我国钢铁产品标准中较普遍地存在三个方面的不当规定:1.表面质量列出了一些肉眼不能分辨的缺陷名称;2.缺乏针对性的低倍和高倍检验项目;3.增加一些错误或无效的检验项目。此外,和其他冲击试验采用ISO摆锤的国家一样,存在对于船板等低碳钢冲击吸收功规定值太低而造成使用安全隐患的危险,这些问题不解决,不仅在全国范围内造成很大浪费,而且,会显示我国有关标准技术水平落后面貌,与我们这个世界钢铁大国地位不相称。因为这些问题涉及面广纠正难,本文希望引起有关专家和用户的讨论和争鸣,以便统一认识,尽快纠正错误。
There are three aspects of the Chinese iron and steel product standards are generally more than the inappropriate provisions: 1. Surface quality lists some of the naked eye can not distinguish the name of the defect; 2. Lack of targeted low and high magnification test items; 3. Add some errors or Invalid test item. In addition, as in other countries where ISO pendulum impact tests are used, there is a danger that the value of the impact absorption function of low-carbon steel such as ship plates will be too low, which may cause potential safety hazard for use. These problems are not solved and not only result in a large national scale Waste, and will show that the backwardness of our country’s standard technological level is not commensurate with the position of our world’s steel powerhouse. Because these issues involve a wide range of corrections, this article hopes to arouse discussion and debate among relevant experts and users in order to unify their understanding and rectify mistakes as soon as possible.
