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 ...

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 ...
Metal Rolling
Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing ...

Hot Rolling
When hot rolling steel in the laboratory, using relatively small rolling mills, values of 4–20 kW/m 2 K appear to be the correct magnitudes. If modelling hot rolling of steel under industrial conditions, values of 50–120 kW/m 2 K are more useful. In both cases, the layer of scale is an important parameter.
What is Hot Rolling – Advantages and Disadvantages
This reduces the pressure requirements. Disadvantages of Hot Rolling: 1. Expensive Process: Hot rolling is an expensive process because it requires expensive tools, great skill to handle and maintain it. 2. Correct Temperature Difficult to Maintain: The correct temperature range for working is difficult to maintain.

Hot Rolling vs Cold Rolling
Hot Rolling. Cold Rolling. The material to be rolled is above its re-crystallization temperature. The material to be rolled is below its recrystallization temperature. The roll radius is larger than used in cold rolling. The roll radius is smaller. Heavy reduction in area of the work-piece can be obtained.
