Title: Treatment of molding sand
Inventor: UCHIMURA KATSUJI
IPC: B22C5/18
Filed: 1983-09-16
Abstract: PURPOSE:To recondition molding sand having a stable characteristic in short time by calculating the necessary rate of secondary water spraying from the correlation with the known moisture content at the point of time when the compactability value of sand after primary water spraying stops increasing, then spraying water to the sand. CONSTITUTION:The compactability and moisture content of sand are important for regenerating recovered sand to molding sand and have a strong correlation with each other. The rate of primary water spraying is determined as a difference between the moisture content of the recovered sand and the target moisture content but the necessary compactability is not enough. The sand is kneaded after the primary water spraying and the moisture and compactability are successively measured. The target rate of secondary water spraying is calculated by utilizing the predetermined correlation between both measured values and the water spraying is performed at the point of time when the compactability stops increasing. Just two times of water spraying operations are required according to such method and the molding sand having a stable characteristic is reconditioned in short time.
