Description

Technical Field

[0001] This utility model relates to the field of steel smelting equipment technology, and more specifically, to a storage device for a molten steel sampler. Background Technology

[0002] Samplers are widely used in various stages of the smelting process. They allow for the rapid extraction of shaped steel samples for compositional analysis by instruments such as spectrometers, thereby reducing waste and improving economic efficiency. Currently, samplers used in furnace pre-process, furnace post-process, and refining processes include refractory components, racket-shaped sample molds, and protective tubes. The refractory component is housed within the protective tube, and its interior contains a cavity adapted to the racket-shaped sample mold. The sample mold is placed within the cavity, and a sampling port is opened on the protective tube. A quartz tube is positioned at the sampling port, and a slag-breaking cap is installed at the end of the quartz tube. The steel sample extracted by this sampler is racket-shaped.

[0003] In modern metallurgical production, the requirements for quality control of molten steel are becoming increasingly stringent. Chemical composition analysis of molten steel is crucial for the quality control of metallurgical products. During the chemical composition analysis process, the proper use of the furnace-front molten steel sampler during sampling directly affects the accuracy of the analysis. The outer shell of the furnace-front molten steel sampler is made of paper, which is easily deformed and contaminated by pressure, affecting the sampling process and the accuracy of the test results.

[0004] There are two existing methods for storing molten steel samplers. The first is to store them in the original factory cardboard boxes, but this is inconvenient to handle and cannot guarantee that the samplers will not be contaminated on site, which may affect the chemical composition analysis results. The second method is to stack them on site, but this is easy to be squeezed, and similarly cannot guarantee that the samplers will not be contaminated, which may also affect the chemical composition analysis results.

Two relatively parallel upright plates, the bottoms of which are respectively vertically fixed to the upper surface of the base; A slot plate, detachably disposed between a pair of upright plates, wherein the slot plate has a plurality of slot holes for accommodating the holding end of a molten steel sampler, the width of the slot holes being greater than the diameter of the holding end of the molten steel sampler and smaller than the diameter of its end sampling box. A dust cover, which is hinged to the top edge of one of the uprights, is sized to completely cover all the slot plates.

[0006] As a preferred embodiment, the dust cover has a buckle on the side away from the hinge, and the corresponding upright plate has a mounting bracket that cooperates with the buckle.

[0007] As a preferred embodiment, the inner sidewalls of the uprights are provided with guide rails for supporting the slot plate, and the slot plate is retractably mounted between a pair of uprights via the guide rails.

[0008] As a preferred embodiment, the guide rail is provided with a plurality of positioning holes spaced apart, and the end of the slot plate is provided with an elastic positioning pin that cooperates with the positioning holes.

[0009] As a preferred embodiment, casters are installed at the four corners of the bottom of the base, and each caster is equipped with a brake pad.

[0010] As a preferred embodiment, the base adopts a hollow structure and is equipped with a counterweight inside.

[0011] As a preferred embodiment, the surfaces of the base, upright plate, and slot plate are all treated with a smooth finish.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This device effectively isolates on-site dust pollution through a dust cover, and with its smooth surface treatment and dedicated slot design, it completely avoids sampler deformation and contamination. Its adjustable slot plate structure and flexible movable base significantly improve space adaptability and retrieval efficiency, thereby ensuring the accuracy and reliability of steel chemical composition analysis, while greatly reducing operational intensity and optimizing workflow.

Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments.

[0015] A storage device for a molten steel sampler, comprising: Base 1 is made of welded profiles, and its bottom is a flat support plane to ensure that the storage device is stably placed on the working surface. Two relatively parallel upright plates 2 are fixed vertically to the upper surface of the base 1 at their bottoms. Slot plate 3, detachable, is located between a pair of upright plates 2. The slot plate 3 has multiple slot holes 31 for accommodating the holding end of the molten steel sampler. The width of the slot hole 31 is greater than the diameter of the holding end of the molten steel sampler and smaller than the diameter of its end sampling box. Dust cover 4 is hinged to the top edge of one of the uprights 2 and is sized to completely cover all the slot plates 3. In use, the molten steel sampler is inserted sequentially into the slot holes 31 of the slot plate 3. Due to the special size design of the slot holes 31, the molten steel sampler can be placed stably and will not easily slip off. Then, the dust cover 4 is rotated around the hinge to completely cover the slot plate 3, effectively preventing dust and impurities from falling into the slot holes and avoiding contamination of the molten steel sampler. When the molten steel sampler needs to be retrieved, simply open the dust cover 4 and remove it from the corresponding slot hole 31; the operation is very convenient. Moreover, this storage device has a simple overall structure and low manufacturing cost, yet it provides a good storage environment for the molten steel sampler, extending its service life. Compared with existing storage methods, it is easy to retrieve and less prone to compression, ensuring that the sampler is not contaminated on-site and avoiding any impact on the chemical composition analysis results.

