Description

Technical Field

[0001] This utility model relates to the field of metallurgical testing technology, and in particular to a gun body and a testing gun. Background Technology

[0002] Steelmaking and ironmaking are processes in which molten steel and molten iron react chemically at different temperatures. Temperature is the condition for the chemical reaction, and composition is the result that the chemical reaction aims to achieve. Therefore, detecting the temperature and composition of molten steel / molten iron is an essential part of the steelmaking and ironmaking process.

[0003] In existing technologies, the temperature and composition of molten steel / iron are typically detected using a testing lance. A testing lance usually consists of a lance body and a measuring element mounted at the end of the lance body. The measuring element can be further categorized into various types, giving the testing lance different functions. For example, testing lances can generally be divided into temperature-measuring lances and sampling lances. The main difference lies in the measuring element mounted on the front of the lance body. A sampling lance is a tool used in steelmaking / ironmaking that uses a sampler to take samples of molten steel / iron, while a temperature-measuring lance is a tool used in steelmaking / ironmaking that uses a temperature probe to measure the temperature of molten steel / iron. The sampler is a dedicated disposable consumable for taking samples of molten steel / iron during steelmaking / ironmaking, and the temperature probe is a dedicated disposable consumable for measuring the temperature of molten steel / iron during steelmaking / ironmaking. With technological advancements, automatic temperature measurement and sampling systems have emerged for automated temperature measurement and sampling. During the smelting process, a testing lance can be inserted into the high-temperature molten steel / iron using mechanical equipment for automatic sampling and temperature measurement.

[0004] The existing gun body mainly consists of a main barrel and a spare part. The spare part is connected to one end of the main barrel, while the measuring component is connected to the other end of the spare part. Because the measuring gun measures high-temperature molten steel / iron, its service life is generally short, and the front end of the gun body (the spare part end) is easily damaged, requiring frequent replacement of the spare part. However, during use, steel slag / iron slag easily adheres to the connection point between the spare part and the main barrel, causing the spare part to easily become one with the main barrel. This makes disassembly and replacement of the spare part difficult, and it prevents quick replacement of the spare part after the gun body is damaged. Utility Model Content

[0005] To address the problem of rapid replacement of front-end spare parts after damage to the gun body in existing technologies, this invention provides a gun body that adds an intermediate gun barrel between the main barrel and the spare parts. This intermediate gun barrel serves as a transition connecting the main barrel and the spare parts. When the spare parts are damaged, they can be removed from the intermediate gun barrel and replaced with new spare parts. Furthermore, the three-section structure allows for replacement of only one part depending on the extent of damage, reducing replacement costs.

[0006] A gun body for a testing gun, comprising a main barrel, gun parts, and an intermediate barrel; The gun spare parts are separated from the main gun barrel; The intermediate barrel is disposed between the main barrel and the gun spare part, and is detachably connected to both the main barrel and the gun spare part.

[0007] Preferably, a first temperature compensation wire is provided inside the main gun barrel; The gun spare part is equipped with a second temperature measurement compensation wire, which is connected to the first temperature measurement compensation wire. The intermediate gun barrel is located outside the cable connection point between the first temperature compensation wire and the second temperature compensation wire.

[0008] Preferably, it also includes a heat insulation sleeve, which is disposed outside the intermediate gun barrel.

[0009] Preferably, the second temperature measuring compensation wire is an armored compensation wire, and the heat insulation sleeve is a mica tube.

[0010] Preferably, a wiring window is provided on the side wall of the intermediate gun barrel, and the wiring window is located at the cable connection between the first temperature compensation wire and the second temperature compensation wire.

[0011] Preferably, a rotating shield is also provided outside the intermediate gun barrel. The rotating shield has a notch corresponding to the wiring window. The rotating shield is rotatably disposed outside the intermediate gun barrel to open and close the wiring window.

[0012] Preferably, the intermediate barrel is connected to the gun spare part by a movable lock nut, or the intermediate barrel is connected to the gun spare part by a thread; The intermediate barrel is connected to the main barrel by screws or bolts.

[0013] Preferably, a slag-blocking disc is provided on the outer side of the gun spare part; The gun spare parts include a high-temperature alloy barrel body and a connector disposed at one end of the barrel body, the connector being detachably connected to the intermediate barrel. The high-temperature alloy barrel body includes a first part and a second part arranged in sequence. The first part is located at one end near the connector, and the second part is used to install the measuring component. The first part is covered with a protective cover.

