Slagging-off system of large smelting furnace

Abstract

The invention discloses a slagging-off system of a large smelting furnace. The system comprises a deslagging pit, the large smelting furnace, a casting ladle and a crown block, wherein the deslaggingpit is arranged below a molten iron outlet of the large smelting furnace, dross on the surface of the large smelting furnace is manually pushed to the deslagging pit, a slagging-off platform is arranged beside the deslagging pit, and the slagging-off platform comprises a fixed platform arranged on the outer side of the deslagging pit, a rotating platform hinged to the fixed platform and a rotatingdriving device used for driving the rotating platform to be unfolded or folded. When the dross on the surface of the large smelting furnace needs to be removed, the rotating platform is unfolded andlocated above the deslagging pit; and after the dross on the surface of the large smelting furnace is removed manually, the rotating platform is folded and located on the outer side of the deslaggingpit. The system is simple in structure, and the potential safety hazard that a worker can fall into the deslagging pit when removing the dross on the surface of molten iron can be eliminated on the premise that the receiving for molten iron after smelting by the casting ladle is not interfered.

Description

technical field [0001] The invention discloses a slag removal system, which belongs to the technical field of casting equipment, and specifically discloses a large slag removal system for a smelting furnace. [0002] technical background [0003] Large-scale smelting furnaces (more than 5 tons of melting furnaces) are essential equipment in the field of metallurgy and casting, which can melt metal ingots and some scrap metals and add necessary alloy components, and smelt them into required liquid metal equipment. In the prior art, when a large smelting furnace is used to smelt molten iron, the dross in the furnace body will float on the surface of the molten iron during the remelting process. It causes high slag content in the smelting metal liquid and the transfer of a large amount of gas, and in severe cases, the castings are scrapped. [0004] In order to solve this technical problem, workers generally remove the slag floating on the molten iron manually in the factory. ...

Problems solved by technology

In the prior art, when a large smelting furnace is used to smelt molten iron, the dross in the furnace body will float on the surface of the molten iron during the remelting process. It causes high slag content in the smelting metal liquid and the transfer of a large amount of gas, and in severe cases, the casting will be scrapped

[0004] In order to solve this technical problem, workers generally remove the slag floating on the molten iron manually in the factory. The workers take the crane with a hanging basket to the side of the large smelting furnace, and use auxiliary tools such as manual slag removal rods to remove the slag floating on the large smelting furnace. The scum on the surface of the inner molten iron is removed to the slag discharge pit. Since the hanging basket is suspended on the crane through the hook of the crane, the worker will cause the hanging basket to shake during the slag removal process, so that the spider plant may turn over and the worker will fall into and out of the pit. The slag pit was scalded by iron slag, so the existing slag removal operation has a major safety hazard
