海绵铁简介:

　　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)。

　　在低于熔化温度之下将铁矿石还原成海绵铁的炼铁生产过程，其产品为直接还原铁（即DRI），也称海绵铁。该产品未经熔化，仍保持矿石外形，由于还原失氧形成大量气孔，在显微镜下观察团形似海绵而得名。海绵铁的特点是含碳低（＜1％），并保存了矿石中的脉石。这些特性使其不宜大规模用于转炉炼钢，只适于代替废钢作为电炉炼钢的原料。海绵铁中硫、磷等有害杂质与有色金属含量低，有利于电炉冶炼优质钢种。含铁量超过97％以上也属于海绵铁，但应用于粉末冶金领域，其形状分块状和粉状（一次还原铁粉），如深加工还可做二次还原铁粉，其含铁量将达到99％以上。

　　海绵铁理化指标:

　　产品特点:

　　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。

　　3.用量少，一般情况下除氧剂消耗量1吨水为10g。4.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。

　　海绵铁滤料适用范围:

　　1、适用于热水锅炉的补水;

　　2、适用于低压蒸汽锅炉的给水;

　　3、适用于工业循环冷却水补水;

　　4、适用于油田注水

　　海绵铁工作条件:

　　1.可在常温下除氧无需加热

　　2.可随时供水无需除氧水箱无需准备时间

　　3.除氧效果稳定可靠出水符合低压锅水质标准

　　4.安装方便无需高位安装

　　Sponge ironintroduction:

　　USES the high quality sponge iron ore, using REDOX reaction principle, through the filter type in addition to lake way out, pipe, boiler and circulating water dissolved oxygen corrosion by water treatment after water dissolved oxygen content can be to 0.05 mg/L the following. In the rotary kiln, vertical furnace or other reactor in coal, coke, natural gas, or hydrogen, iron or iron ore concentrate pellets in less than material melt temperature under the condition of low temperature reduction, e the product of cellular. The reduction of iron out a small iron nuclear, shape such as sea jin, it is called. Sponge iron after cooling, crushing, ic separation, can remove gangue or other impurities (metal iron ounted for 90% of all iron above, can be directly used in steelmaking, less than 90%, used for blast furnace or electric furnace ironmaking).

　　In the lower than that needed to melt temperature under the iron ore reduction ChengHaiMian iron ironmaking production process, and its products for direct reduced iron (DRI namely), also called sponge iron. This product without melting, still keep ore appearance, due to the reduction of oxygen form lots of hole under the microscope, so named like sponge. Sponge iron is characteristic of carbon low (< 1%), and saved the gangue minerals. These characteristics make it should not be used for large-scale converter steelmaking, only comfortable instead of scrap as electric furnace steelmaking raw materials. The sponge iron sulphur, phosphorus and other harmful impurity and nonferrous metal content is low, be helpful for electric furnace smelting quality grade of steel. Iron content more than 97% also belong to sponge iron, but used in powder metallurgy field, its shape points block and powder (a reduced iron powder), such as processing can also do secondary reduced iron powder, and its iron content will reach more than 99%.

　　Sponge iron physical and chemical indicators:

　　Name index name index

　　Active iron was 98% density 2.2 g/cm3

　　Compressive strength of 1500 n/T specific surface area of 85 g/cm3

　　Anticorrosion index acuities were 3.4 + 5.5 AL2O3 SiO2 or less

　　S 0.03% Cu or less 0.002% or less

　　Sn 0.002% Bi acuities 0.002% or less

　　Product features:

　　1. Long service life, non-toxic, polluting the environment, water stable oxygen in 0.05 mg/L the following, meets the national low pressure boiler water quality standard (GB1576-2001) requirements. 2. Room temperature operation, without heating, operation cost is low, to e the thermal deaeration, vacuum oxygen must be heating energy consumption ings. 3. Usage, usually oxygen agent consumption 1 ton water for 10 g. 4. Backwashing frequency is low, the regeneration effect is good.

　　Sponge iron filter material has good reduction activity and high surface area characteristics, as water oxygen agent sponge size is 2-5 mm, high porosity, specific surface area, high activity, it is easy and the water of oxygen generation Fe3O3 reaction, thus reach deaerating purpose, the reaction product is not easily soluble in water flocks, blocked down, with a certain intensity of backwashing water is rinsed clean.

　　Sponge iron filter material suitable for:

　　1, suitable for hot water boiler water;

　　2, suitable for low pressure steam boiler feed water;

　　3, suitable for industrial circulating cooling water filling water;

　　4, suitable for oil field water injection

　　Sponge iron working conditions:

　　1. Can be in normal temperature oxygen without heating

　　2. Water may at any time without oxygen tank without preparation time

　　3. Deaerating effect is stable and reliable water with low pressure pot water quality standards

　　4. Easy installation without high installation
