An oxyfuel that heats by direct flame and cleans, has boosted galvanizing capacity by 30% and resulted in removal of the 25m strip pre-cleaning section at a German steel plant.
Pit furnace fuelling to raise mill capacity
Four pit furnaces at a French steel rolling mill will in a performance guarantee contract, during 2007-2008 be converted into full oxyfuel operation to boost the rolling mill capacity.
The furnace will be the third such oxy-fuel fired type to be used in Hofors.
The earlier installations were made in 1997 and 1998 and were later both upgraded to flameless oxy-fuel operation.
Ovako is a leading European, long special steel products company.
It annually supplies 2 million tonnes of low alloy and carbon steel to the rolling bearing, heavy vehicle, automotive and engineering industries.
The first installation of oxy-fuel in a reheat furnace at Ovako was made by Linde 13 years ago.
Since then the majority of the furnaces in Hofors have been converted into 100% oxy-fuel operations.
Linde reported that Rebox produces 35% increased heating capacity and 35% less fuel consumption.
Rebox flameless oxy-fuel operation additionally leads to low NOX emission and high temperature uniformity, said the company.
* Wind mill market - the new rotary hearth furnace will play an important part in Ovako's production of materials for the growing wind mill market.
The Gases Division of The Linde Group will deliver a turnkey installation project, including guaranteed capacity, emission levels and quality.
Commissioning is scheduled for February 2009.
Rebox oxy-fuel systems are now used in over 110 reheat and annealing furnaces.
The use of oxy-fuel will further improve important parameters such as fuel consumption, throughput capacity, and emission levels.
When compared with air fuel systems, oxy-fuel can boost production throughput up to 50%, equally reducing fuel consumption and CO2 emission by 50%, said Linde.
* About the Linde Gases Division - the Linde Group is a world leading gases and engineering company with more than 50,000 employees working in around 100 countries worldwide.
Following the acquisition of The BOC Group, the company has gases and engineering sales of approximately EUR 12 billion/year.
