Ring tray for honeycomb substrate firing

Abstract

A ring tray for honeycomb substrate firing, the ring tray supporting a honeycomb substrate having cell flow channels partitioned by cell walls, so that the flow channel direction is vertical during substrate firing, the ring tray including a ring-shaped frame part, a support part further inside than the frame part, and a connecting part connecting the frame part and support part, and the ring tray being configured so that when the honeycomb substrate is mounted on the ring tray, the support part does not contact an outer peripheral edge of a lower end surface of the honeycomb substrate, and contacts a portion of an internal region of the lower end surface of the honeycomb substrate, and is thus able to support the lower end of the honeycomb substrate, and the frame part and the connecting part do not contact the lower end surface of the honeycomb substrate.
