Apparatus integrated with ceramic bushing for manufacturing mineral/basalt fibers

An apparatus integrated with ceramic bushing/s for manufacturing from the natural heat softanable material (basalt rocks) the continuous basalt fibers (gathered into strand) at the diameters from 7 to 20 micrometers, and the coarse fibers from 20 to 100 micrometers in diameter having ductile/flexible properties. Wherein the ceramic bushing is designed to replace platinum-rhodium (Pt—Rd) metals which limit the efficiency of basalt fibers production and their commercial applications.

• Wherein the apparatus integrated with ceramic bushing/s comprises members:
• (a) Two melting chambers—members of apparatus of claim 1,
• (b) Two slopped valleys—members of apparatus of claim 1, consisting movable tipped valleys positioned each above other, wherein valleys provide melted rock turbulence to flow, wherein each valley appears an extension of other.
• (c) Horizontal platform—member of apparatus of claim 1, farther referred as melted rock material receiver is positioned inside of the furnace interior—collector.
• (d) Collector-member of apparatus of claim 1. Wherein collector appears an interior of furnace where glass body is homogenized at temperature 1450 C.
• (e) Feeder—glass body distributor-member of apparatus of claim 1. Feeder comprises two sleeves—foreheads where from basalt glass body is supplied to the bushings, wherein the upper part—top of bushing is extended 10-15 mm above the bottom of the feeder sleeves to prevent the entrance to the bushing high gravity high-melting points contaminants.
• (f) The ceramic bushing integrated with apparatus of claim 1, wherein the body of said bushing is accompanied by massive side walls. Wherein the internal space of the bushing is divided by intermediate plate into two volumes:
• the upper and the lower chambers.
• (g) The external induction-member of the bushing integrated with apparatus of claim 1, wherein the said induction heating is used to heat said basalt glass body inside of said upper chamber of said ceramic bushing
• (h) The internal cathode-anode electric heating member of bushing integrated with said apparatus of claim 1. Wherein electrode heating is located inside of upper chamber of apparatus, wherein internal electrode heating is considered as alternative to external induction heating
• (i) The internal electric resistance heating element member of said bushing integrated with apparatus of claim 1. Wherein the internal electric heater in a shape of longitudinally extended plate made from electric conductive material:
• (molybdenum, or disilicide of molybdenum (MoSi2);
• Cr—Re-M;
• Cr—Mo-M;
• Cr—As-M-based alloy, or Kanthal Supra MoSi (1900), from SiC (1650). Wherein heater is located inside of the lower chamber of said Bushing and above the discharge wall. Wherein the internal heater functionality is to provide basalt glass body heating inside of the lower chamber of bushing. Wherein an internal heating in shape of plate exhibit plurality of openings, wherein the functionality of the openings is to allow basalt glass body flow to the orificed discharge wall.
• (k) Discharge wall member of said bushing of claim 1, wherein discharge wall consisting plurality of ceramic orificed plates is attached to the said bushing from the bottom,
• (l) The external induction and/or the internal electrode heating is used to heat basalt glass body inside of the upper part of bushing. Wherein the heating of basalt glass body inside of upper part is used if the capacity of internally installed electric heater is not sufficient to maintain basalt glass body temperature inside of the lover volume (chamber) of bushing in range of 1450 C.
