Therefore, the four corners of the billet are cut off manually using flames to solve the above problems. In addition, the types and quantities of alloy elements added to the billet are also increasing, but some elements (such as Nb, B and other elements) are very likely to cause cracks in the corners of the material, and they cannot be directly put into the furnace. It is necessary to wait for the billet to cool down and then manually clean the corners.

[0040] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0041] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0042] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] In the related art, with the advancement of medium and thick plate production technology, the rolling width of medium and thick plate steel plates is increasing. At present, the rolling mill width of many domestic steel mills has exceeded 5000mm, and some steel mills have reached 5500mm. However, the width of the continuous casting billet is relatively narrow. At present, the maximum billet width is only about 3000mm, and most steel mills are still below 2500mm. However, when using narrow billets to roll wide-width steel plates, due to the excessive width ratio, folding defects often occur at the edges of the steel plates. At present, most steel mills use manual flames to cut off the four corners of the billet to solve the above problems. In addition, the types and quantities of alloy elements added to the billet are also increasing, but some elements (such as Nb, B and other elements) are very likely to cause cracks in the corners of the material, and they cannot be directly put into the furnace. After the billet is cooled, it is necessary to manually clean the corners. However, there are also some problems with manually cleaning the billet, such as slow cleaning speed, inability to clean at high temperature, and inability to achieve standardization of edge cleaning quality, which will lead to the inability to achieve hot delivery of the billet, seriously affecting production efficiency and wasting energy.

[0044] The present application provides a blank processing device, which sets up a movable frame on a blank table, sets a cutting assembly of a cutting device on the movable frame, uses a guide and positioning assembly of the movable frame to position and guide the relative position of the frame and the blank on the blank table, and uses a driving mechanism of the movable frame to control the movement of the frame, so that the edges and corners of the blank in the production process can be automatically cleaned without cooling the blank. When the processing device processes the edges and corners of the blank, it can not only ensure the accuracy of the edge and corner cutting processing, but also improve the efficiency of edge and corner processing, which is faster than manual processing.

[0045] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and implementation methods can be combined with each other if there is no conflict.

[0046] In an exemplary embodiment of the present utility model, a blank processing device is provided, such as Figure 1 As shown, Figure 1 1 is a schematic diagram of a billet processing device according to an exemplary embodiment. The processing device includes: a billet table 20, a cutting device 40 and a movable frame 10. The processing device can be used to process the billet 30, such as processing a continuous casting billet with corner defects.

[0047] The blank table 20 is used to lift the blank 30. The cutting device 40 includes: a cutting assembly, which is used to cut the corners of the blank 30. The movable frame 10 includes: a frame, on which the cutting assembly is arranged; a guide positioning assembly, which is arranged on the frame, and is used to locate the relative position of the frame and the blank 30 and guide the frame during the movement of the frame; and a driving mechanism 107, which is used to drive the frame to move, so as to cooperate with the cutting assembly to form a preset cutting trajectory.

[0048] In this exemplary embodiment, after the blank 30 is placed on the blank table 20, the position of the frame is adjusted to correspond to the blank 30; then the guide positioning assembly is adjusted to position the relative position of the frame and the blank table 20; after the cutting device 40 is started, the driving mechanism 107 drives the frame to move, and at the same time uses the guide positioning assembly to guide the moving direction of the frame, so that the cutting device 40 can move along a preset direction, thereby forming a preset cutting track on the blank 30. The processing equipment can automatically complete the cleaning process of the corners of the blank 30 or can be completed by manual remote operation after being configured with a controller with a corresponding program. When processing the corners of the blank 30 based on the processing equipment, not only can the corner cutting processing accuracy be guaranteed, but also the corner processing efficiency can be improved, which is faster than manual.

[0049] In some exemplary embodiments, Figure 1 and Figure 2 As shown, in this exemplary embodiment, considering the different widths of the blanks 30, in order to achieve the cleaning of the corners of the blanks 30 of different sizes, the movable frame 10 is also optimized. Exemplarily, the movable frame 10 also includes: a frame adjustment component, which is used to adjust the frame width of the frame to make it adapt to the width of the blank 30.

[0050] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the frame can adopt a "door-type" structure. Exemplarily, the frame body of the frame can be constructed as two brackets that cooperate with each other. In this embodiment, the frame includes: a first bracket 101 and a second bracket 102, wherein the first bracket 101 and the second bracket 102 are both inverted "L-shaped" structures.

