Abstract: A method and device are disclosed for aligning up a pouring mold tube in a continuous casting machine. The device has a mold insert portion having a pair of parallel faces which mate with the vertical parallel internal walls of a mold tube. A vertical alignment means is attached to the top of the mold insert portion and is adapted to indicate when the mold insert portion and hence the mold tube is in a vertical position. A radial and horizontal alignment means is also attached to the mold insert portion and is adapted to indicate when the mold insert portion and the mold tube are radially and horizontally aligned. The method includes the steps of inserting a mold insert portion of an alignment device between the vertical parallel walls of a mold tube and adjusting the elevation of the adaptor plate supporting the mold tube such that the alignment device is aligned vertically, radially and laterally.
