P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.

roll surfaces as well as accumulating fibers and other papermaking raw materials were limiting paper machines' speed and runnability. Thus, the doctor blade was invented to remove excess water and impurities, keeping roll surfaces clean during paper machine operation. Around the same time, the first rigid doctor blade holder was invented.

The flatness control in cold rolling mill is carried out through automatic flatness control (AFC). The control tasks which are to be achieved in the Level 1 closed-loop control for cold rolling mill concerns not only the thickness (AGC) but also the flatness (AFC). For a strip subject to cold rolling, the flatness is defined as the amount of ...

A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a …

Continuous improvement and statistical process control are useful, time-tested techniques—they have been used since the 1950s—but their use must be tailored to specific applications. For example, a typical manufacturing metric is parts per minute, but many roll formers should measure feet per minute. This and other tips can help roll formers accurately …

When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel and stainless steels) and non-ferrous (copper, brass, lead, etc.) integrated or electric arc furnace (EAF) steel mill of today, to small manually cranked rolling devices used at jewelers to reduce the thickness of
