FIELD: mining.
SUBSTANCE: furnace has an assembly of loading of welding and production camera, electric heating elements, gas burners and a feeder. The feeder and heating elements are made of heat-resistant high-chromium steel. The heating elements numbering at least 10 pieces are located symmetrically on the ascending curve along a horizontal axis of the furnace at a distance 300-350 mm from each other. Gas burners of the minimum power are installed in furnaces at an angle to a melting mirror.
EFFECT: obtaining of homogeneous basalt melt with low carbon content allowing to obtain basalt fibre with high degree of plasticity.