[0014] Preferably, the main barrel includes an inner barrel and an outer barrel, with the inner barrel and the outer barrel spaced apart to form a cooling medium accommodating space.

[0015] A testing gun includes a gun body as described in any one of the above-mentioned testing guns and a testing element, the testing element being mounted at one end of the gun body remote from the intermediate gun barrel.

[0016] Compared with the prior art, the present invention provides a gun body for a testing gun, which includes a main gun barrel, a spare part, and an intermediate gun barrel; the spare part is separated from the main gun barrel; the intermediate gun barrel is disposed between the main gun barrel and the spare part, and is detachably connected to both the main gun barrel and the spare part. The gun body of the testing gun adds an intermediate gun barrel section between the main gun barrel and the spare part, using the intermediate gun barrel as a transition connecting the main gun barrel and the spare part. This intermediate gun barrel separates the main gun barrel from the spare part, thereby preventing steel slag / iron slag from splashing onto the connection point between the main gun barrel and the spare part, causing the spare part to stick to the main gun barrel and making separation difficult. This also reduces the difficulty of replacing the spare part. When the spare part is damaged, it can be removed from the intermediate gun barrel and replaced with a new spare part. Furthermore, the intermediate barrel is detachably connected to the main barrel and the gun spare parts, and adopts a three-section structure, which can reduce replacement costs by replacing only one part according to the damage.

[0024] This utility model provides a gun body for a testing gun, comprising a main barrel, a spare part, and an intermediate barrel; the spare part is spaced apart from the main barrel; the intermediate barrel is disposed between the main barrel and the spare part, and is detachably connected to both the main barrel and the spare part. The gun body of the testing gun adds an intermediate barrel section between the main barrel and the spare part, serving as a transition between them and separating them. This prevents steel slag / iron slag from splashing onto the connection point and causing the spare part to stick to the main barrel, making separation difficult. This also reduces the difficulty of replacing the spare part. When the spare part is damaged, it can be removed from the intermediate barrel and replaced with a new spare part. Furthermore, the intermediate barrel is detachably connected to the main barrel and the gun spare parts, and adopts a three-section structure, which can reduce replacement costs by replacing only one part according to the damage.

[0025] Please refer to the following: Figures 1 to 5 In one embodiment, a gun body 100 for a measuring gun is provided, which is mainly used to solve the problem of difficulty in replacing the front-end spare parts after the existing measuring gun is damaged. In addition, in some preferred embodiments, it is also used to solve the problem of the influence of the external high temperature environment on the measurement accuracy of the compensation wire inside the measuring gun.

[0026] The gun body 100 of the measuring gun includes a main barrel 10, a spare part 20, and an intermediate barrel 30, with the spare part 20 spaced apart from the main barrel 10. The intermediate barrel 30 is disposed between the main barrel 10 and the spare part 20, and is detachably connected to both the main barrel 10 and the spare part 20.

[0027] In other words, in the gun body 100 of the test gun provided in this embodiment, an intermediate gun barrel 30 is added between the main gun barrel 10 and the gun spare part 20, and the intermediate gun barrel 30 serves as a transition for connecting the main gun barrel 10 and the gun spare part 20.

[0028] Understandably, because the measuring gun measures high-temperature molten steel / iron, its service life is generally short, and spare parts need frequent replacement. However, in existing measuring guns, the spare parts are directly connected to one end of the main barrel. During use, steel slag / iron slag easily adheres to the connection point between the spare parts and the main barrel, making it difficult to disassemble and replace the spare parts at the front of the gun body, hindering quick replacement; in some cases, the spare parts may even become impossible to remove, requiring the entire measuring gun to be replaced.

[0029] In this embodiment, the gun body 100 of the testing gun has an additional intermediate gun barrel 30 between the main gun barrel 10 and the gun spare part 20. The intermediate gun barrel 30 separates the main gun barrel 10 from the gun spare part 20, thus preventing steel slag / iron slag from splashing onto the connection between the main gun barrel 10 and the gun spare part 20 and causing them to stick together, making separation difficult. This reduces the difficulty of replacing the gun spare part 20. When the gun spare part 20 is damaged, it can be removed from the intermediate gun barrel 30 and replaced with a new one. Furthermore, the intermediate gun barrel 30 is detachably connected to both the main gun barrel 10 and the gun spare part 20, employing a three-section structure. Depending on the extent of damage, only one part needs to be replaced, reducing replacement costs. Even if the gun spare part 20 is stuck to the intermediate gun barrel 30 and cannot be disassembled, the intermediate gun barrel 30 can be removed from the main gun barrel 10 without replacing the main gun barrel 10.

