Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, in particular to a ladle car for metallurgy. Background Art

[0002] In the metallurgical industry, ladle cars are widely used as important tools. A ladle car is an electric flat car used to transport ladles in a steel mill, and its power is provided by a motor, usually a high-temperature explosion-proof motor. During the operation of the steel mill, the working environment of the ladle car is relatively harsh. During the steelmaking process, the molten steel has a high temperature and strong fluidity, and it is easy to splash, resulting in a large amount of steel slag accumulating around the ladle car. At the same time, there will also be steel slag randomly falling from positions such as the tapping hole and the flue. If a large amount of high-temperature steel slag accumulates above the machine cover, it will not only cause a relatively high temperature in the transmission room below the machine cover, and the motor seals are prone to aging and oil leakage, but also problems such as the slag pot not being placed in place or unevenly placed will occur, and it is necessary to regularly clean the steel slag above the machine cover; the splashing and accumulation of slag increase the difficulty and cost of cleaning work to a certain extent. During transportation, due to the large weight and high center of gravity of the ladle, it is easy to tilt, affecting the stability and safety of the ladle. After the ladle dumps the slag, it cannot return to the correct position, and when it sits on the ladle car, the ladle body will tilt, affecting the tapping operation and the continuous casting process, causing erosion and damage to the refractories of the ladle and the tundish. If the ladle dumps the slag and then falls to the ground for adjustment, it will occupy the process time and increase the operating steps of the overhead crane, which is rather inconvenient. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a ladle car for metallurgy, which can effectively reduce the accumulation of steel slag, simplify the cleaning of steel slag, and at the same time can adjust the position of the ladle to avoid wasting time by frequently using the overhead crane to lift and adjust the ladle.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a ladle car for metallurgy, including a bottomless rectangular frame main body. The front and back of the frame main body are two load-bearing beams, and the left and right are two installation beams. There are bearing ears for installing the ladle on the load-bearing beams. Motor casings are arranged on both sides of the frame main body. Below the casings are wheel frames driven by motors. Above one side casing of the frame main body, there are two triangular slag-draining plates arranged opposite to each other. On the outer side above the other side casing of the frame main body, there is a slag pot mounting rack for placing the slag pot, and on the inner side, there is an inclined slag-draining plate with a lower outer side and a higher inner side.

[0005] A further improvement of the technical solution of the utility model lies in that the bottom edge of each slag-draining plate is hinged to the top of the casing, and a turning telescopic rod is arranged between the slag-draining plate and the top of the casing for turning the slag-draining plate outwards by means of expansion and contraction.

[0006] A further improvement of the technical solution of the utility model lies in that the surface of the slag-draining plate is provided with a high-temperature resistant coating.

[0007] A further improvement of the technical solution of the present utility model lies in that: an adjusting telescopic rod pointing to the ladle is arranged below the outer surface of the installation beam, which is used to adjust the position of the bottom of the non-returned ladle by means of telescoping.

[0008] A further improvement of the technical solution of the present utility model lies in that: a high-temperature resistant contact head in direct contact with the ladle is arranged at the top of the adjusting telescopic rod.

[0009] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model is as follows: by arranging two slag-draining plates placed in a triangular shape above the chassis without a slag pot installed, the upper part of the chassis is no longer a flat surface where steel slag is likely to accumulate. Under the action of gravity, the steel slag will slide down along the slag-draining plates to the slag channel below, effectively reducing the accumulation of steel slag above the chassis. By arranging an inclined slag-draining plate with a lower outer part and a higher inner part above the chassis with a slag pot installed, it can be fully coordinated with the slag pot, and the steel slag falling outside the slag pot will also slide along the slag-draining plate to the slag channel, without accumulating steel slag outside the slag pot. At the same time, in order to better clean the steel slag, each slag-draining plate is hinged to the top of the chassis, and a flipping telescopic rod is arranged in each slag-draining plate. During the process of the telescopic rod extending, it can drive the slag-draining plate to flip outwards and unload the adhered steel slag, saving time and effort. By arranging adjusting telescopic rods pointing to the ladle on the installation beams on both sides of the ladle, the head of the telescopic rod abuts against the bottom of the ladle. When the ladle is not in the correct position after returning, the telescopic rods on both sides can be used to touch the ladle through telescoping for return adjustment. Description of the Drawings

