He had long been in the service of man.
ENGINEERING DESIGN PRODUCTION CBF
Projects of manufactures basalt continuous fibers adapted to local conditions.
1- Technology of production of basalt continuous fiber
Before the start of production of continuous basalt fibers on an industrial
plant large fraction of basalt rubble jaw crushed to the required fraction which
is 5-12 mm.
After selection of metal inclusions magnetic separation method, a basalt raw
materials represented in the form of fine gravel or chips with average grain
size of 5 to 12 mm is sieved off and washed with small impurities (dust, etc.),
after which it was dried under normal conditions in the natural
air circulation through ventilation or a special drying apparatus (depending on
climate conditions of production).
With the help of crane or hoist basalt chippings washed periodically loaded into
the hopper loader installed on the melter.
The melting furnace is a regenerative continuous tank furnace with direct gas
heating of the melting zone.
In the furnace basalt raw material melts, and it comes after homogenization the
melt in the feeder for the subsequent molding thereof feeders complex continuous
Melting is carried out at a temperature of crumbs (1500 ± 50) ° C in the
combustion of the gas air mixture, which consists of natural gas and air.
Combustion air is supplied from the high-pressure fan through a heat exchanger-recuperator,
where it is heated with heat of exhaust gases to a temperature of 450 - 600 ° C,
and the gas supplied from the gas distribution substation (EMG).
The melt from the feeder of the furnace fed by gravity to the feeder at the
bottom of which there are dispensing devices 6, through which the melt is fed to
a platinum rhodium, bushing, where the formation of elementary CBF.
The melt from the feeder through a platinum drain device (jet feeder) with
electric heating is supplied into a platinum, bushing with electric heating,
wherein the spinnerets forming a strand of elementary filaments as the filaments
by drawing and winding them to a pulling device.
Strand filaments on a roller enters the pulling device, which applies a
lubricant after lubricant layer coating its filaments are collected in a
Integrated thread passes Nita Expanding apparatus wound on his removable spool.
As the winding bobbin with the yarn withdrawn from a bobbin of the winding
machine and replaced with a new reel.
Winding on bobbins apparatus is formed multifilament yarn (CN), which consists
of 1200 elementary CBF.
Wound bobbin maintained day under normal conditions, and then come to the
department for rewinding the roving with the necessary number of additions.
After rewinding the roving to the finished coils labeled and wrapped with paper,
then packed in wooden crates and enters the composition of the finished product.

- Raw material:/Сырье
Basalt rubble as a single component raw material for basalt continuous fibers
must be developed to certify career, representative examples of which have been
laboratory and pilot tests with a positive result. Raw materials from rocks is crushed average, basic and ultrabasic rocks
metamorphosed volcanic basalt types: basalts, gabrro, amphibolites, diabase,
porphyry and others (hereinafter referred to as the raw material). Raw materials
should be radiation-safe. Equivalent dose of ionizing radiation should not exceed 0.30 mSv / h. The materials must not contain impurities in the form of metal, quartz, sand
and clay and other rocks. The raw material is delivered in the form of a fraction, characterized by the
smallest and largest nominal grain size of 5 mm and 12 mm.
The content of grains smaller than 5 mm should not exceed 10% by mass, the grain
size of more than 12 mm and should not exceed 10% by weight.
