Abstract
Description
Technical Field
[0001] The utility model relates to a multi-vehicle linkage type slab flame cutting device, belonging to the technical field of slab production equipment in the metallurgical industry. Background Art
[0002] In slab production, the cutting of continuous casting ingots often relies on flame cutting, which often uses two cutting processes: primary cutting and secondary cutting. The primary cutting cuts the ingots into three or two times the size, and then the secondary cutting is performed to cut the appropriate size that meets the requirements. The secondary cutting requires the ingots to stay on the conveyor roller for cutting. Therefore, the temperature of the ingots will be lost during the cutting process, affecting the temperature of the ingots, which will increase the heating energy consumption of steel rolling in the future, resulting in increased costs, which is not conducive to the green production principle of steel.
[0003] In view of the above situation, it is urgent to develop a multi-vehicle linkage slab flame cutting device, which can complete the size cutting of the ingot in one cutting process by adopting a multi-vehicle linkage method, reduce the heat loss of the ingot during the second cutting and the time for heating the ingot in subsequent processes, and reduce production costs.

[0009] The limiter on the cutting vehicle is on the same plane as the movement plane of the cutting gun on the cutting vehicle, and the height is lower than the upper surface of the track.
[0010] The limit on the cutting vehicle cooperates with the limit stopper.
[0011] There are four cutting vehicles on the track, three on the conveying roller and one on the rear acceleration roller.

[0016] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0017] See attached Figure 1 A multi-vehicle linkage slab flame cutting device comprises a track 1, a cutting vehicle 2, a pressure head 3, a limiter 4, a cutting gun 5, a limit block 6, a laser rangefinder 7, a conveying roller 10 and a rear acceleration roller 11. The conveying roller 10 and the rear acceleration roller 11 are arranged in sequence according to the running direction of the ingot. The conveying roller 10 and the rear acceleration roller 11 are both provided with a limit block 6, and the rear acceleration roller 11 is also provided with a laser rangefinder 7; the track 1 is arranged on the conveying roller 10 and the rear acceleration roller 11, and multiple cutting vehicles 2 are arranged on the track 1, and each cutting vehicle 2 is provided with a pressure head 3, a limiter 4 and a cutting gun 5.
[0018] In this embodiment, a three-fold fixed-length billet is taken as an example. Figure 1 There are four cutting vehicles 2 on the track 1, three on the conveying roller 10, and one on the rear acceleration roller 11. There are two laser rangefinders 7 on the rear acceleration roller 11, and the two laser rangefinders 7 are arranged beside the rear acceleration roller 11. The limit block 6 is arranged on the upper part of the outer side of the rollers of the conveying roller 10 and the rear acceleration roller 11. The pressure head 3 is arranged at the lower part of the cutting vehicle 2, the limit 4 is arranged on the outer side of the cutting vehicle 2, the encoder 8 is arranged on the cutting vehicle 2, and the limit position 9 is arranged in front of the cutting vehicle 2, wherein:
[0019] The track 1 is located at the upper edge of the conveying roller 10 and the rear accelerating roller 11, and the conveying roller 10 and the rear accelerating roller 11 have the same width.
[0020] The height of the limit stopper 6 is the same as the height of the track 1, the length of the limit stopper 6 is equal to the outer diameter of the rollers on the conveying roller 10 and the rear acceleration roller 11, and the edge of the limit stopper 6 is aligned with the roller surfaces of the conveying roller 10 and the rear acceleration roller 11, and the limit stopper 6 corresponds one to one with the rollers on the conveying roller 10 and the rear acceleration roller 11.
[0021] The limiter 4 is on the same plane as the movement plane of the cutting gun 5 on the cutting vehicle 2 , and its height is slightly lower than the upper surface of the track 1 .
[0022] Here’s how it works:
[0023] Taking the three-times fixed-length ingot as an example, the ingot passes through the conveying roller 10 and is observed by the laser rangefinder 7. At the same time, the cutting car 2 on the track 1 calculates the position of the encoder 8 on the cutting car 2 and the position of the ingot observed by the laser rangefinder 7 through the program. The cutting car 2 moves on the track 1. After reaching the appropriate size, the pressure heads 3 on the three cutting cars 2 closest to the casting direction are pressed down to accurately keep the cutting car 2 and the ingot moving synchronously. During the movement, the limit 4 on the cutting car 2 touches the limit block 6 and generates a signal. The gas volume of the cutting gun on the cutting car 2 is reduced to avoid cutting the rollers of the conveying roller 10 or the rear acceleration roller 11. As the ingot moves forward, when the limit 4 on the cutting car 2 is out of contact with the limit block 6, the gas volume of the cutting gun 5 on the cutting car 2 is restored and cutting continues. If the cutting process If one of the four cutting vehicles 2 fails, the cutting vehicle in the lower pouring direction will replace the previous cutting vehicle to complete the cutting task. When the billet needs to be recut, the cutting vehicle 2 farthest from the pouring direction will be driven to the billet that needs to be recut through the track 1. After reaching the appropriate size, the pressure head 3 is lowered to press the billet, so that the cutting vehicle 2 and the billet move synchronously. After starting, the roller 11 is accelerated, and the billet that needs to be cut is separated from the uncut billet and the conveying speed is restored. The cutting vehicle 2 farthest from the pouring direction will perform the recutting. Since the billet that needs to be recut is at a distance from the uncut billet, it does not affect the observation and implementation of the subsequent cutting by the laser rangefinder 7. After the cutting is completed, the billet is accelerated on the rear acceleration roller 11 to separate the cut billet from the uncut billet, which is convenient for the laser rangefinder 7 to observe and measure the distance and implement the next cutting.
