LG15-H High-Speed ​​Hole Type

Designed for High-Speed Tube Rolling

High-speed grooved roll dies are engineered for demanding cold-rolled tube production lines where rolling speed, dimensional accuracy, and tooling durability are equally important. With a carefully engineered groove profile, these roll dies support stable metal deformation during continuous high-speed rolling.

The optimized die structure helps control material flow while maintaining the required inner and outer tube dimensions. It can also help reduce unnecessary material loss and improve overall production efficiency in large-volume tube manufacturing.

Optimized Groove Profile for Accurate Forming

The groove geometry plays an important role in controlling how metal moves during the cold rolling process. A precisely manufactured groove profile helps distribute the material more evenly and supports consistent tube forming.

By optimizing metal flow through each rolling pass, the dies are designed to improve dimensional control and reduce the risk of surface defects. This makes them suitable for applications requiring high-precision finished tubes.

Durable Construction for Demanding Production

These roll dies are manufactured from high-alloy steel, wear-resistant steel, or tool steel, depending on the required application. Professional surface treatments can further improve resistance to wear, fatigue, and repeated mechanical loading.

The tooling is designed to operate in demanding production environments involving high rolling speeds, elevated temperatures, and continuous workloads, helping maintain stable forming performance over extended production cycles.

Key Performance Features

High-Speed Rolling Capability

The dies are developed specifically for high-speed cold rolling applications, supporting efficient operation on modern tube production lines.

Precision Groove Design

The engineered groove profile helps optimize material distribution and maintain control over the finished tube's inner and outer diameters.

High Wear and Fatigue Resistance

Durable tooling materials combined with surface treatments such as chrome plating, nitriding, and hardening improve resistance to repeated rolling stress and surface wear.

Improved Production Efficiency

Precision manufacturing and high-speed pass design help increase rolling efficiency while reducing material waste during tube forming.

Stable Performance at Elevated Temperatures

The dies are designed for operating temperatures between 200°C and 350°C, supporting demanding continuous production conditions.

Internal Cooling

An internal cooling system helps manage operating temperatures during the rolling process and supports stable tooling performance.
