Description

Technical Field

[0001] This invention relates to the field of steelmaking testing technology, specifically to a steel testing device and a temperature sampling method. Background Technology

[0002] In the refining process of steel metallurgy, accurate temperature measurement and composition analysis of molten steel are required to guide subsequent process operations and ensure the quality of the final product. Currently, integrated temperature measurement and sampling devices are widely used, which integrate the temperature measuring head and the sampling head into one unit, completing temperature measurement and sampling simultaneously in a single operation.

[0003] However, existing integrated temperature measurement and sampling devices have a significant drawback: after each measurement and sampling, residual molten steel solidifies on the inner wall of the sampling head and the surface of the temperature measuring head, forming solid slag and oxides. If these residues are not removed, they will severely affect the accuracy of subsequent measurements, leading to temperature data deviations and distorted composition analysis. Currently, cleaning mainly relies on manual labor, which is not only inefficient and labor-intensive but also difficult to perform in a timely manner, prolonging equipment downtime and disrupting production rhythm.

[0004] Therefore, there is an urgent need for an integrated device that can automatically and efficiently clean the temperature measuring head and the sampling head. Summary of the Invention

S3: After temperature measurement and sampling are completed, the sampling head and the temperature measuring head are raised. Then the rotating component is started, driving the temperature measurement and sampling component and the cleaning component to rotate and move to directly above the sample pot. S4: Activate the cleaning component to rotate it, and clean the surfaces of the sampling head and the temperature measuring head.

[0014] As one embodiment, the temperature sampling assembly includes: a cylinder, a push rod, a fixing block, a sampling head, and a temperature measuring head; In step S4, activating the cleaning assembly to rotate and simultaneously clean the surfaces of the sampling head and the temperature measuring head further includes the following steps: The cylinder is started synchronously to drive the sampling head and temperature measuring head to reciprocate so that the cleaning component can perform cleaning.

[0015] As one implementation, after S3 and before S4, the following is also included: The cylinder is activated, driving the push rod to move downwards, so that the sampling head is aligned with the sample pot and releases the molten steel sample collected inside into the sample pot.

[0026] According to one embodiment of the present invention, a molten steel testing device is provided. This device is mainly used in the steel metallurgical refining process to perform rapid and accurate temperature measurement and sample collection of molten steel, and can automatically clean the measuring components to ensure data accuracy and continuous operation of the equipment. The following is in conjunction with... Figures 1 to 5 The steel molten metal testing device will be described.

[0027] The molten steel detection device in this embodiment mainly includes a rotating assembly 3, a temperature-measuring and sampling assembly 4 and a cleaning assembly 38 disposed on the rotating assembly 3, a refining pot 5, and a sample pot 6. The rotating assembly 3 drives the temperature-measuring and sampling assembly 4 and the cleaning assembly 38 to move between a first position and a second position. When in the first position, the temperature-measuring and sampling assembly 4 performs temperature measurement and sample collection on the molten steel. When in the second position, the cleaning assembly 38 cleans the temperature-measuring and sampling assembly 4. The refining pot 5 is disposed below the first position and is used to hold the molten steel to be tested. The sample pot 6 is disposed to one side of the second position and is used to receive and cool the collected molten steel sample. When in the first position, the temperature-measuring and sampling assembly 4 can perform temperature measurement and sampling on the molten steel in the refining pot 5; when in the second position, the cleaning assembly 38 can clean the temperature-measuring and sampling assembly 4, and the temperature-measuring and sampling assembly 4 can deliver the sample to the sample pot 6.

