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:I would like to ask cemented carbide grade YK15,
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:What is the coefficient of thermal expansion of cemented carbides?
The thermal expansion coefficient of cemented carbide is about 6*10^ (-6) / C, and there is a slight difference according to the type of cemented carbide
Q:Does the hard alloy belong to the composite material?
1. carbide is based on tungsten carbide as matrix, cobalt as binder, according to the needs of the titanium, tantalum, niobium and other metals to obtain the "alloy" material.2. because this alloy is relatively hard, so called him "carbide", people often used to do machining tools.3., from the definition of "composite material", "alloy" belongs to "composite material"". Therefore, cemented carbide belongs to composite material.
Q:What kind of carbide alloy is used in stainless steel processing?
Machine tool steel. Better cooling, liquid viscosity and sulfur chosen for good cooling performance, the pressure of the cooling liquid chlorine.
Q:What are the grinding carbide wheels?
The diamond grinding wheel has the advantages of high efficiency, high accuracy and good roughness!
Q:Why carbide fracture?
First you have to choose the right material. Various uses must choose the relative grade, and also has the material which you use, has the sundry inside
Q:What are the cemented carbide coatings?
The hard alloy coating is used to form high hardness wear-resistant coating on the surface of metal, Beijing Naimo company according to the composition of the alloy is divided into:1.jp8000 spraying tungsten carbide coating2. nickel tungsten alloy coating3. cobalt tungsten alloy coating
Q:What are the common kinds of cemented carbides?
The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number, such as YW1. (2) grade, composition, performance and application of commonly used hard alloy (see table below) categories of chemical composition of W/% grade performance scope of tungsten cobalt alloy YG3X 96.5 - < 0.53 for cast iron, nonferrous metals and alloy fine boring, fine car, can also be used for fine machining of alloy steel, Quenched steel and tungsten and molybdenum materials; high tungsten carbide content, binder content is low, its high hardness, flexural strength is low; therefore, YG3 is suitable for finishing; whereas the YG15 can bear larger load, suitable for roughing. Suitable for cast iron, nonferrous metals and alloys and non metallic materials roughing during continuous cutting, interrupted cutting of the semi refined car, fine car for percussive rotary drilling machine drilling hard rock, containing coal cutter teeth, hard rock drill, well drilling hard rock percussion drill bit, stamping die, planer and knife for percussive rotary drilling machine and other chisel hard and extremely hard rock, in the epidermis processing great work under stress perforation and stamping tools tungsten titanium cobalt alloy YT5 855 - 10 for carbon steel, alloy steel, forging, stamping, casting, uneven section, rough turning, discontinuous cutting the rough plane semi finishing.
Q:What about cemented carbide produced in Zhuzhou? What brand is good?
Diamond brand still has a certain position, the 1 floor said that the fine carbide sales company, I pass there every day, but also put Alibaba lights in there
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.
