Technical Specifications

Key Components of the Production Line

Auxiliary Machine Composition

The production line includes a single-station manual uncoiler, which accommodates steel strip coils with an inner diameter of Ф762mm and an outer diameter of Ф1800mm. The uncoiler is equipped with a belt width of 280mm and can handle weights up to 5 tons. For cutting and welding, the system features hydraulic cutting and pneumatic pressing platforms, along with manual welding (excluding the welding machine). A four-roller delivery machine ensures continuous feeding of raw materials, with a feeding speed of 140m/min.

The cage looper stores raw materials for the forming and sizing machine, allowing uninterrupted production. Its integral frame design includes adjustable support and tension rollers to accommodate varying steel strip widths. The computer flying saw machine ensures precise cutting, with a maximum sawing speed of 80m/min and a blade size of Ф900mm.

Main Machine Composition

The main machine features a passive seven-roller leveling system and a forming section with 7 flat and 8 vertical rollers. The sizing section includes 6 flat and 6 vertical rollers, while the extrusion and cooling systems ensure structural integrity. The horizontal shaft has a diameter of Ф100mm, and the vertical roller shaft is Ф60mm, both made from 40Cr steel and heat-treated for durability.

The extrusion roller shaft is Ф70mm in diameter, also constructed from 40Cr steel. The gear box uses ZG35# material with spiral bevel gears (module m=12) and 20CrMnTi alloy for enhanced load capacity. The DC motor (Z4-280-42, 250KW) and reducer (ZLY280-10) ensure robust performance.

Applications and Industry Relevance

This production line is widely used in line pipe steel manufacturing for applications such as gas pipelines, water supply systems, and structural support frameworks. The high-frequency welding process ensures high strength and minimal deformation, making it suitable for demanding environments. The system's high-speed forming (60–80m/min) and precise cutting capabilities cater to industries requiring consistent quality and efficiency.

According to the National Institute of Standards and Technology (NIST), "Manufacturing processes must adhere to strict dimensional and mechanical standards to ensure reliability and safety in critical applications" (https://www.nist.gov/). BzZhou Xinghua's production line aligns with these principles, offering a solution that meets global manufacturing benchmarks.
