Description

Technical Field

[0001] The utility model relates to the technical field of steel manufacturing, in particular to a cold material feeding device. Background Art

[0002] Continuous casting is an important process in steel production that turns liquid high-temperature molten steel into solid high-temperature ingots. The continuous casting machine crystallizer is a cooling component that turns molten steel into ingots. The continuous casting machine crystallizer is a continuous steel casting equipment that receives the molten steel injected from the tundish and solidifies it into a solid ingot shell according to the specified cross-sectional shape. It is the most critical equipment of the continuous casting machine.

[0003] The service life of the tundish of the seven-machine seven-strand square billet continuous casting machine is 36 hours. Each time the casting starts, the crystallizers of the seven strands must be sealed with ingots. Each strand takes 8-10 minutes to complete all the work. Since there are many strands involved, if there is a shortage of personnel, the preparation time before casting will be too long, which seriously reduces the production efficiency. In addition, the amount of cold material cannot be controlled when the cold material is placed manually. In order to solve the above problems, a quantitative barrel (such as publication number CN110385409A) has been introduced. The quantitative barrel is used to hold the cold material, which can not only control the amount but also reduce the preparation and placement time of the cold material.

[0004] However, the existing quantitative barrels mostly have a handle fixedly installed at the upper opening of the barrel, which seriously affects the docking between the quantitative barrel and the crystallizer mouth. When the cold material is added, the upper opening of the quantitative barrel cannot be close to the crystallizer mouth due to the limitation of the handle, and the cold material is easily scattered during the addition process. In addition, the handle is only convenient for the transfer, placement and removal of the quantitative barrel. When the cold material is added, the handle does not play an auxiliary role. The quantitative barrel is difficult to dump and cannot be quickly turned over and dumped, which is inconvenient to use. Utility Model Content

[0005] In order to solve the technical problems in the above-mentioned background technology that the existing quantitative material barrel is inconvenient to use and difficult to operate, the utility model provides a cold material feeding device.

[0006] The technical solution of this utility model is as follows:

[0007] The utility model provides a cold material delivery device, comprising: a box body with an upper opening, a first handle rotatably provided on the outer wall of the box body, and a second handle fixedly provided on the outer wall of the box body, the first handle is close to the upper opening of the box body, and the second handle is close to the bottom of the box body, the first handle is perpendicular to the second handle, the positions of the first handle and the second handle do not limit the fit between the upper opening of the box body and the crystallizer mouth, and the first handle is rotatably provided, and the second handle is fixedly provided, when the box body is turned over, the first handle plays a role of auxiliary limiting and supporting, and the second handle plays a role of applying force for turning, and the second handle is close to the bottom of the box body, which can save the force required for turning the box body, facilitates the turning of the box body, and reduces labor intensity.

[0008] Preferably, the first handle is arranged horizontally, and when the box body is flipped and tilted, the first handle can be used to limit the position of the box body to avoid displacement of the box body in the plane during the flipping process. The second handle is arranged vertically, which is more ergonomic and convenient for the staff to coordinate the force with both hands, thus greatly saving manpower.

[0009] Preferably, the first handle and the second handle are both U-shaped handles, which are convenient for holding.

[0010] Preferably, the first handle and the second handle are mounted on the same side outer wall of the box body to facilitate transfer and flipping of the box body.

[0011] Preferably, the first handle and the second handle are mounted on two opposite side outer walls of the box body, which facilitates the application of force and enables the box body to be turned over more quickly.

[0012] Preferably, the cross-section of the box body is rectangular, matching the shape of the square billet, and can control the placement of the cold material. It is convenient to adjust the position of the cold material after feeding, without the need to drastically adjust the position of the cold material, which greatly reduces the labor intensity of manual labor.

[0013] Preferably, a mounting seat is fixedly mounted on the outer wall of the box body, the mounting seat is close to the upper opening of the box body, two mounting seats are provided, a rotating shaft is rotatably provided between the two mounting seats, and the first handle is fixedly arranged on the rotating shaft to facilitate the installation of the first handle.

The first handle is close to the upper opening of the box body, and the second handle is close to the bottom of the box body. The first handle is perpendicular to the second handle. The positions of the first handle and the second handle do not limit the fit between the upper opening of the box body and the mouth of the crystallizer. The first handle is rotatably set, and the second handle is fixedly set. When flipping the box body, the first handle plays a role of auxiliary limiting and supporting, and the second handle plays a role of applying force to flip. The second handle is close to the bottom of the box body, which can save the force required for flipping the box body, facilitates quick flipping of the box body, facilitates the flipping of the box body, and reduces labor intensity.

[0021] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0022] In a typical implementation of the present invention, Figure 1 As shown, a cold material delivery device is proposed, comprising: a box body 1 and a first handle 2 and a second handle 3 installed on the box body 1.

