Description

Technical Field

[0001] The invention relates to the technical field of metallurgy, and in particular to a diversified metallurgical process physical simulation system and a test method. Background Art

[0002] The formation of new technologies and the development of new products are powerful driving forces for the development of the metallurgical industry, but this requires a series of experimental processes. If new process improvements, new equipment commissioning and new product development are carried out directly on the production line, it may seriously affect actual production and even cause huge economic losses. Therefore, most steel companies use physical simulation test devices to conduct preliminary research and development of processes and products. The results of physical simulation guide the formulation of production procedures, and the level of new processes or the quality of new products are judged by testing pilot products, and then industrial trial production is carried out. It can be seen that the physical simulation device of metallurgical processes plays an important role in process improvement and product development.

[0003] The physical simulation devices for metallurgical processes currently built can simulate and reproduce the actual production process, but the research objects are mainly limited to single metallurgical reactors such as blast furnaces, coke ovens or converters, or a key link or unit in the metallurgical process, resulting in significant differences between the test devices and large-scale, continuous actual production equipment, and making it difficult to apply the processes or technologies obtained from physical simulation in actual production. In addition, since most metallurgical processes are carried out under strong light, high temperature and other environments, most physical simulation test devices find it difficult to achieve real-time online observation and data collection of metallurgical processes, increasing the difficulty of developing new technologies, new processes and new products.

[0004] It is an inevitable trend for the future development of steel enterprises to use metallurgical process physical simulation equipment to develop a new generation of high-strength, corrosion-resistant, environmentally friendly steel materials and new technologies and processes with short processes and close to user needs. Summary of the invention

[0005] In order to solve the technical problems raised by the background technology, the present invention provides a diversified metallurgical process physical simulation system and test method, covering multiple metallurgical processes, which can realize comprehensive test simulation of the production process, and has the functions of three-dimensional visualization of the research process and real-time data collection. It is a metallurgical process research system with more complete functions and more advanced technology, which plays a role in communication, promotion and facilitation of process simulation, process control and process research. At the same time, the system and the method of use provide a test platform for the functional development and upgrading of production equipment, which is conducive to the transformation of new products, new processes, new technologies and new equipment into productivity as soon as possible, and has important guiding significance for actual production.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A diversified metallurgical process physical simulation system includes a vacuum subsystem, a circulating cooling subsystem, a charging subsystem, a heating subsystem, a data acquisition and processing subsystem, a power supply subsystem and a sample stage.

[0008] The heating subsystem includes a heating body, a heating furnace shell and a thermocouple. The heating body is fixed inside the heating furnace shell. The heating temperature of the heating body can reach 2000°C. The sample table is placed inside the heating furnace shell. The heating furnace shell is provided with observation windows in multiple directions. The spatial arrangement of the heating body and the geometric shape of the heating furnace shell do not affect the observation of the test sample placed on the sample table from the top of the vacuum chamber shell and from two directions perpendicular to each other in a plane parallel to the sample table. The thermocouple is used to measure the temperature at different positions in the heating furnace shell during the test.

[0009] The vacuum subsystem includes a vacuum chamber and a vacuum pipeline connected thereto. The heating subsystem is placed in the vacuum chamber of the vacuum subsystem. The loading subsystem is arranged outside the vacuum chamber and the test material is fed to the sample stage through the feeding pipeline.

[0010] The circulating cooling subsystem has a temperature regulating function and cools the vacuum chamber shell through a cooling water circulation pipeline.

[0011] The data acquisition and processing subsystem includes a light source, a CCD camera and a computer. The light source irradiates light to the sample placed on the sample stage through an observation window, which is used to observe the background light of the test sample during the test. Through the CCD cameras located in multiple directions of the vacuum chamber shell, the morphology of the test sample is observed at various angles through the observation window, realizing the observation of the sample in three-dimensional directions during the test, and the relevant information of the test process is recorded in real time by the computer.

[0012] Furthermore, the heating body is formed by two annular heating bodies connected in a cross manner, and the sample stage is placed in the center thereof. The cross-shaped annular structure of the annular heating bodies enables the CCD camera to observe the sample stage from all directions, and the heating uniformity is good.

[0013] Furthermore, the heating furnace shell is made of high temperature resistant material.

[0017] Furthermore, the circulating cooling subsystem includes a cooling water tank, which has a temperature regulation function and can regulate the temperature of the cooling water in the cooling water tank, vacuum chamber shell and cooling water pipeline according to the requirements of the physical simulation test of the metallurgical process to ensure the normal operation of the test equipment; the cooling water is driven by a circulating water pump to circulate in the cooling water tank, vacuum chamber shell and cooling water pipeline.

