Problems solved by technology

[0003] At present, domestic and foreign oxygen lances are mostly repaired horizontally, which occupies a large area. In addition, because the oxygen lance is more than 20 meters long, the horizontal repair is easy to deform, and the oxygen lance is scrapped.
Overseas also use remote control crane control, space suspension of oxygen lance, and vertical repair of oxygen lance. In China, only Baosteel adopts this method, but it is only used to replace the tip of the gun, and the outer tube and middle tube cannot be replaced. In addition, this device requires High-altitude workshops and remote-controlled cranes require huge investment, which is difficult for general steelmaking plants to realize

Embodiment Construction

[0017] Figure 1, figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 As shown, the oxygen lance repair device consists of lower platform 1, repair room 2, slag cleaning room 3, escalator 4, lifting platform 5, upper platform 6, electro-hydraulic push rod driven trolley 7, lifting electric hoist 8, lifting I-beam 9. It is composed of walking electric hoist 10 and walking I-shaped steel beam 11. The lower platform 1 and the upper platform 6 are welded steel structures, and the four corners are connected with workshop columns. The lower platform 1 is installed with the repair room 2 and the slag cleaning room 3, and the upper platform 6 is equipped with 6 electro-hydraulic push rod-driven trolleys 7, and the oxygen lance repair personnel can test the repaired oxygen lance on the upper platform 6. The escalator 4 is welded by steel structure, the top is connected with the upper platform 6, and the bottom is connected with the lower platform 1. The oxygen lance repair perso...

Abstract

An apparatus for repairing oxygen gun is composed of upper and lower platforms, stair way between two platforms, repair room and slag removing room on lower platform, the lifter of oxygen gun in the repair room, electric hydraulic carriage on upper platform for moving oxygen gun horizontally, and two electric hoists fixed to top beam for moving oxygen gun in vertical and horizontal directions. Its advantages are less investment, less possessed ground area, and no deforming of oxygen gun.

Description

Technical field [0001] The invention relates to a repair device for a steel-making converter oxygen lance, which is particularly suitable for repairing a steel-making converter oxygen lance. Background technique [0002] The oxygen lance is an important part of the oxygen blowing device of the steelmaking converter. When the converter is blowing oxygen, the oxygen lance is inserted by the lifting device at an appropriate height above the metal liquid level in the furnace to blow oxygen into the molten metal pool for steelmaking. When the blowing is stopped, the lifting device lifts the oxygen lance to a certain height, waiting for the lance to continue blowing. When the gun head is working, it is close to the highest temperature zone in the furnace, and the working conditions are very bad. Therefore, the gun tip and the outer tube and the front of the intermediate tube need to be replaced regularly. [0003] At present, domestic and foreign oxygen lances are mostly repaire...
