Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and in particular relates to a fast-changing conduit for a wire feeding machine. Background Art

[0002] The wire feeder is one of the main equipments that are indispensable in the refining process outside the furnace. In the smelting process of the LF ladle furnace, the wire feeder deoxidizes the steel slag by feeding aluminum wire to create a reducing atmosphere to create conditions for the desulfurization of molten steel, and feeds calcium wire to treat aluminum-killed steel to improve the castability of molten steel. The wire feeder is generally composed of a machine body and a guide tube. The wire directly enters the guide tube through the guide wheel. In the actual production and use process, it may encounter difficulties in threading, wire jamming, and the guide tube is thin and easy to bend and deform. The wire feeder needs to replace the guide tube frequently, which affects the production rhythm.

[0003] The above-mentioned existing wire feeding machine conduit has the following disadvantages: the replaceable conduit has the same diameter as the elbow, and the two are connected by a sleeve. Since the wire is hard, it is easy to get stuck at the conduit interface at both ends, which makes it very difficult to change the wire. It is easy to cause wire jamming and wire pile-up in production, affecting the processing speed and causing a tight production rhythm. In addition, the current steel liquid calcium treatment process mainly uses the wire feeding machine to feed the calcium wire into the steel liquid through the conduit. If the conduit is close to the steel liquid surface during the calcium feeding process, it is easy to burn and deform.

[0004] In view of the above factors, a wire feeding machine quick-change guide tube is specially designed to facilitate the operator to quickly replace the guide tube and solve the problem of wire jamming and wire piling, while extending the service life of the guide tube. Utility Model Content

[0005] The utility model aims to provide a fast-changing guide tube for a wire feeding machine, so as to solve the problems raised in the above-mentioned background technology.

[0010] Furthermore, the first connecting member and the second connecting member are nut structures or connecting rings made of metal material.

[0011] Furthermore, the first connecting member and the second connecting member are symmetrically arranged along the circumference of the first connecting pipe section and the second connecting pipe section.

[0012] Furthermore, the cross-section of the end of the second connecting pipe section is a conical surface structure, and a through hole is opened at the end of the second connecting pipe section.

[0013] Furthermore, the second connecting pipe section is a double-layer cavity structure, and the distance between the double-layer cavities of the second connecting pipe section is greater than the length of the screw provided on the second connecting piece.

[0014] Furthermore, the outer thickness of the second connecting pipe section is greater than the inner thickness, and a casting material is arranged in the double-layer cavity of the second connecting pipe section.

[0015] Furthermore, the ends of the first connecting pipe section and the second connecting pipe section are detachably connected to the first connecting member and the second connecting member by bolts.

Nuts or connecting rings are welded to the ends of the curved conduit and the straight conduit, which are fastened by iron wire and can be quickly replaced. The probability of wire jamming is reduced and the speed of fault handling is improved.

[0022] In order to increase the durability of the second connecting pipe section in the form of castables in the use state, the outer thickness of the second connecting pipe section is greater than the inner thickness, and the castables are arranged in the double-layer cavity of the second connecting pipe section.

[0035] In order to facilitate the sliding sleeve to improve the wire feeding effect in the use state, the distance between the first connecting member 4 and the second connecting member 5 is one third or one half of the length of the second connecting pipe section 3.

[0036] In order to facilitate connection in use, the first connecting member 4 and the second connecting member 5 are nut structures or connecting rings made of metal materials.

[0037] In order to ensure the overall stability in use, the first connecting member 4 and the second connecting member 5 are symmetrically arranged along the circumference of the first connecting pipe section 2 and the second connecting pipe section 3 .
