Rolling Mill History. Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon ...
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
Our processing equipment includes a cold rolling mill, annealing furnaces, and slitting lines. Our mill enables us to hold consistent and exceptionally tight gauge tolerances, and in many cases can hold the gauge tolerance to less than half of what commercial tolerance requires. Each slitting line is dedicated to processing specific gauge ...
Brass is not as malleable as copper or silver, so it is difficult to imprint. Before rolling the brass sheets through the mill, anneal them. Place two 4 x 2-in. (102 x 51mm) 20-gauge (0.8mm) pieces of brass sheet stock on a large soldering surface.

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.
Cold rolling is a work hardening process used to change the structure of metals and is often used to process stainless steel. Cold rolled stainless steel as a raw material has a wide variety of applications in medical, aerospace and automotive engineering.
Definition of Rolling process Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. There are two types of processes. One is Hot rolled and another is Cold Rolled.
Oils, soap emulsions, fatty acids are used as lubricants during hot rolling non-ferrous metals. Mineral oils, paraffin, fatty acids are used for cold rolling. Normally, foe ferrous alloys no lubricant is used. 1.7 Rolling mill control Production of continuous sheets and strips is one of the attractive features of modern rolling mills.
