• Alloy steel bars

• Special steel bars

Applicable steel grades include carbon steel, low-alloy steel, spring steel, bearing steel, and other special steels.

Working Principle of High-Speed Bar Production Line

The production line adopts a continuous rolling process. Heated billets are rolled through multiple stands, where the cross-section is gradually reduced while the rolling speed increases.

Key features of the rolling process include:

• No-twist or low-twist rolling technology, ensuring stable bar shape

• High-speed finishing block, enabling uniform microstructure

• Precise tension control, reducing dimensional deviation

• Controlled cooling system, improving mechanical properties

This advanced rolling method ensures high output with consistent quality.

Main Equipment of High-Speed Bar Production Line

A complete High-Speed Bar Production Line typically consists of:

1. Reheating Furnace

Uniformly heats steel billets to the optimal rolling temperature, ensuring good plasticity and stable rolling.

2. Roughing and Intermediate Rolling Mills

Reduce billet size step by step and prepare material for high-speed finishing rolling.

3. High-Speed Finishing Mill Block

Core equipment of the line, enabling high-speed rolling with excellent dimensional accuracy and surface finish.

4. Controlled Cooling System

Adjusts cooling rate to meet different mechanical property requirements.

5. Flying Shear

Cuts bars to fixed lengths accurately at high speed.

6. Cooling Bed

Allows bars to cool naturally while maintaining straightness.

7. Straightening Machine

Ensures final products meet straightness and dimensional standards.

8. Bundling and Packaging System

Automated collection, bundling, and labeling for efficient logistics.

9. Electrical and Automation System

PLC-based control system ensures stable operation, real-time monitoring, and fault diagnosis.
