The author described the first results of testing corundum-graphite products for machines for continuous billet
casting, which are produced in the new corundum-graphite shop of the Dinur Company. Specifications of the
products are given.
The construction of a new shop (manufacture of corun
dum-graphite products) at the Dinur JSC was completed in
November of 2005. This is the main investment project of
the year, which lasted 15 months. Production of corundum-
graphite parts is implemented by a technology licensed from
the Fresema company (Switzerland) using state-of-the-art
machinery. Preparation and dosing of mixtures is performed
using Kramecz Ltd. equipment (Fig. 1), compaction is per-
formed on an EPSI (Belgium) hydraulic press (Fig. 2), and
firing and glazing — in furnaces produced by Horn Thermo-
process Machinery (Germany) (Fig. 3). All products undergo
total x-ray control on a GE Inspection Technologies (Ger
many) unit to discover concealed defects and deviations in
the wall thickness or coaxiality of the inner channels. The in
stallation and start-up of machinery, as well as personnel
training, was carried out with the participation of German
The new division has produced experimental lots of
refractories for machines for continuous billet casting: pro-
tective pipes, dosing nozzles, and submersible nozzles.
These products were tested at the N. Tagil, Magnitogorsk,
Oskolskii Electromelting, West Siberian, and Cherepovets
Metallurgical Works. At present, more numerous prototype
prodicts are being tested under industrial conditions. The
testing results demonstrate that the service parameters of the
products are not inferior to the parameters achieved by Vesu
vius (Germany), Shinagawa (Japan), TUK (Japan), and Dal
