system as per Automation Configuration Diagram
(MEC/S/9101/11/E9/55/01/064.02/R1).
In the new Automation system, provision will be kept for interfacing
employer’s PLC and /or Remote I/O stations for all source and
destination conveyors.
05. Augmentation in Flux - Fuel Preparation and Plant Return Fines
Handling for SP III- Control, Monitoring, Interlocking and Sequential
functions of new drives and equipment proposed for Augmentation of
Flux and Fuel crushing and screening circuit as described below in line
with material flow diagram:
i. Feeding of coke breeze from coke breeze bunker of coke sorting
plant(CSP4) to existing conveyor C102
ii. BF fines from existing BFs through conveyor C7, new conveyor
C3A-C1 to existing Conveyor F101 in junction house JH 127.
iii. Feeding of sinter /ore fines from BF8 fines storage bins to existing
conveyor F101 in junction house JH 127
iv. Feeding of coke fines from BF8 fines storage bins to existing
conveyor C102.
v. New Fuel & Flux Crushing and Screening system
vi. New Conveyor route starting from C104 through Rod Mill feeding
to existing Proportioning building.
vii. New Conveyor route starting from L105 through Hammer Crusher
feeding to existing Proportioning building.
The above will be achieved by providing new hot redundant PLC
with suitable remote I/O station. New PLC will be integrated to the
existing PLC based Automation system by providing suitable
gateway as shown in the enclosed Automation Configuration
Diagram. For interfacing with New Sinter machine suitable gateway
also will be provided for establishing interlocking, signal, monitoring
etc.
The Automation system facilities will be generally offered inline with
the basic ‘Automation System Configuration’ diagram (Drg. No:
MEC/S/9101/11/E9/55/01/064.04/R3) enclosed with this specification for
Augmentation in Flux - Fuel Preparation and Plant Return Fines
Handling for SP III.
Contractor will provide gateways, all hardware and software required for
integrated operation of the new drives defined above along with the
existing equipments for flux and fuel crushing & screening facility and
the associated conveyors in existing Rockwell make 5-60/5-80 series
PLC based Automation system.
