SUMMARY

The discussion focuses on selecting the appropriate heating element for a kiln designed to reach temperatures of 1200°C, utilizing refractory materials capable of withstanding 1500°C. Key considerations include the wattage of the heating element and the integration of a PID controller for precise temperature management. Participants emphasize the importance of understanding heat retention and radiation from the kiln's refractory walls to maintain desired temperatures without damaging the heating elements.

PREREQUISITES
  • Understanding of kiln construction and refractory materials
  • Knowledge of PID controllers and their application in temperature regulation
  • Familiarity with heating element specifications and wattage calculations
  • Basic principles of heat transfer and thermal radiation
NEXT STEPS
  • Research "PID controller setup for kiln temperature control"
  • Explore "types of heating elements for high-temperature kilns"
  • Learn about "heat retention in refractory materials"
  • Investigate "wattage requirements for ceramic kilns"
USEFUL FOR

Pottery enthusiasts, kiln builders, ceramic artists, and anyone involved in high-temperature firing processes will benefit from this discussion.

Hello Everyone,

I've been looking for an answer to problem I have and I'm getting nowhere so I thought asking the question in a place like this might be useful.

I'm planning to build a kiln. I have refractory material that can sustain 1500 degrees celsius. I'm trying to choose an element but I don't understand heat that well.

If I put any element (of reasonable wattage) in their at full power will the inside of the kiln continually get hotter and eventually get to a high temp?

How should I choose an element (I will be putting a PID controller on it by the way) - I want to get heats of up to 1200 degrees celsius.

Does the heat from the element get stored and re-readiated fromt he refractory/walls?

Do heating elements get hot enough that they can melt/destroy themselves?

Thanks in advance,

Maya