[0028] In this embodiment, the stability and vibration resistance of the entire device during operation can be ensured by fixing the rotating component 3 to the base 1. The bottom of the base 1 can be fixed to the working platform with anchor bolts. A shell 2 is fixedly connected to the top of the base 1. The shell 2 is typically welded or assembled from steel plates to form a protective cover, serving to isolate and protect against external dust and splashed molten steel. The shell 2 also serves as a mounting base for multiple components. The refining pot 5 is fixed to the left side of the base 1 with bolts. It is lined with refractory material and encased in a steel shell, providing insulation. The sample pot 6 is installed on the top right side of the shell 2, made of copper alloy, and has internal cooling channels to accelerate sample cooling. The rotating component 3 is responsible for switching the temperature measuring and sampling component 4 and the cleaning component 38 between the first and second positions, corresponding to the positions of the refining pot 5 and the sample pot 6, respectively. The temperature measuring and sampling component 4 senses the temperature of the molten steel and acquires the sample, while the cleaning component 38 ensures the cleanliness of its working interface.

[0029] In this embodiment, the rotating assembly 3 includes: a first motor 31, a first drive shaft 32 disposed at the output end of the first motor 31, a first driving gear 33 disposed on the first drive shaft 32, a driven rod 34 rotatably disposed inside the housing 2, and a first driven gear 35 fixedly sleeved on the driven rod 34 and meshing with the first driving gear 33. The first motor 31 is fixedly connected to the top of the housing 2. A base plate 36 is fixedly connected to the driven rod 34, and a top plate 37 is fixedly connected to the top of the base plate 36. The base plate 36 and the top plate 37 jointly support and accommodate the temperature sampling assembly 4 and the cleaning assembly 38. The first motor 31 of the rotating assembly 3 is mounted on a motor mount on the top of the housing 2 via a flange. The motor mount is equipped with vibration damping pads to reduce operating noise. The surface of the first drive shaft 32 is subjected to high-frequency quenching to improve wear resistance. The first drive shaft 32 is directly connected to the output shaft of the first motor 31 via a coupling. The driven rod 34 adopts a hollow shaft structure, which ensures strength while reducing weight, and its outer surface is rust-proofed to extend its service life. When the first motor 31 starts, it drives the first driving gear 33 to rotate via the first drive shaft 32. The first driving gear 33 drives the first driven gear 35 to rotate, thereby driving the driven rod 34 to rotate. A base plate 36 is fixedly connected to the outside of the driven rod 34, and the base plate 36 rotates with the rotation of the driven rod 34. A top plate 37 is fixedly connected to the top of the base plate 36, and the top plate 37 and the base plate 36 together form a stable platform structure. A cleaning component 38 is installed inside the top plate 37, and the cleaning component 38 moves its position as the platform rotates. The main function of the rotating component 3 is to drive the temperature measurement and sampling component and the cleaning component to move between different positions, realizing the switching of functions. The rotational movement of the rotating component enables the device to efficiently switch between different working positions, improving work efficiency. The structure of the rotating component has the characteristics of smooth and precise transmission, ensuring that each component can be accurately aligned during rotation. In this invention, the rotating component 3 can be driven by various methods, such as, but not limited to, the gear transmission method in the above embodiments, or by belt transmission, chain transmission, or direct motor-driven rotating arm, as long as the temperature sampling component 4 and the cleaning component 38 can move between the first position and the second position.

[0030] Specifically, the cleaning component 38 has a second motor 381, which is fixedly connected to the top of the top plate 37, serving as the power support for the cleaning mechanism. A second drive shaft 382 is fixedly connected to the drive end of the second motor 381, transmitting the motor's rotational power. A second drive gear 383 is fixedly connected to the outside of the second drive shaft 382, ​​driving a second driven gear 384 to rotate via meshing transmission. A rotating block 385 is rotatably connected inside the base plate 36, and a second driven gear 384 is fixedly connected to the top of the rotating block 385. The second driven gear 384 meshes with the second drive gear 383, forming a gear transmission pair. When the second motor 381 starts, it drives the second drive gear 383 to rotate via the second drive shaft 382, ​​which in turn drives the second driven gear 384 to rotate, thereby causing the rotating block 385 to rotate. A brush 386 is fixedly connected to the bottom of the rotating block 385. The brush 386 rotates with the rotating block 385, cleaning other components. The main function of the cleaning component 38 is to automatically clean the used components and remove any attached residue after the temperature sampling operation. Automatic cleaning avoids the inconvenience of manual cleaning and improves the automation level and work efficiency of the equipment. The material and shape of the brush 386 are selected according to the characteristics of the cleaning object to ensure cleaning effect without damaging the cleaned parts. The rotating block 385 is supported on the base plate 36 by bearings, ensuring the stability and reliability of rotation. The cleaning mechanism ensures that the cleaned parts are thoroughly cleaned. The second drive shaft 382 ensures the stability of power transmission. The cooperation between the cleaning component and the rotating component allows the device to perform cleaning operations immediately after temperature sampling, greatly shortening the operation cycle.

