ArcelorMittal Hochfeld GmbH has placed
an order with SMS Meer for the supply
of a complete high-capacity wire rod
mill with FRS® technique for high-grade
steels.
The mill’s annual capacity will be
690,000t. Of this, the major portion of the
products is expected to be cold heading
steel grades. The mill will be designed for
producing wire rod in high-grade steels
and will be in production in August 2010.
The SMS Meer contract includes a
walking-beam furnace, the mechanical
and electrical equipment of the mill
train, all of the supply systems, the
finishing facilities for the wire-rod
coils, the entire rolling and cooling
equipment, and the erection and
installation.
The walking-beam furnace for billets up
to 155mm square will reach an output of
120t/hour.
The wire rod outlet comprises a cooling
and equalising section in a loop
arrangement, a six-stand wire rod block
and a four-stand FRS® (Flexible Reduction
and Sizing) block – both in UHD
(Ultra-Heavy Duty) arrangement.
The wire-rod block and the FRS® block are
each followed by a water-cooling line.
The core component of the mill is the
FRS® block together with the cooling
and equalising section. The supply
scope therefore also includes the 104m
long LCC® (Loop Cooling Conveyor) for
forced and retarded cooling, a total of
three water cooling lines and the CCT®
(Controlled Cooling Technology) system
developed by SMS Meer.
These facilities allow wire rod to be
produced over the entire dimensional
range of 5.5mm to 25mm by means of
temperature-controlled rolling. Ultra-
fine microstructures can be achieved
especially for cold-heading grades by
thermomechanical rolling.
The maximum rolling speed for 5.5mm
wire rod will be 120m/sec.

Cropico has published an illustrated
guide on temperaturemeasurement,
explaining some common causes of
error and how to avoid them.
The guide features a series of
resistance and thermocouple
tables for user ease of reference,
while a convenient Glossary of
Terms provides an explanation
of terms relating to temperature
measurement; these include ANSI
(American National Standards
Institute), IPRT (Industrial Platinum
Resistance Thermometer) and SPRT
(Standard Platinum Resistance
Thermometer).
