Alumina-based spark plug insulators have traditionally been sintered in continuous gas-fired car tunnel kilns with cycle times of thirty to forty hours. Automation of the handling has been difficult, and large amounts of kiln furniture are required to hold the ware as it passes through the kiln. This report describes an electric alternative that drastically shortens the firing cycle while maintaining desired ceramic properties. A fast-fire, electrically-heated, continuous kiln design is proposed which minimizes kiln furniture and promotes automated handling of the insulators.
