1. Development prospects
Basalt fiber is a continuous fiber made by melting basalt stone at 1450 ºC to 1500 ºC and then drawing it at high speed through a platinum rhodium alloy wire drawing plate. As a type of mineral resource, basalt ore is relatively abundant, inexpensive, and can be melted into fibers without the need for purification and filtration. Basalt fiber is similar to glass fiber, with properties between high-strength S-glass fiber and alkali free E-glass fiber. The color of pure natural basalt fiber is generally brown, with some resembling gold. The temperature resistance range of basalt fiber is relatively wide and can be applied in conditions ranging from -260 ºC to+800 ºC, while the applicable temperature of glass fiber is only between -60 ºC to+450 ºC. Its alkali and acid resistance are better than ordinary glass fiber, and its oxidation and hydrolysis resistance are also much better than glass fiber. Its elastic modulus is about 1.3 times that of glass fiber, which can reach 100GPa, while glass fiber is only 70-80GPa, and its tensile strength can even reach over 4000MPa. According to experts' predictions, the basalt fiber manufacturing industry will become one of the rapidly rising emerging material industries. Therefore, the development and research of basalt fiber production equipment have significant economic and social benefits.
2. Equipment Introduction
The single furnace used for the production of basalt fiber adopts a fully electric melting heating method, which can be used to produce high-performance basalt continuous fibers. This device has a high degree of integration, and all systems are organically centralized into one whole. Users only need to connect water and electricity, and add granular raw materials on the ground level to carry out wire drawing production operations; This device drives one leak plate for production, and a single device can achieve an annual output of 100 tons of basalt fiber. Flexible installation, this device can be installed and operated separately or in combination with multiple units.

Basalt fiber and its products have been applied in many fields as a new type of material, and the excellent characteristics of basalt fiber and market demand have led to its rapid development. However, due to the fact that the production process of basalt fiber is more complex than that of glass fiber. Therefore, mature basalt fiber production equipment will effectively ensure the stability of the fiber production process. Sichuan Dianshi Xuanwu Fiber Technology Co., Ltd. is a professional manufacturer specializing in basalt fiber - SUZHOU CMT is currently the only exclusive equipment manufacturer in China. The company has three patented technologies on this device.
