【海绵铁简介】
海绵铁又称直接还原铁(即DRI)，是以优质赤铁矿石为原料，海绵铁采用优质矿石，利用氧化还原反应原理，通过滤式除淀方式进行排除，对管道、锅炉和循环水溶解氧腐蚀经水处理后水溶解氧含量可将到0.05mg/L以下。
在回转窑、竖炉或其他反应器内，用煤、焦炭，天然气或氢气，使铁矿石或铁精矿球团在低于物料熔化温度的条件下进行低温还原，变成多孔状的产物。其中被还原出来的铁呈细小铁核，形如海锦，故称海绵铁，经冷却、破碎、磁选，可除去脉石或其他杂质(金属铁占全铁90％以上者，可直接用于炼钢；90％以下的，用于高炉或电炉炼铁)。
【海绵铁特点】
1、使用寿命长、无毒、不污染环境，出水含氧量稳定在0.05mg/L以下，完全符合国家低压锅炉水质标准（GB1576-2001）要求。
2、常温运行，无需加热，运行成本低，克服了热力除氧，真空除氧须加热耗能的缺点。
用量少，一般情况下除氧剂消耗量1吨水为10g。
3、反洗频率低，再生效果好。
海绵铁滤料具有较好的还原活性和高比表面积特点，作为水除氧剂的海绵粒度为2-5mm，孔隙率极高，比表面积大，活性高，极易与水中的氧发生反应生成Fe3O3,从而达到除氧目的，反应产物为不易溶于水的絮状沉淀，被拦截下来，用一定强度的反洗水可以冲洗干净。
【海绵铁制成方法】
1、铁磷还原法：轧钢氧化铁磷是钢材在加热炉中加热后在轧制过程中，其表面氧化层自行脱落而产生的。还原海绵铁除氧剂可采用热轧沸腾钢氧化铁磷作原料，因为沸腾钢氧化铁磷中的TFe、C、S、P化学成分含量，能满足还原海绵铁生产的技术要求，在还原海绵铁中最好不要以高碳钢或合金钢氧化铁磷为原料。
2、铁精矿粉还原法：磁铁矿的主要成分是Fe3O4经采用湿式球磨、湿式磁选、联合选矿工艺后产出的普通精矿粉，是生产还原海绵铁的优选原料。
3、直接还原铁：通过精铁粉或氧化铁在炉内经低温还原形式的低碳多孔状物质，其化学成分稳定，杂质含量少，主要用作电炉炼钢的原料，也可作为转炉炼钢的冷却剂，如果经二次还原还可供粉末冶金用。

【 introduction of sponge iron 】
Sponge iron is also called the direct reduced iron (DRI), is a high-quality hematite stone as raw material, USES the high quality sponge iron ore, using the REDOX reaction principle, through a filter in addition to rule out in the form of lake pipe, boiler and circulating water dissolved oxygen corrosion after water treatment water dissolved oxygen content can be below 0.05 mg/L.
In rotary kiln, shaft furnace or other reactor, coal, coke, gas or hydrogen gas, iron ore and pellets of iron concentrate in below material melt temperature under the condition of low temperature reduction, become the product of cellular.The reduction of iron with small iron core, like brocade, therefore calls the sponge iron, after cooling, crushing, magnetic separation, can eliminate gangue or other impurities (metallic iron more than 90% of total iron, can be directly used in steelmaking; below 90%, used in the blast furnace or electric furnace ironmaking).
【 The characteristics of sponge iron 】
1, long service life, non-toxic, no pollution, stable discharging oxygen levels below 0.05 mg/L, completely conform to the state of low pressure boiler water quality standard (GB1576-2001).
2, normal temperature operation, without heating, low running cost, overcome the thermal deoxidization, vacuum deaerating heating energy consumption of faults.
Less dosage, usually deoxidizer 1 tons of water consumption for 10 g.
3, backwashing frequency is low, the effect is good.
Sponge iron filter material has good reduction activities, and the characteristics of the high specific surface area, as water deoxidizer sponge granularity for 2-5 mm, high porosity, specific surface area, high activity, easy to react with the oxygen in the water to generate Fe3O3, to reach deaerating purpose, flocks of reaction product is not easy to dissolve in water, be stopped, with a certain intensity backwashing water can rinse clean.
【 sponge iron method 】
1, iron, phosphorus reduction method: rolling iron oxide phosphor is heated in the heating furnace in steel rolling process, the surface oxide layer to fall off.Reduction sponge iron deoxidant hot rolled steel iron oxide phosphor can be used as raw material, because the rimming steel iron oxide phosphor of TFe, C, S and P content of chemical composition, can satisfy the requirements of the reduction of sponge iron production, the reduction of had better not in sponge iron with high carbon steel or alloy steel iron phosphate as raw material.
2 reduction method: iron ore concentrate, the main components of the magnetite is Fe3O4 by using wet ball mill, wet magnetic separation, the joint output after ordinary mineral beneficiation process, is the preferred material for the production reduction sponge iron.
3, the direct reduced iron: through fine iron powder or ferric oxide in the Canon of low temperature reduction furnace low carbon in the form of porous material, its chemical composition stability, less impurity content, mainly used as electric furnace steelmaking raw material, also can be used as a coolant of converter steelmaking, if through second reduction is also available for powder metallurgy.
【 sponge iron use 】
1, sponge iron is suitable for the hot water boiler of hydrate;
2, sponge iron is suitable for low pressure steam boiler feed water;
3, sponge iron is suitable for the industrial circulating cooling water filling water;
4, sponge iron is suitable for oilfield water injection.
