Comparative evaluation is given for production and application of contemporary quartz steel-pouring ladle
refractories for OAO Dinur CBCM production with similar corundum-graphite refractories produced in the
Russian Federation by overseas technology using imported equipment. In spite of numerous predictions the
actual 45-year practice of continuous improvement of quartz refractories demonstrates their good viability.
Good technical and economic efficiency of their production and application is achieved by implementation of
HCBS- and ceramic concrete technology with application of unique centrifugal molding used for the first time
on an extensive industrial scale.
Keywords: fuzed quartz, quartz steel-pouring refractories, CBCM, corundum-graphite refractories, centrifu-
gal molding, HCBS, ceramic concrete.
Taking account of contemporary international relations
the question of national technological security is of primary
importance for the country. Therefore in this stage of devel
opment of industry and the economy aspects of import sub
stitution are very important, and also development and indus
trial application of competitive domestic technology.
QUARTZ AND CORUNDUM-GRAPHITE
COMPARATIVE EVALUATION OF TECHNOLOGY
As applied to the field of production and application of
refractory materials in the areas in question, industrial tech
nology of quartz refractories is very effective, implemented
and constantly improved within OAO Dinur over the extent
of about 30 years [1 – 7].
In contrast to slip-cast quartz refractories of similar com
position, produced in the Podolsk Refractory Object Plant
(PZOI) from the start of the 1970s [1, 2], quartz centrifugally
molded refractories of OAO Dinur with a ceramic concrete
structure, manufactured through a license of the firm
Kerambet-Ogneupory, due to improved service life and re
duced cost even at the start of the 2000s entirely displaced
from the market similar PZOI objects [1, 2, 4]. It is surpris
ing that over the extent of four decades among some special
ists (both metallurgists and refractory workers) were of the
opinion of the hopelessness of this class of domestic steel-
pouring refractories. This mistake was based to a consider
able extent on overseas practice, where there is preferred ap
plication of quartz refractories, but more expensive and sig
nificantly more complex corundum-graphite refractories
with respect to technology .
It should be noted that in the domestic market for
refractories CBCM in the last decade unprecedented compe
tition is noted of both Russian and the best overseas produc
ers. Corundum-graphite objects, supplied by the firms Vesu
vius, Shaniagawa, Dalmond, and Mayerton, even at the start
of this century, won a significant part of the market concern
ing output of special steels, for example manganese steels,
and those of various mass production (NTMK, OEMK, etc.).
