Abstract
In a process of producing monotectic alloys having a relatively large miscibility gap in a liquid state and having in a solidified state a minority phase, which is included in the matrix and has the shape of droplets and has a higher density than the matrix, a molten material which is heated above the segregation temperature is continuously cast at a high casting speed end cooling rats. In order to achieve a sufficiently good disoersion of the minority phase the molten material is cast in a vertical direction.

A process for producing monotectic alloys having a relatively large miscibility gap in a liquid state and having in a solidified state a minority phase, which is included in the matrix and has the shape of droplets and has a higher density than the matrix, which comprises heating a molten material above the segregation temperature and continuously casting the molten material vertically at a constant velocity of about 10 to 30 mm/s and cooling rate to form a strip having a thickness of 5 to 20 mm.
A continuous casting apparatus for producing a monotectic alloy, comprising a container for a molten feed material directly communicating through a casting nozzle made of ceramic material and having a flow area that is smaller than the cross-sectional area of the resulting casting, and an intensely cooled, vertical permanent mold having a short metallic cooling surface succeeded by means for contacting the continuous casting with water, and a cooling water supply.
