Description

Device for preventing soot of wire feeding guide pipe of wire feeding machine from emitting outwards

Technical Field

The utility model relates to a molten steel refining technology field specifically indicates a device that prevents that wire feeder wire feeding pipe smoke and dust from emitting outward.

Background

The wire feeder is applied to the working procedures of a converter, an LF refining furnace, a VD vacuum furnace and the like, and the functions of adjusting molten steel components, modifying inclusions and the like are achieved mainly by feeding different wires. The LF refining furnace wire feeding process is to feed wires by passing a wire feeding guide pipe through a dust hood and inserting the wire feeding guide pipe into a wire feeding port of a water-cooling furnace cover; during smelting and wire feeding of the LF refining furnace, smoke and dust can emerge from a side gap where the water-cooled furnace cover is contacted with a steel ladle, an electrode hole on the water-cooled furnace cover and a wire feeding port on the water-cooled furnace cover and enter a dust hood, most of the smoke and dust are limited in the dust hood, and part of the smoke and dust enters an external space through a wire feeding guide pipe; the following consequences can occur: during power transmission in the early slagging stage, a large amount of yellow smoke dust is generated in the furnace, when a large amount of yellow smoke dust emerges from the outside of a wire feeding guide pipe port, the LF refining furnace must lift an electrode to stop power transmission, and then power transmission operation can be performed only after the amount of smoke dust is reduced; because the LF is used for producing reducing slag, repeated operation often occurs, and the normal temperature rise operation of the LF refining furnace and the normal connection of production are seriously influenced; in addition, the smoke can permeate the operation platform after emerging from the wire feeding guide pipe, so that the physical and psychological health of operators is seriously influenced, and accidents such as smoke inorganization emission and the like are easy to happen.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

Referring to fig. 1 and 2, a device for preventing soot from emitting outside a wire feeding guide pipe of a wire feeding machine comprises a dust hood 6 and a wire feeding guide pipe 11, wherein a plurality of wire feeding guide pipes 11 of a wire feeding machine main body are connected to a wire feeding port of a water cooling furnace cover 8 after penetrating through the dust hood 6, the wire feeding guide pipes 11 are provided with fixed joints 3 used for being connected with an argon conveying pipeline 2, and an angle formed by one ends, connected with the wire feeding guide pipes 11, of the wire feeding machine main body of the wire feeding machine is an acute angle.

Preferably, the angle formed by the fixed joint 3 and one end of the wire feeding guide pipe 11 connected with the wire feeding machine main body is 30-60 degrees.

Preferably, the argon conveying pipeline 2 is arranged outside the dust hood 6; the argon conveying line is convenient to arrange, and the smelting influence of the LF refining furnace is avoided.

Referring to fig. 1 and 2, the argon gas conveying pipeline 2 includes a main conveying pipe 22 and a multi-way joint 4, the main conveying pipe 22 is connected with a plurality of shunt pipes 5 through the multi-way joint 4, and the other ends of the shunt pipes 5 are respectively and correspondingly connected to the fixed joints 3 of the plurality of wire feeding guide pipes 11.
