Problems solved by technology

[0004] 1. The final movement track of the iron ladle cover is from bottom to top, and slagging will occur along the edge of the ladle. If the height of slagging exceeds the safety distance reserved during design, it will cause the iron ladle cover to be unable to perform the capping action;
[0005] 2. The hinge points of each connecting rod and the iron-clad car are scattered, the size is not easy to control and it is difficult to disassemble;
[0006] 3. The connecting rod and the iron cover are fixedly connected to form a whole. Although the rigidity is good, the cover does not have any independent action, so the adaptability is poor
Problems in this scheme: the use conditions are limited, and the system must be able to use elongated iron-clad cars. The length of ordinary iron-clad cars is limited, and long tracks cannot be added without limit. If the track is not long enough, it cannot be realized. uncovering action

Embodiment 1

[0033] Such as figure 1 , figure 2 A ladle uncovering device shown is provided with a capping mechanism on both sides of the ladle 4 on the iron ladle car 5, and the capping mechanism includes a semicircular ladle cap 1, an active rocker 2, a connecting rod 3. Oil cylinder 6 and base 7. The two upper ends of the active rocker 2 are hinged to the semicircular iron cover 1, the lower legs are hinged to the base 7, and an oil cylinder 6 is hinged to the inside of the two legs; the other end of the oil cylinder 6 is hinged to the base 7; The two ends of the connecting rod 3 are hinged with the base 7 and the semicircular iron clad cover 1 respectively.

[0034] The hinged hole of the semicircular iron ladle cover 1 and the connecting rod 3 is a waist-shaped hole in the vertical direction. When there is slagging along the mouth of the molten iron ladle 4, the semicircular iron ladle cover 1 in the closed state can be moved along the The waist-shaped hole moves up and down, and...

Embodiment 2

[0038] Such as figure 1 , figure 2 , image 3 , Figure 4 Shown, a kind of molten iron ladle adds and uncovers the capping method of capping device among the present invention, and step is as follows:

[0039] When the iron-clad car 5 with the cover moves to the iron-connecting nozzle station, start the ladle adding and uncovering device, and open the semicircular iron-ladle cover 1 to both sides at the same time;

[0040] When the cover is uncovered, the active rocker 2 is driven by the oil cylinder 6 to rotate, and then the active rocker 2 drives the semicircular iron cover 1 to move, and the semicircular iron cover 1 drives the connecting rod 3 to rotate. The iron ladle cover 1 moves to both sides respectively, and becomes an open state, after which, the operation of connecting molten iron or hanging ladle can be carried out;

[0041] After receiving the molten iron, start the ladle adding and uncovering device again, and cover the semicircular iron ladle cover 1 from...

Embodiment 3

[0045] combine Figure 5 And the method for adding and uncovering the ladle adding and uncovering device in the above-mentioned embodiment 2, it can be seen that the final trajectory of the iron ladle cover in the prior art scheme one is from bottom to top, and the iron ladle lid movement track in the prior art scheme two It is a horizontal movement, and the movement track of the last section of the capping device in the present invention is that the last section of the track is a crimping movement from top to bottom. By simulating design and optimizing the length and positional relationship of the connecting rod mechanism, it can be ensured that the movement track of the ladle cover in the present invention meets the expected effect, and can better adapt to slagging at the mouth of the ladle.

Abstract

The invention discloses a ladle capping and uncapping device. Capping and uncapping mechanisms are arranged on the two sides of a ladle on a ladle vehicle. Each capping and uncapping mechanism comprises a semicircular ladle cap, driving rocking bars, a connecting rod, oil cylinders and a base, wherein two support rods at the upper ends of the driving rocking bars are hinged to the semicircular ladle cap, and two legs at the lower ends of the driving rocking bars are hinged to the base; one oil cylinder is hinged to the inner side of each leg, and the other ends of the oil cylinders are hingedto the base; the two ends of the connecting rod are hinged to the base and the semicircular ladle cap correspondingly. The ladle capping and uncapping device is convenient to install, high in practicality, free of weather influence and higher in safety.

Description

technical field [0001] The invention relates to the field of metallurgical industry production, in particular to a device for adding and uncovering a molten iron ladle. Background technique [0002] Most domestic iron and steel enterprises generally use open ladles to contain molten iron, and the ladles are placed on ladle cars and transported from blast furnaces to steelmaking work areas by diesel locomotives. At present, the blast furnaces in domestic iron and steel enterprises are far away from the steelmaking operation area, usually up to several kilometers, and the distance is open-air, and the transportation and waiting time are long. In addition, the molten iron ladle is exposed, and the molten iron is directly in contact with the air. , The temperature difference between the molten iron and the ladle and the air is large, heat exchange occurs continuously, and a large amount of heat is emitted, increasing energy consumption and affecting the life of the iron ladle li...
