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.

Pictures of FeSi 70:
- Q: Carbide blade domestic that tricky point?
- Too much, there are at least dozens of domestic do this.
- Q: Carbide according to the structure of the words, what can be divided into?
- Hard alloy is by grade, can be made into all kinds of special-shaped parts
- Q: Welding hard alloy cutter, hard alloy cutter, high speed steel, ceramic knife head head are what are the advantages and shortcomings?
- Advantages of carbide drills:1. can be used for drilling more complex materials, you can choose a higher cutting speed.2., selection of alloy drill special high-performance alloy blade, effectively reduce the avalanche knife, and maintain good wear resistance.3. multi layer geometry cutting end blade improves discharge performance and maintains smaller cutting resistance.4., in addition to the commonly used right angle stem, there are a variety of handle type, suitable for a variety of drilling machines, drilling machine matching.Disadvantages of carbide drills:The advantages of carbide drill can drill more hard material, the disadvantage is to be good grinding, grinding is not good, easy to break the edge, two main cutting edge height and angle equivalent, it is best to use the grinding machine.
- Q: Is there any pollution in the production of cemented carbide?
- The main pollutants in the production of cemented carbide are dust, waste residue and waste water, and the biggest influence on the environment is soot. According to regulations, waste gas can be divided into two categories: particulate matter, exhaust gas and gaseous pollutants. The exhaust gas of ferroalloy plant comes from ore smelting furnace, refining electric furnace, roasting rotary kiln, multi layer mechanical baking furnace and aluminum metal smelting furnace. Ferroalloy plant exhaust emissions, dust concentration is high, 90% of exhaust gas is silicon dioxide, but also contains chlorine, nitrogen oxides, carbon monoxide, sulfur dioxide and so on. Waste residue and waste water are the most serious pollution of chromium compounds, and there are also pollution of nickel compounds.The State Economic and Trade Commission, the State Environmental Protection Administration and other departments also jointly issued "on accelerating the restructuring of China's ferroalloy industry views" (in the economic and trade industry [1999]633), from 1999 to 2005, to stop the new types of ferroalloy electric furnace (kiln) and blast furnace.
- Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?
- The wear resistance of cemented carbide is related to the proportion of titanium carbide and cobalt carbide contained in it. It contains more titanium carbide, less cobalt content, higher hardness and better wear resistance. But brittleness also increases, easy to break the edge, so it is suitable for finishing.
- Q: Carbide saw blades, plain and alternating teeth. What do you mean? That good?
- .1., about the most widely used teeth, cutting speed, grinding relatively simple. Suitable for cutting and crosscut various soft and hard wood materials and MDF, plywood, particleboard etc.. Equipped with anti elastic protection around the tooth is tooth plate for dovetail, longitudinal cutting of various degree; with negative rake angle of tooth saw blade sharp, serrated cutting because of good quality, usually used for veneer cutting.2. flat tooth saw is rough, cutting speed is slow, grinding is the most simple. Mainly used for sawing ordinary wood, the cost is lower, more used for smaller diameter aluminum saw blade, in order to maintain cutting to reduce adhesion, or used for grooving saw blade, to keep the groove bottom leveling.
- Q: Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!
- Another case is that the chemicals in the polishing fluid react with the Co phase in the alloy, causing the Co to overflow or Co to deposit again, so that you need to consider whether you need to replace the polishing fluid.
- Q: What are the common kinds of cemented carbides?
- Cemented carbide is a hard particle of refractory metals (tungsten, tantalum, titanium, molybdenum, etc.) that is mixed with one or more iron elements (cobalt, nickel, or iron), pressed and molded, and then sintered. Types and properties of cemented carbides: (1) classification and grade of cemented carbides. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide (WC) and binder cobalt (Co). The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt. For example, YG8 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbide. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide. For example, YT15 represents an average WTi = 15%, while the others are tungsten titanium cobalt carbide with tungsten carbide and cobalt content. The tungsten titanium tantalum (NB) hard alloy is the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.
- Q: How are cemented carbides separated from the cutting tools?
- The hard alloy cutter head and the tool body junction part are heated to 600~800 degrees, and the solder can be melted, and the cutter head and the cutter body of the carbide cutter can be separated.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: allowing the use of larger anterior angle, generally high speed steel tool than the hard alloy tool angle _______.A0 degrees ~5 degrees, B6 degrees, ~10 degrees, C11 degrees, ~15 degrees
- Different rake rake angle and carbide cutting tools of high-speed steel cutting tools, but according to different materials, the front angle and cemented carbide cutting tools of high-speed steel cutting tool rake angle difference is different;
