FeSi is used as a source of silicon to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel; ferromanganese, spiegeleisen, silicides of calcium, and many other materials are used for the same purpose. It can be used to make other ferroalloys. Ferrosilicon is also used for manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electromotors and transformer cores. In the manufacture of cast iron, ferrosilicon is used for inoculation of the iron to accelerate graphitization.

High Class Of FeSi As Deoxidizer

Q: Does the hard alloy belong to the composite material?: 1. carbide is based on tungsten carbide as matrix, cobalt as binder, according to the needs of the titanium, tantalum, niobium and other metals to obtain the "alloy" material.2. because this alloy is relatively hard, so called him "carbide", people often used to do machining tools.3., from the definition of "composite material", "alloy" belongs to "composite material"". Therefore, cemented carbide belongs to composite material.

Q: What kind of carbide alloy is used in stainless steel processing?: The hardness of stainless steel is martensite, high hardness, using tungsten cobalt (do not use tungsten cobalt titanium, this is the 1 note) and Ta containing hard alloy.

Q: What are the features of cemented carbide YG8 knives?: Density: 14.6-14.8; hardness HRA:90.5; flexural strength, Mpa2300High bending strength, shock resistance and vibration resistance is better than YG6. It is suitable for low speed rough machining of cast iron, non-ferrous metals and their alloys, and non-metallic materials

Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?: The wear resistance of cemented carbide is related to the proportion of titanium carbide and cobalt carbide contained in it. It contains more titanium carbide, less cobalt content, higher hardness and better wear resistance. But brittleness also increases, easy to break the edge, so it is suitable for finishing.

Q: What kind of grinding wheel is the most suitable for carbide tools?. My existing grinder, 2800 rpm, /s wheel diameter, can hold 250mm. Please help answer.: Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon steel. 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 kind of industry can use carbide?: Blade material used in mechanical processing

Q: What alloy tool can be used as hard alloy?: Wire cutting can be cut open. As for what knife car?... I said, man, you have a technical problem

Q: How are cemented carbides separated from the cutting tools?: Brazing heating to melt after the pain, you can take off!

Q: Customers ask whether cemented carbide can be used in the food industry! ~: Used for processing food should not be possible, the composition of tungsten carbide.

Q: What does "YC20.1 carbide" brand mean?: PriceFor example, the ordinary 20 party 90 degrees welding tool used A320 blade, the price of 11 yuan, non tax written price /20120716 Edition