[0051] Specifically, the first bracket 101 includes: a first column 101A located on one side of the blank platform 20, a first cross frame 101B is provided on the upper part of the first column 101A, and a pulley 106 is provided on the lower part of the first column 101A. The second bracket 102 includes: a second column 102A located on the other side of the blank platform 20, a second cross frame 102B slidably connected to the first cross frame 101B is provided on the upper part of the second column 102A, and a pulley 106 is provided on the lower part of the second column 102A. At this time, the frame width can be understood as the distance between the first column 101A and the second column 102A, and the relative position relationship between the first cross frame 101B and the second cross frame 102B is adjusted by the frame adjustment component to change the frame width of the frame. The driving mechanism 107 includes a motor and a motor controller, and the motor is used to drive the pulley 106 below the frame; the corresponding motor controller is used to control the travel speed of the motor and the pulley 106.

[0052] Optionally, a first slide hole 1011 is provided on both the first cross frame 101B and the second cross frame 102B, and the frame adjustment assembly uses bolts and nuts. After the first slide hole 1011 on the first cross frame 101B and the first slide hole 1011 on the second cross frame 102B are aligned up and down, two first slide holes 1011 are pierced from top to bottom or from bottom to top with bolts; then the first cross frame 101B and the second cross frame 102B are locked by using nuts and bolts. When the width of the frame needs to be adjusted, the nuts are first unscrewed, and the corresponding first bracket 101 and the second bracket 102 are adjusted to a suitable position, and then the nuts are tightened. It should be noted that the number of first slide holes 1011 on the first cross frame 101B and the second cross frame 102B can be designed according to actual needs. For example, in order to improve the stability of the first bracket 101 and the second bracket 102 after assembly, two parallel first slide holes 1011 can be set on the first cross frame 101B; correspondingly, two parallel first slide holes 1011 are also set on the second cross frame 102B to cooperate with the first cross frame 101B.

[0053] In some exemplary embodiments, after the blank 30 is placed on the blank table 20, the positions of the blank 30 and the blank table 20 are relatively fixed. In order to achieve the relative position relationship between the positioning frame and the blank 30 so as to facilitate the processing of the corners of the blank 30, the relative position relationship between the frame and the blank table 20 can be positioned.

[0054] Considering that when processing the edges and corners of the blank 30, the frame needs to move along the length direction of the blank 30, at this time, the moving direction of the frame can be guided by setting a positioning guide wheel to roll along the side of the blank table 20. Exemplarily, the guiding and positioning assembly includes: a first positioning guide wheel 105, which is arranged on the first column 101A; a second positioning guide wheel 109, which is arranged on the second column 102A; wherein the first positioning guide wheel 105 corresponds to the second positioning guide wheel 109.

[0055] In this embodiment, the first positioning guide wheel 105 and the second positioning guide wheel 109 are first used to locate the frame width on both sides of the blank table 20. Then, when processing the corners of the blank 30, the two positioning guide wheels are correspondingly arranged on both sides of the blank table 20 and in rolling contact with it, thereby forming a guide for the frame, which is convenient for processing the corners of the blank 30.

[0056] In some exemplary embodiments, Figure 1 and Figure 2 As shown, considering that the heights of different blank tables 20 may be different, in order to adapt to more types of blank tables 20, the connection method between the guide positioning assembly and the frame is also optimized. In this embodiment, the first positioning guide wheel 105 and the second positioning guide wheel 109 are respectively equipped with corresponding height adjustment members to connect with the frame. Exemplarily, the guide positioning assembly also includes: a first height adjustment member 103, which is used to adjust the position height of the first positioning guide wheel 105 on the first column 101A; a second height adjustment member 104, which is used to adjust the position height of the second positioning guide wheel 109 on the second column 102A.

[0057] Specifically, a second slide hole 1012 is provided on the first column 101A, and screw rods and corresponding nuts are formed on the first height adjustment member 103 and the second height adjustment member 104. After the screw rods on the corresponding height adjustment members are passed through the second slide hole 1012, the nuts are used to lock them. When the height of the corresponding positioning guide wheel needs to be adjusted, the nuts are first unscrewed, and after the corresponding positioning guide wheel is adjusted to a suitable height, the nuts are tightened.

