Description

Technical Field

[0001] The present application relates to the technical field of steel metallurgy, and in particular to a sample breaking device capable of breaking molten steel samples during the steel smelting process. Background Art

[0002] The main purpose of sampling molten steel in steel smelting is to conduct chemical composition analysis and metallographic structure observation to ensure the quality of steel products and meet specific technical requirements.

[0003] Chemical analysis of crushed steel samples can determine the content of various elements in the steel, such as carbon, sulfur, phosphorus, and manganese. The content of these elements is crucial in determining the steel's physical and chemical properties, such as hardness, strength, and corrosion resistance. Microscopic observation of the microstructure of the crushed steel sample allows for assessment of grain size, phase distribution, and morphology—information crucial for evaluating the steel's mechanical properties. Therefore, sample analysis of crushed steel samples is a crucial step in quality control during steel production. Timely sampling and analysis can identify potential problems during production and enable adjustments to ensure that the final product meets quality requirements.

[0004] The traditional steel and metallurgical industry uses manual operation to break molten steel samples. Operators wear protective equipment such as heat-resistant gloves and protective glasses, use special sampling tools to remove the molten steel from the sampling position, and quickly place it in a pre-prepared sample container. The sample is then sent to the laboratory for subsequent processing and analysis. The state of the molten steel sample is a reddish ultra-high temperature solid (around 1000°C). There are major safety hazards in the manual operation process, which has an impact on the safety and health of personnel. In addition, the length of manual breaking time is uncontrollable, which can easily lead to delays in sample inspection and analysis results, and has a great impact on the control of existing casting components. Moreover, with the development of industrial automation, this breaking method has low efficiency, low precision and high labor costs. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the existing technology. Utility Model Content

Changes to these relative positional relationships are considered within the scope of this application without departing from the technical concepts disclosed herein.

[0031] In order to solve the problems existing in the prior art, the present application provides a molten steel sample breaking device, which can automatically break samples during the production process, effectively solving the existing problem of manual sample breaking of molten steel samples after sampling is completed, and isolating the safety risk of ultra-high temperature burns of about 1000°C in the molten steel sample during manual sample breaking. In addition, the use of this application can standardize the operating process. Compared with the uncontrollability of manual operation, this application can solidify the operating process, ensure the continuity of the operation, effectively shorten the sample breaking operation time, and improve the sample breaking efficiency. Applying this application in production practice can realize unmanned operation, promote safe production, and achieve reduction in staff and increase in efficiency. The structure and use process of the molten steel sample breaking device are described in detail below.

[0032] This application provides a molten steel sample breaking device, see Figure 1, mainly includes a molten steel sample crushing part 3 and a hammer crushing mechanism. Among them: the molten steel sample crushing part 3 mainly includes a sample crushing chamber 31 for accommodating the mud ball of the sampler 2, and a sample outlet is formed at the bottom of the sample crushing chamber 31. An opening and closing mechanism for opening or closing the sample outlet is installed at the sample outlet. When the hammer crushing mechanism crushes the molten steel sample and the mud ball captured by the mud ball of the sampler 2, the sample outlet can be opened to discharge the material. The hammer crushing mechanism includes a first hammer crushing mechanism 1 and a second hammer crushing mechanism 5. The two hammer crushing mechanisms are correspondingly installed on both sides of the sample crushing chamber 31. The two hammer crushing mechanisms are used to knock and break the mud ball of the sampler 2, so that the upper shell and the lower shell of the molten steel sample are both slid and separated from the molten steel sample, and the mud ball is broken and separated from the paper tube of the sampler 2. After removing the paper tube of the sampler 2, the sample and crushed mud ball particles can be obtained in the sample crushing chamber 31.

[0033] Compared with traditional manual sample breaking operations, the molten steel sample breaking device provided in this application realizes automated sample breaking through a hammer breaking mechanism and a sample outlet that can be opened or closed. It has standardized operating procedures and highly efficient operating processes, reduces manual participation, and achieves reduction in staff, cost reduction, and efficiency improvement.

