Outokumpu Stainless
orders heat-treatmentline for flexible and energy-efficient heat treatment of
stainless steel plates
Outokumpu Stainless
AB has awarded SMS Siemag, Germany, a
contract for the supply of a heat-treatment line for stainless steel plates. This
expansion will allow the Outokumpu Stainless works in Degerfors, Sweden, to boost its production
of heat-treated plates and improve the product quality. The new equipment will
start operation in 2013.
SMS Siemag’s supply includes two heat-treatment furnaces
with the relating handling machinery, a roller quench as well as the electrical
and automation equipment for these facilities, plus the integration of the heat-treatment
line into the upstream and downstream operations.
The two heat-treatment
furnaces will be specifically tailored to the wide product portfolio of
Outokumpu Stainless. The furnaces will
be capable of heat treating plates with a maximum length of 16 m. The maximum
annealing temperature will be above 1,200’’C.
The furnaces will be designed to meet lalest environmental
requirements with a special focus on low NO emissions.
By coupling the heat-treatment line with the rolling mill by
new roller tables and transfer beds, plates can be directly charged into the
furnaces at rolling temperature. The makes the heat treatment much more
energy-efficient.
The new roller quench is capable of cooling two plates at a
time and independently of each other.
For the electrical and automation system SMS Siemag supplies
the complete drive systems including frequency converters and MCC (Motor
Control Center) as well as the level 1 system. This includes, among others,
the tracking system and the visualization of the processes in the HMI (Human
Machine Interface). As SMS Siemag is
currently also supplying the automation system for a new 9/5 cold plate
leveler, the whole area will eventually operate with X-Pact automation.
