Basalt fibre is a type of continuous fibre prepared from natural volcanic rock and ore after melting at high temperature. The raw material for basalt fibre (andesitic basalt, andesite basalt, diabase and other volcanic rock) belongs to the family of inorganic nonmetallic silicates and is characterized by high Fe 2 O 3 or FeO content. The high Fe 2 O 3 /FeO content in turn …

Glass melting furnaces are designed and engineered to transform raw materials into molten glass. Molten glass is then transferred through feeder and forehearth to bushings to form fibres. These furnaces are made from special type of refractory material and heated with natural gas, electricity or combination of both. Technical Data.

Basalt fibers are produced from basalt rock using single component raw material by drawing and winding fibers from the melt. Once the basalt fibers have been produced, they are converted into a suitable form for particular application, such as (figure 1): ... then washed and moved into melting baths in gas-heated furnaces. under temperature of ...
