Danieli Corus has signed a contract with Severstal for the reline of Blast Furnace No. 5 at their Cherepovets plant in Russia. gas variables pogil worksheet answer key As part of this project, the blast furnace shell, refractories and cooling system will be replaced and the scope of work for the majority of these items is based on design, supply and construction and commissioning supervision.

Following the outstanding achievements with Blast Furnace No. 4, which was converted by Danieli Corus to a “Hoogovens” type cooling and lining system in 2005, Severstal has decided to apply this technology to their flagship Blast Furnace as well. This cooling and lining design is based on machined copper plate coolers in combination with high conductivity graphite, which is the only design with proven capability of achieving campaign lengths in excess of 20 years regardless of ironmaking process circumstances.

After completion of the project, Severstal Cherepovets No. 5 will be the largest Blast Furnace in the world. The furnace has 40 tuyeres and 4 tapholes and is designed for an annual production of more than 4.7 million tons of hot metal. The reline is scheduled to commence in early 2020, with deliveries of materials to site taking place in 2019.

Ukrainian steelmaker Zaporizhstal has signed a contract for a new top charging unit for their Blast Furnace No. 3 with Danieli Corus. The furnace will be rebuilt in early 2017 and Zaporizhstal requires increased production and availability levels for the next campaign. The contract for the Danieli Corus Top Charging Unit with DANCU Gearbox, which is a co–development with Danieli Centro Metallics, was awarded after a thorough comparison of all available top charging technologies.

Chute–type charging devices have proven to offer optimum control over the distribution of raw material on the blast furnace stockline. However, traditional electro–mechanical technologies are known to have vulnerabilities and since the charging unit largely determines the availability of the blast furnace and requires long outages in case of exchange, Danieli Corus and Danieli Centro Metallics have developed this new technology with the main objectives of maximum availability and maintainability.

To achieve maximum reliability as well as the most consistent positioning of the chute, hydraulics were selected for most of the core components of the unit. All main components are designed and manufactured to be failure–free or redundant for uninterrupted operations. The rotating and tilting movements of the chute are achieved with only four moving parts, making this charging unit the most robust design available.

A common operational practice in the Russian and Ukrainian steel industries is the application of hot raw materials such as sinter as stockfeed for the blast furnace. To accommodate this practice in this cold environment, all major equipment is engineered and manufactured for the ability to accept raw materials with temperatures up to 700 degrees as well as e.g. frozen coke. Valves need to enable pressurization in cycles and charge precisely the required amount to the distributer. Main valves are steam–cooled to ensure long lifetime.

Recently, the PCI system at ArcelorMittal Kryvyi Rih No. 9 was completed and commissioned successfully. The scope of the project included the coal grinding and preparation plant as well as the dense phase coal transport and injection system for this 42 tuyere furnace. gas in dogs causes The system includes a traditional PCI building for the grinding, preparation and storage of the pulverized coal. To maximize health and safety, the distributor is positioned at an elevation around the furnace’s tuyere level and located, along with a large portion of the injection lines, in a separate distributor building. Injection is based on the principle of equal pressure drop over the injection lines, which has the advantage of achieving equal coal/gas ratios at all tuyeres based on simple physical principles and without installing superfluous measurement and control equipment.

This blast furnace has an inner volume of 5000 m³, making it the country’s largest. The furnace produces 9500 tonnes of hot metal per day. The PCI system was designed for peak injection rates of up to 200 kilograms of coal per tonne hot metal. electricity and magnetism review sheet During the commissioning and ramp-up phases, sustained injection levels of 150 kg/tHM were achieved. This eliminates the requirement for up to 150 kg/tHM of expensive metallurgical coke charged via the top of the furnace, bringing ArcelorMittal Kryvyi Rih substantial savings in their ironmaking operations.

Danieli Corus has completed the repair and rebuild of Hot Blast Stoves at the JSW Steel Bellary Plant in Toranagallu, India. Given the precarious state of the existing Hot Blast Stoves of a competing European design at Blast Furnace Nos. 3 and 4, Danieli Corus was asked in 2014 to carry out emergency repairs on four of the stoves (two from each Blast Furnace) so that the Furnaces would be able to continue operation in the short term. In the second stage of the project, Danieli Corus has rebuilt two stoves (one from each Blast Furnace) where a substantial portion of the internals of the stoves were replaced. These were commissioned recently.

Blast Furnace Nos. 3 and 4 are the largest at the Toranagallu plant at a working volume of 3445 m³ each. They were started up in 2009 and 2011 respectively, but within one year after start-up, JSW observed hot spots in a number of areas of the hot blast system of both furnaces. Espcially in the stoves of Blast Furnace No. 3, additional problems such as leakage and damage were found. These problems forced JSW Steel to modify the operating parameters for the furnaces, compromising the operational targets.

