质检总局公布第三批轴承钢抽查结果合格率为100%
发布日期：2024-02-07
轴承网记者从国家质检总局公布的第3批轴承钢材产品质量国家监督抽查结果当中了解到，本次监督检验共抽查了46家企业的46批产品，企业数量约为获得生产许可证企业数量的三成，可以有效反映目前轴承钢材产品的总体质量状况。检测结果出来表明，46家企业的46批产品全部达到标准，抽查企业合格率和产品合格率均为100%，成绩优秀。
记者从本次抽查背后了解到，本次抽查重点是对轴承钢材的化学成分、显微孔隙、显微组织、碳化物带状、碳化物网状、低倍检验和非金属夹杂物等的含量指标进行检测。我们从检测结果得知：化学成分检验、产品退火硬度检验都符合要求，显微孔隙、显微组织、碳化物带状、碳化物网状、碳化物液析、低倍检验和非金属夹杂物检验均合格。但是从检验数据分析可以看出，个别企业由于生产产品程度的水平普遍不高，生产控制能力也并不理想，产品质量稳定性仍有待提高；此次抽查还反映出部分国有大型企业生产的轴承钢材非金属夹杂物级别较高，这就佐证了他们在轴承钢冶炼控制方面不够严格。
轴承钢是用于制造滚动轴承的滚珠，滚柱和套筒等的钢种，也特别用于制作精密量具，机床丝杠等。近些年，我国轴承行业快速发展，中国已经成为世界最大的轴承生产国之一。国内使用轴承的行业主要集中在汽车、摩托车、家用电器、铁路轴承、农用机械、冶金矿山机械、石油化工机械以及纺织机械等。 轴承的发展正随着工业社会进步的发展而发展，质量越来越成为当代行业以及客户的第一诉求，只有产品合格了，才能真正的得到客户的信赖。
