Blast furnace auxiliary facilities include: hot-blast stove, gravitation dust catcher, water granulated slag piling yard, main control room, gas cleaning system, blower station, de-dusting system for cast-house, coal powder injection system, mud milling room, switchgear station, material charging system

高炉辅助设施包括：热鼓风炉，重力除尘器，水渣设施，主控室，煤气净化设施，鼓风机站，出铁场除尘系统，煤份喷吹设施，碾泥机室，开关站，原料装料系统，冷却塔，浊环水泵站，沉定池，连铸机，铁块库，，铁水罐修理间，铁水称重系统。

In order to increase the hot metal throughput of main trough, some reforms to the trough were carried out, and in order to realize zero-interval tapping and meet the needs for smooth operation and intensified smelting of BF, the management and maintenance of taphole were strengthened at Maanshan Steel's 2500 m~3 BF.

马钢2500m~3高炉通过对渣铁沟进行技术改造，增加了主沟通铁量；通过加强铁口管理与维护，实现了零间隔出铁，满足了高炉强化冶炼的需要。

The blast furnace keeps the preferable and safe production state by strengthening equipment look-over and maintenance,adjusting operation system,improving coal gas flow distribution,stabilizing BF running,perfecting protection of BF with limonite in the burden,giving attention to management of casthouse and adopting beneficiated material etc.

通过强化炉体炉缸设备的点检和维护力度、调整操作制度、改善煤气流分布、稳定炉况顺行、完善钛矿护炉模式、加强出渣铁作业管理和精料等一系列措施，使得高炉保持在较好的和安全的生产状态。

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。
