摘要
对硬线钢盘条在拉拔过程中出现的脆断问题进行了分析,通过优化连铸工艺,铸坯的中心碳偏析、缩孔等缺陷明显得到改善,提高了硬线盘条钢质量。
Brittle fracture of hard wire bar in drawing is analyzed. By optimizing casting process, the defects of central carbon segregation and shrinkage cavity in casting billet got obviously corrected, the quality of steel also improved.
