Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for iron and steel smelting, specifically to a slag pushing device for converter slag carts. Background Technology

[0002] The converter steelmaking process generates a large amount of converter slag. If not cleaned up in a timely manner, this slag will cause pollution and harm to the environment. Cleaning up converter slag helps reduce the pollution of soil, water sources, and air by these harmful substances, protecting environmental quality. At the same time, converter slag contains certain recyclable resources, such as iron and calcium. Through cleaning and sorting, these resources can be recycled, reducing production costs and improving resource utilization efficiency. Accumulated converter slag also poses safety hazards, such as clogging the furnace opening and affecting the normal operation of equipment. Timely cleaning of converter slag ensures smooth and safe production. Rails are laid under the converter for steel ladle cars and slag ladle cars. During steelmaking, slag adhering to the furnace opening, dust hood, and oxygen lance generated by converter splashing falls onto the rails under the furnace. If this slag accumulates to a thickness higher than the rail level on both sides, or if hard slag falls onto the rails, it can easily cause steel ladle cars and slag ladle cars to jam or derail, leading to production interruptions.

[0003] The application of a converter slag car pushing device can effectively push and clean converter slag, prevent slag overflow and accumulation, and ensure the smooth operation of the slag car. There are already improvements and optimizations to converter slag car pushing devices in the existing technology, such as the patent application number 202021578062.8 and publication number CN213295411U. The basic principle of this patent for a slag car pushing device is as follows: it includes a slag car wheel assembly, a pushing bottom plate, and a pushing plate. A hinge device is provided at the front end of the slag car wheel assembly, and the front end of the slag car wheel assembly is fixedly connected to the pushing bottom plate through the hinge device. The pushing bottom plate is threadedly connected to the pushing plate with bolts. Two notches are opened at the bottom of the pushing plate, and a through-hole is opened inside the pushing plate. A through groove is opened inside the pushing bottom plate, and bolts pass through the through-hole and through groove in sequence. By setting up a slag-pushing bottom plate and a slag-pushing plate, when the slag accumulation is too thick and the slag tanker truck lacks power, the total length of the slag-pushing plate and the slag-pushing bottom plate can be adjusted to adjust the height of the slag-pushing plate, thereby reducing the resistance of slag pushing. The slag-pushing plate is fastened with bolts, and when the slag-pushing plate is deformed or damaged, the bolts can be removed and replaced.

[0004] However, the converter slag car pushing device in the above-mentioned patent has certain drawbacks and shortcomings: as the converter slag car moves forward, the converter slag in the slag pit continuously accumulates on the pushing bottom plate and pushing plate under the pushing of the slag. At the same time, the converter slag will also continuously overflow onto the slag car tracks on both sides. Some converter slag will remain on the tracks. Manual cleaning is time-consuming and labor-intensive and cannot completely solve the problem. Over time, the high-temperature molten slag will damage the converter slag car tracks, affect the normal operation of the converter slag car, increase maintenance work, and make the shutdown maintenance time longer. Utility Model Content

[0005] The purpose of this utility model is to provide a slag pushing device for converter slag cars, so as to solve the problem that slag will remain on the track during the slag pushing process of the converter slag car in the above-mentioned patent.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a slag pushing device for a converter slag car, including a fixed base, a hinged component fixedly connected to the fixed base, a slag pushing plate one hinged to the hinged component, the free end of the slag pushing plate one overlapping two tracks, the fixed base being fixedly connected to the converter slag car, a slag pushing plate two hinged to the slag pushing plate one, the slag pushing plate two being located between the two tracks, and a slag pushing plate three being pin-connected to both sides of the slag pushing plate one, the free end of the slag pushing plate three overlapping the tracks.

[0007] The principle and beneficial effects of this utility model are as follows: By setting up slag pusher plate one, slag pusher plate two, and slag pusher plate three, as the converter slag car moves forward, slag pusher plate one, slag pusher plate two, and slag pusher plate three move forward with the converter slag car and push slag. Slag pusher plate one continuously pushes forward the slag accumulated at the top of the track, slag pusher plate two continuously pushes forward the slag in the slag pit, and the slag pusher plate three is located in front of the slag pusher plate one. As slag pusher plate three continuously pushes forward, it pushes the slag accumulated on the track surface to both sides to prevent slag from remaining on the track during the slag pushing process.

[0008] By setting up a slag pusher plate 1, the free end of which rests on the track to clean the slag accumulated at the top of the track. The slag pusher plate 2 is located between the two tracks to clean the slag in the slag pit. The free ends of the two slag pusher plates 3 rest on the two tracks respectively and are located in front of the slag pusher plate 1. As the converter slag car moves forward, the slag in the slag pit will gradually accumulate on the slag pusher plate 1 and the slag pusher plate 2. After accumulating to a certain extent, it will overflow the track range. At this time, the slag pusher plate 3 will push the slag that has overflowed onto the track to both sides, making it easier to clean the slag on the track.

[0009] Option 2, a preferred option of the basic scheme, includes a slotted lug, a connecting pin, and a lug seat. The slotted lug is fixed to the fixed seat, and the lug seat is fixed to the slag pusher plate. The slotted lug and the lug seat are hinged together by the connecting pin. The special structure of the slotted lug allows the slag pusher plate to be adjusted in angle and orientation, either upwards or downwards: when the converter slag car moves forward, the connecting pin is offset backwards by the resistance from the slag, and the slag pusher plate performs slag pushing; when the converter slag car moves backwards, the slag pusher plate is rotated at a certain angle by the forward thrust, the connecting pin is offset forward by the slag pusher plate, the lower part of the slag pusher plate is raised, and the slag pusher plate stops working; when the slag pusher plate experiences greater slag pushing resistance, the connecting pin moves upwards along the slotted lug, and the slag pusher plate rises to a certain height to alleviate the resistance. The coordinated operation of the slotted lug, connecting pin, and lug seat makes the slag pushing process smoother.

[0010] Option 3, a preferred option of the basic scheme, features a curved plate-shaped pusher plate. Two rollers are located at the end of the pusher plate closest to the track, and these rollers are in rolling contact with the track. By setting the pusher plate as a curved plate with its convex surface facing the track, and by placing two rollers at the end of the pusher plate that contacts the track, the resistance encountered during the pusher process is further reduced, making the pusher process smoother.

[0011] Option 4, a preferred option of Option 3, features baffles on both sides of the slag pusher plate. The baffles allow the entire slag pusher to accumulate more slag while effectively preventing some slag from overflowing onto the sides of the track, thus reducing the frequency of slag cleaning.

[0012] Option 5, a preferred option of the basic scheme, also includes an extended panel. The second slag pusher plate has several rows of through holes, and the second slag pusher plate is connected to the extended panel via bolts through these holes. The through holes are arranged longitudinally with a certain spacing. Operators can adjust the position of the bolt connection between the second slag pusher plate and the extended panel according to the height of the slag accumulation in the slag pit, thereby adjusting the combined length of the two panels. Specifically, the combined length is shortest when the bolt connection is on the topmost through hole, and longest when the bolt connection is on the bottommost through hole. This connection method also facilitates the replacement of the extended panel by the operator. Attached Figure Description