[0023] The box body 1 is an upper opening structure, and the cross section of the box body 1 is rectangular. The box body 1 is welded by four side panels and a bottom plate. In this embodiment, the bottom plate is a 160*160mm square plate, and the side panels are 250*160mm plates. The side panels are welded and fixed to the bottom plate with a 160mm edge.

[0024] It can be understood that in other embodiments, the side panels and the bottom panel may also be of other sizes, which can be determined specifically according to the actual size of the billet, that is, the size of the box body 1 corresponds to the size of the billet, so as to play a quantitative role, and have standard quantity and shape specifications for the cold material, thereby ensuring the accuracy of the cold material discharge quantity.

[0025] A mounting seat 4 is fixedly installed on the outer wall of one side of the box body 1. The mounting seat 4 is fixedly connected to the box body 1 by welding. The mounting seat 4 is close to the upper opening of the box body 1. Two mounting seats 4 are provided, and the two mounting seats 4 are relatively arranged on the same side. A rotating shaft 5 is rotatably provided between the two mounting seats 4, and the first handle 2 is fixedly provided on the rotating shaft 5, so that the first handle 2 can rotate around the axis.

[0026] The second handle 3 is fixedly installed on the outer wall of one side of the box body 1 by welding. The second handle 3 is close to the bottom of the box body 1 to assist the use of the first handle 2, so as to facilitate the staff to take and transfer the box body 1, and to facilitate the rapid dumping of the box body 1, so as to quickly pour the cold material in the box body 1 vertically into the crystallizer. Further manual adjustment can ensure that the cold material is evenly distributed.

[0027] The first handle 2 and the second handle 3 are both U-shaped handles, and the first handle 2 is perpendicular to the second handle 3. Specifically, the first handle 2 is horizontally arranged, and the second handle 3 is vertically arranged (here the vertical placement state of the box body 1 is used as a reference, that is, the placement state when the upper opening is located at the top). The first handle 2 is rotatably connected to the box body 1 to play a role of limiting support during the dumping process. The second handle 3 is fixedly connected to the box body 1 and close to the bottom of the box body 1. The staff can dump the box body 1 quickly and easily under the action of the second handle 3.

[0028] In the present embodiment, the second handle 3 is located on the same side as the first handle 2, that is, the first handle 2 and the second handle 3 are both installed on the outer wall of the same side of the box body 1, the first handle 2 is located above the second handle 3, the first handle 2 is close to the upper opening of the box body 1, and the second handle 3 is close to the bottom of the box body 1; in other embodiments, the first handle 2 and the second handle 3 may also be respectively arranged on two opposite side outer walls of the box body 1, that is, the first handle 2 is rotatably arranged on the outer wall of one side of the box body 1, the first handle 2 is close to the upper opening of the box body 1, and the second handle 3 is relatively fixedly arranged on the outer wall of the other side of the box body 1, and the second handle 3 is close to the bottom of the box body 1; or, the first handle 2 and the second handle 3 are located on adjacent two side surfaces.

[0029] It can be understood that the specific setting position of the second handle 3 can be determined according to actual needs, as long as the second handle 3 is perpendicular to the first handle 2, and the first handle 2 is close to the upper opening of the box body 1, and the second handle 3 is close to the bottom of the box body 1. In this way, the box body 1 can be turned over quickly, labor-savingly and accurately, and the cold material in the box body 1 can be poured into the crystallizer.

[0030] The use of the cold material feeding device can prepare the cold material quickly and accurately. Since the volume inside the box body 1 is fixed, the accuracy of the amount of cold material fed is effectively guaranteed, making it more convenient to feed the cold material after the sealing and ingot introduction are completed each time the tundish is started for pouring, effectively shortening the production preparation time and greatly improving the operation rate of the continuous casting machine.

[0031] The specific working principle is:

[0032] First, place the cold material delivery device at the designated position, and vertically insert a number of cold materials into the box body 1 until the cold materials fill the box body 1, so as to realize the quantitative control of the cold materials;

[0033] Then the dummy rod is passed into the crystallizer, and the gap around the tie rod is sealed with asbestos;

[0034] After the plugging is completed, a layer of steel chips is spread on the top of the dummy bar;

[0035] The staff member carries the first handle 2 and transfers the cold material feeding device to the crystallizer mouth. The staff member fits one side of the upper opening of the cold material feeding device with one side of the crystallizer mouth. Then the staff member holds the second handle 3 with his other hand and applies force. Using the principle of leverage, the box body 1 is quickly turned over by the second handle 3 and vertically aligned with the crystallizer mouth, so that the cold material in the box body 1 is quickly and vertically poured into the crystallizer and its position is manually adjusted to make the cold material evenly distributed.

[0036] The provision of the first handle 2 and the second handle 3 not only facilitates the overall transfer and flipping of the cold material delivery device, facilitates use, and saves manpower, but also does not hinder the close fit between the opening of the box body 1 and the crystallizer mouth, thereby avoiding the scattering of the cold material.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
