JSPL's Raigarh Steel Plant creates world record of 42 heats
This move was made on Nov 14. Earlier Shagun Steel, China held the record with 40 heats in a single day.
In a tryst to augment cost effectiveness in steel making, JSPL developed a new steel making process - New Oxygen Furnace (NOF), wherein steel is made by charging upto 90% of Liquid Hot Metal and using only chemical energy; without the aid of Electrical Energy. This innovative process ensures higher yield and productivity, low capital investment as compared to Basic Oxygen Furnace (BOF). It also leads to lower slag generation and zero electrode consumption.
As part of the transition process from Electric Arc Furnace to Zero Electric Power Furnace, JSPL installed a new high end ‘Oxygen Lances’ in the Furnace along with a high precision Tilting Mechanism and Launder for continuous pouring of Liquid Metal into the Furnace. Charging of Liquid Hot Metal from Blast Furnace into New Oxygen Furnace (NOF), was initiated for controlled and efficient steel making process.
NOF has the flexibility of converting various charge mix of raw material i.e. from 100% DRI to 90% Hot Metal (Zero Electric Power) into steel efficiently. The Furnace is highly adaptable and can be converted from Zero Power NOF to Normal Electric Arc Furnace (EAF) and vice versa in a short span of less than 24 hours.
