#AskGlaston Flat Tempering Series #6: How to avoid the loading delays in tempering?

In this sixth episode of #AskGlaston flat tempering series, we explore how to avoid loading delays in tempering.

Loading delays occur when the furnace isn’t ready to receive the next glass batch from the loading table. This is often caused by temperature fluctuations inside the furnace. When the temperature is inconsistent, glass heating becomes suboptimal, and the next batch must wait until conditions stabilize.

Glaston’s Roller Heat Control (RHC) system addresses this challenge by continuously measuring the roller temperature directly from the rollers and automatically adjusting the heating to maintain optimal levels. This ensures a more stable and uniform temperature throughout the furnace, making furnace operation much easier.

In addition to improving process consistency and glass quality by reducing surface defects and manual adjustments, Roller Heat Control also significantly enhances energy efficiency. By minimizing temperature fluctuations, the system reduces unnecessary reheating and idle time, thereby lowering overall energy consumption. Faster, more consistent loading means the furnace operates more efficiently, with less energy wasted during waiting periods.

Roller Heat Control improves the efficiency, quality, and energy performance of the tempering process by stabilizing furnace temperatures, minimizing loading delays, and optimizing energy use.
