The plant is based on Danieli Olivotto Ferrè technology for recrystallization annealing of coiled strip in 100% hydrogen atmosphere. Turkish steelmaker Atakaş released the final acceptance for six bell annealing furnaces in operation at Iskenderun. The supply consisted of the addition of six new bases (three furnace bells and three cooling bells) to the existing BAF eight-base line installed and started-up by Danieli in 2018, along with the complete cold-strip complex. The upgraded facility now is capable of processing prime-quality annealed sheet products of cold-rolled carbon steel for the general and automotive markets – CQ, DQ, DDQ and EDDQ quality, according to the related international standards. Maximum diameter of coils is 2,000 mm, with strip thickness ranging from 0.3 up to 2.0 mm. Up to five coils (100 tons) are charged on the treatment base, which is enclosed by a stainless steel inner cover that maintains a perfectly sealed working atmosphere. The working atmosphere is purged with nitrogen, then filled with hydrogen, which is used to speed up heating and cooling times, to protect coil surface from oxidizing and to ensure brightness. A heating bell is positioned on the base to start the heating and soaking phase of the cycle, reaching the metallurgical transformation temperature (up to 750 °C) with +/- 10°C uniformity. The heating bell is removed with the crane and a dedicated cooling bell is then placed over the inner cover to reduce the cooling time to the minimum, maximizing the production rate. At the end of cycle (typically 35/40 hours in total) the treated coil features perfect mechanical/metallurgical properties, homogeneous between surface and coil center. All process parameters, as well as safety functions, are managed by Danieli Automation control system. Contractual performances including consumption and emissions were achieved. Erection and commissioning phases have been optimized so that the plant stoppage for the integration of the new bases was reduced to two weeks.

A silent but solid relationship which reflects the characters of the two regions and appears destined to become stronger in these challenging times. This is a relationship between the Friulan plant maker Danieli and the region of Liguria. It was back in 2000 when the corporation from the province of Udine decided to move its operational furnace segment to Liguria, in one of Europe’s steelmaking capitals, while keeping its offices in Milan and opening other offices in Pune, India and in Turin through the acquisition of Olivotto Ferrè. “Today from Genoa our engineers export Italian technology all over the world. We have a product portfolio full of offers that range from furnaces for rolling mills to heat treatment furnaces to process both steel and aluminum”, explains Fabrizio Pere. Almost all employees and operational headquarters of Danieli Centro Combustion are located in Genoa rom where Mr. Pere coordinates the work of 200 people (125 in Italy, 75 in India) who operate on international markets for reheating and heat treatment furnaces for the steel and ferrous materials industry. “This is thanks to a very strong relationship with the territory – says Pere – In Genoa, with the support of an important research and experimentation center set up on the University Campus of Savona, we design and manufacture cutting-edge plants for the thermal industry. In Savona, again with the help of the Faculty of Engineering, we are studying how to improve combustion efficiency and reduce the environmental impact of the plants that we will be offering our customers all over the world”. We are seeking an increasingly effective collaboration with the University of Genoa, not only in the field of research and development but also in terms of finding excellent resources for training courses, curricular and post-curricular internships together with our Academy, starting with the last-year students of specialized technical institutes”. “We want to take advantage of our international experience by sustaining the local economic and productive system. First and foremost to provide the company with a guarantee of continuous development in the territory ”. In Genoa, the Friulan group is also present in the area of Genova Campi, employing 70 people at Danieli Automation and Danieli Telerobot.
At the Danieli Centro Combustion’s laboratory of Legino dedicated to the study of steel processing they believe in the importance of continued testing. And they have also believed in the university campus to the point of basing their research and development center in the university of Savona, where they study how to improve products while reducing the environmental impact. These are the engineers of Danieli Centro Combustion, one of the leading companies in the field of reheating furnaces and heat treatments for steel and non-ferrous metals. The models designed in the Genoa office and tested in Savona university campus are prototypes of the innovations to be launched onto the market of North and South America, East Europe, Russia, as well as China, Thailand and Malaysia. This creates an indirect link between Savona and the rest of the world, passing through India and the Danieli Mumbai facility. “The relationship with research and university is essential – says Enrico Mozzi, CTO (chief technical officer), member of the Board of Directors and Head of the Danieli Research Department – We have always maintained a privileged relationship with the University of Genoa, because of the specific competence it has in this field. Since 2012, with the opening of the Savona Campus research center, this collaboration has become increasingly intense. In a time span of seven years, we have invested in this center which has developed from one single research furnace into a plant equipped with four furnaces controlled by one centralized system which collects and manages all the data.” Three engineers work in the laboratory, often co-operating with university teachers or students involved in internship programs. It is therefore an important opportunity for the Campus students who, in the Savona center, can gain work experience with a leading company in what could eventually become their future job after graduation. “In the Savona center – says Mozzi – we study how to improve burners and how to reduce their polluting emissions, also in relation to the increasingly stringent requirements imposed by the relevant legislation”. This center offers plenty of opportunities for carrying out projects and research jointly with the university “close to home.” Danieli Centro Combustion is a company with a well-rooted history. It was established near Milan in the early 1990s. In 2000, during a strong renewal period, it moved its operational center to Genoa, a city with a very long steel-making tradition. DCC has grown constantly, passing from 25 to around 100-million-euro turnover. It counts approximately 200 employees in its various offices of Cinisello Balsamo, Genoa, Turin and Pune (India), who work in close cooperation with the rest of the Danieli Group. In this period, in the laboratory of Savona we are working on the study of a naked flame burner for a horizontal furnace intended for a steel strip galvanizing line to be installed in Russia. We have also other experimental models ready for testing in the Campus laboratory.” Because research plays an essential role – concludes Mozzi – not only to stay ahead, but also to allow the company to measure itself against its international competitors.
