Description

Technical Field

[0001] The utility model belongs to the technical field of molten iron ladles, in particular to a durable molten iron ladle. Background Art

[0002] The hot metal ladle is used for casting in the foundry. It is used as an intermediate ladle to receive the molten iron in front of the submerged arc furnace. After the slag and gold are separated, the molten iron is put into the ground mold to obtain a large piece of chromium-iron alloy. The hot metal ladle is then transported to the maintenance workshop to clean and repair the hot metal slag and lining in the ladle. The cleaned hot metal slag is added to the submerged arc furnace as a return material due to its high chromium content. The repaired hot metal ladle is transported by a crane to the submerged arc furnace chute for casting again.

[0003] The temperature of molten iron is high and the storage capacity of the ladle is large. Each time the molten iron is filled, the ladle will always be deformed, especially at the molten iron outlet. Therefore, the ladle needs to be replaced, maintained and repaired after each molten iron pouring, which causes high economic costs for the factory. Utility Model Content

[0006] The outer peripheral surface of the enclosure is horizontally connected with U-shaped channel steels at intervals, and H-shaped steels are evenly spaced between adjacent U-shaped channel steels. The openings at both ends of the H-shaped steels are respectively connected to the U-shaped channel steels, and the H-shaped side of the H-shaped steels fits the outer wall of the enclosure;

[0007] A notch is arranged in the center of the top of one side wall of the ladle, and a detachable drainage nozzle is connected to the corresponding notch, and an iron outlet is arranged at the bottom of the other side wall of the ladle;

[0008] The two ends of the top U-shaped channel steel of the two side walls of the package body adjacent to the side wall where the drainage nozzle is located are symmetrically connected with lifting ears, and the bottom of the lifting ears is clamped with the U-shaped channel steel.

[0018] The utility model will be further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, the durable iron ladle comprises a ladle body 1, the inner wall of the ladle body 1 is provided with a heat insulating lining 2 to isolate the high temperature damage of the ladle body 1 from the high temperature molten iron;

[0020] U-shaped channel steels 4 are connected horizontally and spaced apart on the outer peripheral surface of the package body 1, and H-shaped steels 5 are evenly spaced apart between adjacent U-shaped channel steels 4. The openings at both ends of the H-shaped steels 5 are respectively connected to the U-shaped channel steels 4, and the H-shaped side of the H-shaped steels 5 fits the outer wall of the package body 1. The structure of the package body 1 is strengthened by the cooperation of the U-shaped channel steels 4 and the H-shaped steels 5, so that the overall bearing capacity of the package body 1 is increased and deformation is not easily caused;

[0021] A notch 11 is provided in the center of the top of one side wall of the ladle 1, and a detachable drainage nozzle is connected to the corresponding notch 11, which is convenient for disassembly, replacement and maintenance. An iron outlet 13 is provided at the bottom of the other side wall of the ladle, and the iron outlet 13 and the notch 11 are not on the same side wall; the drainage nozzle corresponding to the notch 11 is used to overflow molten iron to other ladles or discharge molten iron slag, and the iron outlet 13 is used to put the molten iron in the ladle into the ground mold. Under normal conditions, the iron outlet 13 will be blocked, and the iron outlet 13 will be opened only when pouring is required.

[0022] The two ends of the top U-shaped channel steel 4 of the two side walls of the package body 1 adjacent to the side wall where the drainage nozzle is located are symmetrically connected with the lifting ears 3, and the bottom of the lifting ear 3 is clamped with the U-shaped channel steel 4 to ensure the connection stability of the lifting ear 3.

[0023] In order to ensure the fixing effect of the drainage nozzle, the drainage nozzle further includes a nozzle body 12, and fixing plates 6 are connected to both sides of the nozzle body 12. The fixing plates 6 are connected and fixed to the package body 1 through bolts 7.

[0024] In order to further enhance the supporting effect of the mouth body 12 , U-shaped frames 9 are provided on both sides of the notch 11 on the bag body 1 , and a hanging frame 10 matching the U-shaped frame 9 is provided on the mouth body 12 .

[0025] Furthermore, a limiting strip 8 is provided at the bottom of the nozzle body 12 and is slidably engaged with the upper wall of the U-shaped channel steel 4 to enhance the fixing effect of the nozzle body 12 .

[0026] In order to achieve a good fixing effect of the U-shaped channel steel 4, the U-shaped channel steels 4 on the adjacent side walls of the package 1 are staggered and can more effectively cover the outer wall of the package 1 to form reinforcement and avoid deformation.

[0027] When the utility model is used specifically: the installation of the nozzle body 12 is carried out through one side of the package body 1, firstly, the limit formed by the limit strip 8 is slidably installed in alignment with the U-shaped channel steel 4, then the hanger 10 is pushed to form a connection with the U-shaped frame 9, and the nozzle body 12 is aligned with the notch 11, and finally the fixing plate 6 is fixed by the bolt 7 to complete the installation of the nozzle body 12;

[0028] When the ladle 1 is filled with molten iron, the insulating lining 2 can reduce the damage to the ladle 1 caused by the high temperature of the molten iron. The U-shaped channel steel 4 and the H-shaped steel 5 can maintain the structural stability of the ladle 1. The drainage nozzle, which is most easily deformed, can be disassembled and replaced according to usage requirements, thereby improving maintenance efficiency and effectively extending the service life of the ladle 1.
