HOT ROLLING MILLS FOR LONG PRODUCTS
Bar Mills produces semi-finished products of quality, special and stainless steels for automotive, oil and gas,
wind farms, or other special applications. They produce billets or large products round, square and hexagonal
in several dimensions and grades that cannot be processed on a continuous caster. JEC has introduced the
Roll-forge process to roll cast round blooms of up to 400 mm and 6 ton ingots to produce rounds up to 40
mm. The target is to give wider choice of sizes of finish products in order to minimize second choice of
materials thus substantially reducing transformation costs. The Roll-forge provides the similar quality
achievable by forging process, thanks to the unique features of our new heavy duty design of housing stands
capable to roll the material with reduction analogous to forging.

Sections are produced on 3-high or 2-high rolling mill stands with universal reversing or on continuous / semi-
continuous stands and over the years this technology has moved on to different solutions, such as profile
sizing process. The profile sizing system is the cost-breaking innovation in the production of H-beams (up to
600-mm height & 250-mm flange), equal / unequal profiles, special sections and all types and sizes of rails. By
combining reversing intermediate / pre-finishing rolling in a flexible reversing mill and finishing or sizing in a
separate independent universal stands, this process enhances product quality, plant productivity and
efficiency at lower production costs. The independent single finishing / sizing pass provides the best
tolerances thanks to small reductions, long life for rolls and guides, maximum roll pass design flexibility and
best finished product surface.

Our Skin-pass / Temper mills for carbon steels are available in stand-alone or in-line processing of strips in a
rolling mill plant. The advantages of Skin-pass Mills include full compliance with tight strip elongation
tolerances, excellent flatness performance, uniform surface roughness for coating applications and the
availability of wet and dry skin-passing modes. Both stand-alone and inline Skin-pass Mills are supplied in
either single or 2-stand design for adjusting the final mechanical properties, flatness, and surface finish of
cold-rolled strip. To meet the continually increasing demands for strip flatness, elongation, and roughness,
especially for hard material grades such as advanced high strength steel for automotive applications, JEC
installs 2-high and 4-high Skin-pass Mills used for rolling from soft to middle and hard grade material. They
can also be equipped with dry and wet temper modes.

COIL PROCESSING LINES
In a Color Coating Line, the strips enter the line alternately from two payoff reels and are joined by a stitcher
into endless strip. The endless strip collects in a vertical looper. Next up is a spray and brush degreasing unit
that cleans the strip surface. Then a chemical coater applies a conversion layer, followed by vertical drying.
The strip is primed in a prime coater, then goes through the first horizontal hardening furnace. As it travels
through the two finish coaters, it is coated with a top coat that hardens in the second horizontal furnace. The
next station is a vertical looper. Downstream of this is an inspection stand that checks the strip before it is cut
and wound into coils.

Our Cut-To-Length Line is able to meet customers’ demand for special steels with high strength, low residual
stress (so that memory effects are eliminated), improved flatness, tight dimensional tolerances, and high
surface quality for cutting, forming, building, and automotive applications, etc. New equipment and
technologies have been developed in the last few years, in response to the evolution of the market
requirements concerning product quality, plant efficiency and capacity to process materials with high yield
strength. The higher yield points make the leveling and the maintenance of flatness requirements more
difficult, and often this can cause damage to the leveler. It has become evident during production that, up to
now, most levelers are limited with regard to their design, control and operating facilities, which in turn is
reflected in the strip quality. These requirements involve continuous improvement of existing practices and
procedures, and the installation of new technology.

HOT DIP GALVANIZING PLANTS
The Hot Dip Galvanizing is a metallurgical process which helps to protect steel materials from corrosion caused
by potential exposure to harsh environments. This can be achieved through numerous galvanizing types and
it safeguards materials over time from degrading while maintaining their properties unaltered. The Hot Dip
Galvanizing process consists in submerging metal products in a molten zinc bath. This causes a metallurgical
reaction that bonds both metals’ external layers, creating a homogeneous and highly resistant surface.
Chosen for more than 150 years as the best means for protecting metal from deterioration, the Hot Dip
Galvanization nowadays is preferred mostly because of its versatility and sustainability. It also guarantees the
products’ longevity and an overall lower investment cost.
