采用电炉碳热法成功地生产了含Si≥63％,Ba≥6％的硅钡铁合金,合金成分稳定。含Si72.27％、Ba2.26％的硅钡铁合金在弹簧钢60Si2Mn钢种中试用,钢的铸态组织、主要的力学性能与使用硅铁合金相比有明显改善和提高;含Si65.35％,Ba7.24％的硅钡铁合金与以硅铁、硅钙作铸铁孕育剂对比,孕育效果较好,孕育抗衰能力也较高,改善了铸件的切屑加工性能和减少了铸件的缩孔倾向。
The electric furnace carbothermal method has been successfully produced with Si ≥ 63%, Ba ≥ 6% of barium iron alloy, alloy composition and stability. Si72.27%, Ba2.26% of silicon barium ferroalloy in spring steel 60Si2Mn steel trial, the cast steel structure, the main mechanical properties compared with the use of ferrosilicon significantly improved and improved; with Si65.35% , Ba7.24% of the barium iron alloy with ferrosilicon, calcium and calcium as inoculant contrast, better inoculation, pregnancy anti-failure is also higher, improving the chip processing performance and reduce the casting shrinkage tendency .
