Trinecky in乞enyring, a.S. has given prime怡IS Techn010gies the final acceP怡nce certificate forthe
modernized secondary dedusting system inste11ed in the Trinecke 之elezarny a.S. converter steel works.
Trinecky in乞enyring, a.S. was selected by Trinecke 之eleZ■rny a.S., as a turn key supplier. The project
Was financed from czech and Eu funds. The system rernoves the dustfrom two converterlines and
Secondary plant equipment.吐 is designed to purify 2.4 mi11ion cubic meters of gas per hour. The dust
Content ofthe puri"ed 0仟・gas has been reduced to less than one mi11四ram per S怡ndard cubic meter. For
the 打rsttime, the dust 介om the desulfurization stations is trapped and c011ected separately. The use of
modern system control and bloW引 drive techn010gy optimizes energy consumption. The hot metal
Charging has also been speeded up to increase the production cepacity. primetals Techn010gies
received the ord引from T而necky in之enyring in December 2012. The 行rst upgraded converter ceme into
OP引ation in october 2014, and the entire plant has been fU11y oP引ational since the stad of octob引 2015.
Trinecke 之elezamy is one ofthe longest・standing industrial companies producing iron and steelin the
Czech Republic.1ts r3nge of products includes rails, wire rod, bars, semi"nished products, seamless
tubes, and drawn steel.1n 2014,the compeny produced some 25 m川ion metric tons of steel, which
made 壮 the largest steel producerin the czech Republic. The liquid steelis produced in two LD 旧OF)
Converters, each with 3 恰Pping weight of 180 met而C tons. As the steelworks is located neerthe inner

dty, Trinecke 之eleZ合my places high priority on not only keeping below the dust content emission limits,
but also on noise protection. The sound pressure level ofthe new plant has accordingly been reduced to
Iess than 80 dB(A).
P"metals Techn010gies was responsible for basic and detail engine引ing ofthe process eqUゆment, for
Supply of main components, and they rendered advisory services during equipmentinsta11etion. Trinecky
in乏e"yring, a.S. was responsible for civil engine引ing and local manufacturing of process equipment
based on the det3il engineering of primetels Techn010gies. Moreoverit was responsible also for a11 Civil
Works, ad3Ptation ofthe BOF building and a11 erection works ofthe process equipment. The 0什・gases
from the two converters are pu「愉ed dunng charging and tapping. The 0什四ases from the discharge pits,
the desulfurization stations,小e secondary meta11Urgy station,the lance treatment and the wire feeding
Stations are also pur所ed. A roof、mounted extractor was also insta11ed.
Two blowers, mounted on special sprung foundations and each with a power of 3,6 megawaせS, extract
the requisite volume of 2.4 mⅢion cubic meters of gas per hour. static coolers reduce the temperature of
the 0仟・gases during chergin9 to less than 180 ゜C.1n comparison to the old dedusting system,insta11ing
Static coolers in the charging !ine has speeded up recharging with hot metal, and so increased the
Production capecity. The dusts are deposited in 20 filter chambers. Forthe firsttime in a system ofthis
type, four ofthese chambers are used to purify the 0仟・gases from the desulfurization stations. The dusts
from these geses are c011ected in separate containers.
0小引 Specialfeetures ofthe new dedusting system include using computation引 Fluid Dynamics (CFD)
model calculations to optimize the charging hood, while atthe seme time capturing the smoke, and
det引mining the most e什icjent 例ter size. A combination of sophisucated plant control and modem drive
techn010gy forthe blowers ensure low ene四y consumption forthe oV引a11 Plant. P3tented 例ter cleaning
moduleS Ⅷth d治Phragm valve techn010gy minimize compressed air consumption. The new system also
Sets stendards on the structural side. As space is limited,it h3S been insta11ed on a nine・meter-high
Pla廿orm above a r03d and severalrailtracks.
