GLASS MANUFACTURING APPARATUS AND METHODS

A method of controlling a flowrate of molten material (121) at a downstream location (203) in a glass manufacturing process (100) comprises forming a glass ribbon (103) from the molten material (121) at the flowrate; calculating the flowrate of the molten material (121) from which the glass ribbon (...

Zusammenfassung:	A method of controlling a flowrate of molten material (121) at a downstream location (203) in a glass manufacturing process (100) comprises forming a glass ribbon (103) from the molten material (121) at the flowrate; calculating the flowrate of the molten material (121) from which the glass ribbon (103) was formed; calculating a viscosity of the molten material (121) at an upstream location (201) positioned upstream from the downstream location (203) relative to a flow direction of the molten material (121); estimating the flowrate based on the calculated viscosity and the calculated flowrate; and controlling the flowrate of the molten material (121) at the downstream location (203) based on the estimated flowrate.