[0013] The following further describes the present utility model in detail with reference to the embodiments:

[0014] As Figure 1As shown in the figure, it is a structural schematic diagram of a ladle car for metallurgy. The main body is a rectangular frame formed by a load-bearing beam 1 and a mounting beam 3. The front and back of the rectangular frame main body are two load-bearing beams 1, and the left and right are two mounting beams 2. There are bearing ears on the load-bearing beam 1. The frame main body has no bottom. When installing the ladle 5, it is hoisted and fixed to the bearing ears on both sides by a crane. The ladle 5 is supported in the air by the load-bearing beam 3. Motor casings are provided on both sides of the frame main body. There is a motor inside the casing, and wheels driven by the motor are provided below the casing. The ladle car is rotated by the wheels to transport the ladle. In this embodiment, above the casing on the left side of the frame main body, there are two slag-draining plates 4 arranged in a triangular shape with the outside lower and the inside higher. The surface of the slag-draining plate 4 is provided with a high-temperature resistant coating, which can also increase the smoothness. This triangular pointed-top structure is not easy to accumulate steel slag, and the steel slag will slide along the slag-draining plate 4 to both sides and fall into the slag channel at the bottom. The steel slag accumulation on the casing surface will be greatly reduced. There is a hinge between the bottom of the two slag-draining plates 4 on the left casing and the top of the casing, and the connection method is hinged, that is, the slag-draining plate 4 can be flipped with the bottom edge as the axis. There are flipping telescopic rods 41 between the two slag-draining plates 4 and the top of the left casing, that is, there are two flipping telescopic rods 41 inside the triangular space. The bottom of the telescopic rod is arranged on the casing, and the top of the telescopic end is fixedly connected to the middle of the slag-draining plate 4. When the telescopic rod extends upward, with the assistance of the hinge, the slag-draining plate 4 will flip outward. When flipping outward, under the action of gravity, the steel slag scattered on the surface of the slag-draining plate 4 will slide down into the slag channel under the bottomless frame, saving time and effort in cleaning the steel slag. On the outer side of the casing on the right side of the frame main body, there are symmetric slag pot mounting brackets 3 for installing slag pots to collect the steel slag at the tapping hole. There is a slag-draining plate 4 matching the slag pot arranged on the inner side of the top of the casing. This slag-draining plate 4 is arranged with the outside lower and the inside higher in an inclined manner. The steel slag that does not fall into the slag pot will also slide along this slag-draining plate 4 into the slag channel. Similarly, there is a hinge at the bottom of this slag-draining plate 4, which is hinged to the top of the casing, and there is a flipping telescopic rod 41 between the slag-draining plate 4 and the top of the casing.

[0015] Below the outer surface of the mounting beam 2 on both sides of the ladle 5, there are adjusting telescopic rods 21 pointing to the ladle 5. The top of the adjusting telescopic rod 21 is provided with a high-temperature resistant contact directly contacting the ladle 5, and the contact can directly push against the lower part of the ladle through telescoping. When the ladle 5 is tilted after pouring the steel slag and cannot return to the correct position and the tapping position is inclined, the adjusting telescopic rods 21 on both sides can be controlled. By extending the telescopic rods, the contact touches the lower part of the ladle to adjust the position and help the ladle return to the correct position, preferably avoiding the waste of time in frequently using the crane to lift and adjust the ladle, and solving the problem that the incorrect position of the ladle affects the service life of the refractories of the ladle and the tundish.

[0016] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
