Process for steel strip gas wiping using
Nitrogen
Linde gas announces a breakthrough process for steel strip gas wiping using nitrogen, which will be on show at Tube 2008, the International Tube and Pipe Trade Fair, in Dusseldorf
This new process reduces nitrogen consumption by up to 50% compared to other patented methods using nitrogen Surface wiping with nitrogen is quickly gaining popularity among automotive body strip producers, due to its smooth finish and superior look and feel when painted

"Our new process significantly improves surface wiping quality in continuous strip annealing and galvanising lines compared to conventional solutions using air," according to Akin Malas, Project Manager for heat treatment in the applications development department at Linde Gas.
"The Linde improved nitrogen wiping application is most appropriate for medium to large size steel strip manufacturers in the semi-finished segment, as well as in integrated iron and steel works," he added.
Nitrogen wiping provides a smooth surface finish and makes higher line speeds possible.
This quality improvement comes at half the cost of current nitrogen wiping processes, due to a significant reduction in nitrogen consumption.
Linde is currently exploring partnerships with wiping knife manufacturers in order to further develop and commercialise this new technology.
There are currently plans to offer a complete solution including heat treatment services for the furnace atmosphere, such as strip heating and annealing.
