India’s Ministry of Steel has sanctioned INR 15 crore funds each in 2018-19 & 2019-20 for Promotion of Research & Development in Iron & Steel Sector. The energy efficient and environment friendly technologies adopted by steel industry as part of technological up gradation, modernisation, expansion programme & projects include the followingCoke Dry Quenching - Power generation from the waste heat from CDQSinter Plant Heat Recovery - Power generation from Sinter Cooler Waste HeatBell Less Top Equipment in Blast FurnaceTop Pressure Recovery Turbine in Blast FurnacePulverized Coal Injection system in Blast FurnaceHot stove waste heat recovery in Blast FurnaceDry type Gas Cleaning Plant in Blast FurnaceCast House & Stock House Dedusting systemConverter Gas Recovery in BOFEnergy Monitoring & Management SystemsSecondary Fume Extraction System in Steel Melting ShopRegenerative Burners in Re-heating Furnaces of Rolling MillsHot charging process of continuously cast products at higher temperature directly to Rolling MillsDirect Rolling Process eliminating the need for Re-heating furnaces.Energy efficient technology for Hot Strip Mill - Flexible Thin Slab casting & RollingNear Net Shape casting: Bloom cum Beam Blank caster, Bloom cum Round caster etcAdoption of Variable Voltage Variable Frequency Drives for high capacity electric motorsThe wastes generated are recycled back within the steel plants. Solid wastes such as Blast Furnace slag is granulated within the steel plant and sold to cement industry. Gaseous wastes generated from the processes are further used in downstream processes in the plant such as in the reheating furnaces and power generation. Further, Research & Development projects have also been undertaken for utilization of steel slag in road making, construction, agriculture etc.
