火车提速引发的铁合金结构优化的思考

A Consideration of Ferroalloy Structure Optimization Arising from Train speeded-up

火车提速后，对钢材质量提出了更高的要求，从而引发了铁合金的质量和品种问题。只有依靠铁合金生产结构和品种结构优化才能适应火车提速后对钢材质量的新要求。

Higher quality steels have been required since train speeded-up, resulting in some problems such as the quality and type of ferroalloys. Only by optimizing the productive structure and varitety of ferroalloys, the new requirement to steels used for train speeded-up can be met.