[0031] Specifically, the temperature sampling component 4 is mounted on the rotating component 3 and changes position as the rotating component 3 moves. The temperature sampling component 4 includes a cylinder 41, which is fixedly connected to the top of the top plate 37. A push rod 42 is fixedly connected to the drive end of the cylinder 41. A fixing block 43 is fixedly connected to the bottom of the push rod 42, and a sampling head 44 is fixedly connected to the bottom of the fixing block 43. The sampling head 44 is used to collect samples from the molten steel. A temperature measuring head 45 is also fixedly connected to the bottom of the fixing block 43, used to measure the temperature of the molten steel. The main function of the temperature sampling component 4 is to simultaneously perform the temperature measurement of the molten steel and sample collection. Synchronous operation improves work efficiency and ensures the consistency of temperature and sample data. The cylinder 41 drives the fixing block 43 and its sampling head 44 and temperature measuring head 45 to move linearly via the push rod 42, realizing the actions of immersion in molten steel and lifting. The fixing block 43 ensures the accurate positioning and stable installation of the sampling head 44 and temperature measuring head 45. The sampling head 44 is made of materials and style suitable for molten steel sampling, enabling effective collection of representative samples. The temperature measuring head 45 uses a sensor suitable for high-temperature measurement, allowing for rapid and accurate measurement of the molten steel temperature. The structure of the temperature measuring and sampling assembly meets the requirements for use in high-temperature environments, and the materials and structures of each component have been specially selected and processed. The motion guide design of the push rod 42 ensures the accuracy of the motion trajectory, avoiding skewness and jamming. The connection between the fixing block 43 and the push rod 42 is firm and reliable, ensuring that it will not loosen during movement.

[0032] Specifically, the top end of the driven rod 34 is rotatably connected to the inside of the top plate 37 via a first bearing, which ensures the stability and smoothness of the driven rod 34 during rotation. The first bearing ensures the long-term reliable operation of the driven rod 34. The bottom end of the driven rod 34 is rotatably connected to the inside of the base 1 via a second bearing, forming a structure with support at both ends. The bearings effectively distribute the load, reducing vibration and deformation. Supported by the bearings at both ends, the driven rod 34 can rotate smoothly, ensuring the operational accuracy of the entire rotating mechanism. The sealed design of the bearings prevents the intrusion of dust and impurities, extending its service life. This support structure design fully considers various working conditions in actual use, ensuring stable performance during long-term operation.

[0033] Specifically, two brushes 386 are used, simultaneously addressing the cleaning needs of different components. The two brushes 386 correspond to the sampling head 44 and the temperature measuring head 45, respectively, ensuring effective cleaning of each component. The brushes 386 and the sampling head 44 and temperature measuring head 45 ensure full contact with the surfaces being cleaned during the cleaning process. The brushes 386 maintain a specific relative position to the components being cleaned for optimal cleaning results. The two brushes 386 may employ different materials and structural designs to adapt to the cleaning requirements of different components. The brush corresponding to the sampling head 44 may be designed to penetrate deep into the interior for cleaning, while the brush corresponding to the temperature measuring head 45 may focus more on surface cleaning. The brushes 386 are fixed in a detachable connection structure for ease of replacement and maintenance. The materials used for the brushes 386 are selected based on high temperature resistance and abrasion resistance, ensuring stable performance even in harsh working environments. The dual-brush design significantly improves cleaning efficiency, enabling the device to complete cleaning operations in a short time.

