Abstract
ER50-6 hot-rolled wire rod was fractured when drawing from φ5. 5 mm to φ2. 2 mm, there were much cracks near the fracture position. The reason of drawing fracture was analyzed by means of metallographic examination and micro-area analysis by scanning electron microscopy. The results showed that local carburetion had caused by slag entrapment defect of continuous casting billet, and the pearlite was obvious higher than matrix, the plasticity and toughness were reduced. At last it was fractured alone the carburetion area in the process of drawing.关键词