[0016] As a preferred embodiment, the dust cover 4 is provided with a buckle 42 on the side away from the hinge, and the corresponding upright plate 2 is provided with a bracket 21 that cooperates with the buckle 42.

[0017] With the cooperation of the buckle 42 and the mounting base 21, the dust cover 4 can be more securely placed over the slot plate 3, preventing it from opening on its own due to external force or slight shaking of the device, thus further improving the dustproof effect. At the same time, when it is necessary to open the dust cover 4 to retrieve the molten steel sampler, simply press the buckle 42 gently to separate it from the mounting base 21, and the dust cover 4 can be easily rotated around the hinge; the operation is simple and effortless. This design ensures both the stability of the dust cover 4 during use and ease of use.

[0018] As a preferred embodiment, guide rails 22 for supporting slot plates 3 are provided on the inner sidewalls of the opposing upright plates 2, and the slot plates 3 are detachably mounted between a pair of upright plates 2 via the guide rails 22. The design of the guide rail 22 not only makes the installation and removal of the slot plate 3 extremely convenient, but also allows users to easily pull out the slot plate 3 as needed in daily use for quick access to or storage of the molten steel sampler. This pull-out structure greatly improves the flexibility and practicality of the storage device, enabling users to manage the molten steel sampler more efficiently and flexibly arrange the number of slot plates 3 according to actual needs. Furthermore, the material and manufacturing process of the guide rail 22 have been carefully selected and optimized to ensure sufficient strength and wear resistance, enabling it to stably support the slot plate 3 and the molten steel sampler on it for a long period.

[0019] As a preferred embodiment, the guide rail 22 is provided with a plurality of positioning holes 221 at intervals, and the end of the slot plate 3 is provided with an elastic positioning pin 32 that cooperates with the positioning holes 221.

[0020] When the slot plate 3 is pushed into the appropriate position, the elastic positioning pin 32 will accurately engage with the corresponding positioning hole 221, achieving precise positioning and stable fixation of the slot plate 3. This design prevents the slot plate 3 from shaking or shifting during use, ensuring the stability of the molten steel sampler during storage. Moreover, when it is necessary to adjust the position of the slot plate 3 or remove the slot plate 3, a slight pull will disengage the elastic positioning pin 32 from the positioning hole 221, making operation very convenient. In addition, the multiple positioning holes 221 provide users with more options for the position of the slot plate 3, allowing for flexible adjustment of the spacing of the slot plates 3 according to the actual situation such as the size and quantity of the molten steel sampler, further improving the applicability and convenience of the storage device.

[0021] As a preferred option, casters 5 are installed at the four corners of the bottom of the base 1, and each caster 5 is equipped with a brake pad.

[0022] The omnidirectional wheels allow the entire storage unit to be easily moved to the required location without the need for multiple people to move it, greatly saving manpower and time. The brake pads ensure that the unit can be quickly and stably secured after being moved to the designated location, preventing slippage due to accidental collisions or uneven ground, thus ensuring the safety and stability of the molten steel sampler storage.

[0023] As a preferred option, the base 1 adopts a hollow structure, and a counterweight 11 is installed inside it.

[0024] The hollow structure design not only reduces the overall weight of the storage device, facilitating movement and operation, but also effectively enhances the stability of the device by incorporating a counterweight 11 inside. The weight and position of the counterweight 11 can be adjusted according to actual needs to adapt to the storage requirements of the molten steel sampler, ensuring that the storage device remains stable under various conditions and avoiding the risk of tipping over due to an unstable center of gravity.

[0025] As a preferred option, the surfaces of the base 1, the upright plate 2, and the slot plate 3 are all treated with a smooth finish. The smooth surface treatment not only enhances the aesthetics of the entire storage unit, making it look cleaner and more professional, but also reduces the adhesion of dirt and impurities, facilitating daily cleaning and maintenance. This treatment method also effectively prevents damage to the molten steel sampler caused by friction with rough surfaces during storage, thereby extending the service life of the molten steel sampler.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art, and their specifications and models can be selected according to actual conditions.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical embodiments described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
