Abstract

A new method for controlling the BOF process is proposed thatinvolves the use of an original in blow heterogeneous sampler and adedicated laser analytical method. The aim is to deliver a fast andcomprehensive analysis of steel and slag collected by the heterogeneous-samplings. Combined with a metallurgical model, the dataobtained with the heterogeneous samples make it possible to dynamicallyassess the refining progress in order to allow a safe directtapping practice.
