    • PURPOSE: A production method of a glass substrate is provided to control the curving or breaking of a transfer pipe and a refining pipe by contacting the expanded transfer pipe to a melting furnace and the refining pipe. CONSTITUTION: A production method is conducted in a melting furnace (101), a transfer pipe, and a refining pipe (102). The production method comprises the following steps before producing molten glass: heating the transfer pipe formed of platinum or an platinum alloy; and contacting one end of the transfer pipe with an end (101b) of the melting furnace, and contacting the other end of the transfer pipe with an end (102b) of the refining pipe. Each end of the melting furnace, the transfer pipe, and the refining pipe are cooled from the outside of the pipe. The molten glass is cooled and coagulated by the ends, and forms a flow path.
    • 目的:提供一种玻璃基板的制造方法,用于通过使膨胀转移管与熔化炉和精炼管接触来控制输送管和精炼管的弯曲或断裂。 构成:在熔炉(101),输送管和精炼管(102)中进行制造方法。 该制造方法在制造熔融玻璃之前包括以下步骤:加热由铂或铂合金形成的传输管; 并且将所述输送管的一端与所述熔化炉的端部(101b)接触,并且将所述输送管的另一端与所述精炼管的端部(102b)接触。 熔融炉,输送管和精炼管的两端从管的外部冷却。 熔融玻璃被冷却并通过端部凝结,形成流路。

    • This method for manufacturing a glass plate includes a melting step, a fining step, and a forming step. In the melting step, molten glass is produced by using at least electrical heating to melt a glass feedstock containing SnO2 as a fining agent. The fining step includes the following: a bubble-removal process in which the temperature of the molten glass is raised to at least 1,630°C so as to generate bubbles therein in order to perform bubble removal; and an absorption process, after the bubble-removal process, in which the temperature of the molten glass is reduced at a rate of at least 2°C/min over the temperature range from 1,600°C to 1,500°C so as to make the molten glass absorb the bubbles therein. In the forming step, a down-draw process is used to form the post-fining-step molten glass into plate glass.
    • 该制造玻璃板的方法包括熔融步骤,澄清步骤和形成步骤。 在熔融步骤中,通过至少使用电加热来熔融含有SnO 2作为澄清剂的玻璃原料来生产熔融玻璃。 澄清步骤包括:将熔融玻璃的温度升高至至少1630℃以在其中产生气泡以进行气泡去除的气泡去除过程; 以及在气泡去除过程之后的吸收过程,其中熔融玻璃的温度在1,600℃至1,500℃的温度范围内以至少2℃/ min的速率降低,以便 使熔融玻璃吸收其中的气泡。 在成型步骤中,使用下拉法将后澄清步骤的熔融玻璃形成为平板玻璃。
