Oxyfuel increases galvanising capacity
by 30%
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.
ThyssenKrupp Steel, TKS in Finnentrop, Germany produces galvanized strip for use in the automotive, white goods and for the construction industry Linde installed the ReBox oxyfuel solutions in the existing galvanizing line, which resulted in a production increase of 30%, from 82 to 105 tonnes/h

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.
Gas solutions for business growth
Linde Gas will demonstrate its range of proven and viable solutions for the iron, steel and metals industries at the parallel GIFA, METEC and THERMPROCESS fairs in Germany, 12-16 June 2007.
Since oxyfuel not only effectively heats, contributing to a reduction of fuel consumption, it also cleans, thus eliminated the need for the pre-cleaning section.
Direct Flame Impingement (DFI) oxyfuel, where the oxyfuel flames are fired directly onto the moving metal was the chosen ReBox solution.
This drastically increasing the heat transfer for more throughput without extending the furnace or line.
Three meters of the recuperative zone were refitted with a compact 5MW DFI oxyfuel unit consisting of four burner row sets.
Fuel consumption was reduced by 6% and annealing properties over the entire strip width were improved.
The strip surface was effectively cleaned from unwanted contaminants such as oil and residues, making it possible to remove a 25m strip pre-cleaning section.
More detailed results will be presented by TKS at the "InSteelCon 2007" at the international steel fair METEC in Duesseldorf, Germany, in June.
Linde has made over 100 oxyfuel installations internationally in reheating and annealing furnaces, resulting in increased furnace capacity, more flexibility and reduced costs for the steel industry.
