Frequently Asked Questions
The line is specifically engineered for strip steel materials Q195 to Q345, with a thickness range of 2.0mm to 5.0mm.
The flying saw allows for continuous production without stopping the forming line, achieving up to 15 cuts per minute with ±3mm accuracy.
The straightening machine features an active lower roller for movement, while the upper roller is pressed down via a manual worm gear for precise tension adjustment.
The cage looper acts as a material buffer, storing raw strip steel to ensure the forming and sizing machines operate continuously without interruption.
We use GCr15 bearing steel (HRC60-65) and 40Cr quenched and tempered steel for all critical rollers and shafts to prevent premature wear.
This specific configuration is optimized for diameters between φ76mm and φ89mm. Custom configurations are available for other size ranges.