[0018] Furthermore, the loading subsystem includes a loading bin, a bin switch and a feeding pipe. The loading bin is used to store materials required for the test and is arranged in the upper space of the vacuum chamber shell. The test materials are released through the bin switch and the feeding pipe. The test materials released from the loading bin fall onto the sample table. Multiple loading subsystems can be arranged circumferentially in the upper space of the vacuum chamber shell 28.

[0019] Furthermore, the power supply subsystem provides power supply to the diversified metallurgical process physical simulation system; through the PID multi-group program control method, the heating temperature, heating speed and insulation time of the heating body are controlled.

[0020] The simulation test method of a diversified metallurgical process physical simulation system comprises the following steps:

[0021] (1) Turn on the power supply system to ensure that all instruments and meters in the system are powered and in normal use;

[0022] (2) Open the circulating cooling subsystem to ensure that cooling water flows into the equipment and components that require cooling protection;

[0023] (3) Use the vacuum subsystem to perform vacuum pumping. If protective gas conditions are required, protective gas can be filled into the vacuum chamber after the vacuum pumping operation. If atmospheric conditions are required, the vacuum pumping operation can be ignored.

[0024] (4) Use the loading subsystem to fill and place the test materials in the loading bin and sample table respectively;

[0025] (5) Turn on the heating subsystem, set the heating system and heating program for heating, heat preservation and cooling, turn on the power and start heating;

[0026] (6) Within a set time before the heating subsystem starts working or the test temperature is about to be reached, turn on the data acquisition and processing subsystem, and select to continue collecting, transmitting and saving test data until the end of the test or at different time periods;

[0027] (7) After the test, turn off the data acquisition and processing subsystem and the heating subsystem, wait for the system to cool down to room temperature, and for the test under vacuum conditions, turn off the vacuum subsystem to release the vacuum environment. For the test under protective atmosphere conditions, release the protective atmosphere environment. For the test under atmospheric environment conditions, no other operations are required, and then take out the test sample;

[0028] (8) Turn off the power supply system and the test ends.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1) The diversified metallurgical process physical simulation system and test method of the present invention covers multiple metallurgical processes, can realize comprehensive test simulation of the production process, and has the functions of three-dimensional visualization of the research process and real-time data collection. It is a metallurgical process research system with more complete functions and more advanced technology, which plays a role in communication, promotion and facilitation of process simulation, process control and process research. At the same time, the system and its use method provide a test platform for the functional development and upgrading of production equipment, which is conducive to the transformation of new products, new processes, new technologies and new equipment into productivity as soon as possible, and has important guiding significance for actual production;

DETAILED DESCRIPTION

[0036] The specific implementation modes provided by the present invention are described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the diversified metallurgical process physical simulation system of the present invention includes a vacuum subsystem, a circulating cooling subsystem, a charging subsystem, a heating subsystem, a data acquisition and processing subsystem, a power supply subsystem and a sample stage 25. Among them, the vacuum subsystem mainly includes a gas cylinder 1, a gas circuit switch 2, 4, 9, 10, a gas circuit pipeline 3, 5, 7, 12, a mechanical pump 6, a molecular pump 8, a vacuum chamber 27, and a vacuum chamber shell 32. The circulating cooling subsystem includes a cooling water tank 11, a circulating water pump 15, cooling water pipelines 16, 17, and cooling water 31. The charging subsystem includes a charging bin 18, a bin switch 19, and a feeding pipeline 22. The heating subsystem includes a heating furnace shell 28, a heating body 29, and thermocouples 36, 39. The data acquisition and processing subsystem includes a light source 14, an observation window 13, 20, 23, 24, 30, 38, a CCD camera 21, 40, a data transmission wire 33, 35, a computer 34, and a temperature recorder 37. The power supply subsystem mainly includes a wire 41 and a power supply cabinet 42 .

[0038] The vacuum subsystem can fill the vacuum chamber 27 with specific inert gas or other types of gas required for the metallurgical process physical simulation test through the gas cylinder 1, the gas circuit switch 2, and the gas circuit pipeline 3. The vacuum subsystem can evacuate the vacuum chamber 27 through the mechanical pump 6, the molecular pump 8, the gas circuit switches 4, 9, 10, and the gas circuit pipelines 5, 7, and 12. The maximum vacuum degree of the vacuum chamber 27 can reach 1.0×10 -5 Pa.

