| description | The present invention relates to a waste SiC powder briquetting method and a briquette additive for casting obtained by the same. According to the present invention, waste SiC powder generated from silicon wafer sludge can be subjected to briquetting such that the powder is given strength and density suitable for use as a casting additive that can be easily transported and stored and has a high yield. The present invention includes: a step in which SiC powder is collected from silicon sludge resulting from a silicon wafer cutting process; a step in which Fe powder is added as a binder for the SiC powder; a step in which article molding is performed by pressure being added to the SiC-Fe mixed powder; and a step in which the molded article obtained in the preceding step is sintered.
폐 SiC 분말의 단광화 방법 및 그에 의한 주물용 단광 첨가제에 관한 것으로, 실리콘 웨이퍼 슬러지에서 폐기물로 발생된 SiC 분말을 이송 및 보관하기 용이하고 높은 수율을 갖는 주물 첨가제로 사용하는데 적당한 강도 및 밀도를 갖도록 단광화하는 것이 가능한 것이다. 이러한 본 발명은, 실리콘 웨이퍼 절단 공정에서 발생하는 실리콘 슬러지로부터 SiC 분말을 수거하는 단계와; 상기 SiC 분말의 결합제로서 Fe 분말을 첨가하는 단계와; 상기 SiC 분말에 상기 Fe 분말이 첨가된 혼합분말에 압력을 가해 성형체로 성형하는 단계와; 전 단계에서 성형된 성형체를 소결하는 단계를 포함하는 것을 특징으로 한다. |
