Description

Technical Field

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

[0002] The iron ladle is widely used in casting operations in the foundry industry. After receiving the molten iron in front of the furnace, it is transported to the casting mold by a crane for pouring. The body of the existing iron ladle is built with refractory bricks, and in order to facilitate the pouring of molten iron, a spout is designed on the top of the iron ladle. After the wall bricks are built, the mold is supported on the wall bricks, and the casting material is only knotted at the spout to form the spout casting material. The joint area between the top wall bricks and the spout casting material of the iron ladle with this structure is prone to grooves and iron leakage, resulting in the problem of shortening the life of the iron ladle.

[0003] In order to solve the above technical problems, the inventor filed a Chinese utility model patent application with application number CN202022802232.2 on November 27, 2020, entitled A Long-life Ladle, which has a steel shell, a spout extending outward formed on the top of the steel shell, and refractory bricks built on the inner wall and bottom of the steel shell. The upper surface of the refractory bricks at the inner wall of the steel shell is lower than the position of the spout, and a casting material with the same thickness as the refractory bricks is integrally formed at the top of the inner wall of the steel shell and the inner wall of the spout. This solution changes the spout and the wall bricks at the inner wall of the ladle at the same height as the spout into a casting structure, which can solve the problem of abnormal erosion at the joint. However, after a period of use, there are also certain problems. The main problem is that since the top of the inner wall of the steel shell is a casting structure, when it is eroded and needs to be repaired, the casting needs to be disassembled, and since the casting part is reinforced with anchor nails welded on the steel shell, it is difficult to remove the casting, which affects the efficiency of construction. In addition, the bottom bricks of the existing ladle are also prone to erosion after long-term use, and the staff cannot accurately judge the erosion depth of the bottom bricks based on visual inspection, resulting in the bottom bricks not being fully utilized or the bottom bricks being severely eroded and causing safety accidents; and the junction between the wall bricks and the bottom bricks of the existing ladle is also prone to damage, resulting in a reduction in the overall service life of the ladle. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a novel molten iron ladle, which has a reasonable design structure and is easy to use. Anchor nails that can be detachably connected to the steel shell are used to reinforce the castable above the inner wall of the steel shell. On the one hand, the problem of abnormal erosion of the castable at the mouth of the ladle and the joint between the traditional wall bricks is avoided. On the other hand, when repairing the molten iron ladle, the castable part can be quickly removed to improve the construction efficiency.

[0005] The technical solution adopted by the utility model is: a novel molten iron ladle, comprising a steel shell, wherein the middle position of the inner wall of the steel shell is built with wall bricks, the inner wall of the steel shell and the position above the wall bricks is provided with a spout castable with the same thickness as the wall bricks, and the spout castable is reinforced by anchor nails detachably installed inside the steel shell.

[0006] A plurality of conical holes are evenly arranged on the upper side wall of the steel shell. The anchor nail comprises a conical section matching the conical hole. A threaded hole is arranged at the end of the conical section. The anchor nail is installed in the steel shell by bolts.

[0007] The top of the ladle is provided with a ladle spout inclined outwards, and the height of the ladle spout is consistent with the height of the ladle spout castable.

[0008] The invention also includes bottom bricks located at the bottom of the steel shell, and a plurality of prefabricated blocks evenly distributed around the center of the steel ladle are installed in the circumferential area where the bottom bricks and the wall bricks meet.

[0009] The prefabricated block comprises a backrest with the same thickness as the wall-cladding bricks, a base with the same thickness as the bottom-cladding bricks, and a slope protection arranged between the backrest and the base.

[0010] A warning block is pre-buried below the ladle bottom brick and at the center of the ladle.

[0011] The beneficial effects of the utility model are:

[0012] The utility model has a reasonable design structure and is easy to use. Anchor nails that can be detachably connected to the steel shell are used to reinforce the castable above the inner wall of the steel shell.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-2 As shown, a new type of molten iron ladle includes a steel shell 1, a wall brick 5 is built in the middle of the inner wall of the steel shell 1, and a spout castable 2 with the same thickness as the wall brick 5 is provided on the inner wall of the steel shell 1 and above the wall brick 5. The spout castable 2 is reinforced by an anchor nail 4 detachably installed inside the steel shell 1.

[0018] Specifically, a plurality of tapered holes 10 are evenly provided on the upper side wall of the steel shell 1, the anchor nail 4 includes a tapered section 401 matching the tapered hole 10, a threaded hole is provided at the end of the tapered section 401, and the anchor nail 4 is installed in the steel shell 1 by means of a bolt 9. When anchoring, the tapered section 401 is inserted into the tapered hole 10 on the side wall of the steel shell 1 from the inside of the steel shell 1, and is connected to the threaded hole in the center of the tapered section 401 by means of an external bolt 9. The tighter the bolt 9 is, the more firmly the anchor nail 4 is fixed. The purpose of such a setting is, on the one hand, to realize the installation of the anchor nail 4, and on the other hand, the tapered section 401 on the anchor nail 4 can be used to achieve close contact with the tapered hole 10 on the side wall of the steel shell 1 to avoid gaps and achieve better sealing. When removing the nozzle castable 2, the bolt 9 can be removed, and the anchor nail 4 can be knocked toward the center of the steel shell 1 to quickly remove the nozzle castable 2.

[0019] The top of the ladle has a spout 3 inclined outward, and the height of the spout 3 is consistent with the height of the spout castable 2. For traditional refractory bricks, since refractory bricks cannot be laid at the spout 3, the wall bricks 5 on the top of the traditional steel shell 1 cannot be laid in a ring. When the ladle is working, the refractory bricks expand due to heat. Under unsupported conditions, the refractory bricks are very likely to fall off. To avoid this problem, the original refractory bricks on the top of the ladle are replaced with castables and are integrally formed with the castables on the inner wall of the spout 3. Firstly, the problems of grooving and iron leakage between the refractory bricks and the castables of the spout 3 can be avoided, and secondly, the falling off of refractory bricks can be avoided, thereby extending the service life of the ladle.

[0020] The steel shell also includes a bottom brick 6 located at the bottom of the steel shell 1. In the circumferential area where the bottom brick 6 and the wall brick 5 meet, a number of prefabricated blocks 7 evenly distributed around the center of the steel ladle are installed.

[0021] The prefabricated block 7 has a backrest 701 with the same thickness as the wall bricks 5, a base 703 with the same thickness as the bottom bricks 6, and a slope protection 702 arranged between the backrest and the base 703. When molten steel is poured into the ladle, the slope protection 702 structure integrally formed on the prefabricated block 7 can reduce the probability of damage to the area, and can increase the strength of the ladle lining formed by the wall bricks 5, the bottom bricks 6 and the prefabricated block 7 therebetween, improve the impact resistance of the ladle lining structure, and extend the service life.

[0022] A warning block 8 is embedded below the bottom brick 6 and at the center of the ladle. The color of the warning block 8 can be different from the color of the bottom brick 6. When the bottom brick 6 is eroded, the staff can check whether the warning block 8 is exposed, thereby facilitating the staff to determine whether to remove and repair the bottom brick 6.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
