent iron receiving method for a torpedo tank.

[0034] Figure 2 It is the principle diagram of the intelligent system of the present invention. DETAILED DESCRIPTION

[0035] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings to facilitate a clearer understanding for those skilled in the art.

[0036] Example

[0037] like Figure 1 , Figure 2 As shown, the present invention specifically comprises the following steps:

[0038] 1) Detect whether the torpedo tank has reached the workstation. If not, send a tank-checking signal to perform tank-checking operations on the torpedo tank that has not reached the workstation;

[0039] 2) Check whether the torpedo tank meets the iron-bearing conditions. If not, send a tank replacement signal to replace the torpedo tank that does not meet the iron-bearing conditions;

[0040] 3) Select a torpedo tank with a lower molten iron level to test the iron and observe whether the molten iron can enter the tank. If not, send a tank change signal and go to step 4); if yes, go to step 5);

[0041] The purpose of selecting a torpedo tank with a lower molten iron level to receive iron is to allow the torpedo tank with a higher molten iron level to receive iron first. Only when the torpedo tank with a higher molten iron level cannot receive iron, the torpedo tank with a lower molten iron level will be selected to receive iron. This can be seen from the following steps.

[0042] 4) Select a torpedo tank with a higher molten iron level to receive iron, and observe whether the molten iron enters the tank safely. If not, send a blocking signal to cut off the outflow of molten iron, and then send a tank change signal, and return to step 1); if yes, go to step 7);

[0043] 5) Select a torpedo tank with a higher molten iron level to receive the iron and observe whether the molten iron enters the tank safely. If not, proceed to step 6); if yes, proceed to step 7);

[0044] After the torpedo tank arrives at the steel plant, the molten iron in the torpedo tank may not be used up at one time, but it is not enough for another converter. Therefore, the torpedo tank can only be loaded with the remaining molten iron and return to the iron receiving site to continue receiving iron. In this case, the torpedo tank with a higher molten iron level is selected to receive iron first. There are three considerations: one is for production safety, the second is to save energy, and the third is to improve the efficiency of iron receiving.

[0045] For example: one torpedo tank is empty and needs 50 minutes to be filled with molten iron, while the other torpedo tank is half filled with molten iron and needs 25 minutes to be filled with molten iron. If the empty tank (low molten iron level) is filled first, and the empty tank is filled, and then the torpedo tank with half molten iron (high molten iron level) is filled, the torpedo tank can be filled in only 25 minutes. Due to the short time, the new torpedo tank has not arrived after the previous torpedo tank full of molten iron is pulled away, which affects the continuous operation of the torpedo tank receiving iron and reduces the efficiency of receiving iron; it may even force the blast furnace to block the iron mouth and cause production accidents; if the empty tank is filled first, the torpedo tank with a higher molten iron level will wait for a long time to be filled, and the molten iron in the tank will be greatly cooled, increasing the energy consumption of converter steelmaking.

[0046] If the torpedo tank that is half full of molten iron (the one with a high molten iron level) is filled first, it will only take 25 minutes to fill it up and take it away. Then the empty tank (the one with a low molten iron level) will take 50 minutes to fill it up, which is a long time, leaving ample time for the new torpedo tank to arrive.

[0047] 6) Send a signal to change the tank, and at the same time, select another torpedo tank to receive the iron;

[0048] 7) Continue to add iron until the torpedo tank is full;

[0049] 8) Send out a tank report signal;

[0050] 9) Choose another torpedo tank to receive iron;

[0051] 10) Tow the full torpedo tanks away from the iron receiving site;

[0052] 11) Return to step 1) and repeat this cycle.

[0053] Furthermore, the arrival at the work station means that the molten iron level in the torpedo tank is higher than 1.0m and the track scale weighs more than 200 tons.

[0054] Furthermore, the iron-receiving condition means that the image diameter of the torpedo tank filling port is more than 96% of the actual diameter, and the molten iron level in the torpedo tank is lower than 3.65m.

[0055] Furthermore, the tank-checking signal is issued when the molten iron level in the torpedo tank is lower than 0.1m and the track scale weighs less than 10 tons; the tank-reporting signal is issued when the molten iron level in the torpedo tank reaches 3.65m or the track scale weighs 580 tons;

[0056] Furthermore, the torpedo tank status image is collected by a camera and transmitted to an image display screen through an application server for display.

[0057] Furthermore, the molten iron level data is collected by a liquid level sensor and transmitted to a liquid level display meter for display via an application server.

[0058] Furthermore, the weighing data of the track scale is collected by the track scale sensor and transmitted to the weighing display through the application server.

[0059] Furthermore, the torpedo tank receives iron by the central controller sending out an iron receiving instruction, which is executed by the intermediate module to adjust the swing of the flow nozzle so that the iron outlet is docked with the tank mouth of the torpedo tank, and the molten iron is injected into the torpedo tank.

[0060] Furthermore, the tank matching signal, tank changing signal, port blocking signal and tank reporting signal are all sent out by a signal generator, and the signal generator is connected to an intermediate module, and the intermediate module executes the signal instruction from the central controller.

[0061] Furthermore, the central controller analyzes and processes the information from the application server and issues a reception instruction or a signal instruction.

[0062] According to the torpedo tank status image, molten iron level data and track scale weighing data, the central controller sends working instructions to the nozzle and signal generator at the iron receiving site to optimize the iron receiving process and method of the torpedo tank, thereby realizing accurate alternating iron receiving of two torpedo tanks on different tracks.

[0063] The invention discloses an intelligent iron receiving method for a torpedo tank. By applying an intelligent system, the invention effectively solves the problems of low iron receiving efficiency, great safety risk and high manpower consumption of the torpedo tank, thereby improving production efficiency, avoiding safety hazards and saving human resources.

[0064] The present invention is not limited to the above-mentioned specific implementation modes, and various improvements made by those skilled in the art to the technical solutions according to the concept of the present invention shall all fall within the scope of protection claimed by the present invention.