[0030] Preferably, in one embodiment, a first temperature compensation wire 40 is disposed inside the main barrel 10, and a second temperature compensation wire 50 is disposed inside the gun spare part 20, the second temperature compensation wire 50 being connected to the first temperature compensation wire 40. The intermediate barrel 30 is disposed outside the cable connection point between the first temperature compensation wire 40 and the second temperature compensation wire 50. That is, in this embodiment, the intermediate barrel 30 serves as a transition point for the connection between the main barrel 10 and the gun spare part 20, and as a storage location for internal cable connection points. By placing the intermediate barrel 30 at the storage location for internal cable connection points, internal cable connections are facilitated.

[0031] It is understandable that, since the object measured by the probe body 100 is usually molten steel / iron at high temperatures, the working environment of the probe body 100 is usually a high-temperature environment. When the probe body 100 is used for temperature measurement, it is easily affected by the external high-temperature environment, leading to temperature measurement deviations.

[0032] Preferably, in one embodiment, the gun body 100 of the measuring gun further includes a heat insulation sleeve 60, which is disposed outside the intermediate gun barrel 30. The heat insulation sleeve 60 is mainly used to reduce the influence of the external high temperature environment on the compensation wires inside the gun, and to reduce the impact of the external high temperature environment on the measurement accuracy of the compensation wires inside the gun. By setting the heat insulation sleeve 60, the internal cables can be further isolated from the external high temperature environment, providing good heat insulation protection for the cable connection points of the first temperature compensation wire 40 and the second temperature compensation wire 50 inside the intermediate gun barrel 30.

[0033] More preferably, in one embodiment, the heat insulation sleeve 60 is made of mica tube, that is, the heat insulation sleeve 60 is made of mica material, which has good heat resistance and can provide perfect heat insulation protection for the cable connection of the first temperature compensation wire 40 and the second temperature compensation wire 50.

[0034] Specifically, in one embodiment, the heat insulation sleeve 60 can be connected to the intermediate gun barrel 30 and / or the gun spare part 20 to fix the position of the heat insulation sleeve 60. Furthermore, the heat insulation sleeve 60 can also be a detachable connection.

[0035] Preferably, in one embodiment, a wiring window 311 is provided on the side wall 31 of the intermediate barrel 30. The wiring window 311 is correspondingly located at the cable connection point of the first temperature compensation wire 40 and the second temperature compensation wire 50. The wiring window 311 facilitates the connection of the first temperature compensation wire 40 and the second temperature compensation wire 50 inside the gun body, further reducing the difficulty of cable connection and installation.

[0036] More preferably, in one embodiment, a rotating shield 70 is further provided outside the intermediate gun barrel 30. The rotating shield 70 has a notch 71 corresponding to the wiring window 311. The rotating shield 70 is rotatably disposed outside the intermediate gun barrel 30 to open and close the wiring window 311. That is, in this embodiment, by rotating the rotating shield 70, the position of the notch 71 and the wiring window 311 is changed, thereby realizing the opening and closing of the wiring window 311. For example, when it is necessary to connect and install the first temperature compensation wire 40 and the second temperature compensation wire 50, the rotating shield 70 can be rotated so that the notch 71 is facing the wiring window 311, thereby facilitating the operator to connect and install the cables. After the cable connection and installation are completed, the rotating shield 70 can be rotated again to offset the notch 71 from the wiring window 311, thereby providing heat insulation protection for the cable connection of the first temperature compensation wire 40 and the second temperature compensation wire 50 through the rotating shield 70.

[0037] Specifically, in one embodiment, the rotating shield 70 and the intermediate barrel 30 are fixed together by fasteners 80. Once the rotating shield 70 has rotated to its position, the fasteners 80 fix the relative position between the rotating shield 70 and the intermediate barrel 30, thereby preventing accidental rotation of the rotating shield 70. In one embodiment, the rotating shield 70 has at least two mounting positions in the circumferential direction (or the intermediate barrel 30 may have at least two mounting positions in the circumferential direction), facilitating the fixing of the rotating shield 70's position under different requirements. Specifically, in one embodiment, the fasteners 80 may be screws.

