BS-EBM series Multipurpose Electron Beam Melting Furnace
- Related Products
A vacuum melting furnace for refining and producing ingots from high-melting point, active metals using various types of crucibles with the electron beam as a heat source. A compact melting furnace, suitable for small volume production as well as R&D. The crucible type, shape, material supply system and electron gun output can be selected to suit the application.
Horizontal rod feeder + Hearth + Draw cast moldRaw materials in the form of a rod are delivered as the EB radiation is performed, and drop into the hearth,
where the material is thoroughly melted, and poured into the water-cooled casting mold
The melting, and casting are performed in the water-cooled casting mold to produce ingots.
Vertical rod feeder + Draw casting moldMaterial is placed into the crucible for bar melting, or
a granular material can be fed from a feed mechanism.
The bar-melt crucible is attached to the horizontal rod feeder section to anable zone melting.
The zone-melted material is drip-melted into the draw casting mold that is attached to the vertical rod feeder
The vertical rod feeder is equipped with raise/lower and rotation mechanisms,
making it possible to perform the drip melting into the center of the draw casting mold to achieve stable setting speeds.
Material feed mechanism + Hearth + Rotating cylinder casting mold
Granular materials is fed into the hearth from the feed mechanism.
The material is pre-melted in the hearth, and then
poured into the rotating cylindrical casting mold
and the layers aresolidified
2 electron guns can be mounted2 electron guns can be mounted to suit the application and required output
It is possible to assign each electron gun to multiple targets during EB irradiation
such as to the hearth and the rotating casting mold, or to the rod
and the draw casting mold
Exchangable crucibles (button melt, bar melt, pouring crucible)There are 3 types of crucible that can be attached to the rod feeder section
These allow a variety of different materials to be processed
Each crucible is attached/ detached to an exchange flange on the tip of the rod feeder,
making it easy to exchange the crucuble
3 crucible types
(1) Water cooled for button melt
(2) Water cooled for bar melt
(3) Water cooled, pouring crucible
Compact installationThe BS-EBM was designed to be used even within a laboratory setting,
with the ceiling heights and installation space requirements kept to a minimum
(W 3.0 m x D 4.0 m x H 3.5 m)*1
*1 The instrument dimensiona and installation space requirements will vary
according to the drawn ingot size and selected electron gun power supply
Power supplies for a range of outputs
Can be choosen to suit the mounted electron guns and desired maximum power (30 kW. 100 kW/ 300 kW)
