Product Description

               Strip Hot Rolling Mill Roll  Manufacturer Plate Hot Rolling Mill Roller

      Roll (Roller) is tool or mould for plasticizing deformation metals. It is is one of the most important parts of the rolling mill  to determine the efficiency and quality of rolling products. The plastic deformation of the rolled piece occurs through the rotating roll, and products that meet the required shape and dimensional accuracy are rolled out. Other parts on the rolling mill are set up to install, support, adjust, replace the roll and guide the rolled piece to enter the roll correctly.

 

High-speed steel (HSS) rolls are advanced metallurgical products widely used in the modern steel industry for hot rolling applications. These rolls are known for their exceptional wear resistance, high-temperature hardness, and thermal fatigue resistance. Composed of alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr) and so on, HSS rolls exhibit superior durability and performance compared to traditional cast iron and cast steel rolls.

What will you get?

1. Superior Wear Resistance and High-Temperature Hardness
• Excellent resistance to wear and thermal softening under high-temperature conditions.
• Strong resistance to thermal cracking, roll marks, and surface defects, with uniform wear ensuring consistent roll profile.

2. Stable Roll Shape and Plate Shape Control
• Advanced heat treatment ensures uniform material properties with fine grain structure.
• Roll body hardness uniformity ≤3HSD, and working layer hardness variation ≤3HSD.

3. High Mechanical Strength and ToughnessPrevents oxidation layer peeling and working layer spalling during operation
• High tensile strength (≥800MPa) with excellent impact toughness and thermal cracking resistance.
• Prevents oxidation layer peeling and working layer spalling during operation.

4. Outstanding Fatigue Resistance
• Exceptional wear resistance and fatigue performance reduce single-time grinding volume.
• Each regrinding provides an operational cycle exceeding 12 hours, with a total rolling capacity over three times that of high chromium cast iron rolls.
