1. To Produce 75mm billet from 250x250 mm, as per
manufacturer we need to operate
RMT(8),IMT(4),FMT(2).
2. To ensure trouble free operation closed CVS is
envisaged for cooling of main drives in all three
train resulting in energy consumption for cooling.
3. There is need for relocation of strands with a view
to operate at full capacity in each mill train and
minimize wastage of energy.
4. This resulting in energy loss of 480KW for running
of CVS fans.

1. Based on the study and finding out various
alternatives, the team decided to shift 2 nos of FMT
strands to IMT with suitable selection of roll, beam
and guides along with casette selection.
2. A trail run was conducted after relocation and it
was running successfully and rolling rate remains
same.
3. CVS fan in FMT are stopped.

Best Practices implemented in Green Supply chain
• Implementation of Green Technologies
• Implementation of ISO :50001 Energy Management System(
SAIL/DSP implemented . SAIL BSP is replicating EnMS based on
RINL experience).
• Increasing Transportation of Steel Products and By products
through Rail (% loading by rail increased from 41% in 2016-17 to
57% in 2017-18).
• Receiving Raw Material (Coking coal) from Ganagavaram Port
instead of Vizag Port.
• Procuring Energy Efficient Equipment(Life Cycle Criteria for
Procuring Energy Efficient equipment)
• Production of Green Steel( Steel Consumption reduces by 15% due
to high yield strength of 550 N/m2 on Fe 550 grade)
35
Green Purchasing Policy
31
• Procurement of Circulation fan(3000KW) for
Sinter Heat Recovery Plant
• Star labeled Energy Efficient Air Conditioners
• Energy Efficient Motors
Year ENCON Investment as % of
Turnover
2018-19 0.8%
Involvement of employees, Team Work and
Monitoring
• Employee Involvement Through
– Quality Circles, Suggestion Schemes, Department Energy
Teams, Participation in Energy Conservation Campaigns, Cost
Control Campaigns, Water Saving Campaigns
• Implementation Methods
– Low Cost/No Cost Ideas (Process Improvements, House
Keeping Measures, etc) will be Implemented by Frontline
officers
– Medium Investment Projects through AMR Schemes
– High Investment Schemes through Board Approval/COM
– Special Task Forces for Implementing Important Energy
Conservation Projects for Sinter Cooler, Steam Utilization and
By product gases usage.
