Description

Technical Field

[0001] The invention belongs to the technical field of molten steel detection in a ladle refining furnace, and in particular is a temperature measurement sampling and slag sticking device for an LF furnace and an operation method thereof. Background Art

[0002] LF furnace, also known as ladle refining furnace, is the main off-furnace refining equipment in steel production. The steelmaking and ironmaking process is the process of chemical reaction between molten iron and molten steel at different temperatures through the LF furnace; temperature is the condition of chemical reaction, and composition is the result to be achieved by the chemical reaction; therefore, temperature measurement, sampling, oxygen determination, slag sticking, etc. in the steelmaking process are essential links in the ironmaking and steelmaking process. The data detected in these links are used to adjust the subsequent refining process of the LF furnace to remove harmful elements in the steel, protect the molten steel from excessive oxidation, absorb harmful gases, keep warm, reduce the burning loss of beneficial elements, absorb floating inclusions and reaction products, and ensure smooth carbon-oxygen reaction, thereby ensuring the quality of the molten steel.

[0003] In the related technology, there are currently some robotic automatic temperature measurement and sampling equipment that can realize automatic temperature measurement and sampling operations of molten steel. A temperature measuring gun or a sampling gun is separately configured through a lifting mechanism, and the corresponding probe is installed and inserted into the ladle to perform temperature measurement or sampling operations on the molten steel. It is impossible to perform temperature measurement and sampling operations on the molten steel at the same time, and it is impossible to perform slag sticking operations on the molten steel. Other equipment needs to be configured to remove slag from the molten steel, which increases the detection cost and low work efficiency.

[0004] Therefore, there is an urgent need for a temperature measurement, sampling and slag sticking device for LF furnace and an operation method thereof to solve the above technical problems. Summary of the invention

[0005] The object of the present invention is to provide a temperature measurement sampling and slag sticking device for LF furnace and an operation method thereof, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0006] Specifically, the first aspect of the present invention discloses a temperature measurement sampling and slag sticking device for an LF furnace, which is arranged on the top of the LF furnace and includes: A gun changing mechanism, a gun measuring mechanism and a lifting mechanism; the gun measuring mechanism is arranged on the lifting mechanism; The gun measuring mechanism comprises a slag sticking gun, a temperature measuring gun and a sampling gun, the front end of the slag sticking gun is provided with a slag sticking rod, the front end of the temperature measuring gun is provided with a temperature measuring probe, and the front end of the sampling gun is provided with a sampling probe; Wherein, the slag sticking gun is movably arranged on the gun measuring mechanism, and a slag blocking plate is arranged on the outer periphery of the rod body of the upper section of the slag sticking rod; The gun changing mechanism can respectively disassemble and assemble the slag sticking rod, the temperature measuring probe and the sampling probe.

[0007] The temperature measurement sampling and slag sticking device for LF furnace according to the present invention has at least the following beneficial effects: Slag sticking operation has different requirements and technical difficulties from temperature measurement and sampling operation; slag sticking requires a specific slag sticking rod structure and operation method. The slag sticking process requires the slag sticking rod to swing or stir in the molten steel so that the molten steel adheres to the slag sticking rod faster and better, ensuring that the slag sample can be accurately obtained. However, during the stirring of the molten steel, the molten steel or slag will splash onto the rod clamping part, causing damage or corrosion to the rod clamping part. By providing a slag retaining plate on the outer periphery of the rod at the upper section of the slag sticking rod, the splashing of molten steel or slag can be effectively avoided, ensuring the performance and life of the rod clamping part; The LF furnace temperature measurement, sampling and slag sticking device can automatically measure the temperature, sample and stick slag to the molten steel in the LF furnace ladle separately or simultaneously. Compared with the traditional molten steel detection device, the present invention can not only measure the temperature and sample the molten steel, but also stick slag to the molten steel at the same time, without the need for multiple sets of equipment to operate, effectively improving the integration of the molten steel detection device, enhancing the automation level of steelmaking, reducing the operating steps and detection costs of molten steel detection, and improving the accuracy of molten steel temperature measurement, sampling and stick slag analysis; The temperature measurement sampling and slag sticking device for the LF furnace can automatically replace the disposable slag sticking rod, temperature measurement probe and sampling probe with new ones through the gun changing mechanism, effectively reducing the operating error and labor intensity of manual disassembly and assembly of the probe or slag sticking rod, improving the convenience and safety of operation, and reducing the time for disassembly and assembly of the probe or slag sticking rod, thereby greatly improving work efficiency.

[0008] As a further solution of the present invention: a probe storage box is provided on one side of the gun changing mechanism, and a slag sticking rod storage rack is provided on the other side of the gun changing mechanism.

