A robust controller is designed for looper systems in hot strip mills in order to solve the problem of tension control. This kind of control action has robust performance, which is suitable for complex looper systems. For the particular mode, the corresponding existence condition of the controller is obtained by applying Lyapunov function approach and the linear matrix inequality …
Hot Rolling • Ingots are reheated and bloomed to slab • Slabs are reheated and rolled to bar • Bar is fed directly to a hot rolling mill • Types of hot rolling mills – Continuous mill (hot strip mill) – Reversing mill – Steckel mill (reversing mill with integral coil heating stations on either side)

Hot strip cooling temperature and its cooling rate is get by strip cooling system and coiling temperature of hot rolled strip is an important parameter on its performance index. It presents laminar cooling system of the 700 mm hot strip mill and the mill rolling process is present, the laminar cooling system is analyzed on the rolling theory and techniques.
Rolling is a metal forming process in which metal stock is passed through a pair of rolls. There are two types of rolling process - flat and profile rolling. In flat rolling the final shape of the product is either classed as sheet, also called "strip" (thickness less than 3 …

In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.

Hot rolling is an essential process in steel strip production. Rolls are key components in hot strip mill (HSM). Work and backup rolls have to withstand adverse service conditions in hot-rolling process, such as high thermal stress, heavy mechanical stress, and long service periods, resulting in serious wear and fatigue on roll surface.
In this paper, a robust steering control is proposed as a means to guarantee the stability of a hot strip finishing mill and improve its performances. The aim of the rolling process is to obtain a metal strip which is uniform and at the desired thickness. The lateral movement of the strip may reduce the quality of the product and damage the rolls.

and process automation systems for hot-strip mills are the reduction of strip-width deviations and the avoidance of below-minimum widths after the finish-ing mill, which is why Primetals Technologies has devel-oped model-based strip-width control. Recognizing that tension can be used to manipulate the strip width in the
In continuous hot-dip galvanizing lines, cf. Fig. 1, the strip—subject to tension and high temperatures—may be plastically bent at the deflection rollers of the plant. These repeating bending actions cause deviations of the strip from the ideal flat shape in form of a coil-set or a crossbow. Here, the terms coil-set and crossbow

Simulations on a detailed nonlinear model of the full process controlled by MPC indicate it is feasible, and can lead to considerable performance improvement. This paper reports on the control of mass flow using MPC. The process to be controlled comprises six mill stands, six main drive speed control systems and the existing PI based flow rate control system.
3. PROCESS Rolling mills consists of different type of Mills based on the desired products namely: A. Long Product Mill a) Light and Medium Merchant Mill/ Bar Mill. b) Wire rod Mill. c) Medium merchant structural mill/ Structural Mill. B. Flat Product Mill a) Plate Mill b) Hot Strip Mill A.

S MIE AG Hot Flat Rolling Mills 2 SMS Siemag does not treat descaling as an isolated measure but as an integral part of the process chain from continuous casting through hot and cold rolling up to final strip processing. Strips with an excellent surface quality can be produced only if well-tuned measures are taken in all process steps.

The hot strip mill includes a pair of coilers immediately downstream of and adjacent the finishing train. The coilers are vertically aligned and on opposite sides of the pass line. The strip coming out of the last finishing stand is immediately coiled in one of the vertical coilers, while the other vertical coiler may simultaneously be uncoiling and directing a previously rolled strip along ...
from the rolls, the process is called simple rolling. 1.2 Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling. 1.2.1 Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature.
