CONVERGENCE CHECK OF DATA FROM STEP-BY-STEP EXPERIMENTAL-COMPUTATIONAL MAGNETIC CONTROL OF IRON IMPURITIES IN RAW MATERIALS USING DIFFERENT FIELD SOURCES

摘要

The mass-operational characteristics of magnetic control of iron impurities in raw materials (silica sand, feldspar, gypsum), following an exponential law both fully and partially (tail section), when an experimental-computational model of control of iron impurities is possible taking account of the appropriate corrections, are analyzed. It is shown for different sources of the field that the results of magnetic control performed with a limited number of operations differ considerably between one another while for an unlimited number of operations (operational-computational method) they remain practically identical even though the form of the mass-operational characteristic changes.
