Kievtractorodetal has many unique technologies,
which give us an edge over competing factories in price point
and productivity. For instance, the Ukraine Academy of Sciences
helped us to develop new pig iron for producing sleeves with
an inside diameter from 60 mm, outside diameter to 170 mm, length
to 650 mm. To make the sleeves we mold pig iron using melting
furnaces and then do further alloying in mixers using a special
duplex process. |
These
unique foundry processes consist of: magnetic & dynamic pumps/scales
for maintaining optimal temperature and so that liquid pig iron
can be automatically poured into reusable metallic molds; installations
for making forms using a centrifugal technique; devices for automatically
removing parts from their molds and transporting them to clearing;
finished parts are automaticly transported to work zone equipment. We
are also capable of manufacturing using more than 100 different
progressive technologies,
including:
casting technology for piston rings for internal combustion engines;
ladle and inside configuration technology for making different forms
using high
durability pig iron and others.
We create sleeves & pistons for internal combustion engines using
mechanical processing on highly productivity automatic lines.
Lines are equipped with a boring, turning grinding, and honing process
which is controlled by semiautomatic devices.
Most of the equipment used at Kievtractorodetal is unique.
In accordance with
technical requirements, we can make cylinder sleeves from different
types of alloying pig iron.
Depending on the engine type
and pig iron chemical composition, sleeves may be produced either with
or without thermal processing. We can make
them as flat-peak or as straight-peak microrelief on the inside working
surface. In the case of microrelief, we spread an anti-friction
covering using special whetstones. We also have aluminum piston processing
technology with oval & barrel form profile of the piston cup. For
piston and sleeve production, we employ technology which prevents damage
when the engine's breakin is in progress. This allows us to cut the duration
of
the break-in
time
of
the
sleeves & rings,
and to reduce in comparison with world level of 2.5 g/l.s. per hour. Our
methods are highly economical and effective. High technology allows us
to produce parts with the lowest cost of production in comparison with
other plants. |