[0039] The cooling water tank 11 of the circulating cooling subsystem has a temperature adjustment function, and can adjust the temperature of the cooling water tank 11, the vacuum chamber shell 32, and the cooling water 31 in the cooling water pipes 16 and 17 according to the requirements of the metallurgical process physical simulation test to ensure the normal operation of the test equipment. The cooling water 31 is driven by the circulating water pump 15 to circulate in the cooling water tank 11, the vacuum chamber shell 32, and the cooling water pipes 16 and 17.

[0040] The loading bin 18 of the loading subsystem is mainly used to store materials required for the test, and is arranged in the upper space of the vacuum chamber housing 32. The test materials can be put in through the bin switch 19 and the feeding pipe 22, and the test materials put in by the loading bin 18 fall on the sample table 25. Multiple loading subsystems can be arranged circumferentially in the upper space of the vacuum chamber housing 32.

[0041] The heating body 29 of the heating subsystem is fixed inside the heating furnace shell 28. The maximum heating temperature of the heating body 29 can reach 2000°C. The spatial arrangement of the heating body 29 and the geometric shape of the heating furnace shell 28 do not affect the observation of the test sample placed on the sample stage 25 from the top of the vacuum chamber shell 32 and in two directions perpendicular to each other in the plane parallel to the sample stage 25. The heating furnace shell 29 is made of high temperature resistant material. Thermocouple 36 is arranged below the sample stage 25 near the test sample, and thermocouple 39 is arranged at a certain distance above the sample stage 25. Thermocouple 36 and thermocouple 39 are mainly used to measure the temperature at different positions in the heating furnace shell 29 during the test.

[0042] like Figure 2 As shown, the heating body 29 of this embodiment is formed by two annular heating bodies connected crosswise, and the sample stage 25 is placed in the center thereof. The cross-annular structure of the annular heating bodies enables the CCD cameras 21 and 40 to observe the sample stage 25 from all directions, and the heating uniformity is good.

[0043] The light source 14 of the data acquisition and processing subsystem can irradiate light to the sample placed on the sample stage 25 through the observation window 13, which is mainly used for observing the background light of the test sample during the test. By adjusting the brightness of the light source 14, it is convenient to observe the test sample more clearly. The CCD camera 21 is located directly above the vacuum chamber shell 32, and the top of the test sample can be observed through the observation window 20. The CCD camera 40 is located in a plane parallel to the sample stage 25, and the side morphology of the test sample can be observed through the observation window 38. In the plane parallel to the sample stage 25, the light source 14, the observation window 13, the observation window 24, the observation window 30, the observation window 38, the sample stage 25, and the CCD camera 40 are in the same direction, and are perpendicular to the direction of the CCD camera 21, the observation window 20, the observation window 23, and the sample stage 25. Therefore, the diversified metallurgical process physical simulation system can realize the observation of samples in the test process in three dimensions at the same time. The sample morphology observed by the CCD cameras 21 and 40 can be transmitted to the computer 34 in real time through the data transmission wires 33 and 35, and the relevant information of the test process can be recorded in real time by the computer 34. The temperatures at different positions measured by the thermocouples 36 and 39 can be recorded in real time by the temperature recorder 37.

[0044] The power cabinet 42 of the power supply subsystem provides power supply to the diversified metallurgical process physical simulation system through the wire 41. The power cabinet 42 can control the heating temperature, heating speed, insulation time, etc. of the heating body 29 through PID multi-group program control.

[0045] The diversified metallurgical process physical simulation system is easy to operate, and the specific usage methods can be converted according to different metallurgical processes. It has flexible and adjustable usage performance. The general usage process of the system is as follows: (1) Turn on the power supply subsystem to ensure that all instruments and meters in the system are powered on and used normally; (2) Turn on the circulating cooling subsystem to ensure that cooling water flows into the equipment and components that require cooling protection; (3) Use the vacuum subsystem to perform vacuum operations. If protective gas conditions are required, protective gas can be filled into the vacuum chamber after the vacuum operation. If atmospheric conditions are required, the vacuum operation can be ignored; (4) Use the loading subsystem to fill and place test materials in the loading bin and sample table respectively; (5) Turn on the heating subsystem, set the heating system and heating program for heating, heat preservation, and cooling, turn on the power, and start heating. Heat; (6) Before the heating subsystem starts working or the test temperature is about to be reached, turn on the data acquisition and processing subsystem, and select to continue until the end of the test or different time periods to collect, transmit and save the test data; (7) After the test is over, turn off the data acquisition and processing subsystem and the heating subsystem, and wait for the system to cool down to room temperature. For tests under vacuum conditions, turn off the vacuum subsystem to release the vacuum environment. For tests under protective atmosphere conditions, the protective atmosphere environment needs to be released. For tests under atmospheric environment conditions, no other operations are required, and then take out the test sample; (8) Turn off the power supply subsystem and the test is over.

