output. Self baked carbon electrodes are immersed in the furnace which are hung
from the top and operated by a hydraulic system. These electrodes are connected
to the transformer through a copper bus bar. The electrodes produce necessary
electric arc in the furnace shell which helps in the oxidation of ores using fluxes
& carbon. The metal and slag are taped at regular intervals and collected in
pans/moulds.
Main Receiving Control Room
“Main Receiving Control cubical” is placed in this room to receive power
Generated in the Power Plant. It consists of Current Transformer, Potential
Transformer for metering and protection of the equipment and various electrical
controls. It also consists circuit breakers to switch on and off the circuit and also
to trip under fault conditions. Power is distributed to various places of plant
from this control room.
Raw material Day Bins:
The raw materials are first stored in day bins. The capacity of the day bins are
such that they cater the daily demand of raw material for the furnace. The
materials are then transferred to the furnace in specified quantities or batch
through a skip hoist system. The batches are controlled by an Electronic batch
weighing system.
Material conveying system:
The raw materials are first dumped in a ground hopper and then conveyed to the
day bins by a belt conveyor. The batch discharged by the batch weighing system
is conveyed to the charging bins which are located around and above the
