Description

Ferro Silicon is a kind of ferroalloy which is composed of ferrum and silicon. Ferro Silicon uses coke, quartz (or silica) as raw materials and is made by electric furnace. Because silicon and oxygen are easily compound into SiO2, the ferrosilicon is often used as deoxidizer in steelmaking.

Application

1. Ferrosilicon is often used as deoxidizer in steel- making.  

2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.

3. It can be used as a reductant in ferroalloy production and chemical industry.

4. In iron industry it can be used as inoculant and nodulizer.

Q:What are the standard units of measurement for carbide inserts?
Manufacturers usually use KG, which is used inside the shop
Q:Which hardness is 5 of carbon steel and alloy steel?
Uncertain.Carbon content is different, and some trace elements contain different categories.Alloy steel, which means hardening can harden even when cooled in air, and very sharp. It is a complex alloy steel, containing tungsten, molybdenum, chromium, vanadium and other carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60.Carbon steel, also called carbon steel, mainly refers to the mechanical properties of carbon depending on the content of steel, and generally do not add a large number of alloy elements of steel, sometimes referred to as general carbon steel or carbon steel. Of iron carbon alloys containing carbon less than 2% WC. Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.
Q:What is the reason for the metallographic cavity (as shown in the drawing) of cemented carbide?
YT14 Feiyan containing titanium, titanium with high oxygen affinity, if high oxygen content and sintering process not reasonable, high temperature gas production could not be drained to form holes, you see the sintering process is reasonable, the presence of liquid phase before the vacuum degree is not high enough. In addition, such as incomplete degassing holes in the product, the edge is more.
Q:What is the hardness of cemented carbide?
Different grades, different hardness, usually (86 ~ 93HRA, equivalent to 69 ~ 81HRC);
Q:Which prawns know of what is called red hard alloy.
This form of exercise is intense, and the more objects or systems formed by these microscopic particles become hotter. As the temperature rises, the object begins to emit visible light, first of all, the longer red part, which turns from dark red to orange red.
Q:I would like to solder a carbide tool now, what materials do you need to ask for specific methods?
You need to use the Ya alloy electrode and welding tool first articles to be heated to red (a temperature of about 800~1000 degrees) and then stained with borax flux (in the electrode when need to add) and then work hard alloy or welded tungsten steel tools a turning tool on the lathe tool holder can be cut off in the car turning bracket that is the
Q:What's the difference between high speed tool steel and carbide cutter?
For Aluminum Alloy in general, very low hardness, ordinary tool steel can be effectively processed. But more wear-resistant hard alloy, the size change in process tool is very small, which resulted in NC machining, all using carbide tools.On the other hand, the tendency of cemented carbide to adhere to aluminum material is lower than that of tool steel, which can effectively improve the surface finishBut hard alloy is more brittle, attention should be paid during use
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
Cobalt based alloy is a cemented carbide that is capable of various types of wear and corrosion as well as high temperature oxidation. Commonly known as the cobalt chromium tungsten (molybdenum) alloy or Si Taili (Stellite) alloy (Si Taili alloy invented by the American Elwood Hayness in 1907).
Q:Is the hard alloy the same as the cemented carbide?
Dissimilarity!Cemented carbide refers to one or more refractory metal carbides (WC, TiC, etc.) as hard phases, and transition metals (Co, etc.) as bonding phases and multiphase materials prepared by powder metallurgy technology. As carbide tools for cutting tools, the commonly used carbides are WC, TiC, TaC, NbC and so on. The commonly used bonding phases are Co, Ni, Fe and so on. The strength of cemented carbide depends mainly on the content of the binder phase.The ultra-fine Grain Cemented Carbide Kennametal company launched a new brand KC5525, KC5510 uses the high cobalt hard alloy matrix grain refinement, cemented carbide substrate with super grain refinement cobalt content up to 10%, with TiAlNPVD coating with high aluminum content, the tools in intermittent cutting with high edge toughness at the same time, also has a very strong deformation resistance. ISCAR company for solid carbide end mills "AL-TEC" brand series of coating, with ultra-fine Grain Cemented Carbide with high aluminum content, TiAlN (PVD) coating, which in milling high hardness of 60 ~ 62HRC hardened steel, compared with the original IC903 grade, improve tool life 150%. Valenite company for cast iron in high-speed turning VP1595 grades, but also in the ultra-fine grain cemented carbide substrate, using MT-CVD coated with 18 m thick TiCN/Al2O3/TiC coating, the flank is coated with a layer of gray TiC, in order to facilitate and blade rotation observing the wear of cutting edge, the grade in rough machining ductile iron, the processing efficiency than other K05 ~ K10 grade increased by 50%.
Q:What type and hardness of grinding wheel 20 for general carbide turning tools?
Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60Another grinder usually holds two pieces. A piece of green silicon carbide, a piece of brown corundum, brown corundum grinding wheel is used for iron, such as the size and hardness of the cutter bar and green silicon carbide as the new knife. You can also choose 46#'s.Luoyang abrasive tools professional sales all kinds of grinding wheel, carbide blade, diamond grinding wheel
