The invention discloses a synthetic using method of smelting high-furnace dust, which comprises the following steps: grinding the high-furnace dust with 1.5-15% zinc; proceeding magnetic cobbing; reclassifying to obtain the refined ferric ore; disposing ore tail through waste acid of titanium dioxide with 15-30% sulphuric acid; transmitting the zinc oxide in the solution at zinc sulfate pattern; separating solid and liquid solution through lime; obtaining refined zinc ore through S2-, CO32-, HCO3- ion; floating the immersed slag through neutral oil.

一种炼铁高炉炉尘资源综合利用的方法，含锌1.5％～15％的高炉炉尘经磨矿、磁选、重选回收铁矿物获得铁精矿，选矿尾矿用含硫酸15％～30％的钛白废酸处理，使其中的氧化锌以硫酸锌的形式转入溶液中，固液分离得出的溶液用石灰中和除铁后，再用S2-、CO32-、HCO3-离子沉锌获得锌精矿，浸出渣用中性油浮选获得炭精矿。该方法将钛白废酸和高炉炉尘结合在一起，使之成为互为所需的原料和试剂，有效地将两种废弃物变成了有价资源，较好解决了环境污染问题，同时又能产生好的经济效益。

By optimizing such process as refining dreg series and deoxidizing,mode of adding slagging raw materials,blowing Ar system,preventing nitrogen adding in refining process,adopting such process measures as controlling degree of superheat of smelten steel strictly,selecting suitable pulling speed and colling water quantity,using electromagnetism stir in continuous casting,the center carbon segregation index is at about 1.04 basic...

通过对精炼工序中精炼渣系和脱氧工艺选择、造渣原料的加入方式、吹氩制度、防止增氮等工艺的优化，在连铸中采用严格控制钢水过热度、选用合适的拉速和冷却水量、使用电磁搅拌等工艺措施，中心碳偏析指数集中在1.04左右，夹杂物尺寸变小、数量大为减少，疏松和缩孔均降低到0.5级以下，线材面缩率达到34%以上，大部分为41%~44%，索氏体体积分数达到91%，可顺利拉拔至0.3 mm。

The deficiency in the some localities of the big plane of the interior-lid and the difference in composite effect in columned surface are the main reasons leading to interior-lid invalid.
