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.

Robust Shape Control in a Sendzimir Cold-Rolling Steel Mill

Abstract. The shape control problem for a Sendzimir 20-roll cold rolling steel mill is characterised by operation over a wide range of conditions arising from roll changes, changes in rolling schedules and changes in material gauge, width and hardness. Previous approaches to the problem suggest storing a large number of precompensator matrices ...

Industrial History: Z-Mill, Cluster or Sendzimir Mill

Z-Mill, Cluster or Sendzimir Mill. It is common for steel rolling mills to have backing rollers in a stand, but a Sendzimir mill has nine backing rollers on each side! This allows the working rolls to exert the pressure needed to cold roll harder metals such as stainless steel without bending the rolls.

Sendzimir had little more to do with galvanizing; he wanted to concentrate on his cold mill instead. In the 1990s a modern galvanizing line bears as much resemblance to the simple steel furnace box Sendzimir built in Poland as a Harley-Davidson does to a bicycle, but at its core you will find the same physical and chemical process.
