Nikko successfully concluded the hot run test at TY Steel Thailand. The Customer was really satisfied about operation and time schedule.

The furnace is equipped with Brar’s secondary circuit, water cooled cables and Aluminium conducting arms.

Introduction

M/S BPSL has started replacing cables from 2009- 2010 and recently noticed unpredicted failures in Cables causing stoppage of Furnace.

M/S BPSL contacted M/S Brar India Pvt. Limited to submit the detail report of all cables in operation. M/S Brar India Pvt. Limited deputed team with Telemaster System and successfully made measurement of all cables on installed positions.

At present 4 nos. of EAF and 4 nos. LF are in operation at M/S

Bhushan Power and Steel Limited. EAF 1 , EAF 2 and LF1, LF2 were commissioned in 2007 and remaining in 2010. Two EAF

commissioned in 2007 are powered with 60 MVA Furnace

Transfomer and remaining two with higher capacity Trafo of 84 MVA.

Measures

Brar India team with Telemaster System and successfully made measurement of all cables on installed positions.

Taking into consideration that in this case the nominal resistance value of a new water cooled cable is 57μὨ (Cable 3000 Sq.mm, 9800mm long) and it is usually suggested to change the cable when the resistance value becomes more than 85μὨ (150% of the nominal value), from the measurement values in EAF 1, 2,3, 4 that cables marked RED were to be replaced immediately.

Final Consideration / Recommendation

Thanks to these measures BSPL could arrange a preventive maintenance plan to change the cables with high resistance and avoid unpredicted failures in Cables causing stoppage of Furnace.

Furthermore BSPL confirmed they now keep records for each water cooled cable, schedule water cooled cables replacements well in advance avoiding furnace stop, increase productivity, prevent overload pf other cables in parallel and save power losses.

TELEMASTER is the new innovative system developed by BRAR to monitor the water cooled cables electrical electric performances, predict the failure in advance and reduce power losses.

Today more than 500 water cooled cables of 45 furnaces has been monitored by the TELEMASTER.

ТОКОПРОВОДЯЩИЕ АЛЮМИНИЕВЫЕ ЭЛЕКТРОДОДЕРЖАТЕЛИ 

Мы разрабатываем и изготавливаем классические и инновационные токопроводящие электрододержатели из меди/стали или алюминия.

Нашим подходом всегда было предоставление систем “под ключ”, заботясь обо всём, начиная со стадии проектирования и заканчивая производством и инсталляцией, включая  помощь на месте установки.

Материалы и структура

Алюминиевые токопроводящие электрододержатели являются альтернативой биметаллическим медно-стальным и используются в установках, в которых требуется свести к минимуму вес оборудования.

BRAR может предложить два решения:

> "Коробчатый тип”:  - Корпус электрододержателя, при этом,  схож c корпусом биметаллических электрододержателей "коробчатого типа". Охлаждающая вода в данном случае полностью заполняет корпус. Внутри такого “рукава” также имеются усиливающие элементы для компенсации давления воды и повышения механической прочности. Специальный дизайн внутреннего пространства также гарантирует быстрое движение воды вблизи внешних стенок, где происходит нагрев.

> “Профильный тип”:  - у BRAR имеется большой опыт в изготовлении алюминиевых профильных охлаждаемых электрододержателей, в которых охлаждающая вода протекает внутри перегородки, а не внутри держателя. Сечение профиля представляет собой формы "L" или "C" с охлаждающими отверстиями, изготавливаются из тянутого алюминия. В этом случае электрододержатель охлаждается только там, где необходимо, т.е. в профиле, через который протекает электрический ток, значительно снижая, таким образом, потребление охлаждающей воды.

Преимущества

♦ меньший вес

♦ экономия электроэнергии

♦ простое обслуживание

♦ низкий уровень вибрации

♦ быстрое реагирование на регулировку электрода

По сравнению с биметаллическими, алюминиевые электрододержатели намного легче: "коробчатый тип"  - на 30%,  в то время, как "профильный тип" - на 40-45% легче. 

Значение реактанса сравнимо с биметаллическими держателями, а экономия электроэнергии может достигать 5%!

Для обеспечения хороших показателей алюминиевым электрододержателям требуется охлаждающая вода высокого качества (деионизированная вода с низкой проводимостью).

Thanks to a long-term cooperation in design and manufacturing of high-current products and services, on November 2015 INTECO Melting and casting Technologies Gmbh Austria awarded to BRAR the qualification as supplier of CLASS A (min 83%).

BRAR achieved a total rating of 99% on Quality and Environmental Management, Market and Price, Engineering and Logistics.

INTECO is a supplier and partner to the steel and general melting industry since 1973.

BRAR is a leader in systems for high current for electric furnaces.

BRAR is completing the installation of high current connections to anode and cathode for N°6 graphitizing furnaces (current 110kA-DC) for the customer IMERYS.

The supply includes the design, manufacturing, assembly and expediting of the following:

> Connections with pipes made of heavy gauge aluminum, water-cooled, isolated and resinates to be positioned inside of tunnels under-ground.

The tubes have welded flanges to allow the assembly on site of the "bridge" connecting to the cathode. The connection to anode and cathode is made of flexible laminated aluminum.

 

The main target of the Customer was to make the installation in a very short time, so BRAR has designed and manufactured 25m long lauminum pipes conductors 25m in one piece, ready for assembly with a special handling tool.

 

Watch the video transport, amazing!

This is confirmed by our Customers that choose our new technology, know-how, competence, determination and responsability.

Wiliam Rady, our partner in Brar&W.Rady Brazil, once said “ We do not follow, we lead!” and he was right.

A nice example is related to our Quick coupling device.

Many years ago we introduced this new device as “state of the art” in cables handling.

Our special design (fit and remove cooled cables extremely quickly, reducing maintenance times and the relevant costs, in total safety for the operator) met immediately Customer requirements and nowadays has become a must.

This design is so good that today has become a standard also for some Engineering companies like SMS SIEMAG and our German Competitor (!).

This is Brar, this is our Italian leading technology: “We do not follow, we lead!”
