Summary:To provide a glass wool made of glass fibers having fiber tensile strength of 900 MPa or more.SOLUTION: A method for manufacturing a glass wool made of glass fibers having fiber tensile strength of 900 MPa or more includes: a step of introducing molten glass to a spinner; a step of injecting the molten glass from a small hole on a side wall of the spinner by rotating the spinner; a step of jetting combustion gas to the injected molten glass; and a step of spraying compressed air to the molten glass after contacting the combustion gas from an air ring compressed air blowout port arranged on an outer side of a rotational axis of the spinner than the combustion gas blowout port.SELECTED DRAWING: Figure 1 【課題】繊維引張強度が９００ＭＰａ以上であるガラス繊維から構成される、グラスウールを提供することを目的とする。【解決手段】繊維引張強度が９００ＭＰａ以上であるガラス繊維から構成される、グラスウールの製造方法であって、スピナに溶融ガラスを導入する工程と、スピナを回転させることにより、前記スピナの側壁の小孔から溶融ガラスを射出する工程と、燃焼ガス吹き出し口から、前記射出した溶融ガラスに燃焼ガスを噴出する工程と、スピナの回転軸に対して前記燃焼ガス吹き出し口よりも外側に配置されるエアリング圧縮空気吹き出し口から、燃焼ガスに接触した後の溶融ガラスに圧縮空気を吹き付ける工程とを含む、グラスウールの製造方法。【選択図】図１
