METHOD OF AUTOMATIC CONTROL OF CHARGE PALLETIZING PROCESS Russian patent published in 2003 - IPC

FIELD: ferrous metallurgy; control of iron ore palletizing processes. SUBSTANCE: proposed method includes measurement of mass of charge fed to palletizer, measurement of power of palletizer engine and revolutions of palletizer. Proposed method includes additionally specific power at palletizer as the quotient of division of power consumed by palletizer engine related to mass of charge fed to palletizer; this magnitude is stored and unit impulse for increase of revolutions of palletizer engine is furnished; after transient period, power is again measured and new magnitude of specific power is calculated ; in case deviation thus found is positive, unit impulse is again furnished to converter for increase of palletizer engine revolutions and procedure is repeated till sign of difference between subsequent and previous magnitudes is reversed. When this sign is reversed, unit impulse is furnished for decrease of palletizer engine revolutions. EFFECT: possibility of control of sinter cake strength due to revealing parameters having effect on its strength. 5 dwg, 3 tbl