[0034] In one embodiment, the above-mentioned sample breaking bin 31 is a shell structure, preferably a rectangular or cube-shaped shell structure, which is easy to process and manufacture. A cavity is formed in the shell structure to accommodate the mud ball of the sampler 2. The structural dimensions of the cavity are adapted to the structural dimensions of the front end of the sampler 2 mud ball racket of the molten steel sample. A sampling port is formed above the cavity, and the mud ball of the sampler 2 is inserted into the cavity from the sampling port. During specific application installation, a loading robot can be equipped to automatically insert the mud ball of the sampler 2 into the molten steel for sampling and insert the mud ball of the sampler 2 into the sample breaking bin 31 after sampling, thereby realizing unmanned production. At the same time, a sealing door or other structure can also be provided at the sampling port to prevent leakage of the molten steel.

[0035] In one embodiment, the first hammer crushing mechanism 1 includes a first sample-breaking hammer head 14 and a first driver that drives the first sample-breaking hammer head 14, and the second hammer crushing mechanism 5 has a second sample-breaking hammer head 54 and a second driver that drives the second sample-breaking hammer head 54. The first sample-breaking hammer head 14 and the second sample-breaking hammer head 54 can be driven to hammer back and forth toward the mud ball in the sampler 2 in the cavity. In this embodiment, the first driver and the second driver can be any linear actuator, such as an electric linear actuator, which uses an electric motor as a driving source and converts the rotational motion generated by the rotating motor into linear motion. Common ones include screw drive and chain drive. Another example is a hydraulic linear actuator, which uses the liquid in the hydraulic system as a power source and controls the flow of the liquid by adjusting the hydraulic valve to push the piston to achieve linear motion. In this embodiment, the hammer head is automatically driven to reciprocate by the linear actuator, and the driving force is controllable. The movement speed, position and acceleration of the hammer head can be precisely controlled to achieve highly precise movement. In addition, linear actuators have a simple design and few parts, so they generally have high reliability and long life. Hydraulic and pneumatic actuators, in particular, are more durable in harsh environments and can operate at higher speeds and greater forces, thus reducing hammering time.

[0036] In another embodiment, see Figure 1 The first hammer crushing mechanism 1 includes a first sample-breaking hammer head 14 and a first driver driving the first sample-breaking hammer head 14. The second hammer crushing mechanism 5 includes a second sample-breaking hammer head 54 and a second driver driving the second sample-breaking hammer head 54. The first sample-breaking hammer head 14 and the second sample-breaking hammer head 54 can be driven to reciprocate and hammer the mud ball of the sampler 2 in the cavity. The first driver includes a first hammer propulsion cylinder 11 and a first air hammer assembly 13 connected to the power output end of the first hammer propulsion cylinder 11, and the first air hammer assembly 13 is connected to the first sample-breaking hammer head 14. The first hammer crushing mechanism 1 also includes a first linear motion assembly 12 for guiding the first sample-breaking hammer head 14. The first linear motion assembly 12 includes a first guide rail and a first slider adapted to be slidably mounted on the first guide rail. The first slider is connected to the first air hammer assembly 13. The length direction of the first guide rail is the same as the hammering direction of the first sample-breaking hammer head 14. Similarly, the second driver includes a second hammer propulsion cylinder 51 and a second air hammer assembly 53 connected to the power output of the second hammer propulsion cylinder 51. The second air hammer assembly 53 is connected to a second sample-breaking hammer head 54. The second hammer breaking mechanism 5 also includes a second linear motion assembly 52 for guiding the second sample-breaking hammer head 54. The second linear motion assembly 52 includes a second guide rail and a second slider slidably mounted on the second guide rail. The second slider is connected to the second air hammer assembly 53. The longitudinal direction of the second guide rail is aligned with the hammering direction of the second sample-breaking hammer head 54.

[0037] The first air hammer assembly 13 and the second air hammer assembly 53 can use compressed air or gas as a power source, and control the movement of the piston through a pneumatic valve, thereby achieving linear movement of the hammer head.

[0038] In one embodiment, see Figure 2 The above-mentioned sample breaking chamber 31 is a shell structure surrounded by a first side wall 311, a second side wall 312, a third side wall 313, a fourth side wall 314 and a bottom wall 315, wherein: the first side wall 311 and the second side wall 312 are adjacent to each other and form a right angle, the fourth side wall 314 is opposite to the lower half of the first side wall 311, and an opening for allowing the first sample breaking hammer 14 to enter and exit is formed above the fourth side wall 314; the third side wall 313 is opposite to the upper half of the second side wall 312, and an opening for allowing the second sample breaking hammer 54 to enter and exit is formed below the third side wall 313 and above the bottom wall 315, that is, the hammering point of the first sample breaking hammer 14 in this application is higher than the hammering point of the second sample breaking hammer 54.

