Description

Technical Field

[0001] The present application relates to the technical field of steel production, and particularly relates to a device for transporting and collecting scale on steel billets. Background Art

[0002] In the process of steel production, the steel billets need to be heated before rolling so that they can be more easily deformed and shaped in the rolling mill. This heating process is usually carried out in a special heating furnace. By raising the temperature of the steel billets, it reaches the conditions suitable for rolling. However, during the heating process, the surface of the steel billets will chemically react with the oxygen in the air to form a layer of oxide, that is, the so-called scale.

[0003] As the heating process progresses, the scale will gradually accumulate on the surface of the steel billets. When the steel billets are heated in the heating furnace and completed, they will go through a series of stepping processes, such as being removed from the heating furnace and transported to the rolling mill, etc. In this series of steps, due to the movement of the steel billets and contact with other equipment, some of the scale on their surfaces will fall off, and these fallen scales often enter the discharge chute and accumulate continuously as the steel billets move.

[0004] However, for the scale in the discharge chute, most current steel enterprises still adopt the method of manual cleaning. The workload is large, the temperature of the scale is relatively high, which is easy to cause scalding to personnel, and the heating furnace belongs to the gas area. There is a risk of gas poisoning when personnel clean it, so it needs to be improved. Utility Model Content

[0047] Start the second motor 33. The second motor 33 drives the second speed reducer 37 through a belt. The second speed reducer 37 drives the second rotating shaft 11 to rotate through the chain drive of two second reduction sprockets 38 and a second reduction chain 39, and then drives the second transmission sprocket 34 to rotate. Since the two second transmission sprockets 34 on the same side are connected by the second rotating shaft 11, they will rotate synchronously. Two second transmission chains 35 also start to move in a cycle, and several second scrapers 36 move along with the movement of the chains, thereby pushing the scale piled on the second slag plate 32. The scale is conveyed to the end of the second drag chain scraper conveyor 3 and finally collected into the pit ash hopper 5 through the telescopic chute 4, completing the conveyance and collection of the scale; through the arrangement of the first drag chain scraper conveyor 2, the second drag chain scraper conveyor 3 and the collection mechanism 6, it helps to realize the automatic collection and conveyance of the scale, greatly reducing the workload of the operators, improving the cleaning efficiency, reducing the downtime during the production process, improving the production efficiency.
