An apparatus for continuously casting molten metal, in which a vibrator (30, 31) is connected with a mold tube (20) to cause the mold tube to vibrate with a high frequency and low amplitude during casting of the metal to prevent adherence of the metal to the mold and also to improve the quality of the cast metal. A liquid metal, particularly steel or other high temperature melting point (2600<o>F and above) metal, is poured into a mold (20) which initiates solidification of the molten metal, and in which the mold (20) is vibrated at a frequency in the range of from about 1000 to about 12000 cycles per minute and at an amplitude in the range of from about 0.00078 to about .1250 inch, thus preventing adherence of the metal to the mold while at the same time improving the quality of the cast metal. The mold (20) is vibrated by one or more vibrators (30 and 31) connected to the mold tube (20) through a keeper plate (21, 22). A method of continuously casting molten metal, wherein molten metal is continuously poured into a mold tube (20) and the mold tube is vibrated with a high frequency and low amplitude to prevent adherence of the metal to the mold and also to improve the quality of the cast metal. |
