Title:
CASTING MOLD POURING METHOD FOR MOLTEN SILICON AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JPH11180711
Kind Code:
A
Abstract:

To make it possible to prevent the peel of a coating material of a casting mold by pouring molten silicon while lowering the casting mold by bringing the front end of a pouring spout and the top edge of the casting mold 10 into proximity to each other without contact.

A melting furnace 1 internally holding the molten silicon 2 is inclined to pour the molten silicon 2 into the casting mold 10 from the pouring spout 3. At this time, the front end of the pouring spout 3 moves like loci 3a, 3b, 3c, 3d of the front end of the pouring spout 3 by drawing the loci indicated by a curve 4. While the pouring spout 3 exist in the position of the locus 3a, the pouring is started by rising the front surface height of the casting mold 10 as shown by an ascending and descending distance 11. As the position of the front end of the pouring spout 3 descends like the loci 3b, 3c, 3d on progression of pouring, the position of the adequate height of the top edge of the casting mold 10 is computed by an arithmetic unit in accordance with therewith and the casting mold 10 is moved. The front end of the pouring spout 3 of the melting furnace 1 and the top edge of the casting mold 10 are always in proximity to each other, the pouring at a low head is made possible and the failure of the coating material in the casting mold 10 is averted.
