摘要
针对精炼与非精炼船钢低温冲击值的差异,分析了两种钢的化学成分、夹杂物和显微组织等对冲击值的影响。结果表明,钢的精炼可以增加钢的耐冲击能力,使钢的冲击韧性大大提高,满足实际使用要求。
For the difference of ship steel low temperature impact value, the effects of chemical composition, inclusion and microstructure of the refined and unrefined steel are analyzed. The results show that the refinement of steel can increase the impact resistance of steel, so the impact toughness was increased considerably to meet the reqirement of practical usage.
