<p>A process involving a static mixer for continuous production of metal alloy is such that molten metal is passed through a filter bed of loose particulate material exposed to atmospheric pressure. The alloying addition is made to the metal via a proportioning and feed device as the metal enters the filter bed. As a result the alloy components are dissolved in the molted metal and, due to the repeated division and reuniting of the streams of charge in the bed, the alloying elements are mixed with the metal before leaving the mixing chamber. The degree of mixing can be changed by changing the size of particles in the granular bed. The static mixer of this invention avoids the wear and high maintenance costs inherent in mechanical stirring devices.</p> |
