Andreas Sieber, Head of Operations, Plant 1, at Steeltec:
“The transition from chemical treatment to mechanical descaling had a range of positive effects on operations here in Emmenbrücke. In addition to much more straightforward waste disposal, we’ve also noticed the wire surface is now much better prepared for the drawing process. Depending on blast media type and size, the blast process creates little pockets on the surface, which improves adhesion and distribution of the drawing oil. This is incredibly important in order to achieve the desired drawing quality and to extend the life of drawing dies. Compared to immersion baths, blast machines also take up less room and fit snugly into the drawing line."
Depending on drawing speed, wire or rod diameter, material and desired surface cleanliness, FL machines can be equipped with three, four or six blast wheel units with a range of motor capacities. The machines are slotted into the line ahead of the drawing machines and fetch relevant settings and parameters from the latter.
Dirk Meyer, Project Engineer, Plant 1: “Over the years, the FL machines have proven their reliability, sturdiness and, not least, their high performance. We continuously modernise, renew and upgrade our drawing technology and know that there’ll always be a Wheelabrator machine that can keep up with latest requirements.”
More than 600 FL blast machines have been manufactured to date and are in operation in wire and rod production around the world.
