Wire Journal News

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.
