METHOD FOR CONTROLLING PHOSPHORUS PRODUCTION PROCESS IN ELECTROTHERMIC FURNACE Russian patent published in 1997 - IPC

Abstract RU 2081818 C1

FIELD: electrothermics. SUBSTANCE: electrical and process parameters of operating furnace are maintained by introducing adjustments into reductant doses with due consideration for relationship existing between P₂O₅ content in slag and electrical parameters. Proposed method also takes into account errors in metering-out other components, i.e. phosphorite and quartzite, and eliminates effect of transition process taking place along "feedstock-slag" path. EFFECT: method offers greater flexibility in controlling phosphorus production process. 1 tbl, 1 dwg
