IISCO steel plant begins trial run

IISCO Steel Plant of SAIL at Burnpur has recently begun trial productions in some of its new units -- coke oven battery No.11, sinter plant and sinter disposal facility. Delayed by around two years, packages of 2.5 million tonnes per annum project are coming on streams in stages.

“The new battery is now primed to contribute significantly in improving overall bottom line of the company,” according to Narendra Kothari, Chief Executive Officer of ISP.

A consortium led by Giprokoks of Ukraine installed the 0.882 million tonnes 7-metre-tall battery with 74 ovens and a cooling plant. McNally Bharat Engineering Co along with DMT of Germany erected a matching by-product plant.

The coke cry cooling plant (CDCP), first in SAIL, eliminates quenching emission with heat recovery to generate power. Instead of conventional water quenching, the facility cools the red hot coke by inert gases.

Earlier, this month ISP had conducted a hot trial of the new sinter unit. The first lot of about 600 tonnes of sinters was sent off to Bokaro Steel Plant. The sinter disposal system, which also became functional, consists of storage silo of 700 cubic meters whose outlet is provided with belt feeder of variable capacity of 600-1200 TPH to feed rake of wagons.

While some of the main packages at Burnpur are almost ready for commissioning, remaining are in an advanced stage of completion close to commissioning stage. The major facilities that would make the ISP a new integrated steel making outfit will include a coke oven battery, two 204 sq. m. sinter machines, a blast furnace with coal dust injection system, three 150-tonne BOF converters, two 6-strand billet casters and one 4-strand bloom-cum-beam blank caster, a 0.6 mtpa heavy section mill, a 0.5 mtpa wire rod mill and a 0.75 mtpa bar mill.
