FERRO SILICON

Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

Q: Can hard alloy be welded with silver electrode?: Hard alloy can use silver electrode welding, some more liquid silver wire than general tin brass or iron brass, the cost is too high, the strength level than the ordinary copper electrode should be higher, personal suggestions for the selection of copper base up instead of silver electrode, such as the WEWELDING 46 electrode (referred to as Odin Wei 46 If the strength of electrodes), the structure is higher than silver, if it is to achieve the high permeability, it is still the ideal to silver, only from the strength level, is not WEWELDING 46 copper based electrode.

Q: Carbide yk20? What do you mean?: Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.

Q: What does carbide wet grinding mean?: 2. the number of grinding bodiesThe number of grinding bodies is usually described by the fill factor. The filling factor is equal to the ratio of the volume of the grinding ball to the volume of the cartridge.It is generally believed that the ball mill with carbide ball and carbide lining can guarantee the minimum coefficient of filling of rolling grinding by 0.4. When the filling coefficient exceeds 0.5, the ball near the center of rotation is blocked by the ball because of the small radius of rotation, so it is in a relatively static state with the grinding cylinder and reduces the grinding efficiency. Moreover, with the increase of filling factor, the grinding efficiency decreases regularly

Q: What cemented carbide does 2gr13 use?: 2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.

Q: Carbide and carbon steel: Carbon steel is a relatively traditional black metal material, according to the carbon content, nature, use, there are many categories. Carbon steels contain almost no alloying elements (except trace elements such as silicon, sulfur, phosphorus, etc.) during smelting. Carbon steel can be used for many daily purposes.Cemented carbide is a relatively new powder metallurgy material developed in recent years. The finish of the cemented carbide products is very high, even higher than that of ordinary quenched steel. Therefore, a machining tool that is often used as ferrous metal.

Q: Material properties of Cemented Carbides: Metal carbides, especially B, B, IV V VI B metal carbide melting point is above 3273K, the TAC hafnium carbide, respectively 4160K and 4150K, is the highest point currently know material. Most of the carbide hardness large, their microhardness is higher than 1800kg mm2 (micro hardness is hardness says one way for hard alloy and hard compound, microhardness 1800kg mm2 is equivalent to a diamond a Mohs hardness of 9). Many carbides are difficult to break down at high temperatures, and their antioxidant power is stronger than their constituent metals. Titanium carbide has the best thermal stability in all carbides, and is a very important metal type carbide. However, in an oxidizing atmosphere, all carbides are readily oxidized at high temperatures, which can be said to be a major weakness of carbides. In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids of the metal lattices and form interstitial solid solutions. They are similar to the gap carbide in that they can conduct electricity, heat conduction, high melting point, high hardness and great brittleness at the same time. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 DEG C.

Q: The welding welding hard alloy cutter, should use what type of flame why: With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be

Q: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!: Another case is that the chemicals in the polishing fluid react with the Co phase in the alloy, causing the Co to overflow or Co to deposit again, so that you need to consider whether you need to replace the polishing fluid.

Q: What about cemented carbide produced in Zhuzhou? What brand is good?: Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.

Q: What are the carbide inserts on the turning tool welded to the handle?: The common oxygen welding and brazing flux borax and welding line! The welding method is as follows: when welding, first use four carbon chloride (CCl4) to wash the welding section of the knife pole, and then use the oxygen and acetylene to turn the tool red and then sprinkle borax! Melt the copper into the top of the knife. Place the blade on the knife and continue to burn until the copper and alloy blades come in contact. An ordinary soldering knife comes out.
