Abstract

The floatation of oxide inclusions in static liquid iron was studied using the complex deoxidizez, calcium-silicide.<BR>The obtained results are as follows;<BR>1) At the initial stage of reaction, oxygen content in liquid iron decreases rapidly, but at the next stage of reaction decreases slowly, when the melt was deoxidized by calcium-silicide addition.<BR>2) Deoxidation products become large during short time but the rate of floatation of fine particles are so slow that the cleanliness of liquid iron is not good.<BR>3) The rate of floatation of large oxide particler is greates than that of deoxidation products by metallic silicon.
