【昌盛】直销 除氧剂海绵铁

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

海绵铁除氧原理：

海绵铁滤料，常温过滤式除氧化学除氧，采用优质矿粉(活性海绵铁)，海绵铁主要成分是铁，其疏松多孔的内部结构，提供的比表面积是普通铁屑的5-10倍，可使水中的氧与铁发生迅速彻底的氧化反应，通过滤式除淀方式进行排除，对管道、锅炉很循环水溶解氧腐蚀经处理后水溶解氧含量可达到0.05 mg/L以下。

Brief introduction of sponge iron:

Sponge iron using high-quality ore, using redox reaction principle, through the filter type in addition to the way out, on the pipes, boilers and circulating water corrosion of dissolved oxygen of the water after treatment can be dissolved oxygen content below 0.05mg/L. In the rotary kiln, furnace or other reactor, coke, coal, natural gas or hydrogen, make the iron ore and iron ore pellet below the melting temperature of the material under the condition of low temperature reduction, into porous products. Among them were reduced iron with small iron core, shape such as Kam, it said. Sponge iron is cooling, crushing, magnetic separation, removing gangue or other impurities ( metallic iron total iron of 90% or more, can be directly used for steelmaking; 90% the following, for blast furnace or electric furnace ironmaking ).

Below the melting temperature under the iron ore is reduced to sponge iron in iron making process, its products for the direct reduction of iron (DRI ), also called sponge iron. The product without melting, remained ore shape, due to reduction of loss of oxygen to form a hole under the microscope observation mission, resembling a sponge. Sponge iron is characterized by low carbon content ( < 1% ), and preservation of the ore gangue. These characteristics make it unsuitable for large-scale converter steelmaking, is only suitable for scrap as raw material instead of electric furnace steelmaking. Sponge iron sulfur, phosphorus and other harmful impurities and non-ferrous metal content is low, to high-quality steel smelting electric furnace. The iron content of more than 97% also belong to the sponge iron, but used in the powder metallurgy field, in the shape of a block and powder ( a reduced iron powder ), such as deep processing can also be used as a two reduction of iron, the iron content above 99%.

Sponge iron filtering applicable scope:

1, suitable for hot water boiler make-up water;

2, suitable for low pressure steam boiler water supply;

3, applies to the industrial circulating cooling water;

In 4, applied to the oil field water injection

Sponge iron deoxygenation principle:

Sponge iron filter, normal temperature filtering deaerator Chemical Deoxygenation, using high-quality powder ( active sponge iron ), sponge iron is the main component of iron, the porous internal structure, the specific surface area is 5-10 times the ordinary iron, can make the water of oxygen and iron occurs rapidly complete oxidation reaction, through the filter type except the way out for pipeline, boiler, a circulating water corrosion of dissolved oxygen of the treated water dissolved oxygen content can reach 0.05 under mg/L.
