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

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)

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
