Description

복합내화제품 제조방법Manufacturing method of composite refractory products

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명에 의해 복합 밸브 플레이트를 제조하기 위한 1차 성형 조작 및 그 장치. 제2도는 복합밸브 플레이트를 완결시키기 위한 2차 성형조작 및 그 장치.1 is a primary forming operation and apparatus for producing a composite valve plate according to the present invention. 2 is a secondary forming operation and a device for completing a composite valve plate.

Claims (1)

컵 모양 금속박과 그 짝으로부터 1차 모울드공간을 만들어 표면부분의 반대쪽 모양을 한 영구 모울드 요소를 구성하고, 1차 모울드 공간에 성형이 되는 내화 콩크리트를 채우고 최소한 부분적으로 이 콩크리트를 경화시키고, 금속박을 조립하여 짝 모울드 요소로부터 형성된 2차 모울드 공간에서 성형하며, 1차 콩크리트보다 성능이 작은 2차 내화 콩크리트를 2차 모울드 공간을 채우고 이 콩크리트를 경화시킨후 완전히 경화되지 않을 정도로 1차 콩크리트도 경화시키므로서 용융금속유동과 접촉하는 표면부분을 가진 내화제품의 제조방법.From the cup-shaped metal foil and its mating, a primary mold space is formed to form a permanent mold element with the shape opposite to the surface part, and the primary mold space is filled with refractory concrete to be molded and at least partially cured. It is assembled and molded in the secondary mold space formed from the mating mold element, and the secondary refractory concrete, which is smaller than the primary concrete, is filled in the secondary mold space, and the primary concrete is also hardened to the extent that it is not completely cured after curing the concrete. Process for the manufacture of refractory products having surface portions in contact with molten metal flow. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
