LD-30 rolling mill rolls

Product Overview

Cold-rolled tube rolling dies are precision forming tools used in cold rolling production lines for manufacturing metal tubes with consistent dimensions and surface quality. Through optimized die design and precision machining, these rolling dies help maintain accurate tube geometry and stable forming performance throughout production.

They can be applied to tubes with different cross-sectional profiles, including round, square, rectangular, and oval shapes, making them suitable for various tube specifications and material requirements.

High-Strength Materials for Long-Term Forming

The rolling dies are manufactured from high-alloy steel or wear-resistant steel, providing the strength and durability required for continuous cold rolling operations.

With appropriate heat and surface treatments, the dies offer high compressive strength, wear resistance, and thermal stability. These characteristics help maintain forming accuracy during high-load and extended production cycles while reducing premature die wear.

Key Features

Precision Machining

Advanced machining processes help maintain dimensional accuracy during tube forming, supporting precise control of both inner and outer tube diameters as well as surface quality.

High Wear Resistance

High-strength alloy steel and wear-resistant steel provide a durable foundation for the dies. Additional surface treatments can further improve resistance to wear during repeated rolling operations.

Broad Application Compatibility

The dies can be customized for different tube specifications, materials, and cross-sectional profiles. They are suitable for round, square, rectangular, and other tube configurations.

Efficient Cold Rolling

An optimized roller structure helps improve material utilization and reduce unnecessary material loss during forming, contributing to more efficient production.

Stable Performance

Heat treatment and surface treatment processes improve the dies' resistance to demanding operating conditions, helping maintain consistent forming performance during long production runs.

Applications

Cold-rolled tube rolling dies can be used in the production of metal tubes and pipelines for a variety of industries, including:

• Oil and natural gas pipeline production

• Automotive tube manufacturing

• Aerospace components

• Power industry pipelines

• Chemical industry piping