[0046] Embodiment 1

[0047] When conducting a physical simulation test on the interaction between molten steel and the crystallizer during the continuous casting process, a copper plate sample with a regular hexahedron shape of 25mm×25mm×5mm was collected from the actual continuous casting crystallizer, and a steel material with a regular hexahedron shape of 5mm×5mm×5mm with a certain composition and size was placed in the center of the copper plate sample. The steel material and the copper plate sample were placed in the center of the upper surface of the sample table 25. The cooling water 31 in the cooling water tank 11 was passed into the cooling layer of the vacuum chamber shell 28 through the circulating water pump 15 to ensure stable operation of the equipment during the test. The vacuum chamber 27 was evacuated using the mechanical pump 6 and the molecular pump 8 until the vacuum required by the test reached 1.0×10 -4Pa, the heating body 29 is connected to the power supply cabinet 42 through the wire 41, and the heating and heat preservation operations are started. During the test, the light source 14, CCD cameras 21, 40 are turned on, and the interaction between the molten steel and the copper plate of the crystallizer during the test can be observed in three dimensions and the test data is recorded synchronously. The sample image and data are stored in the computer 34 through the data transmission wire. After the test, the power supply, light source 14, CCD cameras 21, 40, and computer 34 are turned off, and the heating furnace is cooled naturally. When the temperature drops to room temperature, the test sample is taken out from the vacuum chamber 27. Using this diversified metallurgical process physical simulation system, the physical simulation test research of the interaction between the molten steel and the crystallizer under the protective atmosphere and atmospheric environment conditions can also be realized. The test process is similar to the vacuum condition, and the difference lies in the opening and closing of the gas circuit switches 2, 4, 9, 10, and the opening and closing of the mechanical pump 6 and the molecular pump 8, which will not be described in detail here. By physically simulating the interaction between the molten steel and the crystallizer during the continuous casting process, the degree and law of the interaction between the molten steel and the crystallizer under different action times can be found.

[0048] Embodiment 2

[0049] When conducting a physical simulation test study on the hot-dip galvanizing process of applying galvanizing liquid on the surface of a cold-rolled steel plate, a cold-rolled steel plate with a regular hexahedron shape of 25mm×25mm×5mm was selected, and a pure zinc plate material with a regular hexahedron shape of 10mm×10mm×3mm was placed in the center of the steel plate sample. The steel plate material and the pure zinc plate sample were placed in the center of the upper surface of the sample table 25. The cooling water 31 in the cooling water tank 11 was passed into the cooling layer of the vacuum chamber shell 28 through the circulating water pump 15 to ensure stable operation of the equipment during the test. The vacuum chamber 27 was evacuated using the mechanical pump 6 and the molecular pump 8, and the vacuum required by the test was reached. 1.0×10 -3Pa, the heating body 29 is connected to the power supply cabinet 42 through the wire 41, and the heating and heat preservation operations are started. During the test, the light source 14, CCD cameras 21, 40 are turned on, and the flow state of zinc liquid on the surface of the steel plate material during the test can be observed in three dimensions and the test data can be recorded synchronously. The sample image and data are stored in the computer 34 through the data transmission wire. After the test, the power supply, light source 14, CCD cameras 21, 40, and computer 34 are turned off, and the heating furnace is cooled naturally. When the temperature drops to room temperature, the test sample is taken out from the vacuum chamber 27. This diversified metallurgical process physical simulation system can also be used to realize the physical simulation test research of the cold-rolled steel plate and zinc liquid hot-dip galvanizing process under protective atmosphere and atmospheric environment conditions. The test process is similar to the vacuum condition, except that the opening and closing of the gas circuit switches 2, 4, 9, 10, and the opening and closing of the mechanical pump 6 and the molecular pump 8 are not described in detail here. By physically simulating the hot-dip galvanizing process, we can discover the degree and law of the interaction between zinc liquid and steel plate under different action time, temperature and atmosphere conditions, which has important guiding significance for the formulation of advanced hot-dip galvanizing technology.
