摘要： The subject matter of this invention relates to an improved method for controlling an industrial glass fiber-forming process. More particularly, it involves a method for controlling the thermal environment of several fiber glass bushing assemblies by the utilization of fin cooler assemblies in which a coolant is passed through the fins as part of a closed-loop pressurized system to remove heat radiated to the fins by the molten glass that emerges from the bushing. In the preferred embodiment, this liquid coolant is demineralized water operating at a pressure of somewhere between 18 and 100 psi.The use of a programmable logic controller to monitor various system parameters such a pressure, temperature and flow rate is also disclosed. The controller is programmed to take corrective action automatically upon the detection of certain triggering events in order to maintain a constant flow of coolant throughout the entire system. As a last resort, means are provided for injecting an emergency supply of cooling water to continuously flush the system and prevent mechanical distortion and possible rupturing of the fins.
