Title:
FLOAT GLASS MANUFACTURING METHOD AND FLOAT GLASS MANUFACTURING APPARATUS
Document Type and Number:
Japanese Patent JP2015134690
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a float glass manufacturing method capable of reducing a temperature variation width at a plurality of positions of a lower wall part of a bathtub at the same time.SOLUTION: There is provided a float glass manufacturing method including a molding process of molding a plate-like glass ribbon by letting molten glass G flow over molten metal M in a bathtub 11. In the molding process, a lower wall part of the bathtub 11 is cooled by blowing a fluid to a lower surface of the bathtub 11 through a main pipe 31, a branch pipe 32, and a nozzle 33, a flow rate adjustment part 35 which adjusts the flow rate of the fluid is provided halfway in each branch pipe 32, the lower wall part has a plurality of temperature adjustment regions for adjusting the temperature independently by the plurality of flow rate adjustment parts 35, and at least one temperature sensor 20 is provided in each temperature adjustment region. In the molding process, each flow rate adjustment part 35 is controlled based upon a measured temperature of at least one temperature sensor 20 provided in the corresponding temperature adjustment region.
