The introduction of the ferro silicon 75%
The introduction of the ferro silicon
Ferrosilicon has been widely applied.in the steel industry, foundry industry and other industrial production.
Ferrosilicon is indispensable deoxidizer in the steel industry., ferrosilicon is used for precipitation deoxidation and diffusion deoxidation in Ju steel. Brick iron also as an alloying agent used in steelmaking. Adding a certain amount silicon to the steel can significantly improve the strength, hardness,elasticity and permeability of steel, reduce the hysteresis loss of transformer steel.
High ferrosilicon or silicon alloys is used for the production of low-carbon reductant in ferroalloy industry. Adding ferrosilicon to cast iron can be inoculant for ductile iron, and can prevent the formation of carbides, and promote the precipitation of graphite and the nodulizing, so as to improve performance of cast iron.
In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry,and coatings for welding electrodes in the electrode manufacturing
The application of the ferro silicon 75%
(1) in the steel industry used as deoxidizer and alloying agents.
(2) in the iron industry used as a nucleating agent and spheroidizing agent. Cast iron is a kind of important modern industrial metal materials, it is much cheaper than steel, easy to melt refining, excellent casting performance and seismic capacity is far better than steel. Especially the nodular cast iron, its mechanical performance at or near the steel mechanical property. Add a certain amount of silicon in cast iron can prevent iron in formation and precipitation of carbides, and promote the graphite spheroidizing, therefore in the nodular iron production, ferrosilicon inoculants is a kind of important separation graphite (help) and spheroidizing agent.
(3) used as a reductant in ferroalloy production. Not only chemical affinity between silicon and oxygen is very big, but also high silicon silicon carbon content is very low. So high silicon ferrosilicon (or siliceous alloy) is a low-carbon ferroalloy ferroalloy industry production more commonly used a reducing agent.
- Q: suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?
- Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced
- Q: How much is a kilogram of cemented carbide now recycled?
- Scrap alloy depends on what you are.The blade depends on the brandAlloy products depend on cobalt contentTalent pricing.
- Q: What is the specific gravity of cemented carbide?
- The carbon content of WC theory is 6.128% (atom 50%). When the carbon content of WC is greater than the theoretical carbon content, the free carbon (WC+C) appears in WC. The existence of free carbon leads to the growth of WC grain around it, resulting in uneven grain of cemented carbide. General requirements of tungsten carbide compound carbon high (more than 6.07%), free carbon (less than 0.05%), the total carbon depends on hard alloy production process and use scope.Under normal circumstances, the total WC carbon content in the vacuum sintering process of the paraffin process is mainly determined by the combined oxygen content in the block prior to sintering. An oxygen content should be increased by 0.75 parts of carbon, that is, WC total carbon, =6.13%+ oxygen content,% * 0.75 (assuming the sintering furnace is neutral atmosphere, in fact, most of the vacuum furnace is carburizing atmosphere, and the total carbon content of WC is less than the calculated value).At present, China's total carbon content of WC is roughly divided into three kinds: paraffin process, vacuum sintering, the total carbon content of WC is about 6.18 + 0.03% (free carbon will increase). The total carbon content of WC for hydrogen sintering of paraffin process is 6.13 + 0.03%. For rubber process, WC total carbon =5.90 + 0.03% is used for hydrogen sintering. The process is sometimes interleaved, so the determination of WC total carbon should be based on specific circumstances.
- 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: Material properties of Cemented Carbides
- Metal carbides, especially B, B, IV V VI B metal carbide melting point is above 3273K, the TAC hafnium carbide, respectively 4160K and 4150K, is the highest point currently know material. Most of the carbide hardness large, their microhardness is higher than 1800kg mm2 (micro hardness is hardness says one way for hard alloy and hard compound, microhardness 1800kg mm2 is equivalent to a diamond a Mohs hardness of 9). Many carbides are difficult to break down at high temperatures, and their antioxidant power is stronger than their constituent metals. Titanium carbide has the best thermal stability in all carbides, and is a very important metal type carbide. However, in an oxidizing atmosphere, all carbides are readily oxidized at high temperatures, which can be said to be a major weakness of carbides. In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids of the metal lattices and form interstitial solid solutions. They are similar to the gap carbide in that they can conduct electricity, heat conduction, high melting point, high hardness and great brittleness at the same time. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 DEG C.
- Q: How to solve the severe wear of the flank of the carbide blade during machining?
- In the process of carbide blade machining, the flank wear is mainly due to the excessive cutting temperature.Major solutions:1, choose the better wear resistance of lower grades, cutting speed, large angle blade, choose sword sharp radius, blade angle blade, please solve according to the specific situation of processing;
- Q: Processing stainless steel 301 milling thickness of about 3 millimeters, with what blade good?
- Friends, according to your question, if change my words, I choose YS25Grade ISO grouping, code name, density, bending strength, hardness, useYS25 12.8 P25 13.2 = 1780 = 90.5 for carbon steel, cast steel, high manganese steel, high strengthRough turning, milling and planing of steel and alloy steelYou mainly milling the surface is not refined, there is no need to use that good, in one is YS25, cheap, well, that's it, if there is any good advice to my replies
- Q: What is the base material of carbide saw blade?
- Carbide saw blades include the kinds of alloy cutters, matrix materials, diameter, tooth number, thickness, tooth shape, angle, aperture and so on. These parameters determine the machining ability and cutting performance of saw blades. In selecting the saw blade, it is necessary to select the saw blade according to the kind, thickness, sawing speed, cutting direction, feeding speed and width of saw.
- Q: The difference between cemented carbide and tungsten.
- The market is usually called tungsten carbide, the two are the same, and the high speed steel called high speed steel. This is the old habit of name of state owned enterprises.
- Q: Import all carbide drill bit, mainly those brands
- Domestic is so cheap, why use foreign diamond brand is very good?
