25 mm bar produced on March 29, 2015 at the rebar and wire rod mill of Silat
Successful startup for Silat´s rebar and wire rod mill
On Tuesday, March 24th, the first billet was rolled on
the bar and wire rod mill of Silat (Siderúrgica Latinoamericana),
located in Fortaleza, Brazil. During the day,
many billets measuring 130 mm x 130 mm x 12,000 mm
were rolled and the 20mm bars were discharged onto
the cooling bed. Hot testing progressed quickly in the
following weeks with 25mm, 16 mm two slitting and
10mm bars, using the 4 slitting scheme.
The rolling mill is fed by a 90 tph walking hearth reheating
furnace. The plant layout includes a 20-stand
continuous mill with two outlets, one for straight bar
and the other for wire rod in coil. The rod outlet includes
a one 10-stand, high-speed twist free finishing
block fed from the bar mill finishing stands. The smaller
bar sizes are produced on four strands, to take advantage
of the mill´s capacity for the entire product range.
