铸造用铬铁矿砂的可选性研究

Separability of Chromite Sand for Foundry

研究了铬铁矿砂在不同的温度加热后的单位质量磁化率变化趋势;通过强磁场磁选机分选树脂混合砂,分选率达到85.6%。证明铬铁矿砂具有可选性。

The changing tendency of the magnetic susceptibility per unit mass for chromite sand was studied after heated at different temperatures. By using of the high intensity magnetic separator for the mixture of resin bonded sand and chromite sand, it was found that the separating rate of chromite sand can reach to 85.6%, which testifies that the chromite sand can be magnetic separated.
