This case study demonstrates the use of the LQG design tools in a process control application. The goal is to regulate the horizontal and vertical thickness of the beam produced by a hot steel rolling mill. This example is adapted from [1]. The full plant model is MIMO and the example shows the advantage of direct MIMO LQG design over separate ...

Drives in steel and rolling mills are exposed to extremely hard demands. Glowing steel, alternating operational modes and overloads spell out a high level of electrical and mechanical strain that calls for very sturdy designs. As a traditional supplier to heavy industry, VEM has developed over decades into a specialist for rolling mill drives.

A Steckel mill can also come with two rolling stands as a twin-stand Steckel mill. Similar to the conventional single-stand Steckel mill the twin-stand Steckel mill operates also in reversing mode, but with fewer reversing passes. It provides you with a capacity of 1.0 to 1.2 million tons per year. If a roughing stand is integrated in the ...

This demo shows plant modeling and controller design for a multi stage rolling mill process. Sheet Rolling Mill processes involve progressive thickness reduction of continuous sheet metal in multiple stages. Some of the control variables of interest are exit thickness, throughput and the tension in the sheet as it passes from one stage to the ...

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.

For the first year the mill was not producing iron but was rather exclusively re-rolling rails. Due to the softness of the iron, rails wore out in two years or less and had to be returned to the mill and re-rolled. Shortly after, the company began manufacturing iron and was manufacturing and re-rolling 30,000 tons of rail per year.

When using a rolling mill, the sheet should be supported in one hand, whilst the other turns the handle, thus drawing the sheet through the rollers. The sheet should be caught as it comes through, and its thickness checked using a vernier/calliper. Then, using a rolling mill machine again, re-roll your sheet to achieve the required thickness.
