Abstract

Under considering the interaction of the factors, the effects of the clay content, moisture content and coal content on the compactibility, permeability, green compressive strength and shatter index of green sand for high density moulding have been studied according to the orthogonal experimental method. The experimental results lead to the following conclusions. The optimal combination is that the clay content is 8%, the moisture content is 3.2% and the coal content is 5%. The moisture content is the strongest factor affecting the compactibility and permeability. The clay content is the most significant factor affecting the green compressive strength and shatter index. The interaction between the clay content and moisture content has key effect on the permeability, green compressive strength and shatter index, so the optimal ration of the clay content and the moisture content must be achieved. The effect of the coal content on the permeability, green compressive strength and shatter index is too less than that of the clay content and moisture content.
