Block diagrams of the production line are shown in Figures 3 and 4. Electricity is. primarily used to operate the rolling mill and electric arc furnace. The electric arc furnace uses.
I claim: 1. In a rolling mill looper control system for controlling a looper arm supporting a looper roller adapted to engage a strip of material to be rolled from a first roll stand to a second roll stand, including a direct-current looper motor for applying torque to said looper arm; a speed regulator for adjusting the speed of at least one of said first and second roll stands to provide a ...
A tandem rolling mill is a rolling mill with two or more close-coupled stands, each of which is setup for rolling using the spring curve and the compressive curve of the metal so that both the rolling force and the exit thickness of each stand are determined.. The main advantages of a tandem mill are: only one single pass is required which saves time and increases production; …

A typical one of conventional systems of the type as described above is illustrated in FIG. 1. Referring to FIG. 1, reference numeral 1 designates a rolling mill of a No. N stand, 2 another rolling mill of a No. N+1 stand, 3 a work or material to be rolled (this advances in a direction from the No. N to the No. N+1 stand), and 4 an electric motor for driving rolls of each of the rolling …
billet or bloom by diagonal rolling with the subsequent elongating of the hollow semi-finished product on the Pilgrim tube-rolling mill [44]. Therefore, the main objective of this paper is the construction of three continuous cooling transformation diagrams for an HSLA steel intended for the seamless tubes production.
5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.
2 Dynamic model of the hot-steel rolling mill The diagram of the hot-steel rolling mill system is given in Fig. 1. The following parameters can be defined [1, 9]: θ is the looper angle, ω is the looper angular speed, Rl is the looper arm length, h
The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
In order to improve the disturbance rejection ability and tracking accuracy of the hydraulic servo system of the rolling mill, this study combines nonsingular terminal sliding mode control (NTSMC) with active disturbance rejection control (ADRC). A fourth-order extended state observer was designed to estimate the disturbance of the system in real time.
for rolling. They are then rolled to smaller thickness by passing over a series of rolls, and finally made into a rolled coil of steel. The coil is shipped or sent to a cold mill. The cold roll mill reduces the thickness further. Annealing and galvanizing is done on the steel to meet the specifications of its intended use.
James L. White, Kyonsuku Min, in Comprehensive Polymer Science and Supplements, 1989 9.3.2 Two-roll Mills. The two-roll mill was used in industrial operations of various types well into the dimmest past.It was, however, only with the 1836 patent of Chaffee 31 that roll mills began to be used in the polymer industry. Chaffee 32 sought to use roll mills and calenders in place of …
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …
FIG. 1 is a schematic block diagram of the electrical circuitry for controlling a rolling mill in accordance with the teachings of the invention; FIG. 2 is a functional block diagram of the rolling mill control system of FIG. 1;
The electrical conductivity of the samples was measured at eddy current structuroscope (Scientific Research Institute of Introscopy "Srektr", Russia) at 9 points in parallel and perpendicular to the rolling direction (Fig. 2b). The final value was determined as the average value of measurements at all points.
rolling mills (8 stand roughing rolling mill, 4 stand intermediate rolling mill, and 4 stand finishing rolling mill) was built by Morgan-Sumitomo Heavy Machinery Co. Ltd.. In the 1980s, the aimed qual-ity of products was shifted toward high-value-added special steel quality, and, to achieve this, in 1986, a three-roll finishing rolling
The rolling experiment is implemented by a four-high experimental rolling mill, shown in Fig. 9(a). Diameter and roll body length of the work roll for the experimental rolling mill are 170 mm and 400 mm, respectively. For the backup roll, both are 400 mm. All samples after rolling do not show buckling deformation and are shown in Fig. 9(b).
