Description

Technical Field

[0001] The utility model relates to the technical field of trimming devices, in particular to a trimming device for producing high-performance magnesia-carbon bricks for steelmaking converters. Background Art

[0002] The steelmaking converter uses molten iron, scrap steel, and ferroalloys as the main raw materials. It does not rely on external energy sources, but relies on the physical heat of the molten iron itself and the heat generated by the chemical reactions between the molten iron components to complete the steelmaking process in the converter. The converter is mainly used to produce carbon steel, magnesia carbon bricks, alloy steel, and copper and nickel smelting.

[0003] Magnesia carbon bricks are non-burning carbon composite refractory materials made of high-melting-point alkaline oxide magnesium oxide (melting point 2800℃) and high-melting-point carbon materials that are difficult to be wetted by slag as raw materials, with various non-oxide additives added and combined with carbon binders.

[0004] In order to improve the aesthetics and surface smoothness of magnesia carbon bricks, the bricks are currently polished and trimmed. However, the dedicated large-scale trimming machine equipment is large and inconvenient to move and carry, while the trimming method of a small polishing machine is not efficient; therefore, it does not meet the existing needs.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] like Figure 1-5 As shown, the utility model provides a high-performance magnesia-carbon brick production and trimming device for steelmaking converters, including a conveyor mounting frame 1 and a conveyor belt 2. A trimming frame 4 is provided above the conveyor belt 2. The inner walls of the trimming frame 4 are rotatably connected to a first grinding roller 10 and a second grinding roller 11, respectively. The first grinding roller 10 and the second grinding roller 11 are connected by a belt drive.

[0027] A clamping rubber pad 8 is provided between the first grinding roller 10 and the second grinding roller 11 , and a bow-shaped limit frame 15 is fixedly connected to the back of the clamping rubber pad 8 . An infrared positioning probe 13 is fixedly connected to the inner wall of the trimming frame 4 near one end.

[0028] One end of the first grinding roller 10 is connected to the driving motor 12 located at the top of the trimming frame 4 through a belt drive. The bottom surface of the trimming frame 4 is fixedly connected to a sliding bottom block 14. One side of the sliding bottom block 14 is fixedly connected to a double-acting cylinder 9. The bottom surface of the trimming frame 4 is slidably connected to the supporting bottom frame 6. The upper surface of the supporting bottom frame 6 is provided with a slide groove 16. The outer wall of the double-acting cylinder 9 is fixedly connected to the inner wall of the supporting bottom frame 6.

[0029] like Figure 1-5As shown, based on Example 1, the present invention provides a technical solution: preferably, the inner wall of the slide groove 16 is slidably connected to the outer wall of the sliding bottom block 14, and the bottom surface of the supporting bottom frame 6 is fixedly connected to the bottom frame support leg 7. The side of the arched limit frame 15 away from the clamping rubber pad 8 is fixedly connected to the inner wall of the trimming frame 4.

[0030] A guide telescopic rod 5 is fixedly connected to the top center of the trimming frame 4 .

[0031] There are two groups of trimming frames 4 , which are symmetrically distributed above the conveyor belt 2 .

[0032] The following is a detailed description of the working principle of the high-performance magnesia carbon brick production trimming device for steelmaking converters.

[0033] like Figure 1-5 As shown, when the magnesia carbon brick needs to be trimmed, it is placed horizontally on the surface of the conveyor belt 2, and then the conveyor belt 2 is started. At this time, the conveyor belt 2 will drive the magnesia carbon brick to start moving toward the position of the trimming frame 4. When the infrared positioning probe 13 detects the specified position of the movement of the magnesia carbon brick, the detection signal is fed back to the external controller. At this time, the controller controls the conveyor belt 2 to stop running and starts the double-acting cylinder 9, so that the two ends of the double-acting cylinder 9 begin to shrink, and then pull the trimming frames 4 at both ends closer to each other, and use the clamping rubber pad 8 to clamp and fix the side of the magnesia carbon brick. When the double-acting cylinder 9 is started, the drive motor 12 is also started synchronously. The drive motor 12 drives the first grinding roller 10 and the second grinding roller 11 to rotate through the belt. When the first grinding roller 10 and the second grinding roller 11 are in contact with the side of the magnesia carbon brick, they will perform the grinding work.

[0034] After the grinding is completed, the double-acting cylinder 9 starts to push the trimming frame 4 to the initial position. After the trimming frame 4 is reset, the infrared positioning probe 13 is located on the side of the magnesia carbon brick and will not affect its movement.

[0035] When the double-acting cylinder 9 pulls the trimming frame 4 to move, the sliding bottom block 14 slides on the inner wall of the slide groove 16, and the guide telescopic rod 5 also starts to shrink synchronously to guide and limit the movement of the trimming frame 4.

[0036] When the magnesia carbon bricks are transported on the conveyor belt 2, the guide pulley 17 in the guide frame 3 can fit into the side of the magnesia carbon bricks to limit the movement of the magnesia carbon bricks so that they always move in parallel with the trimming frame 4, thereby ensuring the subsequent first grinding roller 10 and the second grinding roller 11 to achieve a good grinding effect on the side of the magnesia carbon bricks.

[0037] The conveyor belt 2 is a hollow conveyor belt with multiple sets of support rollers at the bottom to ensure that the magnesia carbon bricks do not move downward during transportation, avoiding the problem that the first grinding roller 10 and the second grinding roller 11 cannot perform fixed-point trimming on them.

[0038] By using the trimming frame 4, the first grinding roller 10, the second grinding roller 11, the supporting bottom frame 6, the sliding bottom block 14, the conveyor belt 2 and the double-acting cylinder 9, the magnesia carbon brick can grind four edges at the same time, thereby greatly improving the grinding efficiency of the staff.

[0039] By using the conveying mounting frame 1, the conveyor belt 2, the guide frame 3 and the guide pulley 17 in combination, the magnesia carbon bricks only need to be placed on the conveyor belt 2 when being polished, and transported to the polishing area through the conveyor belt 2 to complete the subsequent polishing work, thereby reducing the tediousness of the staff's operation and increasing the convenience of the equipment.

[0040] It should be noted that, in this document, relational terms such as first and second, etc., are used solely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, the terms "comprise," "include," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or device comprising a set of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. Without further limitation, an element defined by the phrase "comprising a..." does not preclude the presence of other identical elements in the process, method, article, or device comprising the element. While the present invention has been generally described above, modifications or improvements based on this invention are readily apparent to those skilled in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of this invention.
