Detailed Product Description: | Serves Shanghai sponge iron prices Shun Sichuan Environmental Protection Technology Co., Ltd. science and technology as the forerunner, the quality of talent as a driving force, and adhere to the good after-sales service, quality and credibility to open up new markets. Rely on state-of-the-art production technology, the flexible mode of operation, superior products, quality of service, providing customers with high quality, high standards of water treatment products, we are willing to work together with you hand in hand to create a blue sky. Company a 24-hour service hotline :010 -56420693, 13810067470. The company's main Web site address: http://www.schb010.com/ the sponge iron active ingredient and the use of sponge iron characteristics of the active ingredient is mainly due to its unique processing technology: Sponge iron raw material in the rotary kiln, shaft furnace or other reactor inner, coal, coke, natural gas, or hydrogen gas, so that the iron ore or iron ore concentrates pellets under conditions below the material melting temperature of the low temperature reduction, into the porous product. Be restored iron was a small iron core, shaped as sea Kam, it said. After cooling, the sponge iron crushing, magnetic separation, remove the gangue or other impurities (metallic iron in total Fe more than 90%, can be directly used in steelmaking; 90% for the blast furnace or electric furnace ironmaking). Below the melting temperature is lower than the reduction of iron ore into sponge iron iron production process, its products direct reduced iron (DRI), also known as sponge iron. Without melting, the product remains the ore shape to restore the loss of oxygen to the formation of a large number of pores, named after the shape of sponge Observer Mission under a microscope. The characteristics of the sponge iron is low (<1%) of carbon, and saved in the ore gangue. These characteristics make it the only suitable place of scrap as a raw material for electric steelmaking should not be massive for converter steelmaking. Sponge iron, sulfur, phosphorus and other harmful impurities and non-ferrous metal content is low, and is conducive to high-quality steels smelting furnace. Iron content of more than 97% belonging to the sponge iron, but applied to the field of powder metallurgy, the shape of the sub-block (once reduced iron powder and powdered), such as deep-processing can also do the second reduced iron powder, iron content more than 99%. This is the predecessor of sponge iron filter material - the origin of sponge iron. Sponge iron filter material is the use of redox reaction principle-pass filter in addition to the lake way exclude dissolved oxygen corrosion of pipes, boilers and water circulation. Sponge iron oxygen scavenger of the treated water dissolved oxygen content can be reduced to less than 0.03mg / L, significantly lower than the national regulations of the use of water standards. Sponge iron filter media (oxygen scavenger) using high-quality ore redox reaction principle, the exclusion of the sponge iron oxygen scavenger sponge iron filter through filtering in addition to the lake the way, for pipes, boiler tower circulating water dissolved oxygen corrosion treated the oxygen content of the water depth solution can be to 0.05mg / l, the oxygen scavenger backwash low frequency, high compressive strength, not powder, not end plate, large surface area. Sponge iron oxygen scavenger sponge iron filter active regeneration effect, sponge iron filter media is completely in line with the national the boilers water quality standards. Oxygen content The sponge iron the filter (deoxidants) made of high quality ore using redox reaction principle, pass filter in addition to the lake the way the exclusion of the pipeline, boiler tower circulating water dissolved oxygen the corrosion treated water depth solution may be to 0.05mg / l or less, the oxygen scavenger backwash low frequency, high compressive strength, not powder, not structural plate, large surface area. High activity, good regeneration effect, in full compliance with the National Board of Boiler water quality standards. The activation treatment of the sponge iron deoxidants to the spongelike multi-void iron tablets, for dissolved oxygen in the water provided the opportunity of reacting with the reactive iron, accelerate the oxidation-reduction reaction. Iron sponge filter (oxygen scavenger) having good reduction activity and high surface area characteristics, the sponge iron the filter sponge iron deoxidants as water Deoxidant sponge granularity of 2-5mm and a high porosity, specific surface area high activity, easy to react with the oxygen in the water to generate Fe3O3, sponge iron the filter sponge iron oxygen scavenger to achieve deaerator purposes, the reaction product the flocculent precipitate readily soluble in water, was intercepted with a certain intensity sponge iron filter backwash water can rinse hardness 5 - 7 uneven coefficient k80 ≤ 1.8 Porosity 30-50% ash amount. |
