锻件表面清理处理工艺｜Surface Cleaning of Forgings: Shot Blast, Sand Blast, Grinding
Over-blasting moves dimensions and over-grinding creates stress raisers. How much cleaning is actually enough?
继续阅读锻件无损探伤工艺实操｜Non-Destructive Testing of Forgings in Practice
Magnetic particle finds surface cracks, ultrasonic finds internal ones. What has to be true before either test means anything?
继续阅读锻件力学性能稳定管控工艺｜Holding Mechanical Properties Stable in Forged Parts
Tensile, yield and impact results that scatter across batches usually come from heat number, forging reduction or heat treatment. Which one do you check first?
继续阅读常见锻件裂纹、折叠缺陷原因分析｜Cracks and Laps in Forgings: Tracing the Cause
A lap is never a finishing problem. Trace cracks and laps back through cooling, forming, heating and cutting — which step actually caused it?
继续阅读锻件冷却及后续热处理工艺｜Post-Forging Cooling and Heat Treatment
Alloy steel left to cool in a draught will crack. What cooling schedule does each material need, and what does normalising actually fix?
继续阅读热锻热切边工艺与毛刺控制｜Hot Trimming: Temperature, Clearance and Burr Control
Trim too hot and the part deforms; too cold and the flash tears instead of shearing. Where is the window, and what clearance does it need?
继续阅读锻坯去氧化皮工艺方案对比｜Descaling Billets: High-Pressure Water versus Mechanical
Scale pressed into the die becomes a surface defect and a wear problem. Water jet or brush — and why does descaling sometimes achieve nothing?
继续阅读锻造模具选材、润滑与维护工艺｜Forging Dies: Material, Lubrication and Maintenance
Die life is decided as much by preheating and lubrication as by the steel grade. What kills a hot forging die, and how do you slow it down?
继续阅读精密锻造成型工艺实操要点｜Impression Die Forging: Preform, Finish and What Controls Fill
Most laps and short fills are decided in the preform, not the finishing impression. What has to be right before the last blow?
继续阅读坯料感应加热工艺与温度管控｜Induction Heating of Billets: Soak, Overheat and Temperature Control
A billet that is red on the outside and cold in the core will not fill the die. How do you guarantee through-heating without overheating the surface?
