Description

Technical Field

[0001] This utility model belongs to the technical field of metal storage devices, and relates to a device for isolating and storing titanium alloy ingots. Background Technology

[0002] Titanium alloys possess advantages such as high specific strength, good high-temperature performance, and excellent corrosion resistance, making them widely used in aerospace, medical, and shipbuilding industries. Currently, the most widely used method for producing titanium alloy ingots in engineering applications both domestically and internationally is vacuum arc melting (VAM). Ingots produced using this method are all cylindrical and are generally classified as primary, secondary, and tertiary castings. Primary castings typically have a solidified crust on their surface, formed by impurities volatilized from the minerals during the melting process and the outer layer of the ingot itself. This crust is rough and easily contaminated by substances it comes into contact with. For example, if a primary ingot is placed on the ground (whether it's a concrete or earthen surface), it can cause cross-contamination between the surface material and the ingot surface. Furthermore, for different grades of titanium alloys, the chemical composition of the outer crust on the ingot surface varies, posing a risk of cross-contamination upon contact. These situations can range from minor unevenness in the chemical composition of the ingot to serious metallurgical defects, ultimately rendering the ingot unusable. Therefore, how to effectively place ingots and avoid cross-contamination is a key focus within the industry.

[0003] In existing engineering techniques, the most common method to avoid cross-contamination between ingots and the ground is to lay steel plates or place angle steel on the ground. While this method effectively prevents ingots from contacting foreign objects on the ground, it cannot prevent the random rolling of ingots during storage or cross-contamination caused by contact between ingots. Furthermore, this method ignores the fact that steel plates and angle steel themselves are also foreign objects. Titanium alloy ingot production sites frequently use tap water for various cleanings, characterized by high temperature and high humidity. For materials like steel plates and angle steel, rusting is inevitable after a period of use. Rust itself easily adheres to the ingot surface, and in severe cases, it can lead to poor or even excessive levels of Fe and O chemical elements. Utility Model Content

[0004] The purpose of this invention is to provide a titanium alloy ingot isolation storage device, which solves the problems of existing ingot storage devices being unable to prevent ingots from rolling around during storage and cross-contamination caused by contact between ingots.

[0005] The technical solution adopted by this utility model is a titanium alloy ingot isolation storage device, including a storage rack body and at least two insertion rods. Both the storage rack body and the insertion rods are made of TC4 alloy. The storage rack body has multiple through holes that are inclined and arranged symmetrically on the left and right sides. The through holes are used to place the insertion rods.

[0006] The main body of the storage rack has a square slot for storing insertion rods.

[0007] The center lines of the through holes on the same side of the main body of the storage rack are parallel to each other.

[0008] The center line of the through hole on the left side of the storage rack body makes an angle of 135° with the horizontal plane, and the center line of the through hole on the right side makes an angle of 45° with the horizontal plane.

[0009] The main body of the storage rack is rectangular, and the through hole is located on the center line of the width of the main body of the storage rack.

[0010] Hooks are fixed to the left and right sides of the main body of the storage rack.

[0011] The insertion rod is a cylindrical rod, and the through hole is a circular through hole.

[0012] The surface roughness of the storage rack body and the insertion rod is ≥3.2μm.

[0013] The main body of the storage rack has 6 through holes, 3 on the left and 3 on the right. The diameter of the through holes is larger than the diameter of the insertion rod.

[0014] The beneficial effects of this utility model are as follows: (1) By opening multiple through holes at an angle on the main body of the storage rack and placing an insert rod in the through holes, the main body of the storage rack can bear the weight of the ingot, and the insert rod can limit the rolling range of the ingot, thus avoiding cross-contamination caused by ingots of different materials rolling randomly on the main body of the storage rack. (2) The multiple through holes on the main body of the storage rack are arranged symmetrically on the left and right. The position of the insertion rod can be adjusted according to the size of the ingot in actual application. For example, when the ingot diameter is large, the insertion rod can be placed in two through holes that are far apart. When the ingot diameter is small, the insertion rod can be placed in two through holes that are close together to limit the left and right rolling of the ingot. It is very practical. (3) A square insertion rod storage slot is opened on the main body of the storage rack to facilitate the storage of insertion rods and prevent operators from randomly piling up idle insertion rods; (4) Hooks are fixed on the left and right sides of the main body of the storage rack, which makes it easy to hang the ingot storage device on the hooks with slings or wire ropes and use a crane to lift the ingot storage device to the ingot storage area. It also makes it easy to use one or more of the titanium alloy ingot isolation storage devices in combination. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] Example 1 See Figure 1 and Figure 2 A titanium alloy ingot isolation storage device includes a storage rack body 1 and at least two insertion rods 2. The storage rack body 1 and the insertion rods 2 are both made of TC4 alloy, and their chemical composition meets the requirements of GB / T 3620.1-2016 Titanium and Titanium Alloy Grades and Chemical Composition, and their microstructure and properties meet the requirements of GB / T 2965-2023 Titanium and Titanium Alloy Rods.

