The memorizing of free rolling torque T r must follow the following sequence: − The billet has been threaded in n-th stand. − The billet is not threaded in the (n+1)th stand and has not entered the guide of (n+1)th stand. − The rolling torque of billet in (n-1)th stand has been regulated to a free rolling status.
USSM currently owns 8 rolling mills of three different configurations: 1 high-tech advanced 20-High mill, 2 Four High mills (H-mill), and 6 Sendzimir mills (Z-mill). H-mills are the simpler of the two, and use two large diameter work rolls which are driven and supported by a set of back up rolls situated atop and below, hence four high.

Introduction. AC adjustable-speed motor drive systems have been established as the preferred. technology for new rolling mill installations and extensive modernization projects. The AC adjustable-speed motor drive system provides metals mills with many advantages compared to traditional DC drive technology, including: Improved drive effi ciency.
Roughing Mill Wedge and Camber Control — The roughing mill has the task to transform the incoming slab into transfer bar with typical quality parameters of: • Uniform thickness <1.5%. • Wedge in cross-profile <0.5%. • Camber (straightness) <50 mm. Thickness accuracy and wedge control must be done in most roughing mills without any thickness
To ensure product uniformity, hot rolling mills need reliable, repeatable process control data to identify operating issues; off-gauge and off-tolerance product results in the downgrading or even scrapping of coils. However, when hot material exits the rolling mill, the vertical position and orientation of the strip is not sufficiently defined ...

It is estimated that the yield of steel from molten steel to coil can reach 98.0% - 98.5%, while ISP process is only 96.5%; ④ It can produce high-quality ultra-thin strip steel ...
What Is a Rolling Mill? At its most basic principle, a rolling mill is a machine that reduces the thickness of a metal without sacing any of the material – meaning material is always displaced and never lost. By design and function, rolling mills do not generate scrap. The process of rolling affects the materials at a metallurgical level ...