[0058] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the cutting assembly includes: a flame cutting nozzle 401 and oxygen and acetylene pipelines 404. The flame cutting nozzle 401 is used to cut the edges and corners of the blank 30. The flame cutting nozzle 401 can be set on the frame, such as on the columns (the first column 101A and the second column 102A) and / or the cross frame (the first cross frame 101B and the second cross frame 102B). The rear of the flame cutting nozzle 401 is connected to the oxygen and acetylene pipeline 404, which can spray flame to clean / cut the edges and corners of the blank 30.

[0059] Considering the different sizes and heights of the blank table 20 and the blank 30, the cutting assembly arranged on the corresponding column may interfere with the blank table 20 or the blank 30 when the frame moves, or the cutting position may be inappropriate. In this embodiment, the connection mode of the flame cutting nozzle 401 is also optimized. Exemplarily, the cutting device 40 includes: a retractable connecting rod 402, which is used to adjust the position height of the flame cutting nozzle 401. The first end of the retractable connecting rod 402 is connected to the frame, and the second end of the retractable connecting rod 402 is connected to the flame cutting nozzle 401.

[0060] Optionally, the telescopic connecting rod 402 can be arranged obliquely, that is, the first end of the telescopic connecting rod 402 is connected to the inner side of the first column 101A or the inner side of the second column 102A or the lower side of the first cross frame 101B or the lower side of the second cross frame 102B, and the second end of the telescopic connecting rod 402 is located between the first column 101A and the second column 102A and forms an acute angle with the vertical direction. This method can not only adjust the height of the flame cutting nozzle 401, but also avoid interference with the blank 30 or the blank table 20 as much as possible.

[0061] In some alternatives of this embodiment, a folding connecting rod may also be used. It should be noted that, whether it is a folding connecting rod or a telescopic connecting rod 402, as long as the height of the position of the flame cutting nozzle 401 can be adjusted. When a folding connecting rod is used, its connection method is similar to that of the telescopic connecting rod 402, and will not be repeated here.

[0062] In order to more accurately cut the edges and corners of the blank 30, the connection between the flame cutting nozzle 401 and the telescopic connecting rod 402 can also be optimized. Exemplarily, the cutting device 40 also includes: an adjustable shaft 403, which is arranged at the second end of the telescopic connecting rod 402 and is used to adjust the cutting angle of the flame cutting nozzle 401.

[0063] In some exemplary embodiments, Figure 1 and Figure 2 As shown, considering that the four corners of the blank 30 need to be cleaned and cut off, in order to improve the cleaning efficiency, the number of flame cutting nozzles 401 in the cutting assembly is adjusted and optimized. Exemplarily, the cutting assembly includes: four flame cutting nozzles 401. The four flame cutting nozzles 401 are divided into two groups, wherein two flame cutting nozzles 401 are correspondingly arranged on one side of the frame, for cutting the upper and lower corners of the corresponding side of the blank 30; two flame cutting nozzles 401 are correspondingly arranged on the other side of the frame, for cutting the upper and lower corners of the corresponding side of the blank 30.

[0064] In this embodiment, if Figure 1 and Figure 2As shown, the directions of the retractable connecting rods 402 of the two flame cutting nozzles 401 arranged on the same side are different. The retractable connecting rod 402 of the upper corner of the cutting blank 30 is arranged obliquely upward, and the retractable connecting rod 402 of the lower corner of the cutting blank 30 is arranged obliquely downward.

[0065] In some exemplary embodiments, Figure 1 and Figure 2 As shown, the blank table 20 is an H-shaped steel frame. The H-shaped steel frame includes: two vertical plates and a horizontal plate, the two vertical plates are arranged opposite to each other and the middle parts of the two vertical plates are connected by the horizontal plate.

[0066] The width distance of the processing equipment for the billet 30 provided in the above embodiment is adjustable, and can cope with billets of different widths; the bottom of the frame is equipped with wheels and does not rely on tracks; in addition, 4 corners can be cut at one time, and it has the characteristics of easy operation, flexible transfer, high temperature resistance, and high efficiency.

[0067] When the edge of the billet needs to be cleaned, first lift the billet by the overhead crane and place it on the H-shaped steel frame (lifting frame). Move the movable frame 10 to the front end of the billet, adjust the width of the upper frame by the frame adjustment component, and adjust the height of the guide positioning component by the height adjustment member, so that the corresponding positioning guide wheels on the side are in contact with the side of the billet. Adjust the flame cutting nozzle 401 to align with the four corners of the billet, ignite the flame nozzle, start the motor power supply and adjust the speed by the motor controller, and the flame cutting equipment starts to cut the four corners of the billet.
