Example Embodiment

[0033] Example 1: When the device is performing the slagging operation inside the steel smelting furnace, first push the device to move to the slag outlet of the smelting furnace, and then pull the ring 4 to drive the container body 3 out , And close to the bottom end of the slag outlet, and then activate 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 removal The plate 7 and the second slagging plate 9 are rotated to increase the angle between the plate and the moving plate 5, and then the second hydraulic lever 16 is activated. The second hydraulic lever 16 pushes the limit bar 6 to slide inside the limit slot 18. The limit bar 6 drives the moving plate 5 to slide on the top of the moving box 1, and drives the slagging device at the top to move to the inside of the smelting furnace as a whole, and then controls the first hydraulic rod 1...

Example Embodiment

[0034] Embodiment 2: After completing one slagging operation and preparing for the second slagging operation, when the first hydraulic rod 11 pushes the sliding block 12 to move again, the sliding block drives the connecting rod 13, and the connecting rod 13 then drives the mounting plate 14 And the horizontal plate 19 moves, the horizontal plate 19 moves while driving 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 slagging plate 9, so as to The waste slag adhering to the bottom surface of the second slagging plate 9 is scraped off, so that the slagging efficiency when the second slagging plate 9 is again slagging can be improved.

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...
