The Sukhoi Log Refractory Plant was founded in 1932.
It has produced dense aluminosilicate (chamotte) objects and
steel pouring components. In the 1960s production was as
similated for lightweight objects with an apparent density of
1.3, 1.0 and 0.4 g/cm
. In 1973 for the first time in the USSR
a production line was put into operation for producing kaolin
wool (mullite-silica fiber) with a design capacity of
100 tons/year. In recent years the enterprise has carried our
technical re-equipment, improvement of technology and ex-
pansion of the range of products based on mullite-silica fiber.
In the 1900s the production capacity of three lines reached
12000 tons/year. Since 2006 all of the fiber and objects pro-
duced based on it have been transferred to a joint enterprise
Morgan Thermal Ceramic - Sukhoi Log (MTKSL). Within
the frame work of technical re-equipment work proceeded on
a new line for producing strengthened coiled fiber materials
without analogs in Russia and the CIS. Sale of all materials
has also been accomplished produced by Morgan Thermal
Ceramics, that is the largest producer in the world of
high-temperature heat insulation materials. It manufactures
products in 40 enterprises in 25 countries of the world.
The main properties of objects made of mullite-silica fi
ber are: a broad service temperature range (from 1150 to
1450°C depending on the chemical composition of the mate-
rial and its grade); improved heat insulating properties; low
weight; insignificant heat accumulation; high heat resistance
(resistance to thermal shock); good electric insulating prop-
erties; good filtering capacity; non-wetting by molten alumi-
num, zinc, magnesium and other alloys; good sound insulat-
ing properties; resistance to alkali and acid, with the excep-
tion of fluoric and orthophosphoric acids.