[0034] Specifically, the bottom end of the first drive shaft 32 is rotatably connected to the interior of the base 1 via a third bearing. The third bearing ensures stable operation of the first drive shaft 32 under various working conditions, reduces vibration and deformation during rotation, and improves transmission accuracy. The use of the third bearing extends the service life of the first drive shaft 32 and reduces maintenance requirements. The bottom end of the second drive shaft 382 is rotatably connected to the interior of the base plate 36 via a fourth bearing, which provides a stable center of rotation for the second drive shaft 382. The fourth bearing ensures the long-term reliability of the second drive shaft 382. The fourth bearing guarantees the stability of the second drive shaft 382 during high-speed rotation, reducing vibration and noise. The fourth bearing enables the second drive shaft 382 to accurately transmit power, ensuring the normal operation of the cleaning assembly 38.

[0035] Specifically, the push rod 42 is slidably disposed inside the top plate 37 and the second driven gear 384, and the guiding design ensures the stability of the push rod 42 during movement. The guide portion inside the top plate 37 ensures that the push rod 42 can slide smoothly without jamming. The double-guided design effectively prevents the push rod 42 from deviating during movement, ensuring movement accuracy. The guiding structure enables the push rod 42 to accurately transmit the power of the cylinder to the actuator, ensuring operational reliability.

[0036] Specifically, the center of the second driven gear 384 has a through hole for the push rod 42 to pass through, so that the push rod 42 can pass through the second driven gear 384 without affecting its rotational movement.

[0037] This embodiment provides a method for measuring and sampling molten steel temperature using the above-described device, including the following steps: S1: Move the temperature measuring and sampling component 4 directly above the refining pot 5 by rotating component 3; S2: Activate the temperature sampling component 4, so that the sampling head 44 and the temperature measuring head 45 in the temperature sampling component 4 are simultaneously immersed in the molten steel in the refining pot 5 to carry out sampling and temperature measurement. S3: After temperature measurement and sampling are completed, the sampling head 44 and the temperature measuring head 45 are raised. Then the rotating component 3 is started, driving the temperature measurement and sampling component 4 and the cleaning component 38 to rotate and move to directly above the sample pot. S4: Activate the cleaning component 38 to rotate it, and clean the surfaces of the sampling head 44 and the temperature measuring head 45 at the same time.

[0038] In step S4, when the cleaning component 38 is activated to rotate the brush 386 to clean the surfaces of the sampling head 44 and the temperature measuring head 45, the cylinder 41 in the temperature measuring and sampling component 4 is also activated simultaneously, driving the push rod 42 to drive the fixed block 43 and the sampling head 44 and the temperature measuring head 45 on it to perform precise reciprocating motion; the reciprocating motion allows the sampling head 44 and the temperature measuring head 45 to contact the rotating brush 386 at multiple angles and directions, which not only improves the cleaning efficiency, but also effectively removes residual steel slag in hard-to-reach grooves and crevices.

[0039] After completing step S3 and before proceeding to step S4, a dedicated sample recovery step is added. Specifically, after the rotating assembly 3 accurately transfers the temperature-measuring sampling assembly 4 and the cleaning assembly 38 directly above the sample pot 6, the control system first activates the cylinder 41, driving the push rod 42 downwards so that the sampling head 44 is precisely aligned with the receiving port of the sample pot 6. At this time, the molten steel sample collected in the sampling head 44 is completely released into the sample pot 6 through pneumatic drive or mechanical triggering. Specifically, after completing temperature-measuring sampling and raising the sampling head 44 and the temperature measuring head 45, the rotating assembly 3 immediately moves the device above the sample pot 6; the sample recovery step is performed first, draining the molten steel sample in the sampling head 44 into the sample pot 6; then the cleaning step is performed to thoroughly clean the used sampling head 44 and the temperature measuring head 45; after cleaning, the rotating assembly 3 rotates the device back above the refining pot 5 to stand by. This avoids contamination of new molten steel samples by debris generated during the cleaning process, and is particularly suitable for applications requiring high sample purity.
