Powell Equipment, Inc. Specializes in the buying and selling of used steel mill equipment on an international basis. The company''s primary areas of business are in used rolling mills for both flat and long products, arc melting furnaces, casters, and various pieces of support, finishing, processing and electrical equipment found in a steel mill.
The hot metal is passed between two rolls to flatten it, lengthen it, reduce the crosssectional area and obtain a uniform thickness. Hotrolled steel is the most common product of the hot rolling process, and is widely used in the metal industry either as an end product or as raw material for subsequent operations.
Tags Rolling Mills; What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
The PC mill was first used commercially at Nippon Steel''s Kimitsu Works in 1991 [1], and it has been commonly used in hot rolling mills for plating and stripping as a finishing mill. In the development of highly accurate and highly efficient rolling technology, the PC mill .

Apr 20, 2018· Abstract: In the metal industry, rolling is the most widely used steel forming process to provide high production and control of final product. Rolling mills must be able to change the speed of the strip at the same time that the speed is controlled within precise limits. Furthermore, this application has a severe load profile, with high torque variations during the lamination process.
This paper focuses on the various optimization techniques used in cold rolling mill process to achieve productivity and Quality of steel through literature review. Various Process models for cold rolling mills have been intensively developed in the last years, hoping to increase quality of steel strip and productivity of rolling processes.
Rolling processes 51 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (51). Fig. (51) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
Rolling strip is widely used for automobile manufacturing, food packaging, electric appliances, machinery, light industry, instruments, communications, military affairs and other fields. In cold rolling, usually no heat is applied to the work piece before forming.
4. Grinding, which is commonly used for edge preparation, including treatment of flamecut edges, removal of burrs, etc., when required. Can the end of a column, as received from the rolling mill, be considered to be a finished surface? Yes, provided the mill cut is square to the column axes and

genetic algorithm; rolling mill I. INTRODUCTION Hybrid fuzzy type controllers have been widely used in many industry fields, especially when the controlled objects are complex, nonlinear and timevarying. As an intelligent control strategy, FuzzyPID controllers have been widely used in many industrial fields due to it robustness and good
The reduced iron powder is the most widely used material in powder metallurgy industry. The direct reduction process has commonly been used by many companies (such as Hoeganas in Sweden, Kawasaki in Japan and Pyron in US) to obtain metallic iron powder by the reaction of iron oxide (magnetite, hematite ore or mill scale) and
Rolling mills were used to produce roofing iron, to flatten wrought iron billets into strips or sheets, and to divide forged bands lengthwise into reduced sections with square or rectangular cross sections (socalled cutting mills). Steam engines were first used to drive rolling mills in the late 18th century.

The problems rollingmill rolls had at the time were "the short rolling pitch, which was compromised to improve productivity, and the increasing heatload to the exterior surface of the roll." In 1988, invented the HIP Shaping Composite Ring Roll for steel bar and section mill, which was 10 times more durable than conventional rolls.
The finish cold rolling of extremely thin sheet is done by a mill dedicated to foil (4CM) or a mill dedicated to precisionrolled product (5CM) shown in Table 1. The 4CM is a 12highclustertype mill used mainly to manufacture foils mm or less in thickness. The 5CM for massproducing precisionrolled products is .