[0038] Preferably, in one embodiment, the second temperature-measuring compensation lead 50 is an armored compensation lead. Using an armored compensation lead extends the lead's service life, reduces measurement errors, and improves the accuracy and reliability of temperature measurement.

[0039] Understandably, in existing technologies, most gun spare parts and main gun barrels are connected by screws or bolts, making replacement difficult and failing to meet the fast-paced requirements of on-site steelmaking production. Preferably, in one embodiment, the intermediate gun barrel 30 and the gun spare part 20 are connected by a movable locking nut 90, thereby enabling quick connection between the intermediate gun barrel 30 and the gun spare part 20 and improving the replacement efficiency of the gun spare part 20.

[0040] Specifically, in one embodiment, the intermediate barrel 30 is connected to the main barrel 10 by screws or bolts.

[0041] More specifically, in one embodiment, one end of the intermediate gun barrel 30 is provided with the movable locking nut 90, and the other end of the intermediate gun barrel 30 is provided with a mounting flange 32, which is connected to the main gun barrel 10 by screws or bolts.

[0042] Please refer to the following: Figure 6 In other embodiments, the detachable connection between the intermediate barrel 30 and the gun spare part 20 can also be that the intermediate barrel 30 and the gun spare part 20 are connected by threads. For example, one end of the gun spare part 20 is provided with an external thread 201, and one end of the intermediate barrel 30 is provided with an internal thread 301 that matches the external thread 201.

[0043] Please continue reading. Figure 4Preferably, in one embodiment, a slag-blocking disc 21 is provided on the outer side of the gun spare part 20. The slag-blocking disc 21 is mainly used to block the impact of steel slag splashing during the measurement process. The gun spare part 20 includes a gun barrel body 22 and a connector 23 disposed at one end of the gun barrel body 22. The connector 23 is detachably connected to the intermediate gun barrel 30. The gun barrel body 22 includes a first part and a second part 222 disposed sequentially. The first part is located at the end near the connector 23, while the second part 222 is the part of the gun barrel body 22 used to install the measuring device. A protective sleeve 24 is provided on the outside of the first part. That is, the part of the gun barrel body 22 without the measuring device is protected by the protective sleeve 24, thereby preventing slag from sticking to the gun barrel body 22.

[0044] Specifically, in one embodiment, the connector 23 is an external thread connector, and the connector 23 is connected to the movable lock nut 90.

[0045] Specifically, in one embodiment, the slag-blocking disc 21 is disposed on the protective sleeve 24 at one end near the connector 23.

[0046] It is understandable that existing gun spare parts are typically made of ordinary carbon steel, which lacks sufficient strength, is prone to bending, and makes it difficult to achieve fully automated assembly and disassembly of the test pieces. Preferably, in one embodiment, the barrel body 22 is a high-temperature alloy barrel body, that is, the barrel body 22 is made of a high-temperature alloy material, thereby ensuring that the barrel body 22 has sufficient strength and high-temperature resistance during temperature measurement / sampling, and better realizing fully automated assembly and disassembly of the test pieces.

[0047] Please refer to the following: Figure 5 Preferably, in one embodiment, the main barrel 10 has a double-layer barrel structure, comprising an inner barrel 11 and an outer barrel 12. The inner barrel 11 and the outer barrel 12 are spaced apart to form a cooling medium receiving space 13. This structure reduces the impact of the external high-temperature environment on the main barrel 10, greatly improving its heat insulation and heat dissipation effects. For example, during use, compressed air / nitrogen can be introduced into the cooling medium receiving space 13 for cooling, thereby reducing the impact of the external high-temperature environment on the temperature compensation wire inside the gun body.

[0048] Specifically, in one embodiment, the main gun barrel 10 is a double-layer steel pipe structure.

[0049] Please continue reading. Figure 1In one embodiment, a testing gun 1000 is also provided, comprising a gun body 100 and a measuring element 200, wherein the measuring element 200 is mounted at the end of the gun assembly 20 away from the intermediate gun barrel 30. The measuring element 200 can be any functional component required in the smelting process. For example, the measuring element 200 can be a temperature probe, thus the testing gun 1000 is a temperature gun; the measuring element 200 can also be a sampler, thus the testing gun 1000 is a sampling gun.

[0050] When the measuring element 200 is a temperature probe, the temperature compensation wire inside the gun body 100 of the measuring gun can be connected to the measuring element 200 and the temperature measuring instrument respectively.

[0051] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
