見出した。Focusing on the above points, the present inventors researched a method for producing glass fibers that have good cement alkali resistance and are inexpensive to produce, and discovered the following method. That is, the raw materials used in the present invention are industrially easily available, with little variation in quality, and are inexpensive raw materials such as window glass scraps (soda-lime glass) and steelmaking slag, To this, Jill L, -1 | As a result of experiments using various combinations of the above-mentioned Ξ types of raw materials, it was found that the following combination was suitable for producing glass fibers.

製鉄スラグ １０〜３腫量部
ジルコン高含有廃耐火煉瓦 ６〜１４重量部であつて、
ジルコニウムの含有量は５〜１０％の範囲にある。That is, the blending range is 60 to 8 parts by weight of soda lime glass waste, 10 to 3 parts by weight of iron slag, and 6 to 14 parts by weight of waste refractory bricks containing high zircon.
The content of zirconium is in the range 5-10%.
これらの原料は、それぞれ粉砕して微粉として混合する
もので、３００メッシュ通過した程度（４６μ以下）に
すれば溶融速度も早く適当である。These raw materials are ground and mixed as fine powder, and if the powder passes through 300 meshes (46 microns or less), the melting speed is fast and appropriate.
以上の配合物の溶融温度は１５００〜１５８０℃で溶融
時間もル分のように短時間で完全に溶融する。このこと

る。The melting temperature of the above compound is 1,500 to 1,580 DEG C., and the melting time is as short as 1 minute to completely melt it. This is a relatively low temperature for a compound containing zircon with a high melting point, and is one of the effects of the present invention. The cause of this is
This is because all the raw materials have been melted once, and the steelmaking slag acts as a melting agent. Therefore, zircon is homogeneously distributed in the melted raw materials, so its content is relatively small. The improvement in cement alkalinity resistance is remarkable.

ick) is a refractory that has recently been used for glass fiber melting furnaces, and its physical properties and composition are as follows: Zircon (ZrSiO4) exists as a silicate, and this is used in soda lime silicate for window glass and iron manufacturing. This is thought to be due to the compatibility of slag with calcium silicate, which causes them to dissolve homogeneously, resulting in the formation of an orderly molecular arrangement of glass fibers. Window glass scrap is glass mainly composed of soda-lime silicate, and its composition is approximately in the following composition range (wt%):
