PROCESS FOR THE PRODUCTION OF CONTINUOUS FIBERS FROM BASALT ROCKS AND THE DEVICE FOR IMPLEMENTATION THEREOF

摘要

The invention relates to the production of fibers from basalt rocks, to the structure of stone-melting furnaces and technological equipment for the production of basalt continuous fibers. The basalt raw material previously before the loading is heated to temperatures of 250-400 °C. The loading is carried out to the zone of maximum temperatures to 2000 °C of burner-charger flame, besides in the zone of loading, melting, outgassing and homogenization of the melt a low level of the melt of 5- is sustained by the general level of the melt in a bath furnace to . The device comprises the bath and the furnace feeder, which is a continuation of the bath, and over the furnace roof the charger with burners are placed. In the furnace feeder behind the baffle of the bath a bushing assembly is fixed under which the device for coating of oil agent and coiling machine are placed. Under the charger in the bottom of the bath an upward-projecting melting ground is fixed, providing the level of the melt from 5 to 70 mm.