[0019] The main body 1 of the storage rack has multiple through holes 3 at an angle. The multiple through holes 3 are arranged symmetrically from left to right. The through holes 3 are used to place the insertion rod 2. The center lines of the through holes 3 on the same side of the main body 1 of the storage rack are parallel to each other.

[0020] The main body 1 of the storage rack has a square insertion rod storage slot 4, which facilitates the storage of insertion rods and prevents operators from haphazardly piling up idle insertion rods, causing the surface of the insertion rods to be contaminated by other debris, which could then contaminate the titanium alloy ingot. It also prevents the random stacking of insertion rods from affecting the normal work of surrounding operators.

[0021] Titanium alloy ingot storage is a key buffer link connecting the casting process with subsequent processing (such as forging and rolling). Titanium alloy ingot storage devices are important infrastructure to ensure the stability of titanium alloy product quality, production cost, production safety and efficiency.

[0022] Existing methods for storing titanium alloy ingots typically involve laying steel plates or angle irons on the ground and then placing the ingots on top. While this method prevents the ingots from contacting external objects, it cannot prevent round or rod-shaped ingots from rolling around during storage, or from cross-contamination caused by contact between ingots. Furthermore, steel plates and angle irons are prone to rusting, and when they come into contact with the titanium alloy ingots, the rust adheres and affects subsequent processing. Therefore, this invention utilizes a storage rack body 1 made of TC4 alloy and multiple insertion rods 2 to form an isolated storage device for titanium alloy ingots. The storage rack body has multiple through holes at an angle for placing the insertion rods. During use, the insertion rods are placed in the appropriate through holes according to the size of the titanium alloy ingot to be stored. This prevents the titanium alloy ingots from being contaminated by rust and also prevents them from rolling around on the storage device, thus improving the safety and quality stability of the stored titanium alloy ingots.

[0023] Example 2 A titanium alloy ingot isolation storage device includes a storage rack body 1 and at least two insertion rods 2. The storage rack body 1 and the insertion rods 2 are both made of TC4 alloy. The storage rack body 1 has four through holes 3 at an angle. The four through holes 3 are arranged symmetrically on the left and right, that is, two on the left and two on the right. The through holes 3 are used to place the insertion rods 2.

[0024] The main body 1 of the storage rack has a square insertion rod storage slot 4 for storing unused insertion rods.

[0025] The center lines of the through holes 3 on the same side of the main body 1 of the storage rack are parallel to each other.

[0026] The centerline of the left through-hole 3 of the main body 1 of the storage rack forms a 135° angle with the horizontal plane, and the centerline of the right through-hole 3 forms a 45° angle with the horizontal plane. This makes the insert rods inserted into the through-holes on both sides form a V-shaped fixing frame. The V-shaped structure itself is a stable triangle, which distributes the force evenly and can better transfer the load to the entire frame, resulting in better structural rigidity. In addition, the V-shaped fixing frame can fix a wide range of ingot sizes, with small ingots located at the bottom and large ingots at the top, making it more widely applicable and ensuring high safety.

[0027] This invention features multiple through holes angled open on the main body of the storage rack, into which insert rods are placed. The main body of the storage rack can support the weight of the ingot, while the insert rods restrict the rolling range of the ingot, preventing cross-contamination caused by ingots of different materials rolling freely on the main body of the storage rack. The multiple through holes on the main body of the storage rack are arranged symmetrically from left to right, and the position of the insert rods can be adjusted according to the size of the ingot in actual application. For example, when the ingot diameter is large, insert rods can be placed in two through holes that are far apart, and when the ingot diameter is small, insert rods can be placed in two through holes that are close together, thus restricting the left and right rolling of the ingot, making it highly practical.

[0028] Example 3 A titanium alloy ingot isolation storage device includes a storage rack body 1 and at least two insertion rods 2. The storage rack body 1 and the insertion rods 2 are both made of TC4 alloy. The storage rack body 1 has multiple through holes 3 that are obliquely opened on it. The multiple through holes 3 are arranged symmetrically on the left and right sides, and the insertion rods 2 are placed in the through holes 3.

[0029] The main body 1 of the storage rack has a square insertion rod storage slot 4.

[0030] The center lines of the through holes 3 on the same side of the main body 1 of the storage rack are parallel to each other.

[0031] The center line of the left through hole 3 of the main body 1 of the storage rack makes an angle of 135° with the horizontal plane, and the center line of the right through hole 3 makes an angle of 45° with the horizontal plane.

[0032] The main body 1 of the storage rack is rectangular, and the through hole 3 is located on the center line of the width of the main body 1 of the storage rack.

