摘要

介绍了含硼微合金钢的成分，显示了硼对钢结晶过程、提高强度和韧性的积极作用。使用硼浓度较低的含硼铁合金的可行性已得到证实。指出了使用复杂的含硼合金来中和氮和氧的必要性。举例说明了一种以硅铁和锰铁为基础的复合合金，其中含有硼添加剂，是用达托石精矿获得的。

Increasing the efficiency of microalloying steel with boron‑containing alloys

Compositions for microalloying steel with boron are presented, its positive effect on the process of steel crystallization, increasing strength and toughness is shown. The feasibility of using boron‑containing ferroalloys with low boron concentrations is substantiated. The need to use complex boron‑containing alloys to neutralize nitrogen and oxygen is noted. An example of a complex alloy based on ferrosilicon and ferromanganese with boron additives, obtained using datolite concentrate, is given.
