Abstract:
PCT No. PCT/SE95/00811 Sec. 371 Date Dec. 30, 1997 Sec. 102(e) Date Dec. 30, 1997 PCT Filed Jun. 30, 1995 PCT Pub. No. WO97/02485 PCT Pub. Date Jan. 23, 1997A method for contactless continuous temperature measurement of the solidification of metal alloys is described, according to which the melt to be analysed is rotated about a vertical axis in a cylindrical and concentrically positioned test piece (2), and the temperature measurement is effected with the aid of an optical temperature meter (6). Upon rotation, a parabola-shaped inner surface forms, and the temperature measurement is performed on a part of the upper interface of the parabola.
