Brazil’s Aço Cearense Group’s Siderúrgica Norte Brasil (Sinobras) has officially produced the first steel coil at its rolling mill #2 in Marabá, Pará state, Brazil.

A press release said that Sinobras invested in the new mill from Italy’s Danieli to increase its annual production capacity from 380,000 tons to 850,000 tons per year of wire rod and spooled rebar in coils. The mill features an innovative, full cantilever stand configuration with a total of 26 passes. It has 10 cantilever stands arranged in H/V configuration, followed by a series of Delta-type, fast-finishing blocks, with a 45° design, for the remaining 16 passes of the reduction sequence.

The new mill will produce wire rod from 5.5 to 16 mm, and rebar from 6.3 to 16 mm, at a maximum finishing speed of 110 m/s. The project includes a new substation and 230kV transmission line to meet the new electrical load needs of the steel producer and facilitate the use of energy from the Belo Monte Hydroelectric Plant, of which it is a partner as a self-producer.

Sinobras Industrial Director Milton Lima described the expansion as a transformative moment for the Group. “This achievement represents a significant milestone ... taking us to an even higher level. By doubling the size of Sinobras, we are not only expanding our operations, but we are also transforming our company into a powerhouse, generating new opportunities.

Italy’s Danieli reports that it has received orders for two high-productivity and H3 rolling mills to be installed and put into operation in Russia during 2020.

A press release said that AEMZ (Abinsk Electric Steel Works Ltd.) ordered a new 600,000-tpy H3 wire rod line to be installed at Abinsk, in the Krasnodar region. The new mill will produce wire rod coils, 5.5- to 16-mm, smooth rounds, and 6- to 12-mm, quenched and microalloyed rebar, for construction, welding wire and CHQ grades.

The second order is from NPZ (Novorossiysk Rolling Plant LLC), which ordered a new 500,000-tpy H3 wire rod mill to be installed at Novorossiysk, also in the Krasnodar region. The mill will roll 150 x 150 billets into 5.5- to 16-mm wire rod and deformed wire rod in coils weighing up to 2.1 metric tons.

Depending on customer requirements, Danieli notes that its H3 mills operate at over 100 m/sec. They consist of an ESS (Energy Saving System) cantilever-type and SHS housingless stands and fast-finishing blocks; a water-cooling line suitable for wire-rod quenching and controlled cooling, and a loop-laying head, rotary reforming tube and easy-down system for a perfect coil pattern.

Danieli’s H3 mills are typically supplied along with Danieli Centro Combustion reheating furnaces equipped with the latest-generation, ultra-low NOx emission, flat MAB flameless burners. Danieli Automation provides process control, power and instrumentation—like medium-voltage Q-DRIVE, HiPROFILE LITE and HiSECTION measuring devices—for in-line tracking and product monitoring, and optical system for rolling guides set-up, and for rolls and guides alignment for the finishing block.

Italy’s Danieli Group reports that production has begun for the new high-speed wire rod mill it supplied to Acciaierie di Verona (the Pittini Group) that represents the 500th rolling mill the company has now supplied.

A press release at the Danieli website reports that the first coil was recently produced, some 19 months after the contract signature. “The timely start-up and the following hot-test period of seven weeks, during which 25.000 tons of finished wire rod in quality have been produced, reflects the long-term cooperation between the Pittini Group and Danieli,” it said.

Regarding the rolling mill, it was designed to hold strict end-product size tolerances, employing the most advanced wire-rod technology and in full compliance with Industry 4.0 requirements, the release said. It noted that the plant is capable of annually producing 750,000 metric tons (mt) of plain wire rod from 5.5 to 25 mm and rebar from 6 to 18 mm at rolling speed of 100 m/sec, and further outlined the capabilities as follows.

The mill has a high-speed rougher feeding two independent rolling lines that consist of cantilever roll stands, featuring quick roll changes and temperature control along the mill and downstream. High-speed shears, installed downstream the multi-drive, high-speed, twin-module sizing blocks, perform wire-rod head and tail cropping. The fourth-generation loop layers guarantee extended pipe life, quick rotor changes, and no vibration during rolling, resulting perfect loops from heads to tails.  The variable-pitch cooling conveyor features modular slow-to-ultrafast cooling.

 The Danieli Automation Q3 Intelligence system is used for integrated data collection of the whole plant, analysis, and web reporting with Key Performance Indicators and powerful statistical tools to support decision making. The new plant automation ensures consistent product quality consistency, high utilization factor and yield, and workshop coordination, and establishes a link to “Big Data” and plant digitalization practices.

South Korea’s SMS Group has won a contract from Pohang Iron and Steel Company (POSCO)—the fifth largest steel producer in the world and the largest in South Korea—to modernize its existing wire rod mill at its Pohang works.

A press release said that the project calls for the replacement of some equipment along the mill (existing descaler and additional one on the rolling mill), a new cropping shear, a shiftable water cooling line, pouring reel machines with walking beam conveyor, cooling fans and hoods assuring in-line treatment of coils. The plant now produces 540,000 tons per year of wire rod and bar-in-coils for automotive applications from 14 up to 42 mm, with coils up to two tons.

The project, the release said, will allow POSCO to widen coiled round products up to 55 mm, and smaller products rolled at 22 m per second. The mechanical areas will be connected with a scratch-free conveying system that, combined with the automation package supplied by SMS group, will grant POSCO a quality improvement on the rolled surface of the bars and a better coil shape and formation. Further implementations are the off-line simulation process with CCT® (Controlled Cooling Technology) and quick changing system of the water cooling line in less than five minutes to grant better plant efficiency. These features will give POSCO the possibility to better supply the automotive and special steels market.

“This latest modernization project further underlines SMS group’s upgrade expertise and its position as a leading supplier of rolling mills for quality steels in all size ranges,” the release said.

The SMS Group, a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry, has some 14,000 employees. The sole owner of the holding company SMS GmbH is the Familie Weiss Foundation.
