A kind of efficient anti-blocking quick replacing immerseable is fed silk braid pipe unit and method
Technical field
The present invention relates to metallurgical technology field, specifically
OnePlant efficient anti-blocking quick replacing immerseable and feed silk braid pipe unit and method.
Background technology
Usually using wire feeding process in the smelting technology at present, its essential characteristic is that wire rod enters molten steel from the outside that smelts solution: its mode is that wire rod passes through to feed silk equipment acquisition power, produce axial motion speed, the rigidity of utilization itself enters smelting solution then, enter solution on one side, fusing on one side and dissolving reach the purpose of adjusting solution composition.
There is following problem in this hello silk mode: 1, the wire rod of feeding contacts the solution top layer earlier, namely begins the process of conducting heat and melting; 2, because the buoyancy of solution, after wire rod enters solution, very difficult maintenance downward motion always.More than two problems cause wire rod to be difficult to enter into the solution depths, and the considerable part wire rod becomes branch to float to solution surface, easily by the slag blanket oxidation of air or solution surface, the raw material that wire rod comprises in molten steel solubleness not high.
Occur utilizing steel pipe to insert wire feeder in the recent period and fed silk; the application number of our company's application is 2012102801984; name is called the wire rod delivery bag and puts and method; though it has solved the problems referred to above; but also have this some serious weak points: wire feeder send shielding gas pipe and wire-feeding pipe as one; and this pipe leading portion immerses in the molten metal; use so repeatedly; work-ing life is short; the long life has only 400-500 times; and the productive expense of this root pipe is very high; minimum more than ten thousand yuan; each like this cost of use is all more than hundreds of unit, and shielding gas pipe and wire-feeding pipe all are to extend in the molten metal leading portion partly to ablate when using; stop up, it still is good that the shielding gas pipe is sent in the back; so just caused great waste; because use cost is very high, factory is difficult to accept such wire feeder, therefore is difficult to popularize.
Summary of the invention
The objective of the invention is research
OnePlant efficient anti-blocking quick replacing immerseable and feed silk braid pipe unit and method, use cost is low, uses and changes conveniently.
A kind of efficient anti-blocking quick replacing immerseable of the present invention is fed the silk braid pipe unit, comprising: the wire-feeding pipe of supplying gas, immerse in the molten metal and manage 2; Supply gas wire-feeding pipe, immerse 2 liang of pipes of pipe fastening connection pieces 3 in the molten metal.
Pipe 2 is refractory materials or refractory metal material in the described immersion molten metal.
Described fastening connection piece 3 is quick mode of connection, and it is for buckle connects, multi-step thread connects, pressure connects, taper sheath connection or other mode of connection.
The described wire-feeding pipe of supplying gas comprises: outer tube 1, be provided with wire-feeding pipe 5 in the outer tube 1, and the top of outer tube 1 is provided with inlet pipe, and the bottom of outer tube 1 is provided with bottom sealing plate, and production well is arranged on the bottom sealing plate, and wire-feeding pipe 5 passes bottom sealing plate.
Pipe 2 top links to each other with outer tube 1 through hole in the described immersion molten metal, and wire-feeding pipe 5 extend in the endoporus that immerses pipe 2 in the molten metal, and foot has an anti-blocking inside trumpet mouth or straight mouth.
A kind of efficient anti-blocking quick replacing immerseable of the present invention is fed the method for silk braid pipe, comprising: the wire-feeding pipe of supplying gas, and immerse in the molten metal and manage 2, the wire-feeding pipe 1 of supplying gas immerses pipe 2 two effective fastening quick change mode of connection in the molten metal.
The present invention
OneThe advantage of planting efficient anti-blocking quick replacing immerseable hello silk braid pipe unit and method is: whole hello fiber tube manufacturing is simple, cost is low, entering can be effectively anti-blocking in refractory materials in the molten metal or the use of high temperature metallic material pipe, being used to complete the back changes quick, and can the not high material of service requirements, greatly reduce each use cost like this, each use cost only original 1/5-1/10, also saved simultaneously metallic substance greatly, be easy to popularize, realize whole longer service life of feeding fiber tube simultaneously.

Embodiment
The root a tree name is shown in Figure 1, and a kind of efficient anti-blocking quick replacing immerseable is fed the silk braid pipe unit, comprising: the wire-feeding pipe of supplying gas, immerse in the molten metal and manage 2; Supply gas wire-feeding pipe, immerse 2 liang of pipes of pipe fastening connection pieces 3 in the molten metal.
Pipe 2 is refractory materials or refractory metal material in the described immersion molten metal.
Described fastening connection piece 3 is quick mode of connection, and it is for buckle connects, multi-step thread connects, pressure connects, taper sheath connection or other mode of connection.
The described wire-feeding pipe of supplying gas comprises: outer tube 1, be provided with wire-feeding pipe 5 in the outer tube 1, and the top of outer tube 1 is provided with inlet pipe, and the bottom of outer tube 1 is provided with bottom sealing plate, and production well is arranged on the bottom sealing plate, and wire-feeding pipe 5 passes bottom sealing plate.
Pipe 2 top links to each other with outer tube 1 through hole in the described immersion molten metal, and wire-feeding pipe 5 extend in the endoporus that immerses pipe 2 in the molten metal, and foot has an anti-blocking inside trumpet mouth or straight mouth.
A kind of efficient anti-blocking quick replacing immerseable of the present invention is fed the method for silk braid pipe, comprising: the wire-feeding pipe of supplying gas, and immerse in the molten metal and manage 2, the wire-feeding pipe 1 of supplying gas immerses pipe 2 two effective fastening quick change mode of connection in the molten metal.
The present invention is regardless of and is limited to an above-mentioned embodiment, root a tree name induction pipe wire feed, and the difference that immerses the mode of connection of pipe 2 in the molten metal can be formed a plurality of embodiment, does not tire out one by one at this and states.
