轴承网记者日前获悉，河北钢铁集团石钢公司通过技术攻关，采用精细化冶炼手段，成功冶炼出供某跨国公司制作大规格曲轴的钢材，进一步提升了石钢产品的行业竞争力和品牌影响力。
曲轴是发动机不可或缺的主要旋转机件。曲轴在工作中受到不断变化的燃气压力、惯性力及力矩作用,从而在各部分产生弯曲、扭转、剪切、拉压等交变应力。曲轴的重要性及其工作状况的复杂性,要求曲轴用钢必须同时具备较高的抗拉强度、疲劳强度、表面强度、耐磨性,同时还要有一定的韧性。由于客户所产曲轴用于出口海外市场，以前多采用进口材料。该钢种的质量要求很高。不仅对各种微量元素的要求非常严格，还对DI值有特殊要求，对钢材偏析要求也非常高，生产难度很大。
为确保该钢种的开发成功，石钢公司技术部门加大了工作实践力度，认真落实科技研发蓝图，并且进行了多番生产方案的论证，优选了最稳妥的技术控制方案。炼钢厂组织生产骨干，针对技术要求和控制要点，有的放矢组织生产，通过精细、合理安排精炼周期，分阶段取样等措施，提取了大量生产数据，并通过科学的精炼模型进行生产指导，有效解决了合金成分偏析等生产难题。同时，为降低生产成本，炼钢厂多方举措，大力提高连浇炉次，最大限度利用中包寿命，在最经济的生产前提下，成功生产出该牌号钢种，并通过了客户的试用审核。
曲轴钢材的成功开发，代表着一种新钢材的问世，也同时意味着石钢又增加一款替代进口材料的优秀钢种，不仅可以提高石钢公司通过科学有效的操作手法去保证钢材产品质量稳定性，还也提升了石钢产品的影响力和竞争力，使石钢产品在产品这块立于不败之地。
