Background technology
Normally used wire feeding process in present smelting technology, belong to outside wire feeding process, its essential characteristic is that wire rod enters molten steel from smelting the solution outside: wire rod obtains power by feeding silk equipment, produce axial motion speed, then the rigidity of utilization itself enters smelting solution, enter solution on one side, Yi Bian dissolve and dissolve, reach the purpose of adjusting solution composition.
There is following problem in this silk mode of feeding:
1, the wire rod of feeding contacts first the solution top layer, namely begins the process of conducting heat and melting;
2, because the buoyancy of solution, after wire rod enters solution, always downward motion of very difficult maintenance.
More than two problems cause same result, be exactly that wire rod is difficult to enter into the solution depths, and the considerable part wire rod becomes branch to float to solution surface by the slag blanket oxidation of air or solution surface, the solubleness of the raw material that wire rod comprises in molten steel is not high.
Now because more and more higher to the quality of smelting metal, each wire rod of not only feeding a kind of composition, but want the wire rod of Multiple components, but it is very difficult to want wire rod space on the wire rod transfer roller of Multiple components to change, and quick-replaceable is possible hardly smelting under the rugged environment.
