Description

Technical Field

[0001] This utility model relates to the field of converter steelmaking technology, and more specifically, to a slag-blocking structure for tapping steel in converter steelmaking. Background Technology

[0002] Converter steelmaking is an important steelmaking process that uses molten iron, scrap steel, and ferroalloys as main raw materials. Steel is produced through oxidation and reduction reactions within the converter. Converter steelmaking does not require external energy; it primarily relies on the physical heat of the molten iron itself and the chemical reactions between its components to generate heat. In the metallurgical industry, slag blocking during steel tapping is a critical step. Existing slag blocking structures for converter steelmaking typically use welding or several bolts to fix the slag plugs, making quick disassembly and assembly difficult. This hinders replacement and reduces the ease of maintenance. Therefore, this invention designs a new slag blocking structure for converter steelmaking to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a slag-blocking structure for tapping steel in a converter to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A slag-blocking structure for converter steelmaking includes a frame, a slag-blocking plug, an assembly, and two limiting blocks. A telescopic cylinder is fixedly mounted on the upper end of the frame. A guide rail is fixedly mounted on the telescopic end of the telescopic cylinder. A transmission seat is slidably connected to the bottom side of the guide rail. A drive assembly for driving the transmission seat to move horizontally is provided on the guide rail. The assembly is fixedly connected to one end of the transmission seat. A platform is fixedly mounted on the assembly via a column. An electric push rod is fixedly mounted on the upper end of the platform. A lifting seat is fixedly mounted on the telescopic end of the electric push rod. The two limiting blocks slide through both sides of the assembly. A connecting rod is movably hinged between the electric push rod and the limiting blocks. A positioning protrusion is provided on the slag-blocking plug. The assembly is slidably sleeved on the outside of the positioning protrusion. A side groove adapted to the limiting block is opened on the side of the positioning protrusion.

[0006] As a preferred embodiment of this utility model, the drive assembly includes a motor and a lead screw shaft. The motor is fixedly installed at one end of the guide rail, the lead screw shaft is fixedly connected to the drive end of the motor, and the transmission seat is threaded onto the outside of the lead screw shaft.

[0007] As a preferred embodiment of this utility model, a control panel is fixedly installed on the outer side of the frame, and the output end of the control panel is electrically connected to the input end of the telescopic cylinder, the motor and the electric push rod.

[0008] As a preferred embodiment of this utility model, two guide pillars are symmetrically fixedly installed inside the frame, and the guide rail is slidably sleeved on the outside of the guide pillars.

[0009] As a preferred embodiment of this utility model, the number of columns is four, and the lifting seat is slidably sleeved on the outside of the columns.

[0010] As a preferred embodiment of this utility model, each corner of the bottom of the frame is provided with a movable wheel, and a brake valve is provided on the movable wheel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a drive assembly and a telescopic cylinder to move the slag-blocking plug horizontally and vertically, respectively. The position of the slag-blocking plug can be adjusted according to actual conditions for slag blocking. When the slag-blocking plug needs replacement, an electric push rod drives the lifting seat to descend, and a connecting rod drives the limiting block to slide outwards along the side of the fitting until the limiting block disengages from the side groove of the positioning protrusion, allowing the slag-blocking plug to be removed and replaced. When installing the replaced slag-blocking plug, the fitting is placed over the positioning protrusion of the slag-blocking plug, and an electric push rod drives the lifting seat to rise, and a connecting rod drives the limiting block to slide inwards along the side of the fitting until the limiting block engages with the side groove of the positioning protrusion, completing the installation of the slag-blocking plug for use. This facilitates quick installation and removal of the slag-blocking plug, making replacement more convenient and improving the ease of maintenance of the slag-blocking structure.

[0019] like Figures 1 to 4 As shown, this utility model provides a slag-blocking structure for converter steelmaking, including a frame 1, a slag-blocking plug 2, a mounting assembly 4, and two limiting blocks 7. A telescopic cylinder 101 is fixedly installed on the upper end of the frame 1, and a guide rail 3 is fixedly installed on the telescopic end of the telescopic cylinder 101. A transmission seat 6 is slidably connected to the bottom side of the guide rail 3. A drive assembly 301 for driving the transmission seat 6 to move horizontally is provided on the guide rail 3. The mounting assembly 4 is fixedly connected to one end of the transmission seat 6, and a platform 402 is fixedly installed on the mounting assembly 4 via a column 401. An electric push rod 5 is fixedly installed on the upper end of the platform 402. A lifting seat 501 is fixedly installed on the telescopic end of the electric push rod 5. Two limiting blocks 7 slide through both sides of the assembly 4. A connecting rod 502 is movably hinged between the electric push rod 5 and the limiting blocks 7. A positioning protrusion 201 is provided on the slag-blocking plug 2. The assembly 4 is slidably sleeved on the outside of the positioning protrusion 201. A side groove 202 adapted to the limiting block 7 is opened on the side of the positioning protrusion 201. The limiting block 7 can be inserted into the side groove 202 of the positioning protrusion 201.

[0020] Among them, such as Figure 2 As shown, the drive assembly 301 includes a motor 302 and a lead screw shaft 303. The motor 302 is fixedly installed at one end of the guide rail 3, and the lead screw shaft 303 is fixedly connected to the drive end of the motor 302. The transmission seat 6 is threaded onto the lead screw shaft 303. The motor 302 drives the lead screw shaft 303 to rotate, which can drive the transmission seat 6 and the slag-blocking plug 2 to move horizontally.

[0021] Among them, such as Figure 1 As shown, a control panel 8 is fixedly installed on the outside of the frame 1. The output end of the control panel 8 is electrically connected to the input end of the telescopic cylinder 101, the motor 302 and the electric push rod 5.

[0022] Among them, such as Figure 3 As shown, two guide posts 102 are symmetrically fixedly installed inside the frame 1, and the guide rail 3 is slidably sleeved on the outside of the guide posts 102, so as to achieve the purpose of guiding the guide rail 3.

[0025] The working principle of this utility model:

[0026] By using the motor 302 to drive the lead screw shaft 303 to rotate, the transmission seat 6 and the slag-blocking plug 2 can be moved horizontally. The telescopic cylinder 101 drives the guide rail 3 to move up and down, which can move the slag-blocking plug 2 vertically. The position of the slag-blocking plug 2 can be adjusted according to the actual situation to block slag. If the slag-blocking plug 2 needs to be replaced, the electric push rod 5 drives the lifting seat 501 to move down. The connecting rod 502 drives the limiting block 7 to slide outward along the side of the mounting 4 until the limiting block 7 disengages from the side groove 202 of the positioning protrusion 201. The slag-blocking plug 2 can then be disassembled and replaced. If the replaced slag-blocking plug 2 needs to be installed, the mounting 4 is fitted onto the positioning protrusion 201 of the slag-blocking plug 2. The electric push rod 5 drives the lifting seat 501 to move up. The connecting rod 502 drives the limiting block 7 to slide inward along the side of the mounting 4 until the limiting block 7 is inserted into the side groove 202 of the positioning protrusion 201. The installation of the slag-blocking plug 2 is then completed and it can be used.