[0039] The bottom wall 315 is installed at the sample outlet. In order to open or close the sample outlet, the present application opens a horizontal sliding socket on the first side wall 311 and sets a slide on the inner surface of the second side wall 312. The bottom wall 315 can be inserted into the sample breaking chamber 31 from the horizontal sliding socket, and one side of the bottom wall 315 is adapted to be slidably connected to the slide. A corresponding card slot is opened on the inner surface of the fourth side wall 314. One end of the bottom wall 315 is adapted to be plugged into the horizontal sliding socket, and the other end is adapted to be plugged into the card slot. In this way, the horizontal sliding and structural installation of the bottom wall 315 are realized.

[0040] The opening and closing mechanism for opening or closing the sample outlet in this application includes a drive cylinder 32 mounted on the outer surface of the first side wall 311. The power output end of the drive cylinder 32 is connected to the end of the bottom wall 315 that extends out of the horizontal sliding socket. Driven by the drive cylinder 32, the bottom wall 315 can slide back and forth relative to the horizontal sliding socket to open or close the sample outlet. Of course, the opening and closing mechanism can also use a motor and ball screw structure or other linear actuator, as long as it can achieve horizontal drive of the bottom plate.

[0041] In one embodiment, a sample falling guide cylinder 4 can be installed below the sample outlet of the sample crushing bin 31, and a sample vibration centrifugal sorting device can be installed below the sample falling guide cylinder 4. In this way, the sample and crushed mud ball particles in the sample crushing bin 31 can automatically fall into the sample vibration centrifugal sorting device below through the opening and closing mechanism to realize automatic sorting and processing, which is conducive to the realization of full-process automation of molten steel sampling and testing.

[0042] In actual production practice, after the steel sample is automatically taken out by the equipment receiving robot inserted into the molten steel, the molten steel sample breaking device provided in this application can be used to automatically break the sample, thereby realizing automated production. The process of automatically breaking the sample using the molten steel sample breaking device provided in this application is as follows:

[0043] After the sampler 2 completes sampling, the front end of the sampler 2 mud ball racket steel sample is placed into the sample breaking chamber 31, and the first hammer breaking mechanism 1 and the second hammer breaking mechanism 5 are started. The first hammer propulsion cylinder 11 and the second hammer propulsion cylinder 51 are driven forward to push the sample breaking hammer head connected to the high-frequency air hammer assembly to perform high-frequency (20-30 times / second) hammering, and the mud ball part of the sampler 2 is knocked and broken, and presents broken particles; under the high-frequency hammering process, the upper and lower shells of the molten steel sample slide and separate from the molten steel sample; after 5s of high-frequency hammering, The mud head is crushed and separated from the paper tube of the sampler 2, the first hammer propulsion cylinder 11 is reset, and the first hammer propulsion cylinder 11 is retracted, so that the first hammer crushing mechanism 1 is separated from the upper part of the sample; and the second air hammer assembly 53 is reset, and the high-frequency hammering is stopped, but the second hammer propulsion cylinder 51 is still kept in the forward state to press the lower part of the molten steel sample. At this time, after removing the paper tube of the sampler 2, the second hammer propulsion cylinder 51 is retracted, and the sample outlet of the sample crushing bin 31 is opened, so that the sample and the crushed mud head particles fall into the sample vibration centrifugal sorting device, and the sample crushing operation is completed.

[0044] In summary, the present application provides a molten steel sample crushing device, which uses a cylinder to drive a high-frequency air hammer to strike the steel sample mud head, effectively breaking the sample while ensuring the integrity of the sample, and uses an upper hammer and a lower hammer to crush the sample mud head part, and the sample shell is separated, thereby realizing automatic sample crushing. Therefore, the present application uses a single device to replace manual operation to realize automated sample crushing. The equipment has a standardized operating process and a highly efficient operating process, which effectively improves the production operation rhythm, promotes efficient and safe production, ensures personnel safety, and indirectly promotes cost reduction and efficiency improvement.
