Gas-electric OVEN FOR PRODUCING FIBER FROM ROCKS, MAINLY BASALT

摘要

The invention relates to equipment intended for the production of fibers from rocks, preferably basalt, namely furnaces for the melting of basalt. The furnace comprises a charging unit 1, the cooking chamber 2 and 3 generate, electrical heating elements 4 and the gas burner 5, a feeder 6. The feeder 6 and the heating elements 4 are made of heat-resistant high-chromium steel. The heating elements 4 in an amount of not less than 10 pieces arranged symmetrically ascending curve along the horizontal axis of the furnace at a distance from one another of 300-350 mm. Gas burners 5 minimum power installed in the furnace at an angle to the bath surface. The furnace provides a homogeneous melt from basalt low zauglerozhennostyu allowing basalt fiber to receive a high degree of plasticity.
