Hadeed Saudi Iron & Steel Company gives approval to Tenova’s i DRI® technology project
August 3, 2017
Hadeed Saudi Iron & Steel Company has signed a final acceptance certificate for the Tenova i DRI® project for the successful delivery of the Furnace Optimization System on DRI fed Electrical Arc Furnace (EAF) 5 at Hadeed Plant. The i DRI® technology project at Hadeed has demonstrated performance in the areas of 1.42 per cent yield increase, 4.1 per cent productivity increase, 3.23 per cent reduction on electrical consumption and 1.6 min reduction on Power on Time (PON).
As applied to the DRI process, the models are responsible to calculate the most important parameters used by the control modules. Working alongside the plant PLC, performance of the system was achieved through validation of several fundamental outputs, inclusive of off-gas measurements using EFSOP® technology, a downstream analyzer, temperature and off-gas flow sensors, DRI feed rate control, etc.
