Dealing with Orange-peel and Residual Hammer Marks
表面橘皮与锤痕残留的处理

若出现细密"橘皮"或锤痕压不平，多半是退火不足导致金属过硬、或走锤无序使高点被反复推到别处。对策：重新整体退火至深樱桃红后缓冷，再用更平滑的锤面、严格螺旋走锤重打。已产生硬化层时可先 600 目砂纸轻磨再打，切忌加大蛮力硬砸。
Fine "orange-peel" or unplanished marks usually mean insufficient annealing (metal too hard) or random striking that merely pushes high spots around. Remedy: re-anneal the whole piece to a deep cherry red and cool slowly, then rework with a smoother face and strict spiral sequence. If a work-hardened layer exists, lightly sand at 600 grit first—never force it with heavier blows. ---
