High-carbon ferrochrome smelting process

 High-carbon ferrochrome smelting blast furnace method, electric furnace, plasma furnace method. Blast obtained using only about 30% chromium cast iron was special. Currently, high-carbon ferrochrome chromium high flux method most used in the submerged arc furnace smelting.

     The basic principle of high carbon ferrochrome smelting furnace method is to use a carbon reduction of chromium ore of chromium and iron oxides Stainless steel springs. Carbon reduction of chromium oxide generated Cr2C2 start temperature of 1373K, the reaction initiation temperature generated Cr7C3 1403K, and the reducing reaction generating chromium start temperature of 1523K, and thus when the carbon reduction of chromium ore is obtained chromium carbide,stainless steel wire rod chromium metal instead of . Ferrochrome carbon content level depends on the reaction temperature. Generate high carbon content of carbide is easier than generating low carbon content of carbide.

Introduction of high-carbon ferrochrome basics

Chromium is a shiny gray metal, the density of 7.2, a melting point of 1857 ℃, boiling point 2672 ℃, malleable,Electro Polishing Quality Wire  but becomes rigid when the oxygen-containing, hydrogen, carbon and nitrogen and other impurities and brittle. Inert chemical nature of chromium, oxygen and water vapor at room temperature is stable, chromium and oxygen react begins at above 600 ℃, but after the surface oxide film, the reaction will be slow, when heated to 1200 ℃, the oxide film is destroyed, the reaction becomes faster again.Stainless Steel Shaped Wire At high temperature, chromium and nitrogen, carbon, sulfur reacts. Chromium and fluoride can effect at room temperature. Chromium can be dissolved in hydrochloric acid, sulfuric acid and perchloric acid, nitric acid passivation after the case, no reaction with the acid. Chromium with magnesium, titanium, tungsten, zirconium, vanadium, nickel, tantalum, yttrium alloy formation. Chromium and its alloys have strong corrosion resistance.

Carbon ferrochrome

    Alias: big eyes, also known as chromium-carbon ferrochrome

    Natural attributes: natural blocks, each weighing no more than 15 kg, size is less than 20 * 20mm weight ferrochrome blocks shall not exceed 5% of the total weight of ferrochrome.

    Grade: high chromium to 50% chromium content as baseline assessment unit

    Status: natural blocks, each weighing no more than 15 kg, size is less than 20 * 20mm weight ferrochrome blocks shall not exceed 5% of the total weight of ferrochrome.

    GB Standard: GB / T5683-1987

    Packing: According to the requirements, can be used in bulk, bags and drums.

    Origin: Jilin, Yingkou, Inner Mongolia, Shanxi, Sichuan

    Note: the material, size (ferrochrome chromium content of 50% as a baseline assessment of the unit).

    Application: Ferrochrome is the most important raw material for the production of stainless steel, mainly used in the production of 304 Stainless Steel Binding Wire, ball bearing steel, tool steel, nitriding steel, heat resistant steel, quenched and tempered steel, hardened steel and hydrogen-resistant steel, which is due chromium in stainless steel play a decisive role in determining the elements ofStainless Steel Fishing Wire   of only one genus, which is chrome, stainless steel are sure each contain a certain amount of chromium. The corrosion resistance of Annealing Steel Wire mainly from chromium. Experimental results show that only a chromium content of more than 12% when the corrosion resistance of steel will be greatly improved, so that the amount of chromium-containing stainless steel is generally not less than 12%. So supply and demand and the supply and demand situation chromite is closely related to the stainless steel market.High-carbon ferrochrome material: high carbon ferrochrome raw chrome ore, coke and silica. Chrome ore Cr2O3≥40%, Cr2O3 / ΣFeO≥2.5, S <0.05%, P <0.07%, MgO and Al2O3 content is not too high, size 10 ~ 70mm, the case of refractory ore, smaller size should be appropriate.Coke request containing fixed carbon is not less than 84%, ash content of less than 15%, S <0.6%, particle size of 3 ~ 20mm.Containing silica requires SiO2≥97%, Al2O3≤1.0%, thermal stability and good performance, without soil, size 20 ~ 80mm.

Determine the role of chromium in stainless steel

 Stainless steel elements of the decision is only one genus, which is chrome, stainless steel each contain a certain amount of chromium. To date, no chromium-free stainless steel. Chromium stainless steel performance have become key elements determine the fundamental reason is that after adding chrome Stainless Steel Cold Heading Wire as an alloying element, prompting its internal contradictions in favor of the motion to resist corrosion damage aspects of development. This change can be explained in the following areas:

     ① chromium electrode potential iron-based solid solution to improve Binding Binding Wire .

