Slag blow-removal mechanism

Abstract

The invention provides a slag blow-removal mechanism comprising a guide rail frame, a lifting trolley, a slag blow-removal spray gun, a lifting transmission device, a tilting device and a hinging mechanism. The guide rail frame is obliquely arranged on the hinging mechanism; under the action of the tilting device, the guide rail frame can rock around a hinge pin of the hinging mechanism; the lifting trolley is slidably connected to the guide rail frame; the slag blow-removal spray gun is fixed to the lifting trolley, and the head of the slag blow-removal spray gun is located above the level of molten iron; the head of the slag blow-removal spray gun is a multi-nozzle arc pipe which is provided with a plurality of blow branch pipes arranged in an arc form; the lifting transmission device is disposed at the top of the guide rail frame and is used for driving the lifting trolley to slide up and down along the guide rail frame. The slag blow-removal mechanism has the advantages such that the mechanism is suitable for removing the slag under different heights of the molten iron and different tilting angles, the area of slag removal in same periods is large, the slag removal area is small, the efficiency is high, the operating time is short, many furnaces can be operated, the structure is simple, and maintenance is convenient.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, in particular to an air blowing and slag removing mechanism for molten iron desulfurization. Background technique [0002] In the process of steelmaking, the desulfurization slag on the surface of the molten iron must be removed from the molten iron after desulfurization treatment, so as to avoid resulfurization during steelmaking. Steelworks are equipped with slag removal machines and air blowing slag removal devices. The air blowing slag removal devices are auxiliary slag removal equipment for hot metal desulfurization. The removal of thin slag can improve the cleaning rate, thereby reducing iron loss and generating huge economic benefits for steel mills. At present, most air blowing and slag removal devices are inserted into the molten iron surface to a certain depth, and the molten iron is turned by blowing air, and the slag on the surface of the molten iron is gathered from ...

Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a non-inserted air blowing and slag removal mechanism, which is used to solve the problem that the existing air blowing and slag removal mechanism cannot adapt to different molten iron level heights and different tipping angles. The problem of slag removal and the small number of furnaces operated by the gun head
