SILICON CARBIDE SiC BRIQUETTES, FeSi
BRIQUETTES
KORUND Benátky, s.r.o.
We
produce foundry briquettes in wide assortment and two
basic groups:
1) Silicon
carbide briquettes,
briquet SiC
Silicon carbide briquettes SiC are
produced in content of 50% and 70% into different forms.
Mostly are produced silicon carbide briquettes SPECIAL 70% in size
of 10 x 10 x 11 cm, packed are on palettes for 1.000 kg.
These briquettes are determined for cupola furnaces with
manual batching.
|
 |
|
For__machine_
batching are produced silicon carbide briquettes of hexagonal shape in
size of 9 x 10 cm with content of 70 % or 50 % SiC.
These silicon carbide briquettes are supplied either in bulk or in big-bags.

2)
FeSi briquettes
We produce FeSi
briquettes in content of 65 % and 50 % of clear Si. For
a production of briquettes is again used several types
of forms. For manual batching are mostly supplied
briquettes in size of 10 x 10 x 11 cm. For machine
batching we supply briquettes in size of 4,5 x 4,5 x 5
cm.
The whole
production of briquettes is during a process checked by
intra-plant laboratory, which assures high grade
briquettes.
Briquettes are supplied to foundries all over the Europe.

Silicon carbide SiC
Silicon
Carbide is produced in resistance furnace, where exact
mixtures of petroleumcoke and siliceous sand are burnt
Silicon Carbide arise by increasing of crystals in the
core of furnace during smelting.
| SILICON CARBIDE AND CORUNDUM MIXTURES TO INDUSTRIAL FLOORS |
|
After cooled,
furnace is disassambled, material is sorted and
according to the quality is classified to material
suitable for a production of abrasive grains and
material suitable for metallurgy.
For a production of abrasive grains is used material with silicon carbide
SiC content min. 98%. For
metallurgical_purposes is
used material with silicon carbide SiC content minimal
90%. Silicon carbide SiC 98% is further crushed and on sorting lines formed and
classified to different types of abrasive grains. All
production process is permanently checked by internal
laboratory which assured 100% conforming to
technological method and following creation of quality
abrasive grains.
Silicon Carbide black is mainly used for a production of abrasive tools
and instruments. Among further possibilities of usage
belongs blasting by dry and wet method, production of
refractory blocks, bricks, refractory cements and
compacting mixtures.

USAGE OF
SiC BRIQUETTES BRINGS
CONSIDERABLE ECONOMICAL EFFECTS
|
In electrotechnical industry for a production of insulating materials and
lightning arresters. Wonderfuly is asserted as addition
to laminated and frame saws at cutting of stone, then
as filling agent to an epoxy resins for increasing of
resistance against
wear.
