Technology for producing mineral fiber using electric arc plasma

The paper presents the results of experimental studies of obtaining mineral fibers using electric arc air plasma. It has been established that with the optimal operation of the plasma generator (power P = 35.2-56 kW and specific heat fluxes q = 1.8-2.6 106 W/m2), the melt is homogenized in a melting furnace, which ensures the further formation of fibers with a minimum number of inhomogeneous inclusions, the specific energy expenditures upon receipt of the melt are 1.5-2.1 kW / kg, which is 2-2.5 times less than in the existing technologies.
