Articles of quartz ceramics used in casting nonferrous metals

The Pervouralskii Dinas Plant JSC has begun the production of quartz ceramics for installations for semicontinnuous casting of preforms of copper and copper-bearing alloys. Industrial tests of an experimental batch of articles (bushings, stoppers, rods, etc.) conducted in the second half of 1996 have shown that the durability of the quartz articles exceeds that of graphite articles conventionally used by a factor of 1.5–2.
