FERRO SILICON

Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

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: Are there any German products called K44 which are imported into cemented carbide materials? I am machining hole, K44 is better than domestic material K30?: Yes, K44 is a German cobalt collar carbide material.German cobalt collar is the world's third largest rotating cutter manufacturer, with more than 100 years manufacturingCobalt collar: metal hole cutting tool history, including in the United States, Britain, Brazil, Japan, Korea, Czech and other nineteen countries set up factories. The main production, sale and repair all kinds of metal hole cutting tools, all of its main equipment imported from germany. At present, the tool grinding, grinding and grinding center has a modern five axis CNC intelligent cutting tool grinder,The automatic coating equipment and precision universal cutting tool measuring equipment which can be coated with many kinds of coatings, is mainly responsible for grinding, grinding and grinding all kinds of high speed steel and grinding hard alloy milling cutters and hole cutting tools.

Q: What is hard alloy steel?: Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.

Q: Detailed comparison of cemented carbide with diamond properties: At present, the drill bit above the 981 offshore oil platform, which is being drilled in the South China Sea, is a typical diamond tool, which requires a high level of technology.At present, due to the rapid development of the diamond industry, a lot of new diamond tools are being developed at a very fast speed, some of which are far superior to the traditional cemented carbide tools in performance. With the development of the times, the depletion of metal resources, I believe that more than 80% of carbide applications will be replaced by diamond tools. As a green energy, diamond is showing great vitality.

Q: What are the differences between the two grades of carbide, YT15 and YT5?: YT15 is compared to YT5. The former has high hardness, great brittleness and good wear resistance. The latter is low in hardness, tough in toughness and poor in wear resistance. YT5 is often used for roughing or machining, impact cutting, and YT15 is usually semi finishing and finishing.

Q: Welding hard alloy cutter, hard alloy cutter, high speed steel, ceramic knife head head are what are the advantages and shortcomings?: The advantages of carbide drill can drill more hard material, the disadvantage is to be good grinding, grinding is not good, easy to break the edge, two main cutting edge height and angle equivalent, it is best to use the grinding machine.

Q: the blade is hard alloy, the processing material is QT600, the plane lower tool margin is 4mm, the speed and the knife: This belongs to the category of ductile iron, more difficult to process, because the material is hard particles, it is recommended around S=1200 F=400

Q: One kind of steel is called T10, and another is carbon steel. What kind of hardness and strength do they have?: 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: After welding, and then sharpening, grinding into 4 Pyramid shape, and then used to knock stone, which is not easy to bad, which is more durable? Model number is D224, I would like to ask you, which should I buy? I'm mainly used for knocking stones.: YG8 is suitable for YG6 with higher hardness, but less impact toughness

Q: How are cemented carbides sintered?: Hard alloy with high hardness of refractory metal carbides (WC, TiC) micron powder as the main ingredient, with cobalt or nickel (Co) (Ni), molybdenum (Mo) as the binder, powder metallurgy products in vacuum furnace or hydrogen reduction sintering furnace. In the manufacture of cemented carbide, the size of the raw material powder is between 1~2 microns and the purity is very high.
