Solid phase separation from molten slag

本研究的目的是减少炼钢渣特别是脱磷渣的用量，并从渣中回收有价磷。当排出时，脱磷渣作为富磷固相与含有FeO的基质液相一起存在。针对这些特点，采用离心分离机与电炉相结合的方法对熔融脱磷渣进行了离心分离实验。因此，大多数富磷固相积聚在所获得的低碱度炉渣的上层。

The purpose of this study is to reduce the amount of steelmaking slag, especially dephosphorization slag, and to recover valuable phosphorus from the slag. When discharged, the dephosphorization slag exists as phosphorous-enriched solid phases together with matrix liquid phases containing FeO. Because of these characteristics, centrifugation experiments of molten dephosphorization slag were carried out using a centrifugal separator combined with an electric furnace. Consequently, most of the phosphorous-enriched solid phases accumulated in the upper layer of the obtained low-basicity slag.