[0009] Since a probe storage box is provided on one side of the gun changing mechanism and a slag sticking rod storage rack is provided on the other side of the gun changing mechanism, after the gun changing mechanism removes the temperature measuring probe, the sampling probe or the slag sticking rod and places them into the waste box, the gun changing mechanism will clamp the corresponding new probe in the probe storage box, or clamp the new slag sticking rod on the slag sticking rod storage rack for automatic installation, thereby realizing the rapid removal and replacement of the old temperature measuring probe, the sampling probe and the slag sticking rod, reducing the errors and operation time of manual disassembly and assembly, and improving the automation degree and detection efficiency of the entire molten steel detection process.

[0010] As a further solution of the present invention: a sticky residue identification box is also provided on one side of the gun changing mechanism.

[0011] Since a slag sticking identification box is also provided on one side of the gun changing mechanism, when the gun changing mechanism disassembles the slag sticking rod, the slag sticking rod is moved into the slag sticking identification box, and the slag sticking is photographed and identified, so that the slag making effect in the ladle can be quickly judged without sending it to the inspection department. The operator only needs to monitor and analyze the slag sticking data, and adjust the subsequent refining process of the LF furnace based on the data analysis of the slag sticking to the molten steel, thereby ensuring the quality of the molten steel and improving the convenience and flexibility of operation.

[0012] As a further solution of the present invention: a mounting seat is arranged at the bottom of the gun changing mechanism, a swing arm is arranged at the top of the mounting seat, and a disassembly assembly is arranged at the top of the swing arm.

[0013] Since a mounting seat is provided at the bottom of the gun-changing mechanism, a swing arm is hingedly provided at the top of the mounting seat, and a disassembly assembly is hingedly provided at the top of the swing arm, the gun-changing mechanism is fixedly integrated on the device through the mounting seat, and moves within a certain range through the swing arm hinged on the top of the mounting seat and the disassembly assembly hinged on the swing arm, so that the gun-changing mechanism can move flexibly when disassembling and assembling the slag sticking rod, the temperature measuring probe and the sampling probe respectively, and automatically adapts to different positions and angles according to the disassembly and assembly of different probes or slag sticking rods, and uses the disassembly assembly to pull out the used probe or slag sticking rod, and install the unused probe or slag sticking rod, which effectively improves the accuracy and reliability of the gun-changing mechanism to disassemble and assemble the probe or slag sticking rod; at the same time, the disassembly assembly has the gun tip detection function of the gun measuring mechanism, and detects whether the gun tip is deformed in advance before installing a new probe or slag sticking rod, so as to avoid inaccurate installation or failure of the probe or slag sticking rod, resulting in distortion or failure of temperature measurement, sampling and slag sticking, and ensure that the gun measuring mechanism can effectively perform temperature measurement, sampling and slag sticking operations on the molten steel.

[0014] As a further solution of the present invention: an air gripper is disposed at the free end of the disassembly assembly component, and a guide module and a clamping module are disposed on one side of the air gripper.

[0015] An air gripper is provided at the free end of the disassembly and assembly component, a guide module and a clamping module are provided on one side of the air gripper, and the guide module and the clamping module are driven by the air gripper. The guide module can accurately install the probe or the slag sticking rod on the corresponding measuring gun mechanism, thereby ensuring the correct installation position of the probe and the slag sticking rod; and the clamping module can grasp and clamp the disassembly and assembly process of the probe or the slag sticking rod, thereby ensuring the stability of the disassembly and installation process of the probe or the slag sticking rod; the whole process does not require manual intervention, and the old probe or the slag sticking rod can be replaced with a new one, thereby improving the working ability of the device to continuously detect the molten steel in the ladle and improving the working efficiency.

[0016] As a further solution of the present invention: a positioning plate is provided on the other side of the air gripper.

[0017] By providing a positioning plate on the other side of the air gripper, it is possible to determine whether the slag sticking gun, temperature measuring gun and sampling gun are within the guide range of the guide module, and to detect in advance whether the slag sticking gun, temperature measuring gun and sampling gun have the conditions for automatically installing the probe or slag sticking rod, thereby effectively avoiding automatic installation when the gun head is not correctly in place, reducing the risk of accidents caused by improper operation, and ensuring that the slag sticking gun, temperature measuring gun and sampling gun will automatically install the probe or slag sticking rod when the positioning plate detects that the installation conditions are met, thereby improving the safety of operation.

[0018] As a further solution of the present invention: a lifting motor is arranged on the top of the lifting mechanism, a support hinge is arranged on one side of the lifting mechanism, the gun measuring mechanism is hinged to the support hinge, and an electric cylinder is also arranged on one side of the lifting mechanism.

[0019] Since a lifting motor is provided on the top of the lifting mechanism, a supporting hinge is provided on one side of the lifting mechanism, and the measuring gun mechanism is hinged to the supporting hinge, the measuring gun mechanism is connected to the lifting mechanism in a hinged manner, which improves the installation convenience of the measuring gun mechanism, and an electric cylinder is also provided on one side of the lifting mechanism, and the angle of the lifting mechanism is adjusted by the electric cylinder, so that the slag gun, the temperature measuring gun and the sampling gun can be quickly aimed at the furnace mouth of the LF furnace, and the slag gun, the temperature measuring gun and the sampling gun are inserted into the molten steel in the ladle through the lifting motor, and the temperature, sampling or slag sticking operations are performed on the molten steel, so that the angle of the measuring gun mechanism can be adjusted according to the furnace mouth position of different LF furnaces, so that the slag gun, the temperature measuring gun and the sampling gun can be accurately inserted into the ladle, and the temperature, sampling or slag sticking of the molten steel are performed, thereby improving the versatility and operational flexibility of the device.

