Embodiment 1

[0033] Embodiment 1: When the device performs slag removal operation inside the steelmaking smelting furnace, first push the device to move to the position of the slag outlet of the smelting furnace, and then pull the pull ring 4 to drive the containing box 3 out , and close to the bottom of the slag outlet, and then start the control switch, so that the first hydraulic rod 11 pushes the slider 12 to slide inside the chute 10, and the slider drives the scraping device to move as a whole, so that the first slag scraper The plate 7 and the second slag removing plate 9 rotate to make the angle between them and the moving plate 5 larger, and then start the second hydraulic rod 16, and the second hydraulic rod 16 pushes the limit bar 6 to slide inside the limit groove 18, The limit bar 6 drives the moving plate 5 to slide on the top of the moving box 1, and drives the slag removal device at the top to move to the inside of the melting furnace as a whole, and then controls the first ...

Embodiment 2

[0034]Embodiment 2: When the first slag removal operation is completed and the second slag removal operation is ready, when the first hydraulic rod 11 pushes the slider 12 to move again, the slider drives the connecting rod 13, and the connecting rod 13 drives the mounting plate 14 and the horizontal plate 19, the horizontal plate 19 moves and drives the scraper 15 to move, and during the movement of the scraper 15, the spring 21 pushes the scraper 15 to slide against the bottom surface of the second slag removal plate 9, so that it can The waste slag adhered to the bottom surface of the second slag removing board 9 is scraped off, thereby improving the slag removing efficiency when the second slag removing board 9 removes slag again.

Abstract

The invention discloses a high-efficiency waste slag digging-conveying integrated device for steelmaking in a metallurgical plant, relates to the technical field of steelmaking, and aims to solve theproblem of inconvenience in cleaning waste slag after finishing of steelmaking in the existing metallurgical plant. According to the proposed scheme, the high-efficiency waste slag digging-conveying integrated device comprises a movable box, wherein a storage box is arranged inside the movable box in a sliding way; a crushing device is arranged inside the storage box; a movable plate is arranged at a top end of the storage box in a sliding way; two symmetrically-distributed mounting bases are fixedly arranged on one side of a top end of the movable plate; a first hydraulic rod is fixedly arranged on the mounting bases; and the side close to the mounting base of the top end of the movable plate is hinged with a first slag digging plate. Through the adoption of the high-efficiency waste slagdigging-conveying integrated device, the waste slag inside a melting furnace can be directly dug into the waste slag storage box easily, and the slag digging procedure is omitted. Meanwhile, the waste slag adhering to a bottom end of the slag digging plate can be scrapped in the slag digging process, so that the slag digging efficiency of the device can be effectively improved. The high-efficiency waste slag digging-conveying integrated device is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a high-efficiency waste slag removal and transportation integrated device for steelmaking in metallurgical plants. Background technique [0002] Steelmaking refers to putting pig iron in a steelmaking furnace and smelting it according to a certain process to obtain steel. Steel products include steel ingots, continuous casting slabs, and direct casting into various steel castings. The steel usually referred to generally refers to the steel rolled into various steel products. After the smelting is completed, the waste slag inside the smelting furnace needs to be slag removed and transported. However, the efficiency of the traditional slag removal operation is low, and after the slag removal, it needs to be transferred to the inside of the slag holding container, which increases the burden of slag removal. process, and after the slag removal operation is completed, the waste s...
