Product Name: 90% F. C Carbon Additive/Calcined Anthracite Coal Additives / Low Price Type: Industrial Circulating Water Treatment Agent Appearance: Granulars Color: Black Environmental Protection: Yes Acid-base Property: Alkaline Surface Disposal Agent Specific Gravity: 0.9t/M3 Fixed Carbon: 70-95% Bulk Density: 0.85g/cm3 Ash: 6% Vm.: 7% Moisture: 3% Sample: Free Transport Package: 25kg/Bag or 1tonbag Specification: 0.5-6mm Origin: China Product Description 90% F.C Carbon Additive/Calcined Anthracite Coal Additives / Low PriceIntroduction of the anthracite filter:Anthracite filter material with high quality anthracite as raw material, through the selection, crushing, and two screening, high mechanical strength, good compression performance, chemical stability, no toxic substances, wear resistance, in acid, neutral, alkaline water are not dissolved, and anthracite particle surface roughness, good adsorption capacity, high porosity, with light, low required back washing strength, can save a lot of water and electricity.Commonly size:0.5-1, 1-2, 2-4, 4-6, 6-8mm 0.5-0.8, 0.8-1.2, 0.8-1.8mmFeatures of the anthracite filter:High mechanical strength.Chemical stability.Strong interception capacity.Large water treatment.Long service cycle.Usage of the anthracite filter:Anthracite filter material with quartz sand filter material with the use of the current promotion of double rapid filter and three layer filter, filter tank filter is the best material to increase the filter speed increase the unit area of water and increase the sewage interception capacity, reduce the project cost and reduce the area of the most effective way. Anthracite filter material is now widely used in chemical industry, metallurgy, thermal power, pharmaceutical, paper, printing and dyeing, food and so on before and after the production of water treatment process.Specification of the anthracite filter:Fixed carbon80-90%V.M.6-7%Moisture3%Bulk density0.85g/cm3Volume-weight0.94Ash6%Hardness3-4Hydrochloric acid dissolution rate3.5%Introduction of the calcined anthracite coal:Coal carbonizing agent made of high quality anthracite as raw material, is in 1300 centigrade high temperature carbonization reduce volatile, used to enhance the fixed carbon content and density, strength, oxidation resistance and products. It has high fixed carbon content, strong oxidation resistance, low content of harmful elements. As reducing agent in smelting process. Recarburizer is to complement the carbon content in liquid steel required for increasing carbon containing material. Electric arc furnace steelmaking process, can add coke or anthracite as carburetant in charging. Due to its high ash content and volatile matter content, induction furnace melting cast iron is rarely used as a carburizing agent.Specification of the anthracite carburant:Commonly size1-5mmFixed carbon80-95%S(low)0.6%S(High)3%Moisture0.5%Ash0.6%V.M0.5%Usage of the carburant:For casting, cast iron, cast steel, casting will have a requirement of carbon, then carburizing agent, as the name implies, is to increase the carbon content of molten iron, for example, in charge used in smelting pig iron, scrap steel, scrap, pig iron carbon content is high, but the purchase price of scrap is higher section of, so the increase in scrap amount invested, pig iron reduces the amount invested, and carburizing agent, can play a role in reducing the cost of castings.
