TECHNOLOGY OF ELECTRIC MELTING OF BASALT FOR OBTAINING MINERAL FIBER

The basalt electric melting advantages in application of basalt fi ber in industrialized construction and heat power engineering are shown. The results of thermodynamic calculations of the process of Kazakhstan basalt melting are given. The calculations have shown that in gaseous and condensed products of the process there are no harmful substances. Experiments on electric melting of basalt in a reactor with electromagnetic mixing of the melt were carried out. The prospects of electric melting of basalt and obtaining mineral fi ber with the use of small-size module installations involving an electromagnetic reactor are shown. The specifi c energy consumption for obtaining a homogeneous basalt melt does not exceed 1.1 kW·h/kg, which is superior to the widely used SHF-reactors in which the specifi c energy consumption is several times higher
