Description

Technical Field

[0001] The utility model relates to the field of steel smelting, in particular to a tool for processing nodules at the mouth of a steel ladle. Background Art

[0002] During the process of steel tapping and argon blowing, the ladle edge will inevitably be adhered to the mixture of steel and slag, thus forming nodules at the ladle mouth. Nodules at the ladle mouth will have adverse effects on steelmaking production:

[0003] 1. The nodules on the ladle edge make it difficult to pour out the ladle slag. The slag will solidify at the bottom of the ladle, affecting the air permeability of the ladle air brick and the smoothness of the drain;

[0004] 2. Too many nodules form on the edge of the bag, which can easily fall off during lifting and cause safety accidents.

[0005] The current method for dealing with nodules on the ladle mouth is to place the ladle at a specific ladle position and use a furnace dismantling car to break up the nodules on the ladle mouth by vibration. This method is time-consuming, inconvenient and difficult to handle. Utility Model Content

[0006] The utility model aims to provide a tool for processing nodules at the mouth of a steel ladle.

[0007] The technical solution to achieve the purpose of the utility model is: a tool for treating nodules at the mouth of a steel ladle, comprising a base, two side panels are vertically installed on the upper surface of the base, the two side panels are arranged opposite to each other, a rectangular back panel is installed between the two side panels, the back panel is located in the middle of the two side panels, the back panel has a back panel front and a back panel, the cross-sectional shape of the part of the side panel that exceeds the back panel back and the front of the back panel is a right-angled trapezoid, the upper end surface of the part of the side panel that exceeds the front of the back panel is a first inclined surface, and the first inclined surface is inclined downward from the upper end surface of the back panel; the upper end surface of the part of the side panel that exceeds the back of the back panel is a second inclined surface, and the second inclined surface is inclined downward from the middle of the back of the back panel.

[0008] Furthermore, the back panel and the side panels are an integrally formed structure.

[0009] The tooling for processing nodules at the mouth of a ladle realized by the utility model is installed on the ground. When the mouth of the ladle is opposite to the tooling for processing nodules at the mouth of the ladle, the ladle continuously descends, and the nodule portion at the mouth of the ladle collides with the upper end surface of the back plate. The sharp portion formed by the back plate and the first inclined surface lifts up the nodule at the mouth of the ladle until the nodule at the mouth of the ladle falls off. This structure can effectively reduce the processing time of the nodule at the mouth of the ladle and the problem of difficulty in processing the nodule at the mouth of the ladle, and has a long service life.

[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown, a tool for treating nodules at the mouth of a steel ladle comprises a base 1, and two side panels 2 are vertically mounted on the upper surface 11 of the base 1, and the two side panels 2 are arranged opposite to each other, and a rectangular back panel 3 is mounted between the two side panels 2, and the back panel 3 is located in the middle of the two side panels 2, and the back panel 3 has a back panel front 31 and a back panel back 32, and the cross-sectional shapes of the parts of the side panels 2 exceeding the back panel back 32 and the front panel front 31 are both right-angled trapezoidal, and the upper end surface of the part of the side panel 2 exceeding the front panel front 31 is a first inclined surface 21, and the first inclined surface 21 is inclined downward from the upper end surface 33 of the back panel 3; the upper end surface of the part of the side panel 2 exceeding the back panel back 32 is a second inclined surface 22, and the second inclined surface 22 is inclined downward from the middle part of the back panel back 32.

[0015] After the ladle mouth is nodulated, the ladle is hoisted in a flat position by a crane to the top of the ladle mouth nodule treatment tooling. Figure 3 As shown, the sharp part formed by the back plate 3 and the first inclined surface 21 is aligned with the mouth of the ladle 100. The ladle continues to descend and presses the nodule 200 on the sharp part. The reaction force of the sharp part is used to lift the nodule until it falls off. Since the nodule and the ladle refractory are not made of the same material and are in a high temperature state (1400°C), they are easy to fall off as long as there is force. This structure can effectively reduce the processing time and difficulty of nodule processing, and has a long service life.

[0016] The back plate and the side plate of the utility model can be an integrally formed structure formed by cutting the channel steel forward and backward. If the ladle mouth nodule treatment tool has only one back plate, it is easy to bend. The second inclined surface of the side plate and the part of the side plate that exceeds the back of the back plate form a special right-angle trapezoidal structure, which ensures that the back plate is not easy to bend when subjected to force and ensures that the back plate is well subjected to force. The back plate and the side plates can also be processed separately and then welded and fixed.

[0017] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