[0033] This invention features multiple through holes angled open on the main body of the storage rack, into which insert rods are placed. The main body of the storage rack can support the weight of the ingot, while the insert rods restrict the rolling range of the ingot, preventing cross-contamination caused by ingots of different materials rolling freely on the main body of the storage rack. The multiple through holes on the main body of the storage rack are arranged symmetrically from left to right, and the position of the insert rods can be adjusted according to the size of the ingot in actual application. For example, when the ingot diameter is large, insert rods can be placed in two through holes that are far apart, and when the ingot diameter is small, insert rods can be placed in two through holes that are close together, thus restricting the left and right rolling of the ingot, making it highly practical.

[0034] Example 4 A titanium alloy ingot isolation storage device includes a storage rack body 1 and at least two insertion rods 2. The storage rack body 1 and the insertion rods 2 are both made of TC4 alloy. The storage rack body 1 has multiple through holes 3 that are obliquely opened on it. The multiple through holes 3 are arranged symmetrically on the left and right sides. The through holes 3 are used to place the insertion rods 2.

[0035] The main body 1 of the storage rack has a square insertion rod storage slot 4, which facilitates the storage of insertion rods and prevents operators from haphazardly piling up idle insertion rods. The center lines of the through holes 3 on the same side of the main body 1 of the storage rack are parallel to each other.

[0036] The center line of the left through hole 3 of the main body 1 of the storage rack makes an angle of 135° with the horizontal plane, and the center line of the right through hole 3 makes an angle of 45° with the horizontal plane, so that the insert rod inserted into the through holes on both sides forms a V-shaped fixing frame. The V-shaped structure itself is a stable triangle, and the force is evenly distributed, which can better transfer the load to the whole frame and make the structure more rigid.

[0037] The main body 1 of the storage rack is rectangular, and the through hole 3 is located on the center line of the width of the main body 1 of the storage rack.

[0038] The main body 1 of the storage rack is fixed with hooks 5 on the left and right sides, which makes it easy to hang the ingot storage device with slings or wire ropes and use an overhead crane to lift the ingot storage device to the ingot storage area. It also makes it easy to use one or more of the titanium alloy ingot isolation storage devices in combination.

[0039] Insertion rod 2 is a cylindrical rod, and through hole 3 is a circular through hole.

[0040] This invention features multiple through holes angled open on the main body of the storage rack, into which insert rods are placed. The main body of the storage rack can bear the weight of the ingot, while the insert rods can limit the rolling range of the ingot, thus preventing cross-contamination caused by ingots of different materials rolling freely on the main body of the storage rack. The multiple through holes on the main body of the storage rack are arranged symmetrically from left to right, and the position of the insert rods can be adjusted according to the size of the ingot in actual application. For example, when the ingot diameter is large, the insert rods can be placed in two through holes that are far apart, and when the ingot diameter is small, the insert rods can be placed in two through holes that are close together, thus limiting the left and right rolling of the ingot. It can be applied to various working conditions.

[0041] Example 5 A titanium alloy ingot storage device includes a storage rack body 1 and at least two insertion rods 2. The storage rack body 1 and the insertion rods 2 are both made of TC4 alloy. The storage rack body 1 has multiple through holes 3 that are obliquely opened on it. The multiple through holes 3 are arranged symmetrically on the left and right sides. The through holes 3 are used to place the insertion rods 2.

[0042] The main body 1 of the storage rack has a square insertion rod storage slot 4, which facilitates the storage of insertion rods and prevents operators from haphazardly piling up unused insertion rods.

[0043] The center lines of the through holes 3 on the same side of the main body 1 of the storage rack are parallel to each other.

[0044] The center line of the left through hole 3 of the main body 1 of the storage rack makes an angle of 135° with the horizontal plane, and the center line of the right through hole 3 makes an angle of 45° with the horizontal plane. This makes the insert rod inserted into the through holes on both sides form a V-shaped fixing frame. The V-shaped structure itself is a stable triangle, which distributes the force evenly and can better transfer the load to the whole frame, resulting in better structural rigidity.

[0045] The main body 1 of the storage rack is rectangular, and the through hole 3 is located on the center line of the width of the main body 1 of the storage rack.

[0046] Hooks 5 are fixed on the left and right sides of the main body 1 of the storage rack.

[0047] Insertion rod 2 is a cylindrical rod, and through hole 3 is a circular through hole.

[0048] The surface roughness of the storage rack body 1 and the insertion rod 2 is ≥3.2μm.

