Abstract

  The oolitics formation of green sand is a significant composition which effects the sand property greatly. However the oolitics mechanism has not yet been clarified. Therefore in this study, we made green sand, burnt it to 1473K, peeled off the oolitics which had adhered using a rammer, and observed the mechanism of oolitics formation. The results showed that oolitics adhered at 873K are easy to peel off and those over 1073K are difficult. The results also showed that the CO₂ process core sand increases oolitics and the core sand using organic binder decreases the formation of oolitics.
