Abstract

In the firing stage, the final stage of ceramic production process, various types of kiln are used. In recent times, the electric kilns, of which heat source is electricity, are being used easily and widely in numerous industrial sites and small-scale workshops. The use of electric kilns has made the production process simplified unimaginably comparing with firewood kilns in the past, of which heat source was firewood and so on, consequently the opportunity has been given to develop in the overall aspects of the foundation of ceramic production through the aspect of serviceability related to firing and the increased success rate of products after firing. As the operating principle of electric kilns is that the heat is being generated by conducting electric currents to the heating element being installed inside a kiln, the electric kilns are using a nichrome wire based on nickel and chromium, a more durable heating element of silicon oxide or Kanthal wire, a plutinum wire, and so on, as the heating elements. The electromagnetic wave is an electromagnetic energy being generated from the conducts of electricity and magnetism, and so it is being generated wherever electricity conducts, thus the electromagnetic wave is also being generated in the electric kiln using the principle of heating action through electric currents. People today are exposed inevitably to excessive electromagnetic waves at homes, workplace, and surrounding environment, therefore the controversies on the harms of electromagnetic waves being exposed to non-defensive people become very important issues recently. Thus, this study measured and analyzed the burst size of electromagnetic wave being generated during the firing of electric kiln, which is the final stage of ceramic production process, according to each temperature change, after setting distances between the targeted kiln and a measuring device into five sections. Consequently, the purpose of this study is to protect people's bodies from the dangers, possibly happening during firing works, by imprinting and warning the harms of electromagnetic waves to numerous ceramic workers in production sites through this investigation.
