<p><P>PROBLEM TO BE SOLVED: To prevent wear of parts of an apparatus for manufacturing quartz glass crucibles caused by silica fume and to control contamination of the quartz glass crucibles with wear debris, and debris of apparatus parts. <P>SOLUTION: The apparatus for manufacturing quartz glass crucibles is partitioned into a lower compartment in which a mold and a mold drive system are arranged, and an upper compartment in which an arc electrode drive system is arranged, and has a partition member provided with not less than one through hole through which the arc electrodes pass. The gas flow is controlled in a way to prevent exchange of the gas in the upper compartment with the gas in the lower compartment from occurring. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
