The Significance of Attaining Uniform Cooling
When kilnforming glass, particularly largescale work, you will need to cool the glass uniformly all through the annealing vary. The temperature distinction throughout the glass—from prime to backside, facet to facet, or finish to finish—needs to be no better than 10ºF (5ºC). Such uniformity prevents numerous issues, together with the creation of annealing pressure, which might result in glass failure.
At Bullseye, to make sure uniform cooling and correct annealing of large-scale work, we monitor temperatures at a number of factors throughout the kiln throughout firing.
Our multiple-point temperature monitoring system includes using thermocouples and a pyrometer. The pyrometer shows temperatures which might be sensed by the thermocouples, that are positioned at two or extra places throughout the kiln. (Determine 1)
Info gathered and displayed by the pyrometer signifies how the glass and the kiln are heating and cooling and whether or not kiln temperatures must be modified to forestall annealing pressure—both by adjusting warmth output from the highest, backside, or facet parts (if they’re managed individually) or by slowing the cooling price. A multiple-point temperature monitoring system is nicely well worth the small funding in gear and vitality required for set up.
On this doc, we talk about when to make use of such a system, the gear that’s wanted, the place to seek out the gear, learn how to set up it, and learn how to use the data gathered to assist guarantee profitable annealing.
