Ferro Silicon



Ferrosilicon is produced by reduction of silica or sand with coke in presence of scrap iron, millscale, or other source of iron.

Ferrosilicons with silicon content up to about 15% are made in blast furnaces lined with acid fire bricks. Ferrosilicons with higher silicon content are made in electric arc furnaces.

An overabundance of silica is used to prevent formation of silicon carbide. Microsilica is a useful byproduct.

The melting point and density of ferrosilicon depends on its silicon content.

Q:What are the YT and YG carbide cutting tools for each occasion and why is it necessary to improve the quality of the machined surface?
YT for steel, steel castings, aluminum parts, not shock resistance. YG is used for rough cast iron parts, cast iron parts, shock resistance and high temperature resistance.
Q:Carbide coated drill bit will reduce the service life after grinding, how to avoid?
Sure, the grinding efficiency of the drill can reach about 80% of the new drill. Of course, the repair should be professional, experienced manufacturers repair oh. We can drill hard alloy coated drill bit to ensure quality.
Q:Buy whole cold carbide drills
We are an internal cold carbide drill production professional manufacturers, imported materials, five axis processing.
Q:What kinds of carbides are there? How should we choose in production?
Basically divided into four major categories: YG, YW, YS, YT.YG is cast iron, nonferrous metal, base alloy steel.YW is made of stainless steel and base alloy steel.YS is the finishing of high strength steel, steel and cast steel.YT is the rough processing of steel and cast steel.
Q:The use of cemented carbides YG and YT
Two, titanium is a rare metal, characterized by light weight, high strength and good corrosion resistance. Because of its stable chemical properties, good resistance to high temperature, low temperature, strong acid, alkali resistance, as well as high strength and low density, has been praised as "space metal"". YT alloy and YW alloy have better properties than YG because they contain titanium.
Q:What type of carbide for punching dies? Better. Where can I buy it?
Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
Q:What about cemented carbide produced in Zhuzhou? What brand is good?
Diamond brand still has a certain position, the 1 floor said that the fine carbide sales company, I pass there every day, but also put Alibaba lights in there
Q:Several hard alloy cutter lathe with?
YG car, pig iron and so on, YT, steel and the like, high temperature resistant, YW car alloy steel, the highest strength.
Q:What kinds of carbide knives do you have? Write out its main functions and uses.
The commonly used cemented carbides are mainly based on WC, and are classified into the following categories whether or not they are added to other carbides:(1) tungsten cobalt (WC+Co) cemented carbide (YG);It consists of WC and Co, has high flexural strength toughness, good thermal conductivity, but poor heat resistance and wear resistance, mainly for the processing of cast iron and non-ferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, its hardness wear resistance than YG3, YG6 high strength and toughness is poor, suitable for machining hard cast iron, austenitic stainless steel, heat-resistant alloy, hard bronze.
Q:Can CBN wheels grind cemented carbide? Why?
Tungsten carbide and non-metallic ceramic materials are usually made of diamond grinding wheels.CBN can iron group elements of workpiece.According to the development trend of ordinary abrasive abrasive, > superhard abrasiveCorundum like A - >CBN BSilicon carbide C> diamond DThe rule: A sends to B, C develops D
