イ）必要がある。In general, in a continuous plate glass melting kiln, a homogeneous glass base with few bubbles is produced from the glass base f-1.
'The temperature of the glass substrate in the tank is 1500-1550℃.
need to be raised to. On the other hand, when forming a molten glass base into various types of plate glass, the temperature of the glass base is 11:1 - In the case of the float type plate glass manufacturing method, the temperature of the glass base is 11:1.
00-1200°C. Therefore, when transferring the glass substrate from the melting tank to the molding section, it is necessary to lower the temperature of the glass substrate.

ずれも問題イぐイ１し７ている。Conventionally, as a means for this purpose, a clarification tank is provided in succession to the melting tank, and the glass substrate is cooled by natural heat radiation from the top, bottom, and side surfaces of the clarification tank. A means of indirectly cooling the glass substrate by providing a tunnel-shaped glass substrate passage called a throat and cooling the bricks that make up the throat with air. A water-cooled cooler called a floater is immersed in the glass substrate. Various methods have been proposed, such as cooling the glass substrate by blowing cooling air into a clear tank or working tank, but all of them cool the glass substrate by conduction or convection. Since cooling is performed, there are no problems in either case.

面で大ぎな無駄がある。For example, 1, 'l+';7f> When using natural heat radiation in a tank, a wide heat radiation surface 4.
When the clarification tank itself becomes larger and when cooling air is blown into the clarification tank, etc., the thermal conductivity of glass is low, so only the surface layer of the glass substrate may be cooled and a skin may form. However, since the viscosity of the non-glass base increases greatly when the temperature drops, it is not possible to create a uniform flow as a whole, with only the high temperature base flowing in the center part of the flow of the glass base as flow A1. Furthermore, in the conventional cooling means, since the waste heat generated by cooling the glass 7 is not so high, it cannot be reused, resulting in a large waste in terms of thermal efficiency.
