Description

Technical Field

[0001] The invention relates to a steelmaking and refining furnace wire guiding mechanism, belonging to the technical field of steelmaking. Background Art

[0002] The wire feeder is a kind of process equipment used in the metallurgical industry and steelmaking process. It is mainly used to inject alloy core wire or aluminum coil wire into the deep of molten steel at a reasonable speed and accurate quantity, so that it can be evenly dispersed in the molten steel to achieve the purpose of deoxidation, change the inclusion form, and fine-tune the composition. This process is a popular ray refining technology outside the furnace in the world today. In recent years, large and medium-sized steel companies at home and abroad have been promoting its use. The wire feeding system of the widely used refining furnace wire feeder has always adopted the working method of feeding wire with a covered fixed guide tube (see the specific structure) Figure 7 ), which consists of a wire feeder A, a fixed tube B, an anti-loosening mechanism C, a heavy hammer limit mechanism D, a plug-in door E, and a movable tube F. This working mode has problems such as unsmooth wire feeding, waste of alloy wire materials, and abnormal composition of molten steel due to the fact that the alloy wire outlet is far away from the molten steel surface (the distance is at least 1.6 meters).

[0003] These problems not only affect the production rhythm of the refining furnace, but also have an adverse effect on product quality; so we propose a steelmaking refining furnace wire guide mechanism to solve the above problems. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention realizes a substantial adjustment of the wire feeding position through the optimized design of the movable water-cooling conduit, so that the alloy wire can be more accurately injected into the deep of the molten steel, thereby improving the wire feeding efficiency and uniformity.

[0014] 2. The height of the conduit is adjusted by the power drive mechanism in cooperation with the traction wire rope, which shortens the distance from the alloy wire outlet to the molten steel surface, effectively reduces the waste of alloy wire, reduces production costs, and reduces the fluctuation of molten steel composition caused by unsmooth wire feeding.
