MANUFACTURING METHOD FOR HIGH-HEAT-RESISTANT NOZZLES AND HIGH-HEAT-RESISTANT NOZZLES MANUFACTURED BY THE SAME
A method for manufacturing a highly heat-resistant nozzle according to one embodiment of the present invention includes a step of manufacturing a mold; a sludge injection step of injecting sludge into the mold; a precursor formation step of firstly heating the mold filled with the sludge in a high temperature furnace to burn the mold, and preliminary heating the sludge to form a precursor; an impregnation step of immersing the precursor in an aqueous solution containing a highly heat-resistant material and then heating the same to absorb the heat-resistant material on the surface of the precursor; and a nozzle manufacturing step of manufacturing a nozzle by secondary heating the precursor having the heat-resistant material absorbed on the surface thereof in a high-temperature furnace. According to the present invention, the production cost of the nozzle can be reduced.
본 발명의 일 실시예에 따른 고내열성 노즐 제작 방법은 몰드를 제작하는 단계; 상기 몰드에 슬러지를 주입하는 슬러지 주입 단계; 상기 슬러지가 충진된 몰드를 고온의 노에서 1차 가열함으로써 상기 몰드를 연소시키고, 상기 슬러지를 초벌 가열하여 전구체를 형성하는 전구체 형성 단계; 상기 전구체를 고내열성 물질을 포함하는 수용액에 담지한 후 가열하여, 상기 전구체의 표면에 상기 내열성 물질을 흡수시키는 함침 단계; 및 내열성 물질이 표면에 흡수된 상기 전구체를 고온의 노에서 2차 가열함으로써 노즐을 제작하는 노즐 제작 단계;를 포함할 수 있다.
