Abstract
The utility model discloses a but long mouth of a river manipulator support of quick replacement trunnion ring, including the support body, the support body is that two about the U font have bear the arm, bears and is setting up a trunnion ring gudgeon pole hole on the arm for a left side, bears arm upper portion on the right side and is setting up one towards support body back open-ended U font slope slide, during the use, one side gudgeon of trunnion ring slides to slope slide bottom, the opposite side gudgeon of trunnion ring insert the trunnion ring gudgeon pole hole in.
Description
Technical Field
The utility model relates to a but long mouth of a river manipulator support of quick replacement backing ring. Is a modified design aiming at the continuous casting long nozzle manipulator bracket of the prior steel plant.
Background
When the molten steel in the ladle is poured into the tundish, in order to reduce secondary oxidation of the molten steel, temperature drop of the molten steel and avoid splashing of the molten steel to the maximum extent, a long nozzle is sleeved at the lower end of a sliding nozzle at the bottom of the ladle, one end of the long nozzle is connected with a ladle lower nozzle, the other end of the long nozzle is inserted into the molten steel in the tundish, and argon is blown into a bowl of the long nozzle for sealing protection pouring. The process is called protective pouring of ladle molten steel. The partial system consists of a manipulator, a manipulator bracket, a long nozzle backing ring and an argon sealing system.
The long nozzle ring support is connected to the manipulator through four bolts in the casting process, the long nozzle ring is installed in two grooves in the support and is subjected to anti-drop stop iron welding treatment, and the long nozzle support fixes and lifts the long nozzle to complete the protection casting work of the ladle. A steel ladle is arranged above the long nozzle trunnion ring, a nozzle filled with high-temperature molten steel is arranged inside the long nozzle trunnion ring, and a tundish molten steel impact area is arranged below the long nozzle trunnion ring. The temperature of the nozzle supporting ring which is continuously positioned in a high-temperature area reaches more than 800 ℃, and meanwhile, the manipulator continuously provides an upward jacking force for the supporting ring, so that the nozzle supporting ring can deform after a period of use and cannot flexibly rotate in the support to cause the deflection of the long nozzle, and the sealing is not tight on the joint surface of the ladle and the long nozzle, so that the air suction is caused, and the casting protection effect is seriously influenced. In this case, a new trunnion ring must be replaced to ensure the quality of molten steel. The anti-drop stop iron is welded at the position of the trunnion of the long nozzle, so that the old trunnion ring can be removed after the stop iron at the position of two trunnions is cut off when the trunnion is replaced, then a new trunnion ring can be installed, and meanwhile, the anti-drop stop iron must be welded again to prevent the trunnion from dropping when the nozzle is replaced. These operations, when completed during pouring, require a time of about 20 minutes, which on the one hand results in an unprotected pouring of the ladle in a 20 minute time period and on the other hand increases the risk of injury to the operator due to the exposure of the manipulator position to a high temperature environment as a result of the open pouring of the steel stream.
Disclosure of Invention
An object of the utility model is to provide a but long mouth of a river manipulator support of quick replacement trunnion ring, it is convenient, safe to change the trunnion ring, improves work efficiency.
Realize the utility model discloses a but long mouth of a river manipulator support of quick replacement trunnion ring, including the support body, the support body is that two bear the arm about U font has, bears on the arm on a left side and is setting up a trunnion ring gudgeon pole hole, bears on the arm upper portion on the right side and is setting up one towards support body back open-ended U font slope slide, and during the use, one side gudgeon of trunnion ring slides to slope slide bottom, the opposite side gudgeon of trunnion ring insert the trunnion ring gudgeon pole hole in.
The utility model discloses unique trunnion ring gudgeon pole hole and slide design can make things convenient for the trunnion ring to accomplish fast and dismantle and the installation to the arbitrary angle of manipulator rotation can not cause the trunnion ring to break away from the support, has eliminated in the production process because the interim production and the casting blank quality influence that the mouth of a river trunnion ring consumes the time length to cause. After improvement, the support structure of the backing ring is strengthened, the high-temperature structural stability is enhanced, the deformation is not easy, the service life is greatly prolonged, the replacement frequency is greatly reduced, the cost is reduced by more than 50 percent before improvement, and the production cost is saved. The support ring and the bracket structure have small fit clearance, and the long nozzle and the ladle nozzle can be tightly combined in the use process, so that the secondary oxidation of molten steel is reduced, and the product quality is ensured. The service life of the supporting ring bracket and the supporting ring is prolonged, the replacement workload is reduced, and the working environment of workers is greatly improved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic perspective view of the present invention.
Detailed Description
The utility model provides a but long mouth of a river manipulator support of quick replacement trunnion ring, as shown in figure 1, includes support body 6, and support body 6 is two about U font has bears arm 1, 4, bears the arm 1 on the left side and is setting up a trunnion ring gudgeon arm bore 2, bears arm 4 upper portion on the right side and is setting up one towards support body back open-ended U font slope slide 5, during the use, one side gudgeon of trunnion ring 3 slides to slope slide bottom, the opposite side gudgeon of trunnion ring 3 inserts trunnion ring gudgeon arm bore 2 in.
