1）添加Ti、Nb、V和Zr，并与C含量保持平衡，减少毛刺；2）钢中形成MnS单体或MnS类型夹杂物，以改善切削加工性；3）将硬性的夹杂物来覆盖柔性的夹杂物；4）调整热轧工艺和SiO2、MnO的比率。
The combustibility, thermal stability and mechanics performance of flame-retardant viscose fibers modified by blending modification were evaluated by Limit Oxygen Index（LOI）, X-ray diffraction（XRD）, Thermogravimetry（TG） analysis, Differentiate thermogravimetry （DTG） analysis and Scanning electron microscope（SEM）. The results indicated that LOI of the flame retardant viscose fiber was 27.5 % ,crystallinity and mechanics performance were reduced and the thermal stability of the modified fiber was improved. The mechanism of the flame retardance was agglomerate block.
