In the process of smelting, the calculation of electrode consumption has two concepts: net consumption and gross consumption (ore-bearing hot furnace).Net consumption means that the hand consumption of the technical water pump in which the electrode is sublimated, oxidized and reacted by high temperature is the sum of the net consumption and the loss before taking part in smelting.At present, the iron and steel industry uses hand consumption to evaluate the physical quality of graphite electrodes.
1.Yield method
The production method is based on the amount of steel water (finished product) produced in a certain period, and the consumption is based on the input amount of graphite electrode in the same period minus the remaining amount on the furnace.
Gross consumption of graphite electrode per ton steel: MM=MZ/MG.
Net consumption of graphite electrode per ton steel: MJ=MC/MG.
Where: MZ is the total consumption of the electrode (input-residual amount on the furnace), KG/T:
MC is the net consumption of the electrode (input-residual loss on the furnace), KG/T.
MG is the finished product of molten steel, T.
2.Power consumption method
The power consumption method is based on the accumulative amount of power consumption of pure heating time in a certain period, and the consumption is calculated by deducting the residual amount of graphite electrode from the furnace in the same period (the power consumption of LF furnace is calculated by the power consumption and electrode per heating temperature 1 ℃).
Electrode consumption per kilowatt-hour:
MX=1000*MC/QH.
Among them: MC is the net consumption of electrode (input-furnace residual-loss) KG/T:QH is the cumulative amount of power consumption in pure heating time, KW*H.
