Apparatus and method for manufacturing float glass

Abstract

An apparatus for manufacturing a float glass includes a bottom block in which molten metal is stored to float, a loop block which covers the bottom block, and a plurality of thermocouples buried in the loop block in a predetermined pattern to measure the temperature of the loop block so that a temperature gradient of an inner circumstance of a float chamber formed by the bottom block and the loop block is measured and / or controlled.

Description

[0001] Cross-references to related applications [0002] Pursuant to Title 35, United States Code, Section 119(a), this application claims priority to Korean Patent Application No. 10-2010-0051988 filed with the Korean Intellectual Property Office on June 1, 2010, which is hereby incorporated by reference in its entirety at In this application. technical field [0003] The present invention relates to an apparatus and method for manufacturing float glass, and more particularly to an apparatus and method for manufacturing float glass having an improved structure such that the status to more precisely check the operating conditions of the float tank (e.g. temperature gradients in the float tank) to consistently maintain the quality of the glass ribbon produced. Background technique [0004] In general, flat glass used in industry (eg panes for vehicles or buildings etc., eg soda lime silicate glass) is mostly produced using the float process well known in the art. In additio...

AI Technical Summary

Problems solved by technology

[0006] However, when directly checking the temperature of the molten metal by immersing a thermocouple in the molten metal or directly checking the temperature of the glass ribbon with a pyrometer, there are many conditions such as restrictions on the measurement position

Thus, it is impossible to detect changes in the operating conditions of the pontoon and consistently maintain the quality of the formed molten glass (e.g., overall variation in the thickness of the molten glass)
