本发明的目的是通过如下途径实现的：一种低钛高碳铬铁生产工艺：
取铬铁：Cr2O3≥40％，Cr/Fe≥1.8，(MgO+CaO)Al2O3＝1-1.6，Ti≤0.1％，粒度40mm；
焦炭：固定炭≥82％，灰分≤15％，P≤0.025％，Ti≤0.15％，粒度6-18mm；
硅石：SiO2≥97％，Al2O3≤1.5％，水洗无杂质，粒度20-40mm；
将上述原料混合置炉中冶炼，炉内温度在1600-1800℃之间，在冶炼过程中控制炉渣三元渣型MgO32-38％，SiO228-32％，Al2O322-27％，在冶炼过程中及时补充炉料，尤其是在出铁口区域定期附加焦碳及镁质材料，冶炼出Ti≤0.03％的低钛高碳铬铁。
本发明含Ti≤0.03％，满足了对此类特性品种的要求，通过试用，用本发明作添加剂生产的特殊钢的耐磨性和强度均得到了满足是，市场前景看好，将使我国特殊钢材的质量取得大的突破。
具体实施方式
