Raw Material Coils
Raw materials coils are mainly from cold forged steel produced by several high-quality domestic steel enterprises like Shanghai Baosteel, Xingtai Iron and Steel, Maanshan Iron and Steel, Xiangtan Iron and Steel and others. All the raw materials are recorded when they enter the factory and inspection is carried out. Tracing through the system, we can obtain the production furnace number for the wire coils and their process flow before entering the factory, realizing the integration of information technology into all processes. Our quality staff first checks and records the following aspects: size, weight, appearance, chemical composition, metallography, decarburization layer, factory labels and raw material certificate.
Phosphoric Acid Pickling
Eagle Metalware Co., Ltd. possesses a full complement of advanced automated processing equipment for material restructuring with a monthly processing capacity of over 8,000 tons. Key technologies from raw material spheroidizing, pickling, phosphating and saponification to the suction line can be independently controlled. Eagle Metalware Co., Ltd. strictly manages the raw materials by batch, and systematically manages and tracks the key factors of people, machines and materials that affect product quality from the procurement and receiving of raw materials and restructuring to fine line storage to ensure that the quality of every link during the process can be instantly controlled and tracked.
The factory of Eagle Metalware Co., Ltd. in Kunshan has introduced a fully-automatic foreign pickling line, which can automatically detect the chemical composition within the pickling line and adjust the acidity according to the current status to ensure that the wire is processed in a stable technical process. 360-degree water cannons inside the line can ensure a smooth surface and fewer material defects and improve the corrosion resistance of surface coatings after being painted, thus upgrading the pickling line and improving the quality of the phosphoric acid pickling processing.
Eagle Metalware Co., Ltd. uses an advanced Japanese STC spheroidizing annealing furnace and the most advanced spheroidizing annealing technology to automatically conduct reforming heat treatment on the cold forged steel and special steel. The whole system can be specially controlled and monitored, and the good-quality furnace structure and automatic gas control can avoid decarburization well. After the spheroidization, the crystal structure nodularity of the alloy steel wire is excellent, the hardness is well-distributed, the quality is stable, and the normal temperature workability is excellent. Eagle Metalware Co., Ltd., referring to the standards in JB/T5074-2007 Low and Medium Carbon Steel Spheroid Body Rating, decides on the metallographic structure and identifies those above level 5 as qualified. Fully automatic control and regular quality checks by personnel ensure the quality.
Drawn Steel Wire
Eagle Metalware Co., Ltd. has introduced the most advanced precision suction line equipment from Taiwan, and the professional team from the wire coil department utilizes a standardized process. They can remold wire rods with multiple techniques, including rough suction, precise suction, double spheroidizing and suction, triple spheroidizing and suction, etc. After pickling, raw material can be cold processed with different molds, and be drawn into wire rods in various sizes, ranging fromΦ 0.8 mm to Φ 42.0 mm. The engineering department will confirm the suction process according to the requirements of the order, and make sure to use superior quality lube oil. During the stretching process, the tension of the dual frequency variable speed motor is stable, and the metal flow is in good condition without folding when the wires are reformed, and crystalline structure is fine and homogeneous. This fully guarantees the high quality in restructuring the wire.
