products information

Our factory supply 75% 72% 65% 45% four grades of ferrosilicon.

Ferrosilicon has been widely applied.in the steel industry, foundry industry and other industrial production.

Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.

High ferrosilicon or silicon alloys is used for the production of low-carbon reductant in ferroalloy industry. Adding ferrosilicon to cast iron can be inoculant for ductile iron, and can prevent the formation of carbides, and promote the precipitation of graphite and the nodulizing, so as to improve performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry,and coatings for welding electrodes in the electrode manufacturing.

In the steel industry, one ton of steel consumes about 3 ~ 5kg75% ferrosilicon.

Melting point: 75FeSi to 1300 ℃

Q: Hard alloy is tungsten?: You can understand that.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Cemented carbides include:Tungsten cobalt carbideThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).

Q: What are the main items of cemented carbide production process and finished products inspection, as well as the price of testing equipment, equipment and equipment?!! Please experts advice and answer, the younger brother will be grateful!!!!!!: From the simplest to the complex,Density test: Milito balance is good or bad, the equipment price is not the same, 3000 or soDetermination of coercive force: coercive magnetometerSpecific magnetic saturation intensity: magnetic saturation intensity testerHardness: Rockwell hardness testerBending strength: bending strength testerLook at the metallographic structure: Zeiss metallographic microscope

Q: The existing 60*60 standard cast iron plate, above 3 hard alloy welding specifications, probably in the 30*30, in which the appropriate welding method, know the friends willing to enlighten ah, thanks in advance.Some friends have said the binder is a copper brazing, the basic can be settled. As far as I know, many methods such as welding, high frequency welding, oxygen welding, I want to find a kind of welding method. The key is to understand the trouble with us, surface and surface welding: Welding hard alloy is the most used for brazing, welding of copper wire.

Q: Explain from the materialGeneral modelIf you buy itWhat parameters are provided?: Tungsten is on the hard alloy with tungsten carbide as the main (academic called tungsten based alloys), we called the daily hard alloy is usually tungsten based alloys, namely tungsten steel.There is another type of cemented carbide called titanium based cemented carbide, commonly known as "cermet"Buy it to shape (such as rods, blade), size and material (on behalf of the main chemical composition and particle size, but apart from a small number of national standard grade, most of them are the enterprise's own brand), and if you need special requirements (such as with cooling hole two 30 degrees within the spiral angle).

Q: Carbide cutting insert: Brand in general can be found above, but you can also go to Zhuzhou tungsten tungsten alloy to see, they have good quality there

Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?: The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.

Q: Carbide coated drill bit. Do you have one there?: 1. carbide drills are generally worn in the back. Then it has little influence on service life.2., the high strength of the workpiece material, easy to cause the front of the drill (spiral groove) wear, bit life impact.

Q: How to solve the severe wear of the flank of the carbide blade during machining?: 2. Contact the company or log on to the company's website for communication.Carbide inserts are made of hard alloy, an alloy made from refractory metals, hard compounds, and bonded metals by powder metallurgy.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

Q: What type of carbide is the most ductile?: Cemented carbide material with tungsten and cobalt carbide toughness is better, at present the carbide grade in the most toughness of YG15. The relation between cobalt content and toughness is shown below. It can be seen that cobalt content and 13%-16% toughness are the best. In this interval, only YG15 cobalt content is 15%.

Q: How are cemented carbides sintered?: Raw materials according to the provisions of the proportion of added alcohol or other medium in the wet ball mill in wet grinding, making them fully mixing, crushing, drying, sieving after adding wax or gel forming agent of a class, and then drying and sieving to prepare a mixture. Then, when the mixture is granulated and pressed and heated to a point near the bonding metal (1300~1500 DEG C), the eutectic alloy is formed by the hardening and bonding of the metal.
