Status of forged steel rolls

Forged steel rolls can be divided into forged steel hot rolls and forged steel cold rolls. Forged steel hot rolls are mainly used for hot rolling and section steel roughing rolls, and forged steel cold rolling rolls are widely used as cold rolling work rolls. Due to the high quality requirements of cold-rolled sheets, especially […]

cast iron roll

Generally classified by manufacturing process: The roll whose working layer is white-faced structure (matrix + carbide) due to the chilling effect of the metal type is called chilled cast iron roll.Cast iron rolls use the above method, but appropriately increase the carbon content of molten iron to obtain a hemp structure (matrix + carbide + graphite), […]

Mill rolls classification

There are many types of rolls. At present, the commonly used types of rolls are cast steel rolls, cast iron rolls and forging rolls. There are also a small amount of carbide rolls on the profile rolling mill. According to the molding method: casting rolls and forging rolls; casting rolls refer to the types of […]

Different Types of Rolling Roll Mills used by Steel Roll Manufacturers

The rolling process is the most common industrial process, which is used for making large length cross section like sheets and plates of steel and aluminum for structures. Rolling mills are used for completing the rolling process. These are available with various steel roll manufacturers in a variety of shapes and sizes as per requirement of the […]

Metallurgy of Rolling mill Rolls

Mill Roll classification summary

Classification of pressed metal types Rolling steel products are called black rolls. Rolling non-ferrous metal materials (copper, aluminum, etc.) products are called non-ferrous rolls.   According to the temperature of the rolled material when it is rolled The rolling temperature higher than the recrystallization temperature of the rolled material is called hot rolling, and the corresponding roll […]
