Product Description:

Ferro Silicon alloy

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

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

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

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

Usage

1. Ferro silicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys.This prevents the loss of carbon from the molten steel (so called blocking the heat);

2. Ferro silicon 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. In arc welding, ferrosilicon can be found in some electrode coatings.

3.Ferro silicon is a basis for manufacture of prealloys like magnesium ferrosilicon (MgFeSi), used for modification of melted malleable iron. Ferrosilicon is also important as an additive to cast irons for controlling the initial content of silicon.

4.Ferro silicon is also used in the Pidgeon process to make magnesium from dolomite.

Q:How to distinguish cemented carbide grades?
(3) titanium cobalt tungsten tantalum carbide (WC+TiC+TaC+Co)) (YW YS) "the main processing of heat resistant steel, high manganese steel, stainless steel and other hard materials processing" in addition to TaC YT hard alloy on (NbC), improve the bending strength, impact toughness, high hardness, wear-resistant and anti oxygen ability. Can be processed and can be made of steel, cast iron and non-ferrous metals. It is often called the universal hard alloy (also known as the universal hard alloy). The following is a variety of grades, density, bending strength, hardness and flexural strength hardness grade use density of use of YG3X 14.6-15.2 132092 is suitable for cast iron, nonferrous metals and alloy steel small alloy steel cutting section of high-speed machining. K01 YG3X YG6A 14.6-15.0 137091.5 for hard cast iron, non-ferrous metalsalloys, also suitable for high manganese steel, hardened steel, alloy steel and semi finishing K05 YG6A YG6X 14.6-15.0 finishing. 142091 it is proved that the alloy processing of chilled alloy cast iron and alloy steel can obtain good results, finishing is suitable for ordinary iron. K10 YG6X YK15 14.2-14.6 210091 for the whole processing of drilling, milling, reaming and alloy cutter. Have high wear resistance and toughness of K15. K20 YK15 YG6 14.5-14.9 138089 is suitable for cast iron, nonferrous metals and alloy non metallic materials at medium cutting speed precision. K20 YG6 YG6X-1 14.6-15.0 150090 is suitable for cast iron, nonferrous metals and alloy non metal material during continuous cutting finishing, discontinuous cutting the semi refined car, fine car, small car, coarse fine car section thread, continuous section semi finishing milling and finish milling, rough and fine hole expansion. K20 YG6X-1 YG8N 14.5-14.8 200090 is suitable for cast iron, cast iron, ductile iron and chromium, High speed machining of nickel stainless steel alloy.
Q:Hard alloy die polishing with what can be reached Ukraine black brightness
What if this need to die, the smaller diameter must be black if the large diameter is bright, with a diamond grinding paste and polishing powder
Q:Is carbide resistant to alkali?
Hard alloy chemical composition are general acid-base stability, it has no effect on, also has strong alkali resistant corrosion resistant hard alloy sintered hard alloy is added in different metal powders, can improve the hard alloy for corrosion resistance
Q:What are the fields of nano WC Cemented Carbides applied?
(3) wood processing. As early as 50s, carbide tipped tools were used in the wood processing industry. Now, there sheet of all kinds of materials, the processing precision and the requirements of the appearance is greatly improved, the centrifugal force, when high speed cutting cutting force so that ordinary hard alloy is difficult to meet the requirements of the processing, and nanocrystalline WC cemented carbide has been useless.
Q:Carbide drills and high-speed steel drills, which are suitable for processing stainless steel 10?
If it's cylindrical carbide, it's better to be on the drill bit or as a guide
Q:What kind of etching solution should be used for metallographic observation of MIG and TIG welding of cobalt based carbide and medium low carbon steel? Ten
According to the usage, the cobalt based alloy can be divided into cobalt base alloy wear, high temperature resistant cobalt and cobalt base alloy abrasion and corrosion of the alloy in aqueous solution. The general condition is both wear resistant or wear resistant and corrosion resistant performance, some conditions may also require high temperature wear resistance and corrosion resistance, and more in this complex condition, the more it can reflect the advantage of cobalt base alloy.
Q:What is the hardness of the carbide thread?
The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.
Q:Carbide drills and cobalt high speed steel bit, which is good? What's the difference between these two materials?
This is the first use, each one has its own merits, hard alloy with high hardness, suitable for high speed drilling and high hardness materials, and high cobalt high speed steel has good toughness, suitable for low hardness material, suitable for drilling slower machine.
Q:What blade does the high carbide material use?
CBN diamond tools, the price is relatively high, high hardness with this basic file, but not the car more than 55 degrees of hardening, if necessary diamond tools contact me. Domestic imports.
Q:How are cemented carbides separated from the cutting tools?
Brazing heating to melt after the pain, you can take off!
