Shape control systems for Sendzimir steel mills - IEEE ...

Such mills, with a variety of shape actuators, offer the control engineer considerable choice in the configuration and design of a shape control system. In addition, the Sendzimir mill is a reversing mill, with shape measurement devices at either end of the mill, providing a facility for feedforward of incoming shape disturbances.

Tytus

May 23, 2013· John Tytus, the story goes, balked: "As long as I'm in charge of the Armco rolling operation, there will be no Sendzimir mill in Armco plants." Doc Hayes phrased it another way: "Put a Z-mill in or find another Director of Research." Gurney Cole, an Armco manager and one of Tad's champions, kept pushing.

Sendzimir process - Wikipedia

Sendzimir process (named after Tadeusz Sendzimir) is used to galvanize a steel strip by using a small amount of aluminum in the zinc bath and producing a coating with essentially no iron-zinc alloy.The process guarantees high resistance and durability characteristics. About 75% of hydrogen was needed in the original Sendzimir process but all the newer nonoxidizing …

Static Model Identification for Sendzimir Rolling Mill ...

Aug 17, 2020· A Sendzimir rolling mill (ZRM), one of the rolling mill systems, is a machine used to obtain a steel strip with a desired shape in cold rolling. Model based controllers are mainly used for the shape control, but it is difficult to obtain the mathematical model of the ZRM, so model identification should be used. This study proposes a method identifying static model of the …

The other major new facilities coming up at the Salem steel plant include electric arc furnace, ladle furnace, AOD convertor, slab caster and a new sendzimir mill.These equipment are expected to help add 0.18 million tonnes of stainless/alloy steel products in the SAIL product kit.

Cold Mill Systems | TMEIC

A Cold Mill rolls coils of pickled steel from the pickle line at ambient temperature, using coolant oil. The cold mill produces steel and stainless steel and is also used for aluminum, aluminum foil, and copper. There are several types of mills such as 2-High, 4-High, 6-High, 12-High, 20-High, and Sendzimir Mills that have a variety of types of flatness control operations.

[PDF] Shape recognition performance analysis and ...

Twenty-high Sendzimir rolling mills (ZRMs) typically use small diameter work rolls to provide massive pass reduction. Because of the small diameter of the work rolls, a rolled steel strip has a complex shape mixed with quarter, edge, and center waves. When the strip shape is controlled automatically, actuator saturation occurs in the shape actuator such as AS-U rack.

Z-mill - Wikipedia

A Z-Mill or Sendzimir Mill is a machine for rolling steel. Unlike a traditional rolling mill this 20-high cluster mill configuration utilizes cascaded supporting rolls to apply force on the small work rolls in the center. This allows the application of a higher roll pressure without bending the work rolls, which would result in poor metal quality.