Danieli Corus has successfully commissioned the final two of seven Sublance Systems at JSW Steel in Toranagallu, Karnataka, India. electricity in india travel Sublance Systems No. 2 and No. 3 at SMS-II were successfully installed and cold commissioned. On February 6, the first ‘hot dip’ with Sublance No. 3 was performed. Finally, on February 12, the first ‘hot dip’ with Sublance No. 2 took place.

The hot commissioning of these two final systems at SMS-II results in a total of seven working Sublance Systems at JSW Steel: three at SMS-I and four at SMS-II. The first Sublance at SMS-I was commissioned in February 2013 and one year later, JSW Steel has become the first Indian steel plant to be fully equipped with Sublance-Based Process Control Systems.

All systems the newly developed DIRC-6 and are based on the Level 2 Static and Dynamic Model for BOF Process Control. h gas l gas brennwert This makes the JSW Steel plant in Toranagallu a perfect showcase for the Indian steel industry. This market has long been reluctant with respect to implementing Sublance Systems, but with these seven Danieli Corus systems up and running, JSW Steel has proven the value of Sublance-based BOF Process Control in terms of efficiency and steel quality.

Danieli Corus has commissioned the greenfield Blast Furnace No. 5 built for SAIL (Steel Authority of India Limited) at their Rourkela (Odisha, India) steel plant. This blast furnace was built by a consortium consisting of Danieli Corus and Tata Projects Limited and is currently India’s largest Blast Furnace. The first hot metal was tapped after 27 hours.

It is a major milestone for Danieli Corus for having built the largest operating Blast Furnace, according to the “Hoogovens” philosophy, in this important market. The Furnace is named after the Hindu goddess Durga and was designed to European standards and based on European technology. It was built to produce around 8,000 tonnes of hot metal per day for a twenty year campaign and is part of a 1.75 Million Euro expansion program at the Rourkela Steel Plant. A “pooja” was performed as part of the commissioning of Blast Furnace No. 5 (“Durga”) — according to Hindu tradition, coconuts were cracked and the contents sprinkled over the Furnace’s shell to honour the Goddess Durga.

This is the fourth greenfield Blast Furnace project completed by Danieli Corus in India and based on the “Hoogovens” philosophy. Previously, three smaller Blast Furnaces were built for private companies, of which the one operated by Jindal Steel & Power Ltd. has been the country’s best performing Blast Furnace over the past years. In addition, Danieli Corus has executed substantial revamp and repair projects on the Blast Furnaces operated by Tata Steel at their Jamshedpur plant. An order for a fifth greenfield project in India was received from the mining company NMDC in 2011. This company is diversifying into the steel industry and is developing a new integrated plant at Nagarnar. electricity laws in india Danieli Corus is currently building the Blast Furnace, which will be larger than the “Durga” Furnace operating at Rourkela.

Danieli Corus has received the order for the rebuild of Blast Furnace No. 1 operated by Alchevsky Metallurgichesky Kombinat (AMK), Alchevsk, Ukraine. The furnace will be rebuilt based on the integrated high-conductivity blast furnace cooling and lining system with a dense copper plate cooler pattern. This is the only design with a proven capability for long campaigns despite the substantial thermal, chemical and mechanical attack that come with operating at e.g. high productivity or on sub-optimal raw materials quality.

Компания Danieli Corus получила заказ на в рамках проекта по ремонту доменной печи №1 Алчевского металлургического комбината (АМК), г. Алчевск, Украина. Реконструкция печи будет проводиться с применением комбинированной системы охлаждения и футеровки доменной печи с плотным расположением горизонтальных медных холодильников, обеспечивающих высокий теплосъем. Такая конструкция является единственной системой, гарантирующей бесперебойную работу в течение длительных кампаний, несмотря на значительные и неравномерные термические, химические и механические воздействия, возникающие при работе домен с высокой производительностью, значительными показателями вдувания ПУТ, а также с нестабильным и не наилучшим качеством сырьевых материалов.

The first Danieli Corus Sublance, which is one of the key components of the Automatic Steelmaking System, was put into operation in the Summer of 1980. gas utility boston Recently, Danieli Corus was awarded the order for two BOF Process Control Systems including two sublances, two waste gas analyzers and two automatic slag control systems for the new converters at Zhangjiagang Rongsheng Plate Co. Ltd. in China. This brings the total number of references for the Danieli Corus Sublance to 100.

This achievements confirms Danieli Corus leadership in Process Control Technology for BOF Steelmaking. The system has unrivaled hit rates and availability times and the value of the system is reinforced by the extensive process know–how it is based on. This know–how was accumulated during the commissioning and further fine tuning of systems on all continents, working under all kinds of process circumstances.

Ever since its inception, when it brought the operator on–line insight into essential process parameters, the system has been improved to become what it is today. The integrated control system that it has become part of is capable of producing steel with all plant control systems running in full computer mode and recent additions to the capabilities of the sublance itself have been slag sampling and on–line phosphorous measurement of the liquid steel bath.
