Examining tube mill roll tooling, setup, and maintenance. Poor tooling setup and mill alignment can be costly, especially when they result in decreased production quality and scrap. Both areas must be maintained continuously. A secret to achieving maximum roll integrity is simple, but often forgotten: Roll tooling design is based on known ...
Roll Forming Tolerances. 2.Bow. The vertical plane deviation from a straight line can be a cross or longitudinal bow, it is caused by uneven vertical gaps on symmetrical cross-sections and uneven forming areas on asymmetrical sections in the general bow can be held to plus or minus 1/8 inch in 10 feet or 3mm in 3 meters.

Design the Layout and Roll Tooling After completing the flower, you need to choose drive diameters and check for maximum flange roll sizes and possible interference with the rolling mill. During the design phase, you'll need to consider increasing the pitch diameters of the rolls from pass to pass (also called step-up).

Knowing that the importance of the perfect tube and pipe roll design is so critical, Roll-Kraft developed its own proprietary roll tooling design software in 1985. It was created so that we can build the best possible tooling for you. It combines proven design practices and experiences gained since the company was founded in 1963.
The mill reservoir should be placed close to the mill and use larger-diameter pipe over shorter distances to provide the least change in coolant pressure from the pump to the mill. A rule of thumb with plumbing is to maintain the largest required plumbing diameter as long as possible when carrying coolant to the mill because any reduction in ...
On a tube mill the hammer is the first pass top breakdown roll. Effectively the first pass rolls lift the center area of the strip upward. This draws the outer edge areas inward toward the center and allows the top roll to form two deep edge area curves into the strip.

A good roll design considers the dynamics of girth growth vs reduction and the subsequent edge distortion when determining the correct roll contour and fin angles. Reduction and Girth Control: The fin blade is a narrow roll segment that fits into the …
Roll Form Tooling - Innovative Automation. As important as a Fin Mill is to the production of a quality fin, the Roll Forming Tool or Fin Tool might be even more important. This tooling is largely responsible for all of the quality aspects of the fin being produced including the height and the final fin density.

It is successful with Tig and Laser welding and with two-roll weld boxes of any weld type. A peaked fin pass design is used when there are no side roll passes between them, as occurs on large pipe mills. In years past, the old design, low-frequency welders liked a peak tube to ensure good electrode contact, but that is not really needed.
The new range of Henry Simon MIlling equipment captures the original pioneering spirit combined with the groundbreaking design and aesthetics resulting from ...
W or Reverse Bend Style Rolls. Reverse bending is a variation of edge forming. It is a technique as old as metal forming itself. It's as simple as lifting or reorienting a piece of metal so that a hammer blow strikes it more advantageously. On a tube mill the hammer is the first pass top breakdown roll. Effectively the first pass rolls lift ...
In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.

The design options we use are usually a result of collaboration between the roll designer and the roll buyer which should also include shop floor management and/or mill operator preferences. Technical considerations always include the physical properties of the metal being formed, the tube size with respect to mill size, and the mill configuration.