This is the third reheating furnace supplied to JSW Steel, which, once again, confirms its trust in Danieli. JSW Steel has ordered a new 220 tph walking beam furnace for its Wire Rod Mill #2 in Vijayanagar-Tornagallu, Karnataka state, India. The new reheating furnace will process mostly special steels like low-alloy, high-carbon, free-cutting steel, etc. which will be transformed into 1.2 Mtpy of wire and rods ranging from 5.5 to 25 mm and coils up to 2.5 t. The scope of supply includes design, mechanical and electrical equipment, advisory services for erection and commissioning. Optimum (reheating process) combustion management will be achieved through MAB -Multi Air Staging Burner flameless technology managed in the PHL-Proportional High Low mode. The furnace will be equipped with L1 and L2 automation system, and will be operated, based on Danieli Automation and Danieli Centro Combustion furnace thermal process and billet handling, in complete auto mode, with integration of upstream and downstream facilities. The first hot billet is planned by third quarter of 2019. As JSW's technology partner in reheating furnaces, Danieli was entrusted for third reheating furnace in a row.
Pao Severstal has selected Danieli Centro Combustion for the supply of a new coal test oven to be installed in the coke sinter BF shop. The aim of the new facility is to carry out semi-industrial tests with different coal burdens in order to determine the optimum parameters for coking processes and to evaluate new coal blends for OpEx optimization. Danieli Centro Combustion will engineer the 400-t test oven, gas treatment section and post-combustion system, supplying all mechanical, electrical, automation equipment and laboratory ancillaries. Technical assistance during erection and commissioning will complete the scope of work. Among the main technical characteristics to be noted are the stamp charging process and coke dry quenching system. Coke oven gas is carefully treated through a scrubber, cyclone, and tar separator, and safely burnt by a post-combustion system. This way, the emissions are drastically reduced within the most stringent standards.
A hotbed of experiments and research: This is the ideal word to define Danieli Centro Combustion’s R&D center for combustion systems, located on the Campus in the city of Savona. This is where, once again, research, experimentation and business come together. “Here, surrounded by young people, there is ample room for growth”. A hotbed of experiments and research: This is the ideal word to define Danieli Centro Combustion’s R&D center for combustion systems, located on the Campus in the city of Savona. This is where, once again, research, experimentation and business come together. A hotbed - and this should rightly be noted - of ideas and prototypes. But also a model shop, where once the models have been checked and prepared, they are launched into production and then onto the market, as part of one of the most well-known industrial brands in Italy that is exported all over the world (exports account for more than 90%): Daniel, which specifically selected Savona and its university for the purpose of experimentation. “Why the Savona Campus? Because it is the ideal location to conduct research – explains the Vice-President of Danieli Combustion - Matteo Giacomo Ricci – “We have been here since 2012 and have found the perfect area in which to combine experimentation, technology and sufficient space. In addition to the enthusiasm of the young students and engineers that are connected with the Campus.” This is the turning point that creates a link between the workplace with the university, providing significant opportunities for youths. “We are constantly searching for new talent” says Ricci. We seek young university students who are about to graduate, and ready for an apprenticeship and a training experience with us. These are very important opportunities for the future which, in some cases, while the students are actually preparing their degree theses, can become starting points for research doctorates, and perhaps in the future, can turn into actual jobs. The University of Genoa and the Campus “turn out” highly knowledgeable engineers. I have ascertained that more than 50% of them are better than average. But some shortcomings were noticed with regard to practical skills: concrete experience. And this is why for years now I have been urging the Campus youths to: seize any opportunity to experience the reality of industry and of the workplace. Danieli’s doors are open.” It is no coincidence that the two employees of the experimentation center in the hangar of Legino are former Campus students. Matteo Mazza, head of the laboratory, and Giovanni Carozzo, specialist in thermo-fluid dynamic simulations. “Danieli – says Ricci- manufactures furnaces for heavy industry. High temperatures to melt metals from steel to aluminum. Here we have four furnaces where we are experimenting on new burners with new features: greater resistance, less pollution, and less consumption. Simulations, tests, prototypes and then, once a significant result has been reached, we begin to produce them”. The product, which is supplied to every corner of the world, is created right here in Savona. An opportunity the students should take advantage of.
