Silva Mash, one of the largest welded tube producers in Bulgaria, has ordered a new high-productivity ERW line from Danieli. The line will be used to produce niche tubular products mainly for high-end automotive and furniture applications.
Silva Mash produces 60kt/yr of high-quality tubes delivered to the main European automotive and furniture manufacturers.
According to Danieli, the W+K ERW 45/2.5-150 mill is designed to produce round, rectangular, square, semi-oval and elliptical high-quality and high-strength tubes with superior surface finishing, ODs ranging from 10mm to 45 mm and WTs from 0.5mm to 2.5 mm.
With a velocity reaching 150 m/min, the new line can offer superior diameter/wall thickness ratio capability which, along with quick product change-over time – less than 60 mins – results in great product flexibility, Danieli claims.
"In order to achieve the high level of productivity requested, the line is composed of an entry line with a double decoiler, strip joiner, horizontal accumulator, heavy duty forming section with break-down, fin pass, welding and sizing stands, a cut-off and evacuation system including a packaging machine," says Danieli.
