Description

Technical Field

[0001] The invention belongs to the technical field of crystallizers, and in particular relates to a method for adjusting the width and preventing cone runaway of a continuous casting machine crystallizer. Background Art

[0002] The crystallizer is a very important part of the continuous casting machine. It is a bottomless steel ingot mold with forced water cooling. It is called the "heart" of the continuous casting equipment. The continuous casting crystallizer is a molten steel cooling and molding equipment. It is basically composed of a frame, a water tank and a copper plate (back plate and copper plate), an adjustment system (adjustment device, reducer, etc.); a lubrication system (oil pipe oil circuit), a cooling system and a spraying system.

[0003] The taper of the crystallizer is usually strictly set according to the type of steel and the cross-section of the continuous casting machine. Once set, it is not allowed to change during the normal production process, otherwise it will change the cooling effect of the ingot, causing defects such as cracks in the corners of the ingot, bulging on the narrow side, and local depression on the narrow side. In severe cases, corner cracks and bulging-type steel leakage will occur, damaging the equipment and reducing the operating rate of the continuous casting machine and the service life of the crystallizer, directly affecting the company's benefits.

[0004] However, when the existing continuous casting machine crystallizer is crystallizing into steel pipes, due to the different diameters of the required steel pipes, when the steel pipes are cut, it is easy to encounter a situation where the steel pipes and the conical surface in the crystallizer are stuck when the steel pipes have a larger diameter, resulting in the inability to cut the steel pipes. If the conical surface in the crystallizer is larger, it will not be able to guide the cutting of the steel pipes.

In this setting, when the first concave plate 401 and the second concave plate 4011 are subjected to the extrusion force of the first flip plate 301 and the second flip plate 3011, the first concave plate 401 and the second concave plate 4011 can be assisted by the fifth sliding mechanism provided in the inner cavity of the built-in mounting shell 1021 and the movable chutes 402 starting from the first concave plate 401 and the second concave plate 4011, so that the first concave plate 401 and the second concave plate 4011 can move horizontally and vertically, so that the width of the discharge point of the inner cavity of the crystallizer can be adjusted.

[0062] The implementation principle of the method for adjusting the width and preventing the cone from running of a continuous casting machine crystallizer in this embodiment is as follows:

[0063] First, when the molten steel is injected into the steel billet, it can enter the inner cavity of the upper installation shell 101 from the feed port 1014 provided at the upper installation shell 101 provided on the installation unit 100;

[0064] At this time, the staff can control the servo motor 201 to operate through the controller according to the size of each batch of steel billets (i.e., the maximum diameter of the steel pipe). When the servo motor 201 operates, it can drive the threaded rod 2011 to rotate. When the threaded rod 2011 rotates, it can drive the threaded sleeve 2012 to move horizontally downward with the assistance of the first sliding mechanism (because two symmetrical fixing plates 2013 are fixedly installed on the threaded sleeve 2012, and the two fixing plates 2013 are respectively connected to the first slider 2021 in the first sliding mechanism, wherein the first slider 2021 can slide on the first slide groove 202, so that the threaded sleeve 2012 and the fixing plate 2013 can be ensured to move horizontally downward).

[0065] When the fixing plate 2013 moves horizontally downward, it will be able to drive the fixing rod 203 to move horizontally downward, and when the fixing rod 203 moves horizontally downward, it will be able to drive the mounting plate 2031 to move horizontally downward, because the mounting plate 2031 is provided with a second sliding mechanism and a third sliding mechanism at the bottom, wherein the second sliding block 2041 and the third sliding block 2043 in the second sliding mechanism and the third sliding mechanism are respectively connected to the first rotating disk 302 and the positioning plate 3021 provided on the second rotating disk 3022, so when the mounting plate 2031 moves horizontally downward, it will be able to drive the two positioning plates 3021 to respectively drive the first rotating disk 302 and the second rotating disk 3022 to rotate with the assistance of the rotating rod 3012;

[0066] When the two rotating rods 3012 rotate, they can respectively drive the first flip plate 301 and the second flip plate 3011 to rotate. When the first flip plate 301 and the second flip plate 3011 rotate, they can drive the arc plug plate 1031 to move with the assistance of the fourth sliding mechanism, so that the arc plug plate 1031 can always fit on the first flip plate 301 and the second flip plate 3011, thereby playing a sealing role.

[0067] Because the first flip plate 301 and the second flip plate 3011 are hinged to the first concave plate 401 and the second concave plate 4011 respectively, when the first flip plate 301 and the second flip plate 3011 flip, the first concave plate 401 and the second concave plate 4011 can be driven to move in opposite directions, and because the first concave plate 401 and the second concave plate 4011 are plugged into each other through the rectangular plug-in plate 4013 and the rectangular plug-in groove 4012, it can be ensured that the first concave plate 401 and the second concave plate 4011 are always rectangular;

[0068] When the first concave plate 401 and the second concave plate 4011 are subjected to the extrusion force of the first flip plate 301 and the second flip plate 3011, the first concave plate 401 and the second concave plate 4011 can, with the assistance of the fifth sliding mechanism arranged in the inner cavity of the built-in mounting shell 1021 and the assistance of the moving slide groove 402 starting from the first concave plate 401 and the second concave plate 4011, allow the first concave plate 401 and the second concave plate 4011 to move horizontally and vertically, thereby being able to adjust the width of the discharge point of the inner cavity of the crystallizer, and at the same time, by changing the angle of the first flip plate 301 and the second flip plate 3011, it can play an auxiliary role when unloading different steel billets, thereby avoiding the situation where the larger steel billet is stuck at the taper formed by the first flip plate 301 and the second flip plate 3011.