     ② electronic chromium iron absorption iron passivation
     Passivation is blocked due to the anode reaction caused by the corrosion resistance of metals and alloys can be improved on. Theory of metals and alloys constitute passive lot, mainly film theory, adsorption deals on electronic arrangement.

Stainless steel smelting raw materials

The main raw materials, scrap steel EAF have to return to the steel, ferroalloy, slagging materials, oxidizers, and carburizing agent.
1) scrap iron and steel: iron and steel scrap is the main metal electric steelmaking materials. Scrap iron and steel used in the electric furnace has the following requirements:1. Calls less rust, rust and moisture containing oxide, the heat decomposition process, increasing the oxygen content in steel. Another component of the liquid steel is not easy to control;2. scrap steel and oil should have sediment, sediment increases finished steel components of silica and aluminum oxide, oil, increase the hydrogen content in the steel;3. The clip should have a non-ferrous metal scrap steel. Non-ferrous metals will affect the mechanical properties of steel and reduce the life of the furnace.The high levels of non-metallic impurities should not, otherwise it will prolong the melting time and reduce the quality of finished steel.5. scrap iron levels can be suitable, excessive scrap refractory comparison, too small scrap charge is easily oxidized and extended time.
2) Return of steel:
    Weaving Wire Returns steel refers to steel-making plant because of component failure or other reasons, but I scrapped ingots and casting, underwrite, and rolling workshop cutting head, tail and rolling cut waste and so on.
3) Ferroalloys:
   Ferroalloy furnace used in relatively high demand:1. The high content of alloying elements, reduce heat consumption during melting. This high-alloy steel smelting time is very important.2. Fragmentation ferroalloy suitability, fragmentation of the General Assembly to extend the melting time too, the block is too small it is easy to float on top, increasing the burning loss, reduced recovery of alloying elements.
Annealing Steel Wire 
 3. The alloy should not contain slag and other non-metallic inclusions, the content of sulfur, phosphorus, and gas is lower.
4) slag material and oxidant:
    Alkaline furnace slag material used mainly lime, fluorite and clay blocks, etc.; oxidant iron ore, iron oxide and oxygen. For the slag material, requires the use of low-temperature dry before removing moisture.
5) recarburizer:
    Materials used in the smelting of liquid steel by carbon called carbon agent. Common electrode blocks coke and pig iron toner.

Magnetic stainless steel

People often assume that the adsorption of stainless steel magnet, and verify the authenticity of their advantages and disadvantages, do not smoke, non-magnetic, considered to be a good, genuine; suck those magnetic, is considered to be counterfeit fakes. In fact, this is an extremely one-sided, no practical method to identify errors. Many types of stainless steel screws, at room temperature, according to the organizational structure can be divided into several categories:
1. Austenitic type: If 304,321,316,310, etc;
2. Martensite or ferrite: as 430,420,410, etc.;
Austenitic type is non-magnetic or weakly magnetic, martensite or ferrite is magnetic.
Usually used as a decorative tube plate is austenitic stainless majority of 304, in general, is a non-magnetic or weakly magnetic, but the chemical composition fluctuations caused by smelting or processing may occur in different magnetic state, but can not be considered counterfeit or substandard, which is what causes it?
Austenitic mentioned above are non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to improper segregation smelting or heat, can cause a small amount of martensite in austenitic 304 stainless steel or ferrite body tissue. Thus, the 304 will carry the weak magnetism.
Further, 304 stainless steel wire after cold working to the martensite transformation structure also, the greater the degree of cold deformation, more martensite transformation, the greater the magnetic steel. Like steel batch numbers, production Φ76 tube, no significant magnetic induction, production Φ9.5 tube. Ling bending deformation due to the larger number of magnetic induction is obvious, because the production of rectangular tube pipe deformation than large, especially knuckle part, more intense magnetic distortion is more evident.
To completely eliminate the magnetic steel above 304 causes, can be opened to restore stability austenite at high temperature solution treatment, thereby erasing magnetic.
In particular, proposed that the magnetic 304 stainless steel caused due to the above reasons, and other materials of stainless steel, such as 430, magnetic steel is absolutely not the same level, ie Stainless Steel Spring Wire always shows weak magnetism.
This tells us that if the weak magnetic stainless steel or entirely without magnetic, should be determined as 304 or 316; if the magnetic steel of the same, showing a ferromagnetic, because discrimination is not 304.
