FeSi 70 for Casting Manufactural and Steel Making

 

Description of FeSi 70

 

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 of FeSi 70

 

1)As de-oxidation and alloying agent in iron & steel plants.

2)Enhance properties including ductility, strength, rigidity and resistance of steel.

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:In addition, the same furnace products out, the standard sample bar is qualified, no hole, but YT14 blade has more holes, why is that ah?
Too many factors, but according to the shape, size, number and distribution state can be roughly determined what caused by links.
Q:Printing requirements for cemented carbide
Because of its superior properties such as high strength, hardness, excellent wear resistance and oxidation resistance, carbide is widely used in mechanical processing, petroleum mining, mold forming and structural wear-resistant parts and other fields. In the production of cemented carbide, sintering is the most important process. Even if the compacts are the same, different sintering processes have different effects on the properties of the sintered products. For a long time, many researchers have gradually formed a variety of sintering methods in actual production, including vacuum sintering, hot isostatic pressing sintering, vacuum follow-up hot isostatic pressing, sintering, hot isostatic pressing, etc..
Q:I want to process more hard stainless steel, with YC45 this type of carbide knife can do? Where can I buy authentic, know the friend told me, thank you
If it is stainless steel (316 or 304), it is recommended that you use YG8 alloy cutter head, processing needs low speedWith sufficient cutting fluid, this stainless steel does not require any other cutting tools.Note: YG8 impact resistance, but not high temperature
Q:What is the difference between hard alloy steel and high speed steel?
3, hardness is not the same: cemented carbide hardness, especially at high temperature hardness, but high-speed steel toughness better4, can withstand the cutting speed is not the same: due to the red hard high, can withstand higher cutting speed, and high-speed steel is now not high speed
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:Tungsten steel could be used to do is hard alloy knife?
You can do all kinds of data of tungsten steel tool, it can be a knife. There is little precision mould
Q:Compare the advantages and disadvantages of high speed steel and cemented carbide
High speed steel, high carbon steel, can be divided according to chemical composition of tungsten and molybdenum in steel, cutting performance is divided into high performance of ordinary high speed steel, high speed steel. Through strengthening heat treatment of high speed steel.
Q:What is the difference between them?From hardness, abrasion resistance analysis!
A total of 10 ~ 25%. Under the condition of heat generated in the high-speed cutting (about 500 C) can still maintain a high hardness of HRC can be more than 60. This is the main characteristic of high speed steel - red hardness. And carbon tool steel after quenching and low temperature tempering, at room temperature has very high hardness, But when the temperature is higher than 200 DEG C, the hardness decreased rapidly, at 500 DEG C hardness has been reduced to a similar degree with annealing state, completely lost the ability of metal cutting, which limits the production of carbon tool steel and high-speed steel cutting tools. The red hardness, make up for the fatal defect of steel with carbon. That can be used in the manufacture of cutting tools.
Q:Make cutting dosage
But modern machining, has no strict distinction between the T and G class, but in different types of processed materials and processing conditions, different ways such as the use of different materials, and with appropriate coating, to reduce the cost requirements.Cutting parameters need to be selected according to different cutting occasions and different materials to be machined.
