The technical development of basalt continuous fiber can be divided into three generations: the first generation is the manual feeding all-platinum crucible wire drawing process; The second generation is the combined drawing furnace drawing process with more than two leaky plates; The third generation is the pool kiln wire drawing process. Basalt fiber tank kiln technology is an important symbol to measure the basalt continuous fiber industry into a mature stage of development. The difficulty of basalt fiber pool kiln technology is different from that of glass fiber pool kiln. Because basalt contains more than 10% Of FeO and Fe2O3, it is difficult to control the REDOX atmosphere of the black melt and furnace in the melting process.
The number of holes in the drawing drain plate is one of the main indexes to measure the advanced basalt continuous fiber equipment. In the industrialization period of basalt continuous fiber, 200 hole leakage plate is widely used at home and abroad. With the progress of technology, basalt continuous fiber production enterprises at home and abroad gradually adopt 400 hole, 800 hole leakage plate; Now, with the development and application of pool kiln technology, the production technology of drawing large leakage plate with 1600 holes, 2400 holes and even larger holes is gradually realized, which provides help for the low cost of basalt continuous fiber.
The main advantages of our company are as follows:
1. Originate the new technology of pool kiln drawing, 2400 hole large bushing kiln drawing,high yield.
2. The homogenization process of raw materials ensures the stability of basalt wire drawing quality.
3. Top oxygen combustion technology ensures to minimize energy consumption and save cost .
4. Three senior academicians of Chinese Academy of Sciences serve as our technical advisors.
5. With high degree of automation, the subsequent finishing process of raw silk adopts robot transportation and operation.
