FeSi 72 for making ductile cast iron

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.

FeSi 72 For Making Ductile Cast iron

Q: Can hard alloy be welded with silver electrode?: Hard alloy can use silver electrode welding, some more liquid silver wire than general tin brass or iron brass, the cost is too high, the strength level than the ordinary copper electrode should be higher, personal suggestions for the selection of copper base up instead of silver electrode, such as the WEWELDING 46 electrode (referred to as Odin Wei 46 If the strength of electrodes), the structure is higher than silver, if it is to achieve the high permeability, it is still the ideal to silver, only from the strength level, is not WEWELDING 46 copper based electrode.

Q: Now on the market scrap carbide blade (YG8 milling cutter) how much is one kilogram?: It has high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

Q: Carbon steel valves in Baidu LibraryThe temperature can reach 425 degrees, is not without welding carbide seal, who has no detailed material ah?,: What valve do you have to see and hardening?. Usually only about 300 degrees. Special hardening can only be done at 425 degrees

Q: What material is that ultrafine cemented carbide?: You mean the ultra-fine grain cemented carbide, generally we have 0.6 alloy grain size is fine, which belongs to the tungsten carbide base hard alloy, ordinary tungsten carbide base hard alloy strength and hardness are higher than the same cobalt content. The process is mainly mixing, wetting, drying, forming, sintering, finishing, such as sand blasting, CVD/PVD coating, heat treatment, etc.

Q: What is the difference between hard alloy and steel: Tungsten carbide hard alloy belongs to, but not necessarily tungsten steel, now Taiwan and Southeast Asian countries customers love to use the word if they talk with tungsten, carefully into the deep, we will find that most of us. Or to the hard alloy and tungsten steel the difference is: also called hard alloy tool steel or high speed steel, tungsten steel is the raw material for smelting molten steel in steelmaking process for adding tungsten as a, also called high speed steel or tool steel, the tungsten content in 15-25%, The hard alloy is used; powder metallurgy of tungsten carbide as subject and cobalt or other metal bonded together and sintered, the tungsten content of more than 80% in general. Simply put all the hardness more than HRC65 as long as things go can be called cemented carbide alloyIs a kind of tungsten carbide hardness between HRC85 and 92, is often used as a knife

Q: What are the well-known brands of cemented carbide materials at home and abroad?: Foreign - Sweden Sandvik, Germany - Luxemburg, American Kenna, Israel - Domestic - hard line iscar; diamond, Zigong the Great Wall, Xiamen gol-egret etc..Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q: Carbide saw blades, plain and alternating teeth. What do you mean? That good?: Kunshan Feng rui1 tool company to provide technical information:The whole tooth tooth alternately around the turn, is used in the wood. The ladder tooth, generally used for cutting aluminum. So choose what kind of tooth shape is based on what cutting material to choose, and not good or bad points.How to choose the profile of alloy saw bladeThe tooth shape of a commonly used alloy saw blade tooth (alternate teeth), flat teeth, ladder flat teeth (low gear), trapezoidal teeth (inverted conical teeth), dovetail teeth (Tuo Fengchi), and industrial grade does not see more of the three left and right, left and right flat teeth etc.

Q: Will the alloy produced at 400 watts be decarburization or carburizing?: This is not necessarily, the hard alloy sintering infiltration decarburization mainly in wet grinding your ingredients and carbon sintering process control, vacuum furnace gas in order to prevent the reaction of pure, alloy with oxygen in the air, infiltration and decarburization products have no direct relationship, of course if it is caused by the leakage of vacuum sintering furnace can not meet the requirements, will lead to the direction of decarburization alloy.

Q: What is the difference between the production process of ferrous powder metallurgy and cemented carbide?: After the Second World War, the rapid development of powder metallurgy technology, new production technology and technical equipment, new materials and products continue to emerge, develop some special materials manufacturing field, has become an important part in modern industry.

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.