[0020] As a further solution of the present invention: a measuring channel is arranged on the top of the LF furnace, the top of the measuring channel is open, a furnace cover which opens and closes automatically is arranged on the top of the measuring channel, a feeding channel is arranged on one side of the measuring channel, and the feeding channel is connected with the measuring channel.

[0021] Since a measuring channel is provided on the top of the LF furnace, the top of the measuring channel is open, and an automatically opening and closing furnace cover is provided on the top of the measuring channel, and a feeding channel is provided on one side of the measuring channel, and the feeding channel is connected with the measuring channel, the furnace cover of the LF furnace can be adaptively opened or closed according to the detection requirements, so as to facilitate the slag sticking gun, temperature measuring gun and sampling gun to enter the ladle through the measuring channel, and measure the temperature, sample and stick slag to the molten steel; after the temperature measurement, sampling or slag sticking is completed, the slag sticking gun, temperature measuring gun and sampling gun rise to the top of the LF furnace, and the furnace cover is automatically closed at this time, which can effectively reduce the overflow of smoke and dust in the ladle and reduce the pollution to the production environment; at the same time, when the furnace cover is closed, the material transportation is not affected through the feeding channel, so as to avoid the inability to add materials to the molten steel during detection, thereby ensuring that both the detection requirements of the molten steel and the material transportation can be met, thereby improving the detection and production efficiency of the molten steel.

[0022] The second aspect of the present invention also discloses an operation method of a temperature measurement sampling and slag sticking device for a LF furnace, comprising the following steps: S1. Start the device, and the lifting mechanism drives the measuring gun mechanism to extend into the ladle of the LF furnace to measure the temperature of the molten steel, take samples, and fix slag; S2. The gun changing mechanism respectively disassembles and assembles the temperature measuring probe after temperature measurement, the sampling probe after sampling, and the slag sticking rod after slag sticking.

[0031] Slag sticking operation has different requirements and technical difficulties from temperature measurement and sampling operation; slag sticking requires a specific slag sticking rod structure and operation method. The slag sticking process requires the slag sticking rod to swing or stir in the molten steel so that the molten steel adheres to the slag sticking rod faster and better, ensuring that the slag sample can be accurately obtained. However, during the stirring of the molten steel, the molten steel or slag will splash onto the rod clamping part, causing damage or corrosion to the rod clamping part. By providing a slag retaining plate on the outer periphery of the rod at the upper section of the slag sticking rod, the splashing of molten steel or slag can be effectively avoided, ensuring the performance and life of the rod clamping part; Specifically, the molten steel in the ladle of the LF furnace 1 is detected in advance by a liquid level detection device to detect the height of the molten steel liquid level, and the molten steel liquid level height data is transmitted to the automatic control system of the device. After the prerequisites for temperature measurement, sampling and slag sticking are met, the automatic control system determines the stroke of the lifting mechanism 4 to drive the measuring gun mechanism 3 to descend, so that the slag sticking rod 311, the temperature measuring probe 321 and the sampling probe 331 are inserted into the molten steel to a depth of 300mm-500mm, thereby ensuring the effectiveness and accuracy of temperature measurement, sampling and slag sticking of the molten steel; The LF furnace temperature measurement, sampling and slag sticking device can automatically measure the temperature, sample and stick slag to the molten steel in the LF furnace ladle separately or simultaneously. Compared with the traditional molten steel detection device, the present invention can not only measure the temperature and sample the molten steel, but also stick slag to the molten steel at the same time, without the need for multiple sets of equipment to operate, effectively improving the integration of the molten steel detection device, enhancing the automation level of steelmaking, reducing the operating steps and detection costs of molten steel detection, and improving the accuracy of molten steel temperature measurement, sampling and stick slag analysis; The temperature measurement sampling and slag sticking device for the LF furnace can automatically replace the disposable slag sticking rod 311, the temperature measurement probe 321 and the sampling probe 331 with new ones through the gun changing mechanism 2, effectively reducing the operating errors and labor intensity of manual disassembly and assembly of the probe or the slag sticking rod, improving the convenience and safety of operation, and reducing the time for disassembly and assembly of the probe or the slag sticking rod, thereby greatly improving work efficiency.

The operator only needs to monitor and analyze the slag sticking data, and adjust the subsequent refining process of the LF furnace according to the data analysis of the slag sticking to the molten steel, so as to ensure the quality of the molten steel and improve the convenience and flexibility of operation.
