ABSTRACT:
The present invention relates to a method and apparatus for pouring molten material, such as molten metal, into a casting mold so that the amount of melt can be weighed in connection with the pouring. In order to keep the pouring height of the molten material low and its motion as smooth as possible during the pouring step, the bottom of the ladle containing molten material is designed to be essentially curved, with such a radius of curvature that the thickness of the molten layer located in the ladle is, even at its thickest, only a fraction of the length of the radius of curvature of the bottom. The casting method of the invention is advantageously realized by means of a cradle arrangement of the ladle according to the invention.
