Cremona to see the world's first Arvedi ESP plant for continuous production of steel strip
Nov 1, 2006

UPDATED: Acciaieria Arvedi S.p.A. announced that they are going to build the world's first Arvedi ESP (endless strip production) plant for the continuous production of finished steel strip. This new line will be erected at the company's existing site in Cremona/Italy. Here, high-quality hot-rolled and coiled thin strip in a wide range of steel grades (e.g. HSLA/high-strength low-alloy and multi-phase steels) will be produced in an endless process from liquid steel to rolled good.

On the basis of the ISP (inline strip production) technology employed since 1992, the Italian steelmaker has developed the new Arvedi ESP process in which the cast thin slabs will be immediately rolled to strip and coiled in a continuous endless process.

The line layout can be subdivided into four main plant sections:

  • The first covers the thin-slab-caster with liquid core reduction and three high-reduction stands at the exit of the casting machine serving for in-line rolling. The strand will enter the first stand of the rougher train at thicknesses between 70 and 90 mm, whereas at the exit, it will be reduced to between 8 and 20 mm.
  • The downstream section comprises the induction furnace where the intermediate strip is equalized.
  • Subsequently, it enters the 5-stand, 4-high finishing mill for further reduction. Starting from characteristic entry thicknesses ranging, dependent on the resp. steel grade, from 12 to 15 mm, this train allows the rolling of strip to thicknesses between 12.0 and 0.8 mm at widths ranging from 900 mm up to 1570 mm. 
    Then, the strip will pass through the 70-m long laminar cooling line. 
  • The fourth section consists of the high-speed flying shear and three downcoilers.

The line is said to have a total length of 190 m.

The Italian steel producer has placed the respective order with Siemens VAI, a division of the group's Industrial Solutions and Services (I&S). The project includes the engineering, supply and installation of the thin-slab casting machine, the high-reduction mill, a pendulum shear, an inductive equalization-heating furnace, the finishing mill, cooling line, high-speed flying shear, downcoilers, electrics and automation in addition to integration and auxiliary facilities.

Simultaneously with the order placed, Arvedi and Siemens VAI have established a 50/50 joint-venture company, i.e. Cremona Engineering srl, headquartered in Cremona/Italy. The latter will not only coordinate all activities related to the implementation of this project, but also introduce the new technology to the worldwide market. Both companies will provide personnel for engineering, commissioning and maintenance of the plant as well as for training of plant personnel.

Over the next years the total planned investment in the Cremona works for the enlargement of the production capacity will be approximately 300 million Euro. Start-up is scheduled for 2008. The new single-line plant will be designed to yield an annual capacity of more than 2 million t of rolled steel.