[0049] Example 6 A titanium alloy ingot isolation storage device includes a storage rack body 1 and at least two insertion rods 2. Both the storage rack body 1 and the insertion rods 2 are made of TC4 alloy. The length × width × height of the storage rack body 1 is 1320mm × 150mm × 100mm, and the surface roughness is ≥3.2μm. The dimensions of the insertion rods 2 are φ20mm × 600mm, and the surface roughness is ≥3.2μm. The main body of the storage rack is made of TC4 alloy, which can prevent rust and other contaminants from coming into contact with the titanium alloy ingots (conventional steel storage racks will rust and contaminate the ingots over time due to temperature and humidity changes). The insertion rod is also made of TC4 alloy, making it simple and convenient to operate. It can meet the storage needs of ingots of different sizes, ensuring 100% storage gaps and completely eliminating the risk of cross-contamination introduced by contact between ingots.

[0050] The storage rack body 1 has six through holes 3 at an angle, which are used to place the insertion rods 2. The center lines of the through holes 3 on the same side of the storage rack body 1 are parallel to each other. The position of the insertion rods limits the area of ​​ingot movement, which can effectively prevent the ingot from rolling randomly and reduce the safety risks caused by ingot rolling.

[0051] The six through holes are arranged symmetrically from left to right. The three through holes on the left are AA1, BB1, and CC1 from left to right, and the three through holes on the right are DD1, EE1, and FF1 from left to right. The center lines of DD1, EE1, and FF1 are at an angle of 45° to the horizontal plane, while the center lines of AA1, BB1, and CC1 are at an angle of 135° to the horizontal plane.

[0052] All six through holes are circular with an inner diameter of 25mm. Insertion rod 2 is a cylindrical rod with a diameter of 20mm, which facilitates easy insertion into the through holes during application.

[0053] The storage rack body 1 has a square insertion rod storage slot 4, which is 20mm away from the outer wall of the storage rack body 1; this facilitates the storage of insertion rods and prevents operators from haphazardly piling up unused insertion rods. The main body 1 of the storage rack is rectangular, and the through hole 3 is located on the center line of the width of the main body 1 of the storage rack, so that when titanium alloy ingots are placed, the main body of the storage rack is subjected to uniform force and the structure is stable.

[0054] The main body 1 of the storage rack is fixed with hooks 5 on the left and right sides, which makes it easy to hang the ingot storage device with slings or wire ropes and use an overhead crane to lift the ingot storage device to the ingot storage area. It also makes it easy to use one or more of the titanium alloy ingot isolation storage devices in combination.

[0055] When the size of the ingot to be stored is larger than the length of a single storage rack, multiple titanium alloy ingot isolation storage devices are hoisted together by an overhead crane and arranged in a single arrangement. Then, according to the size of the ingot, insertion rods are placed in the through holes on the main body of the storage rack at both ends, and the ingot is placed between two insertion rods to fix the large titanium alloy ingot.

[0056] This invention utilizes multiple through holes angled on the main body of the storage rack, into which insert rods are placed. The main body of the storage rack can bear the weight of the ingot, while the insert rods restrict the rolling range of the ingot, preventing cross-contamination caused by ingots of different materials rolling freely on the storage rack. This completely eliminates metallurgical defects caused by cross-contamination and avoids safety hazards caused by ingot rolling, ensuring the personal safety of operators. The multiple through holes on the main body of the storage rack are arranged symmetrically from left to right, allowing the position of the insert rods to be adjusted according to the size of the ingot in actual application. For example, when the ingot diameter is large, insert rods can be placed in two through holes that are far apart, while when the ingot diameter is small, insert rods can be placed in two through holes that are close together to restrict the left and right rolling of the ingot. The actual operation is simple, and one ingot storage device can realize the overall storage of ingots within the φ925mm specification range.

[0057] When using the titanium alloy ingot isolation and storage device of this utility model, follow these steps: Step 1: Attach slings or wire ropes to the hooks on both sides of the main body of the storage rack, and use an overhead crane to lift the main body of the ingot storage rack to the ingot storage area. One or more racks can be used in combination. Step 2: Insert the two insertion rods into holes AA1 and FF1, or holes BB1 and EE1, or holes CC1 and DD1 respectively. In this embodiment, holes AA1 and FF1 are suitable for storing ingots with a diameter D ranging from φ755 to φ925; holes BB1 and EE1 are suitable for storing ingots with a diameter D ranging from φ515 to φ755; and holes CC1 and DD1 are suitable for storing ingots with a diameter D ranging from φ225 to φ515. If the actual ingot length is less than or equal to 450mm, one ingot storage device is sufficient; simply place the ingot at its center position on the storage device. If the actual ingot length is greater than 450mm, two or three ingot storage racks are sufficient; during placement, the ingot axis must be perpendicular or approximately perpendicular to the length direction of the two ingot storage racks. Step 3: Place the ingot on the main body of the storage rack so that the ingot is positioned between the two insertion rods. Step 4: After use, remove the insertion stick and place it in the insertion stick storage slot for future use.
