Finished & Pre-Finished Stand HSS Roll

Availability:
Quantity:
High speed steel as an advanced technical roll material, is an important revolution of the modern steel rolling industry. Due to its unique features, it significantly increases the roll pass life, saves roll changing time, reduces roll comsuption and improves the overall benefits of the steel mills. HSS rolls, always as the first rolling solution choice, are widely used in wire & bar mills as well as plate and strip mills.


Product Summary


The High Speed Steel Roll Ring is a high-performance component that has become a staple in the metal rolling industry. It is designed to offer a perfect balance between strength, durability, and precision. The roll ring is manufactured using state-of-the-art techniques and high-quality raw materials, ensuring its superior performance in even the most demanding rolling environments. With its advanced design and engineering, the High Speed Steel Roll Ring is capable of delivering consistent and reliable results, time after time.



Key Features


Advanced Heat Treatment

The heat treatment process of the High Speed Steel Roll Ring is a critical step in its manufacturing. It undergoes a carefully controlled heat treatment cycle to achieve the optimal microstructure and mechanical properties. This results in a roll ring with enhanced hardness, wear resistance, and toughness. The advanced heat treatment also improves the roll ring's ability to withstand thermal cycling, reducing the risk of thermal fatigue and extending its service life.

Rigid Construction

The High Speed Steel Roll Ring is constructed with a rigid design to ensure its stability and performance during operation. The robust construction helps to resist deformation under high loads and speeds, maintaining the roll ring's shape and accuracy. This rigidity also contributes to the roll ring's ability to handle heavy-duty rolling applications with ease.

Excellent Surface Finish

The surface finish of the High Speed Steel Roll Ring is of the highest quality. It is ground and polished to a smooth surface, which not only reduces friction but also improves the quality of the rolled products. The excellent surface finish helps to prevent surface defects and ensures that the rolled products have a consistent and attractive appearance.



Application


Wire and Cable Industry

In the wire and cable industry, the High Speed Steel Roll Ring is used in the production of wires and cables of various sizes and types. It plays a crucial role in shaping and sizing the wire and cable materials, ensuring their proper formation and quality. The roll ring's high speed capability and precision enable the production of wires and cables with uniform diameters and smooth surfaces.

Machinery Manufacturing

For machinery manufacturing, the High Speed Steel Roll Ring is used in the production of various mechanical components, such as shafts, gears, and bearings. These components require high precision and quality, which can be achieved with the use of the roll ring. The roll ring's ability to withstand high loads and speeds makes it suitable for the manufacturing of heavy-duty machinery components.

Energy Sector

In the energy sector, the High Speed Steel Roll Ring is used in the production of components for power generation and transmission systems. For example, it is used in the rolling of steel bars for the construction of power plants and in the production of copper wires for electrical transmission. The roll ring's reliability and performance are essential in ensuring the efficient operation of these energy-related components.
