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.

The specification of Ferro Silicon (55%, 65%, 70%, 75%, 80%, etc.) :

Packing: In plastic woven bags of 1,000kg net each.

Q: Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?: The main component of the tungsten steel milling cutter in cemented carbide is tungsten carbide, tungsten steel on steel hardness and heat resistance are significantly improved, but the toughness decreased sharply.

Q: How are hard alloy fittings machined and polished?: Cutting tools or ceramic cutting tools for cubic boron nitride material, cobalt alloy cutting tools, etc.,Diamond grinding materials for polishing.

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.

Q: What are the grinding carbide wheels?: Diamond grinding wheel, carborundum wheel and so on.The diamond wheel: the diamond abrasive were used as raw materials, metal powder, resin powder, ceramic and metal plating as binder, made of the central circular hole is called consolidation abrasive diamond wheel (alloy wheel).

Q: There are three kinds of cemented carbides, of which tungsten, cobalt and titanium are brittle cemented carbides?: Cemented carbides are classified into tungsten, cobalt, tungsten, titanium, tungsten, titanium, tantalum and cobalt. Tungsten cobalt carbide knife with: YG6, YG8, YG8N and so on, such carbide cutting tools for processing non-ferrous metals, stainless steel, cast iron and other materials;Tungsten carbide hard alloy knife has: YT5, YT15, etc., this kind of carbide cutting tools for processing steel and other tough materials;Tungsten, titanium, tantalum, cobalt carbide knife with: YW1, YW2, YS25, WS30, etc., this kind of carbide cutting tools for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.

Q: What kinds of carbides are there? How should we choose in production?: Tungsten cobalt carbide (YG): suitable for brittle materials such as cast iron;Tungsten cobalt titanium carbide (YT): it is suitable for processing plastic materials, such as steel;General purpose cemented carbide (YW): commonly used for processing stainless steel, heat-resistant steel, high manganese steel and other difficult to process materials.

Q: Carbide coated drill bit. Do you have one there?: 1. carbide drills are generally worn in the back. Then it has little influence on service life.2., the high strength of the workpiece material, easy to cause the front of the drill (spiral groove) wear, bit life impact.

Q: What are the types and specifications of carbide cutters?: Tungsten, titanium, tantalum (niobium) carbidesIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. The hard alloy and hard alloy general or universal hard alloy.The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number, such as the YW1. knife head has dozens of specifications, to be enumerated for reference!

Q: What is the heat treatment process of cemented carbide?: Responsible for this, you said, carbide heat treatment is deceptive theory, try to eliminate the gap, improve the purity of the fly.

Q: belong to raw material? After buying instockroom directly under the workshop to account for 5The company is small, no warehouse, do not fill in a single storage, the parts purchased directly to use, how to do?It's so complicated. Is there a simple way to do it?: Carbide grinding head, drill bit, tap, is a tool of low value, easy to wear goods.Welding wire, flux, welding rod and protective welding gas belong to raw material
