Technical and economic indices are presented for OAO Dinur operation in 2005 – 2007. The most promising
developments and test results are covered in the field of trough low-cement and ultralow-cement corundum
mixes, mullite-corundum refractories, corundum-graphite objects, sets of ladle refractories for furnace-ladle
units (FLU) based on high-alumina and periclase-carbon-containing objects. Refractory grades MLP and
MKP-72 based on andalusite for lining anode firing furnaces are presented as an advanced development.
The contemporary state of the Russian refractory indus-
try, its production capacity, the level of technology and prod-
uct quality make it possible to satisfy successfully the needs
of domestic metallurgy, to resolve new tasks, and to intro-
duce new high-quality technology rapidly. Enormous experi-
ence has been obtained of work under market conditions: at
first there was a drop in production, then recovery, renewal
and improvement of production units and products under
stringent competition with overseas enterprises, i.e. refrac
OAO Pervoural’sk Dinas Plant is one of the Russian
Federation industrial enterprises specializing in producing
refractories and refractory materials for the glass industry,
metallurgical production, and embracing within its range,
coke by-product, blast furnace, rolling, steel-pouring and ag
glomerated lime production. The enterprise has experience
and production resources for the building industry, it is pre
pared to present to the market results of development of
modern technology in the field of refractories for nonferrous
metal producers and the cement industry.
The level of technological development and engineering
equipment of OAO Pervoural’sk Dinas Plant makes it possi
ble to provide customers with high quality products competi
tive with respect to the well-known refractory producers of
Europe, China and Japan (RHI, Vesuvius, RI, Mayerton,
Dalmond, Choe Sun, Duferco, Shinagava, TUK), and also in
the RF (OAO Bogdanov Refractories, Borovich Refractory
Combine, OAO Semiluk Refractory Plant, OAO Snegirev
Refractory Plant, OAO Kombinat Magnezit, OOO Nikom-
ogneupor). The main customers of OAO Pervoural’sk Dinas
Plant are all the large metallurgical enterprises of the Russian
Federation and a number of enterprises abroad (Ukraine,
Kazakhstan, Uzbekistan, Poland, Egypt).
OAO Pervoural’sk Dinas Plant is dynamically develop-
ing production, specified by an increase in the volume of
product and the main financial indices since 2005, and the
plant may be characterized as a flexibly transforming enter
prise with changes in the competitive market with a capacity
to complete its orders under different market conditions. By
predicting even in 2005 a sharp reduction in orders of dinas
refractories, collectives of the enterprise set up new forms of
products that made it possible to increase the number of or
ders for ladle carbon-containing and high-alumina
refractories, to obtain orders for corundum-graphite objects
for steel pouring, high-alumina refractories for blast furnace
operation and heating furnaces. If we return to the statistics,
then the increase in production of new forms of product in
2005 with respect to 2004 was 43.1% and it continued to in
crease in 2006 and 2007 (Table 1). The overall output of re
fractory product in 2005 was 678 thousand tons, in 2006 it
was 705 thousand tons, and in 207 it was 714 thousand tons.
With an increase in production in 2005 and maintenance of
the position in 2006 and 2007 there were favorable dynamics
for the main technical and economic indices: with an in
crease in production, realization and output of saleable prod
uct and wages.
During 2007 the plant continued to increase investment
in development and improvement of production and the so
