The Dynamics of Ceramic Rollers and Operating and Maintenance Practices to Produce Quality Tempered Glass

Renald D. Bartoe

Heat treating glass in horizontal tempering furnaces is a dynamic process influenced by the systems, controls, and engineering quality of the furnace. Additionally, the quality and stability of the ceramic furnace rollers, maintenance programs, plant cleanliness, and glass fabricating practices are critical and significant to glass quality and productivity. The introduction of new value-added and high performance glass coupled with new and tighter glass specifications requires comprehensive understanding and strict control of the tempering process. This includes the proper use and maintenance of precision fused silica ceramic rollers.
