What is Forged Steel Roll


Through smelting, forging and heat treatment, the forged steel rollers make the working layer of the roller body have uniform high hardness, high wear resistance and excellent accident resistance. At the same time, it is ensured that the roll neck and the core of the roll body have a certain strength and high toughness.

This unique property of forged steel rolls gives it an irreplaceable advantage over cast rolls in cold rolling and non-ferrous rolling.

According to the conditions of use, forged steel rolls can be divided into hot forged steel rolls and cold forged steel rolls.

Forged steel hot rolling rolls are mainly used for hot rolling blanking and profile steel roughing rolls, while forged steel cold rolling rolls are widely used for cold rolling rolls.

The use of forged steel cold rolling rolls is demanding. The surface of the roll body must have high and uniform hardness to ensure the dimensional accuracy and good surface quality of the cold-rolled strip or steel plate. The roller body has a certain depth of hardened layer and has high accident resistance. For this reason, the requirements for the original structure of the roll are very strict, one is pure metallurgical quality, and the other is the uniformity of the structure.

At present, cold roll materials containing about 2% chromium are mainly used, and the working layer above HS90 is about 10mm. For the newly developed Cr5 series cold rolls containing 5% chromium, the working layer above HS90 is above 30mm. The excellent performance of Cr 5 series cold rolling work rolls in all aspects will gradually replace the traditionally used Cr 2 series cold rolls and become the development direction of cold rolling work rolls.

Product advantage

The world No. 1 in crude steel production steel plant, over 70% of the HSS for bar and wire are from us.

LMM high-speed steel rolls have higher steel passing per groove (times) due to their good wear resistance, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, and improve the overall efficiency of the factory.
Generally, the amount of steel passing in a single groove (times) is 3 to 5 times that of cast iron rolls.
