钢中氢含量的研究与实践

Research and Practice of Hydrogen Content in Steel

钢水中氢含量高会引起铸坯表面气孔缺陷,导致轧材裂纹,严重影响产品质量,本文通过研究季节、天气、温度、湿度对钢中氢含量的影响,对不同环境下真空炉定氢数据的统计,发现夏季氢含量较其余季节高。研究钢水季节性氢含量变化及合理的真空处理时间,对于降低氢致裂纹危害,提高产品质量具有重要意义。

High hydrogen content in Molten Steel will lead to porosity on the surface of billet,cause cracks in rolled products,and seriously affect the quality of products,it is found that the hydrogen content in summer is higher than that in other seasons.It is important to study the seasonal variation of hydrogen content in Molten Steel in order to reduce the harm of hydrogen-induced cracking and improve product quality.
