PROCEDIMIENTO Y SISTEMA PARA VERIFICAR LA CONVERSION DE MI- NERAL DE HIERRO EN NODULOS DE ALTO CONTENIDO EN HIERRO.

摘要

Apparatus and method for monitoring selected samples in situ in an iron ore converter the stages of reduction of the ore into iron sponge pellets having a desired iron content. The apparatus comprises a series of induction coils encircling the converter. The coils are coupled to an R F Circuit which is coupled to a meter which indicates the inductance values correlated with the iron content of the measured sample and its temperature thus providing indicia of the stage of conversion of the ore.
