<div class="over_x"><P>日前，在首钢专家及通化钢铁相关部门的指导下，通钢集团通化钢铁一炼钢厂开发试生产40Mn2B新钢种一次性获得成功，经检验该钢种化学成分一次命中率实现100%，铸坯表面质量良好。</P>
<P>40Mn2B系合金钢，用于生产汽车半轴，由于在开发过程中对其氮含量、氧含量、氢含量及其夹杂物的要求较为严格，所以在开发过程中存在一定的难度。为确保该钢种实现一次性成功开发，该厂会同首钢专家及技术中心相关部门，科学合理地制定钢种的技术要点及操作规程，并对技术要点及操作规程进行反复论证。同时，从生产原料、设备调试及人员保证等方面入手，积极做好产前的各项准备工作。目前，他们正在结合试生产各项工艺指标，认真做好开发生产的总结工作，为该钢种实现批量生产奠定了坚实基础。</P></div>
