び耐溶融ガラス侵食性を具備することが要求される。Generally, glass fiber is produced by charging molten glass heated to about 1000°C into a spinner, and then rotating the spinner to 170°C.
Molten glass is formed by rotating at high speeds of about 100,000,000 rpm, and ejecting molten glass by centrifugal force from a large number of pores that are radially bored along the side wall of the spinner. Therefore, the spinner is required to have high-temperature oxidation resistance, high-temperature strength, especially high-temperature creep rupture strength, and molten glass erosion resistance.
