2003年2月13日 · Shape control equipment—flatteners or levelers—generally is the heart of most manufacturer's or service center's coil processing and feeding lines. Don't overload it. Use proper settings. Maintain it. Align it properly. Keep it clean and calibrated.

Tension levelling is an effective tension-assisted levelling method. The coil is put under significant tension between pull and drag bridles placed before and after the specially designed roller levelling device (see Figure 8). With tension levelling, all parts of the metal are pulled past the yield point, top to bottom, edge to edge.

2002年10月10日 · Flatteners or levelers can't reduce crown significantly because their work rolls are offset. It takes a rolling mill with opposed rolls to do that. This article discusses the causes of crown, but not how to eliminate it.

2003年1月16日 · A leveler, in the neutral setting, like a backed-up flattener, can eliminate surface-to-surface length differentials such as coil set and crossbow. Edge wave and center buckle are edge-to-edge length differential problems.

Tension levelers level material by stretching it into plastic deformation. In order to achieve the high amounts of tension necessary, a tension leveler utilizes bridle rolls to isolate tension for leveling. The bridle roll design also allows for controlling tension at upstream and downstream coilers.

Tension levelers are one of several forms of shaping equipment that can be used on metal roll and coil feeding, cutting or slitting lines. The main purpose of a tension leveler is to help either preserve or improve the uniformity and sizing of the coil material as it proceeds through a feeding, slitting or cut-to-length line.

BOYA Tension leveler is the core equipment to leveling and shaping strip in cold rolling mill various process lines such as pickling line/pickling and tandem mill, Continue annealing line, galvanizing line, tinning line, color coating line, finishing lines etc.

Our patented e-Drive® technology employs tension leveling techniques for gauges .010" to 1". With today's laser cutting machines in widespread use, erasing the footprint of internal stresses in flattened metals has become more important than ever.

As a Clecim’s client, your expectation will be reach by the best technologies for Tensions Levelers. The purpose of the tension leveling stand is to improve your product flatness by stretching all of the longitudinal structures in the metal strip to equal length.

Tension leveling is the process of pulling the strip beyond its yield point to permanently change the shape of the strip and make it flat. The material is run through an entry and exit set of bridle rolls, with the corrective leveler located between them.
