Reduction iron powder principle and application? Today Tongling Fukang mining limited liability company will bring you the generation speed of the principle and application of iron sulfide reduction factors, in addition to let you know before the Tongling pyrite, can have more understanding of the industry!
The factors influence the generation rate of pyrite crusher reduction principle and application of iron sulfide
Must have a lot of friends do not understand the principle and application of reduced iron powder, iron sulfide today our manufacturers would like everyone to enjoy the wind, I hope everyone can look carefully, what deficiencies are welcome to visit our website and contact us oh iron sulfide manufacturers!
Principle and application of reduced iron powder
The commonly used equations for reducing iron powder in a chemistry course in secondary schools are (the first edition of the PEP book < < metals and compounds > >):
4H2O 3Fe (g) = high fever 4H2 =Fe3O4
Reduction of iron reducing agent is popular with solid or gas (coke, charcoal, anthracite, coal gas, natural gas, water into the decomposition of ammonia and hydrogen) reduction of iron oxide (iron ore, steel rolling iron scale etc.) to produce sponge iron. The reduction process is divided into (solid carbon reduction) a reduction and two reduction, a reduction is solid carbon reduction preparation of sponge iron, a reduction of the main process is: (iron concentrate, rolling iron scale etc.), separation, drying, crushing, sieving, canning, into a reduction furnace, sponge iron. Two times the reduction process: sponge iron - clean brush broken magnetic separation two reduction furnace powder block to crushing magnetic separation screening grading mixing packaging packaging products. With the production of high quality iron powder reduction method, the parameters of standard, Fe = 98%, C = 0.01%, phosphorus and total sulfur is less than 0.03%, hydrogen loss is 0.1 ~ 0.2%. The main purposes are: reduction of iron powder reduced iron powder metallurgy products, the industry consumption reduction of iron total 60%~80%. Adding 10 ~ 70% iron powder to the electrode can improve the welding process of the electrode and improve the deposition efficiency significantly. Chemical reduction iron, mainly used in chemical catalyst, precious metal reduction, alloy addition, copper replacement, etc.. Cutting stainless steel iron, in cutting steel products, iron powder injection to the oxygen acetylene flame, can improve the cutting performance, expand the scope of cutting steel, improve the cutting thickness. Powder metallurgy technology of our country continues to improve, the powder metallurgy parts are widely used in aircraft, firearms, motorcycles, cars, family cars, agricultural machinery, mining, electric tools, machine tools and application of the principle of reduction, reduction of iron transport and other machinery industry.
Many people see: [graphic] use of iron sulfide FES fire protection measures
Engaged in related industries must be generated to FES some understanding of the Anhui FES Xiaobian to understand their own to do a summary to share with you the generation speed of its factors which influence today:
From the formation mechanism of iron sulfide, in the daily production, the electrochemical corrosion reaction of ferrous sulfide is generated in iron sulfide under the action of the activity. Therefore, control of electrochemical corrosion is the key means to limit the formation of ferrous sulfide. As long as we find the production device prone to sulfur corrosion areas, take effective measures according to the characteristics of the parts, it can reduce the amount of iron sulfide, thus fundamentally avoid the self ignition accident. The sulfur content, temperature, water and the existence of Cl- are important factors affecting the rate of electrochemical corrosion reaction.
The above is the generation speed of Fukang Xiaobian summary "of its factors which influence", Xiao Bian said is not comprehensive enough, if you have a different view of the friends are welcome to call our hotline, to learn each other, Tongling mining Fukang is committed to providing customers provide the best quality products, product quality assurance reasonable price, is your best choice.
Read the "generation speed reduction principle and application effect of iron sulfide factors, we believe that the principle and application of reduced iron powder and other issues probably understand, if you want to know the iron sulfide manufacturers, manufacturers, wholesale, sales and other related content, please pay attention to the follow-up of our news!
