针对湘钢合金圆钢产品硬度偏高的问题,对比国内其他钢厂同类产品分析了钢材合金元素质量分数、分布及显微组织的异同及其对产品硬度的影响。分析认为湘钢产品硬度异常的原因是轧后冷却速度过快。这为改善湘钢合金圆钢棒材产品质量、降低硬度提供了理论依据。
The hardness of alloyed steel 42CrMo produced by Xiangtan Steel is higher than the standard. To ascertain the reason a comparison of the content, distribution of alloy element and steel microstructure for the same products in different domestic plants are made. The results showed that the abnormality of hardnees of the product is caused by over-high of cooling speed after rolling. The results provide the basis for improving the product quality.
