The Z-Mill or Sendzimir Mill is a machine for rolling steels. 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.

The rolling of hot steel slabs using a Sendzimir mill requires a much smaller operational area than a continuous hot strip mill. This milling process is not recommended for heavy-duty running surfaces such as crane rail. However, since the strip steel is not preheated, it enters the reduction furnace, which undoubtedly increases the heat load ...

Vibration frequency and torque were measured for the Sendzimir mill at the Chiba Works of Kawasaki Steel Corporation. As a result, it was found that the generation of chatter mark is caused by the fluctuation of torque due to the stick slip between rolls and by the peripheral speed difference between the upper and lower work rolls.

Sendzimir's contribution is known and respected in the industry; still, in textbooks you can read about the Sendzimir mill but never about the Sendzimir galvanizing method. No one thought to call it sendzimirizing. One reason is that Sendzimir just liked playing with mills and machines better, and that's what he spent the rest of his life on.
