Adding a partition block in the furnace chamber is another way of changing the pathway for radiative heat transfer and controlling the melting process.
Then, the power distribution ratio between the top and side heaters is set to 5: 5 and 10: 0 in both furnaces to investigate the effect of power distribution and partition block on seed preservation.
Therefore, we installed a partition block in the space just above the heat exchange block and between the crucible and side insulation, as shown on the right in Figure 1.
Therefore, the partition block design can preserve the seed crystals, while the effect of power distribution is limited.
Based on the above analysis, a partition block was installed in an experimental DS furnace to produce QSC silicon ingots with the top heater occupying all the heating power.
Therefore, from this point onward the terms "partition block," "patrol sector," and "sector" will be used interchangeably.
Constraints (10)-(12) represent the conditions held by partition P defined on N; that is, P should not contain the empty set 0 (10) and the partition blocks cover N (11) and are pairwise disjoint (12).
