WORKING ROLL

Forged steel work rolls, which alter material properties at ambient temperatures, represent the most susceptible spare components to wear during strip rolling processes. By employing materials with varying chromium content—such as 2%, 3%, and 5% chromium—we can significantly enhance roll quality and service life to meet diverse customer requirements.

INTERMEDIATE ROLLS FOR 6HI MILL

Forged steel intermediate rolls are primarily employed in high-precision six-roll mills (and certain eight-roll mills), deriving their name from their position between the work rolls and the support rolls. Their principal function is to control the strip profile during the rolling process. Depending on the required hardening depth, materials such as 2% chromium, 3% chromium, 5% chromium, and semi-high-speed steel (SSH) may be utilised.

SENDZIMIR ROLL

Senjimir mills are favoured by certain high-end users for their superior rolling speed and precision, being employed for rolling ultra-thin strip, silicon steel, stainless steel and similar materials. The rolls for Sendzimir mills are fabricated from tool steel, grinding tool steel, and high-speed steel. During manufacturing, elevated quenching and tempering temperatures are typically required. To achieve the specified hardness, secondary tempering is necessary. The product hardness ranges encompass: 55-60 HRC, 60-63 HRC, 61-64 HRC, and 63-66 HRC.

BACK UP ROLL

Forged steel supports are primarily employed in four-roll and six-roll mills, with roll diameters ranging from 350mm to 1600mm. Commonly used materials include 9Cr2Mo, 86CrMoV7, 70Cr3Mo and 45Cr5NiMoV.
