  • Patent number: 12508647
    Abstract: A casting apparatus for producing metal matrix composite materials includes a melt channel inclined in an apparatus flow direction, a flow pathway for a metal melt, and a particle feed device for adding solid particles to the metal melt. A casting method includes adding solid particles to a metal melt flowing in a continuous flow down a melt channel. The particle feed device is a shaft extending at least up to a base of the flow pathway and having a particle exit window in a casing of the shaft. The metal melt flowing down along the flow pathway is divided into two partial streams flowing around the channel projecting into and dividing the flow pathway. Where the partial streams combine again after flowing around the channel, the solid particles trickle into the confluence of the partial streams via a particle exit window in the channel located above the flow pathway.
