Shanxi Jianing Forging regularly stocks 20#, A105, 45#, and other standard carbon and high-quality carbon steel raw materials. The station has complete real-world cases of carbon steel flanges, shafts, and ring forgings. Carbon steel forgings offer high cost performance and are suitable for manufacturing general industrial equipment.
In the manufacturing process of metallurgical equipment, carbon steel forgings are key components, and their quality directly affects the operational stability and service life of the equipment. When upgrading its production line, a metallurgical equipment factory in Taiyuan, Shanxi, set higher requirements for the strength, dimensional accuracy, and delivery time of carbon steel forgings. Drawing on years of industry experience, Jianing Forging provided this customer with customized carbon steel forging solutions, helping them achieve efficient production and cost control.
The original forging suppliers at this equipment factory had the following issues: First, internal defects such as looseness and inclusions in the internal structure of the forgings led to a high rate of post-processing defects and increased rework costs; Second, dimensional tolerance control is unstable, requiring secondary adjustments during assembly, which affects installation efficiency; Third, the supply cycle exceeds 45 days, making it impossible to match customers' fast-paced production schedules and limiting capacity release.
To address these pain points, Jianing Forging offers systematic solutions from three aspects: raw material control, process optimization, and delivery management. First, high-quality continuous casting round billets are selected as raw materials, refined grains through multi-pass forging ratio design, combined with normalizing + tempering heat treatment processes, resulting in a uniform and dense internal structure and stable mechanical properties of the forging. Second, CNC grinding ring equipment and fine molds were introduced to control the outer cylindrical tolerance of carbon steel forgings with diameters ranging from 200mm~1500mm to within ±0.5mm, with end face parallelism ≤0.3mm, achieving machine-free assembly. Finally, a dedicated tracking mechanism has been established from order to shipment, reducing the standard delivery cycle to 25 days and urgent orders to 18 days. At the same time, a full batch inspection report and material certification are provided, facilitating quality traceability.
