Pursuing Excellence

PURSUING EXCELLENCE IN QUALITY - GREEN STEEL

India has announced its commitment to reach net zero greenhouse gas emission by 2070. This lays down a long term road map for companies in India’s industrial sector especially Steel industries. SLRM has already started strong & focused action in this direction to reduce Carbon Footprint (CO2 reduction). We are able to control CO2 emission to 2.1 against 2.5 TCO2 eq/TCS in other steel plants of similar capacity.

1. Energy saving (Electricity and Gas):

Company is constantly working on energy saving and has obtained remarkable improvement as below -

At SLRM Blast Furnace Flue gas is used as a basic fuel for Sinter, Stoves of Blast Furnace, Captive Power Plant & Reheating Furnace at Rolling mill instead of fossil fuels like Oil & Coal.
Captive Power Plant: The captive Power Plant installed in house, utilizes Blast Furnace gas as basic fuel which is clean fuel technology. In a smart step for environmental protection, the technology applied is tailor-made to recover enthalpy of Blast Furnace gas specifically designed to facilitate power generation of 6MW(CPP1) and 7MW(CCP2).
Specific energy consumption of each division in the plant is monitored. By adequate measures & controls, SLRM has achieved the energy saving in power consumption

2. Actions on using Green Energy:

We at SLRM are committed to and working towards safe and Green Steel with constant focus. Successful efforts are made to increase green energy consumption in steel manufacturing by adopting sophisticated processes & practices of power generation through Wind power, Solar power & Hydro power %Green Power used for steel production.

3. Continuous reduction in CO2 footprint:

We are continuously increasing the green belt area in the manufacturing facilities. We have planted over 96900 trees and will plant additional 25,000 saplings during 2025.

PURSUING EXCELLENCE IN QUALITY - CLEAN STEEL

The Clean Steel is the steel in which the content of impurity elements, such as phosphorus, sulphur, total oxygen, nitrogen, hydrogen (including carbon sometimes) and inclusions are very low. The impurity elements vary with different grades of steel. Some element is harmful to certain steel grade, but can be less harmful or even useful in another steel grade. In other words, the control of elements are different for different performance demands of steel. The term 'Clean Steel' is normally used to describe steel which has

1. Control of Tramp Elements like Cu, Sb , Sn, Ti, B , Pb, As etc

2. Control of inclusions like Sulphide, Aluminate, Silicate & Oxide

3. Low gas level (O2, N2, H2)

4. Low Phosphorous content

At SLRM we are evaluating the steel cleanliness by Immersion UT, EVA along with K series & ASTM series of inclusion rating. Special features of SLRM to produce Clean Steel-

Able to control unwanted Tramp Elements to a very lower level as steel production is through virgin route & no purchased scrap is used. Only own house generated scrap is used.

Able to control Phosphorous in steel as the steel making is through specially designed EOF (Energy Optimization Furnace).

Able to produce steel containing very low level of inclusions and gas content through VD (Use of mechanical pump to 0.4 mbar within 5 mins).

Closed controlled casting of blooms is done through effective Argon Shrouding, Slag Detector, EMS (Electro Magnetic Stirrer), AMLC (Auto Mould Level Control) resulting into cleaner steel with improved overall steel quality & fatigue properties. 5. Rolling with High Reduction Ratio.
