Group of Companies
Today, Sree Rengaraaj Steel is composed of five separate units which work together to offer customers a unique solution, one stop steel shop service that cannot be found elsewhere. With as many as five units working together, Sree Rengaraaj steel can be your single source on large requirements.
Production Capacities of the Units
Sponge Iron Plant
We are having 350TPD Sponge Iron Plant in Sipcot Industrial Growth Centre Perundurai, Erode (DT), Tamil Nadu. We procure Iron Ore from Bellary (DT) Karnataka, Coal from South African and Dolomite form Dindugal (T.N). We supply Our Sponge Iron Products to various Induction Furnace, Foundry Division and also for Blast Furnace.
Sponge Iron Rotary Kiln Process
In this process, a Refractory lined Rotary Kiln is used for reduction of iron ore in solid state. The Kiln is mounted with a slope of 2.5 % downwards from the feed end to discharge end.
Waste Heat Recovery Systems
The option available for the commercial exploitation and reduction of specific fuel consumption and cost of production is the waste Heat recovery and power generating system. Waste Heat carried away by the flue gases is being recovered by the Waste Heat recovery Boilers and gainfully used for Steam and hence power generation. Further analysis and studies in the above work has helped to develop Energy Efficient Direct Reduction Process for the manufacture of Sponge Iron. This system envisages recovery of the sensible heat and utilize partly for Pre-heating the Iron Ore and the balance to generate steam and power. Recovery of Heat to Pre-Heat the Iron ore and generate steam makes the Direct Reduction Process more energy efficient and more commercially viable and attractive proposition.
Waste Heat Recovery Power plant Process
Production of Sponge Iron in DR Kiln generates huge quantities of Flue gas carrying considerable sensible heat. Generally, the Waste Gases are burned in two stages in a Chamber known as After Combustion Chamber (ABC) by injecting excess Air to neutralize the poisonous and harmful un-burnt Carbon Monoxide. The burning of the residual CO releases additional heat energy in to the Waste Gases calling for two stages cooling with high pressure atomized water spray. Further, the Hot Gases have to be cooled from 900 to 200 Deg Centigrade, so that the Electro Static Precipitator withstand the temperature. When we install a Waste Heat Recovery Boiler, two benefits could be achieved. Here, the Cooling is achieved by a high Pressure water Sprays. Sulphur Di-Oxide is a constituent of the Waste Gases and while cooling becomes a highly corrosive Wet SO2 which corrodes the steel Components like Gas Ducts, Fan Casing, and Impellers etc. All these Equipments would call for high Capital and Revenue (Maintenance) cost.
Off Gases from DR kiln after “After Burning Chamber (ABC)
The waste Heat Boiler will be installed behind the ABC of DR kiln in bypass configuration. The flue gases after ABC will be taken to unfired furnace chamber and them flow over banks of super heater, convective evaporator and economizer before being discharged to atmosphere through ESP, ID Fan and chimney of DR Kiln. In case of outage of Waste Heat Boiler, Flue gases will pass through GCT- ESP ID Fan and Chimney. The flue gases will pass over various heat transfer surfaces to ESP and then finally discharges in to chimney by ID Fans. The boiler will have its own ESP, ID fans and Chimney.
Steel Melting Division
Well-equipped and advanced Induction Furnaces formulate quality mild steel billet for limited utilization in its Rolling Mill. Uniformity in the physical dimensions and controlled chemical composition are ideally apposite for its Rolling Mill.
We are having 8MW Captive Power Plant Sipcot Industrial Growth Centre Perundurai, Erode (DT), Tamil Nadu, This is Waste Heat Recovery Boiler.
