MANUFACTURING METHOD OF THE CERAMIC CORE ON THE GAS TURBINE HOT COMPONENTS DURING SINTERING AND SUPPORT PLATE FOR SINTERING OF CERAMIC CORE

摘要

PURPOSE: A manufacturing method of ceramic core for gas turbine high temperature manufacturing and a supporting plate for the core for gas turbine high temperature manufacturing are provided to prevent the breaking of the ceramic cores. CONSTITUTION: A manufacturing method of ceramic core for gas turbine high temperature manufacturing comprises the following steps: manufacturing a ceramic core(1) by injecting a ceramic mixture into a space inside of a mold for ceramic core manufacturing(2); settling the ceramic core to a core seating groove portion(11) of a core supporting panel member(10) and inserting the core supporting panel member into a sintering furnace(3); and covering the upper part of the core supporting panel member and the ceramic core with sintered powder inside the sintering furnace. A supporting plate for sintering of the ceramic core for gas turbine high temperature components manufacturing includes the core supporting panel member. On the upper surface of the core supporting panel member, a core seating groove part is formed. The core seating groove part has a shape corresponding to the shape of the ceramic core.
