Problems solved by technology

[0003] With the advancement of technology, enterprises have more and more demands for single-tundish multi-strand casting machines. In three-strand slab continuous casting machines, due to the large flow spacing and large molten steel capacity of a single tundish, the tundish load will reach 100 For this working condition, the current design usually uses the high and low rail tundish car in the multi-strand billet continuous casting machine. The fulcrum of the tundish on the tundish car is on both sides of the tundish length direction. Tundish car structure, when the length of the tundish reaches 9 meters or more, because the distance between the support points is basically the same as the length of the tundish, the stress in the middle of the tundish deteriorates seriously, and the stress and deformation of the tundish are very large , due to the high frequency of use of the tundish, the long use time, and the high-temperature flowing molten steel loaded, the harsh stress situation seriously affects the service life and production safety of the tundish

Embodiment 1

[0037] This embodiment provides a three-stream double low-gauge tundish car, including horizontal low-gauge beams 1 and door-shaped low-gauge beams 6 arranged in parallel and of the same height. The horizontal low-gauge beams 1 are arranged on the continuous casting machine On the outer arc side, the door-shaped low-rail car beam 6 is arranged on the inner arc side of the continuous casting machine. There are three pouring positions on the inner arc side of the continuous casting machine, which are respectively located on both sides of the door-shaped low-rail car beam 6 and centre position;

[0038] The horizontal low-rail car beam 1 and the door-shaped low-rail car beam 6 are connected through the car-beam connecting frame 2 to form a frame body, and the horizontal low-rail car beam 1 is provided with driving wheels 10, and the door-shaped low-rail car The beam 6 is provided with a driven wheel, the horizontal low-rail car beam 1 and the door-shaped low-rail car beam 6 are f...

Embodiment 2

[0042] On the basis of Embodiment 1, this embodiment provides a three-stream double low-rail tundish car, the horizontal low-rail car beam 1 and the door-shaped low-rail car beam 6 are provided with a guide frame 7, and the U-shaped lifting The frame 3 is slidably connected with the guide groove of the guide frame 7 .

[0043] The fixed end of the lifting drive device 8 and the guide frame 7 are fixed on the horizontal low-rail car beam 1 and the door-shaped low-rail car beam 6, and the U-shaped lifting frame 3 is connected with the movable end of the lifting drive device 8. Under the guiding action, the U-shaped lifting frame 3 is moved in the vertical direction to realize the lifting movement.

Embodiment 3

[0045] On the basis of Embodiment 1, this embodiment provides a three-stream double low-gauge tundish car, which also includes a centering device 5 fixed on the cantilever beam on the side of the U-shaped lifting frame 3 .

[0046] The centering device 5 is used to center the nozzle of the tundish in the crystallizer.

[0047] For the three-strand slab continuous casting machine, three pouring positions are required on the inner arc side, and their positions correspond to the position of the tundish nozzle. The pouring positions at both ends are vacated by the two sides of the gate-shaped low-gauge rail car beam 6, and the pouring position in the middle position is to vacate the operation space in the gate-shaped position, so as to achieve the purpose of pouring three-strand slabs.

Abstract

The invention provides a three-flow double-low-rail tundish vehicle and a using method of the three-flow double-low-rail tundish vehicle. The vehicle comprises a horizontal low rail vehicle beam and adoor type low rail vehicle beam which are arrange in parallel and equal in height. The horizontal low rail vehicle beam is arranged on the outer arc side of a continuous casting machine, the door type low rail vehicle beam is arranged on the inner arc side of the continuous casting machine, the inner arc side of the continuous casting machine is provided with three casting sites which are locatedon the two sides and middle of the door type low rail vehicle beam correspondingly, the horizontal low rail vehicle beam and the door type low rail vehicle beam are connected through a vehicle beam connecting frame to form a vehicle frame main body, a driving wheel is arranged on the horizontal low rail vehicle beam, a driven wheel is arranged on the door type low rail vehicle beam, a lifting driving device is fixedly arranged on the horizontal low rail vehicle beam and the door type low rail vehicle beam, the movable end of the lifting driving device is fixedly provided with a U-shaped lifting frame, and a weighing device is arranged on the U-shaped lifting frame. According to the two-low-rail tundish vehicle with the structure, compared with the structure of an existing high-low-rail tundish vehicle, the stress condition of a borne tundish is greatly improved, and stress concentration of the vehicle body is relieved in the case of large load.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, and in particular relates to a three-stream double-low-gauge tundish car and a using method thereof. Background technique [0002] The main function of the continuous casting machine tundish car is to carry the tundish, realize the functions of walking, tundish lifting and nozzle alignment, and it plays a very important role in the continuous casting machine. [0003] With the advancement of technology, enterprises have more and more demands for single-tundish multi-strand casting machines. In three-strand slab continuous casting machines, due to the large flow spacing and large molten steel capacity of a single tundish, the tundish load will reach 100 For this kind of working conditions, the existing design usually uses the high and low rail tundish car in the multi-strand billet continuous casting machine. The fulcrum of the tundish on the tundish car is on both sides o...
