Description

Technical Field

[0001] This utility model relates to the field of basalt fiber production equipment, specifically to a basalt melting and drawing large stencil device. Background Technology

[0002] Basalt fiber is a continuous fiber produced by melting basalt rock at 1450℃-1500℃ and then drawing it at high speed through a spinneret. Its strength is comparable to high-strength glass fiber. Basalt fiber possesses numerous excellent properties, including high strength, corrosion resistance, and high-temperature resistance, and is widely used in fiber-reinforced composite materials, friction materials, thermal insulation materials, the automotive industry, and protective applications.

[0003] In the production process of basalt fiber, the drawing spindle is a core component of the basalt fiber production line. It is mainly used to evenly distribute and draw the high-temperature molten basalt into continuous fibers. Its performance directly affects the diameter uniformity, strength, and production efficiency of the basalt fibers. Current drawing spindles lack a complete set of temperature control components, making it difficult to achieve real-time and precise control of the molten basalt.

[0004] Therefore, we propose a large perforated plate device for basalt melting and wire drawing. Utility Model Content

By controlling the current, the temperature of the first electrode 8 and the second electrode 11 is controlled, so that the temperature of the basalt melt is controlled within a suitable range.
