Abstract: The present invention provides a high-modulus glass fiber composition, a glass fiber and a composite material therefrom. The glass fiber composition comprises the following components expressed as percentage by weight: 55-64% SiO2, 13-24% Al2O3, 0.1-6% Y2O3, 3.4-10.9% CaO, 8-14% MgO, lower than 22% CaO+MgO+SrO, lower than 2% Li2O+Na2O+K2O, lower than 2% TiO2, lower than 1.5% Fe2O3, 0-1.2% La2O3, wherein the range of the weight percentage ratio C1=(Li2O+Na2O+K2O)/(Y2O3+La2O3) is greater than 0.26. Said composition can significantly increase the glass elastic modulus, effectively inhibit the crystallization tendency of glass, decrease the liquidus temperature, secure a desirable temperature range (ΔT) for fiber formation and enhance the fining of molten glass, thus making it particularly suitable for production of high-modulus glass fiber with refractory-lined furnaces.

Abstract: A method for heating a liquid glass channel of a glass fiber tank furnace. The method comprises: passing oxygen gas and a fuel, via a burner (1), into a channel space (3) for combustion to heat the channel space (3) and a liquid glass (2), wherein the flow rate of the fuel is VF and the flow rate of the oxygen gas is VOX such that the relative velocity difference D=(VF−VOX)/VF. The temperature of the channel is 0-1500° C., and the relative velocity difference D is kept to 25% or more. A pure oxygen combustion method is used for heating a tank furnace channel to reduce waste gas emission and heat loss, thereby achieving the goals of energy conservation, reduced carbon emissions, and improve environment friendliness. The fuel flow rate, relative velocity difference, and related parameters can be controlled according to the temperature of the channel, providing excellent uniformity and accurate control of the temperature of the channel.
