AI Technical Summary
In the smelting process of ultra-low carbon and nitrogen stainless steel, the wire alloy recovery rate of the wire feeder is low, and the alloy wire is prone to coiling after entering the ladle, resulting in a low recovery rate.
A conical funnel and a wear-resistant steel pipe are installed on the water-cooled furnace cover of the LF furnace. The conical funnel is connected to the water-cooled furnace cover through a fixing hole, and the wear-resistant steel pipe extends directly into the refining ladle, shortening the distance between the alloy wire outlet and the liquid surface of the ladle and increasing the straightness of the alloy wire.
This effectively improves the yield of alloy wire entering the ladle, reduces coiling, and extends the service life of the steel pipe.

Description
TECHNICAL FIELD
[0001] The utility model relates to the field of furnace refining technology, specifically relates to a device for improving wire alloy yield of wire feeder. BACKGROUND
[0002] In the smelting process of ultra-low carbon and nitrogen stainless steel, alloy wire is put into a refining ladle by using a wire feeder in an LF furnace, and the alloy wire is melted into molten steel by relying on argon blowing agitation. Due to the characteristics of ultra-low carbon and nitrogen stainless steel, it is not allowed to use "bypass" argon blowing agitation to improve the yield of wire alloy during LF refining treatment. Since the distance between the wire outlet duct of the wire feeder and the liquid surface of the ladle is far, the alloy wire appears "coiling" and unloading after being fed into the water-cooled furnace cover, and most of the alloy wire has low yield.

[0003] In view of the problems of the prior art, the utility model aims to provide a device for improving wire alloy yield of wire feeder, which shortens the distance between the wire outlet of the alloy wire and the liquid surface of the ladle, increases the straightness of the wire entering the ladle, and eliminates the "coiling" phenomenon of the alloy wire entering the ladle.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0005] A device for improving wire alloy yield of wire feeder, comprising a refining ladle, characterized in that: a steel pipe is arranged on the refining ladle, one end of the steel pipe penetrates an LF furnace water-cooled furnace into the refining ladle, the other end of the steel pipe is provided with a conical hopper, and the conical hopper is provided with a fixing hole.
[0006] Preferably, the conical hopper is connected with the LF furnace water-cooled cover through the fixing hole by using a bolt.
[0007] Preferably, the steel pipe is made of wear-resistant material.
[0008] The utility model has the advantages of:
[0009] 1. The device for improving wire alloy yield of wire feeder shortens the distance between the wire outlet of the alloy wire and the liquid surface of the ladle by increasing the conical hopper and the wear-resistant steel pipe on the LF furnace cold water cover, increases the straightness of the alloy wire entering the refining ladle, and effectively solves the "coiling" and unloading phenomenon of the alloy wire entering the refining ladle.
[0010] 2. The wear-resistant steel pipe can effectively reduce the wear degree of the alloy wire on the steel pipe, prolong the service life of the steel pipe, and reduce the replacement frequency. BRIEF DESCRIPTION OF DRAWINGS
