This equipment is used to receive hot slag from a silicon manganese ore furnace. The original slag temperature is around 1200-1300 ℃. After heating, tempering, and insulation, the temperature reaches 1400-1500 ℃ and is continuously transported to a centrifuge for producing mineral wool.
This equipment is suitable for use in a production line with an
annual output of 30000 tons of slag cotton.
Purpose
The slag cotton insulation furnace is mainly used for insulation of
hot slag during the production process of slag cotton. Ensure that
the hot slag is maintained within an appropriate temperature range
for subsequent processing into slag wool, ensuring the continuity
of production and the stability of product quality.
Structure Design
Lining: It is a key part of the insulation furnace and usually
adopts a multi-layer structure. The insulation furnace in a certain
utility model patent has a side lining consisting of asbestos board
layer, ramming material layer, and carbon brick layer from outside
to inside, and a bottom structure consisting of high alumina brick
layer, refractory aggregate layer, and carbon brick layer from
bottom to top. The thermal conductivity of asbestos board layer is
low, which can effectively reduce heat loss; The pounding material
layer can enhance the structural strength of the furnace lining;
The carbon brick layer has good thermal stability, high temperature
resistance, acid and alkali corrosion resistance, and can be used
as a high temperature resistant layer to improve the service life
of the furnace lining.
Furnace shell: Generally made of steel plate, it plays a role in
supporting and protecting the furnace lining, while preventing heat
radiation and loss, ensuring heat concentration inside the furnace,
and maintaining a high temperature environment.
Performance characteristics
Excellent insulation performance: Through the design of multi-layer
furnace lining structure and the use of low thermal conductivity
insulation materials such as asbestos board, refractory materials,
etc., the heat transfer rate is effectively reduced, heat loss is
minimized, and the hot slag in the furnace can be maintained at a
high temperature level, meeting the process requirements of slag
cotton production.
Strong structural stability: The ramming material layer and carbon
brick layer of the furnace lining have high strength and wear
resistance, and can withstand the erosion and erosion of hot slag,
as well as the thermal stress generated by frequent temperature
changes. They are not easy to crack or fall off, ensuring the
structural integrity and service life of the insulation furnace.
Good thermal shock resistance: Materials such as carbon bricks have
a low coefficient of thermal expansion and can adapt well to
thermal shock under frequent temperature changes, reducing damage
to the furnace lining caused by thermal expansion and contraction,
improving the reliability and stability of the insulation furnace,
and reducing maintenance costs and production interruption risks.
