06 Mar 2006TL;DR: In this paper, an initial pre-firing step whereby the green core is located through a stem 1 a in an initial partial depth 5 of firing media 4 in the tube or containment 2 until it achieves a sufficient mechanical strength to enable positional adjustment is described.
Abstract: Firing of ceramic cores ( 1 ) is important in order to achieve manufacturing processes. These ceramic cores ( 1 ) are generally formed in a “green” state which has limited mechanical strength and may be distorted during the firing process by non-uniform thermal effects, etc. By providing a tube or containment 2 which is located on a saggar base 3 and surrounded by firing media 4 , it is possible to achieve an initial pre-firing step whereby the “green” state core 1 is located through a stem 1 a in an initial partial depth 5 of firing media 4 in the tube or containment 2 until it achieves a sufficient mechanical strength to enable positional adjustment. Thus, the green core will be pre-fired in a kiln solely supported through the stem 1 a and then the core adjusted using a tool such as an engineering rule. There is a positional accuracy between the walls of the tube or containment 2 and the saggar base 3 between all cores and then the tubes 2 filled and leveled with further firing media 4 for the main firing of the core 1 in use.

Thus, the green core will be prefired in a kiln solely supported through the stem la and then the core adjusted using a tool such as an engineering rule. There is a positional accuracy between the walls of the tube or containment 2 and the saggar base 3 between all cores and then the tubes 2 filled and leveled with further firing media 4 for the main firing of the core 1 in use.
