What Is the Automation Route in Steel Manufacturing?
The automation route in steel manufacturing runs from model detailing to cutting, assembly, welding, straightening, blasting, and delivery control. Honglu Group anchors this route with more than 1,000 detailing engineers using Tekla Structures and annual steel-structure capacity exceeding 5 million tons. The plant route includes:
- BIM/detailing and QR-code model management
- CNC fiber laser cutting and marking
- H-beam assembly and flange straightening
- Robotic welding and submerged-arc welding
- Sa2.5 shot blasting per GB/T 8923
This makes steel processing automation a controlled production route rather than a single-machine upgrade.
Which Cutting Machines Start the Digital Steel Process?
The HLMSF26030-20000W intelligent CNC fiber laser cutting machine starts the digital steel process with 20,000 W laser power, Raycus MFMC-20000W source, 40 m fiber cable, 3D 5-axis Gangchun cutting head, Honglu self-developed LNC nesting/control software, and Mingtu MP380V profile-inspection sensor. Honglu plants also run BOND26030-30KW and JTLC26030-30KW machines, with about 700 laser units in the fleet. Plant machines reach up to 30 kW, cut plate up to 70 mm thick, and hold 0.5 mm precision through verified production data.
CNC fiber laser cutting machines connect marking, beveling, and inspection.
Which Welding Equipment Carries Structural Steel Throughput?
Structural steel throughput depends on coordinated robotic and automatic welding equipment. Honglu’s verified equipment base includes rail-guided robots, submerged-arc robots, gantry welders, and compact collaborative robots:
| Equipment | Model | Units |
|---|---|---|
| Rail-guided robot welding workstation | HLZZHJ-R-QJLX-12 | 2,000 |
| Submerged-arc welding workstation | HLZZHJ-R-QJLX-12M | 200 |
| Double-arc double-wire gantry welder | LMZ-1800-S | 200 |
| Compact collaborative welding robot | HLQQHJ-R-SR3C-705 | 800 |
This equipment stack supports automated welding systems across H-columns, box columns, crane beams, and irregular components.
How Does Honglu Control Surface Preparation and Material Input?
Honglu controls surface preparation and material input through centralized procurement, verified stockpiles, and pass-through shot blasting. All raw steel is centrally procured by the group with zero trader purchases, and year-round stockpile is at least 300,000 tons, including Q390, Q420, and Q460. All Q355B plates at least 20 mm comply with Grade III Ultrasonic Testing. The Q1525-10 pass-through shot blasting machine has 500 units and reaches Sa2.5 per GB/T 8923 for workpieces up to 1500 x 2500 mm. This keeps intelligent manufacturing steel tied to material discipline.
Which Certifications Prove the Manufacturing System?
Honglu’s manufacturing system is anchored by named certifications and steel-structure qualifications. The management systems are ISO 9001, ISO 14001, and ISO 45001. International fabrication anchors include AISC, EN 1090-1, EN 1090-2, ISO 3834, UKCA, GOST-R, CIDB, CPA, and IBS. China-side qualifications include Special Grade Steel Structure Manufacturing Qualification, Class B Light Steel Structure Design Qualification, Grade I General Contracting Qualification for Construction Projects, Green Product Certification, and National Green Factory status. These entities connect automation to audited steel manufacturing, not isolated manufacturing technology trends.
