Abstract
The invention relates to a device for improving atomization quality by outflow of annular liquid metal. The device comprises a smelting furnace, a crucible, a flow guiding pipe, an outflow opening, a central core, a positioning disc, a graphite plug and an atomizer. Particularly, in a spray forming process, the outflow form of the liquid metal is changed by changing the structure of the outflow opening of the crucible, so that liquid metal flow is contacted with atomized gas for atomization in a hollow jet flow mode; therefore, atomization pressure is not required to be improved, and the aim of improving the atomization quality on the premise of higher mass flow rates is fulfilled. Simultaneously, the annular liquid metal has larger area in the spraying process, so that development tendency requirements on production of large-sized deposition blanks can be met, and a spray forming technology is promoted to be applied in the actual production process.
