Hot Rolling

In the hot rolling mill (Figure 21), the so-called billet is heated up to 400°C or to 600°C at the pre-heater depending on the type of alloy. After passing through the reversing hot rolling or "break down" mill, the material is fed through a number of non-reversing tandem mills (400–550°C) where the thickness of the strip is set ...

Metal Rolling

The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.

Hot Rolling

Hot rolling is a metalworking process in which metal is heated above the recrystallization temperature to plastically deform it in the working or rolling operation. This process is used to create shapes with the desired geometrical dimensions and material properties while maintaining the same volume of metal. The hot metal is passed between …

What Is A Rolling Mill?

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. If the temperature of the ...

Rolling Mills Selection Guide: Types, Features, Applications

Hot rolling mills are used in applications where large piece of metal, often including slabs or billets, are heated above their recrystallization temperature. Once heated, the metal is deformed between the rollers to form thin cross-sections. Due to recrystallization, hot rolling mills reduce the typical grain size of a metal, while still ...
