Description

고품질 알루미나 시멘트의 제조방법Manufacturing method of high quality alumina cement

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

제1도는 본 발명에 따른 고품질 알루미나 시멘트의 개략 제조 공정도.1 is a schematic manufacturing process diagram of a high quality alumina cement according to the present invention.

Claims (3)

알루미나 시멘트를 제조하는데 있어서, 동일온도범위(1100-1400℃)에서 두 단계의 소성(일차소성, 이차소성)을 거쳐 알루미나 함량이 80-90%가 됨을 특징으로 하는 고품질 알루미나 시멘트의 제조방법.A method for producing high quality alumina cement, characterized in that the alumina content is 80-90% through two steps of firing (primary firing and secondary firing) in the same temperature range (1100-1400 ° C.). 제1항에 있어서, 일차소성은 1200-1400℃의 온도에서 실시하고 생성된 1차 클린커를 20-50℃의 습기함에서 수화반응시켜 비표면적을 20,000-30,000㎠/g로 증대시킴을 특징으로 하는 고품질 알루미나 시멘트의 제조방법.The method of claim 1, wherein the primary firing is carried out at a temperature of 1200-1400 ℃ and hydration reaction of the resulting primary clinker in the moisture of 20-50 ℃ to increase the specific surface area to 20,000-30,000 cm2 / g Process for producing high quality alumina cement 제1항에 있어서, 이차소성은 1000-1300℃온도에서 실시하여 활성이 높은 CaO, 2Al2O3성분의 클린커를 쉽게 합성함을 특징으로 하는 고품질 알루미나 시멘트의 제조방법.The method of claim 1, wherein the secondary firing is carried out at a temperature of 1000-1300 ° C. to easily synthesize a highly active CaO and 2Al 2 O 3 component clinker. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
