Marking of metal sheathed tubular elements with rating, voltage, type number etc, directly after the reduction of the tube is desirable from production point of view. Marking the tubes without intermediate handling means less operation cost and less danger for mix-up of elements.
GRANLUND KOP marks the reduced element along the element (parallel to its length axis), while KBP marks around the element (circumferential). Both are based on pressing steel types into the sheath and are mounted on the reducing rolling mill.
The KOP is available in two versions: KOP-15 with 1,5 mm types and KOP-25 with 2,5 mm types.
• Smooth operation in line with KOR
• Flexible for different tube diameters
The marking and supporting rolls are mounted in a frame attached to the roll reducing mill and can be mounted on old as well as new mills. The tube with-drawing device is attached to the marking equipment instead of the end plate of the bearing box assembly.
The type is mounted on a round type-holder. The reduced tube is pushed through the marking device by the rolls in the reducing rolling mill. It is automatically marked by the round type-holder which rotates to the end of the marking and then idles. When the tube has
passed, the type-holder automatically returns to its starting position.
The tube is supported by a supporting roll when being marked, avoiding bending of thetube.
The type holder can be changed in 2-3 minutes.
