Where the lowest price of sponge iron

Tel: [010-58538872] Mobile: [13,718,228,976] it is important that we see from the above information in our country efforts in the development of science of our country, sponge iron filter believe the government believe water resources, of course, water quality sponge iron filter will change in this regard in the field of application of the ability to show with everyone together to usher in drinking water. Sponge iron sponge iron (sponge iron) Description: high quality sponge iron ore, the use of oxidation-reduction reaction principle, except through the filter precipitate manner exclusion, after pipes, boilers and circulating water dissolved oxygen corrosion by dissolved oxygen content in water treatment can be will to 0.05mg / L or less. In the rotary kiln, furnace or other reactors, coal, coke, natural gas or hydrogen, iron ore or iron ore pellets at a temperature below the melting temperature of the material conditions of low temperature and converted into porous product . Which is reduced to iron out was small iron core, shaped like a sea Jin, he said. Sponge iron by cooling, crushing, magnetic separation, can be removed gangue or other impurities (metallic iron accounted for more than 90% iron, could be directly used in steelmaking; 90% less for blast furnace or electric furnace ironmaking). Under lower than the melting temperature of the reduction of iron ore into sponge iron production process, its products direct reduced iron (ie DRI), also known as sponge iron. The product has not been melted, remains ore shape, reducing loss of oxygen due to the formation of large pores, sponges in the shape of the Mission under the microscope named. Sponge iron is characterized by low (<1%) carbon content, and save the ore gangue. These features make it inappropriate for large-scale steelmaking, only suitable as a substitute scrap electric steelmaking raw materials. Sponge iron sulfur, phosphorus and other harmful impurities and non-ferrous metal content is low, is conducive to high-quality steel smelting furnace. More than 97% iron content also belong to sponge iron, but used in powder metallurgy field, and its sub-block and powder form (a reduced iron powder), such as deep-processing can be done twice reduced iron powder, iron content will more than 99%. Normal block sponge iron filter (also known as oxygen scavenger) using high-quality ore, the use of oxidation-reduction reaction principle, except through the filter precipitate manner exclusion of pipes, boilers, water is recycled water dissolved oxygen content in the treated corroded up to 0.05 mg / L or less, and having a backwash frequency is low, high compressive strength, not powder, not structural plate, large surface area, long life, high activity and good regeneration effect, etc; full compliance with state water quality standards for boilers . Iron content of more than 97 percent of sponge iron, used in powder metallurgy field, and its sub-block and powder form (a reduced iron powder), such as deep-processing can be done twice reduced iron powder, iron content will reach 99% above, the price is correspondingly higher; sponge (sponge filter) is lower porous ferrite fine iron ores in the furnace is formed by low temperature reduction, its chemical composition and stability, low sulfur, phosphorus and other impurity elements, use it to replace scrap as a special steel smelting, steel excellent senior charge on the iron and steel industry. Restore can be used by the second powder metallurgy, the price is relatively cheap. In recent years sponge iron was developed for boiler water circulation oxygen oxygen instead of steel scrap in previous years, because of the oxygen effect, low investment, low cost of tons of water treatment, maintenance is increasingly simple application; sponge iron has a strong reduction activity and specific surface characteristics of water as an oxygen scavenger sponge size is 2-5mm, high porosity, large surface area, high activity, prone to reaction with oxygen in water to generate Fe3o3 , so as to achieve the purpose of oxygen, the reaction product is readily soluble in water flocculent precipitate, was blocked off, with a certain intensity of backwash water can rinse. Sponge iron consumption is very low, depending on the quantity and quality of treatment, usually 3--6 months supplement once; softened water because not easy to make the surface passivation oxygen scavenger to slow down the oxidation, The influence of oxygen effect, it should be softened and then oxygen. After a period of time, should be backwashed
