Outokumpu Stainless AB has awarded SMS Siemag of 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.

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 16m. The maximum temperature will exceed 1200°C.

The furnaces will be designed to meet the latest environmental requirements with a special focus on low NOx emissions.

The heat-treatment line will be coupled to the plate mill by new roller tables and transfer beds enabling plates to be directly charged to the furnaces at rolling temperature. This 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.
