FeSi Alloy As Good Deoxidizer

Magnesium Alloy Plate/Sheet AZ31 AZ61 AZ91

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: What is called cemented carbide?: 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 are widely used as tool materials. 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. Hundreds of times now cutting speed of new carbide tool is carbon steel.Carbide can also be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal abrasives, cylinder liner, precision bearings, nozzles and so onIn the past twenty years, coated carbide also come out in Sweden.1969 in the successful development of titanium carbide coated tools, the tool is a matrix of tungsten carbide titanium carbide cobalt alloy or cobalt tungsten carbide, titanium carbide surface coating thickness of only a few microns, but with the same grade alloy tool compared to prolong the service life of 3 times, cutting to increase the speed of 25% ~ 50%.20 in 70s has been fourth generation coating tools, can be used for cutting hard processing materials.

Q: What kind of cemented carbide is the most wearable?: Carbide wear is due to the grain size and the cobalt content determines the finer granularity of cobalt content is lower, the higher hardness and lower hardness should be mentioned is the selection of wear-resistant hard alloy not only the hardness to see the use of general cutting hard alloy material with YW2 a relatively high hardness but if the working conditions impact operations more frequently if it should take into account its toughness but the toughness and hardness is conflicting under such circumstances can choose the class YG fine grain alloy

Q: HSS clip can clamp the hard alloy saw it: A straight back; often used in fine toothed finishing mills. Both the curve and the back teeth have good strength and can bear heavy cutting load. They are often used in coarse tooth mills.Relieving cutterThe back is made by the method of shovel (or grinding), which is machined into the back of the spiral of Archimedes. The cutter only needs to be regrinding before it is blunt, and the original tooth shape can be kept unchanged. It is used to make all kinds of formed milling cutters such as gears and milling cutters.

Q: In addition to diamonds, Hunan there are no good carbide manufacturers? Product advantages in the ordinary blade, knife head and mining tools. Which factory's alloy is of good quality? The best size, with the original tungsten powder. Please know what to say, first thank you: Looking for packing box manufacturers can find the letter plastic

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: We'll drill on the stainless steel column. Which bit is better?: If it's cylindrical carbide, it's better to be on the drill bit or as a guide

Q: I would like to use carbide cutting tools, car work, ordinary A3 steel or 45 steel, lathe speed to play more appropriate, the workpiece surface quality is better?: LZ, I don't know if you did it for eight years or eight years. When you finish the car hit 1600 turn, your knife is a diamond? I'll ask you to open 6 is the number of mid-range lathe wire ah, the general lathe open open 6 mid-range at least twenty-six wire, when you finish turning with so high feed! Even if you use 1600 rpm and this knife, your surface is bright, but your workpiece roughness must be unqualified. Remember, finish is not roughness. You are good at the question. The cutting speed is based on what kind of cutting depth and amount of knife you choose when you rough the car. You don't say the exact size of the part you want to process. That's not good. The key experience is to rely on their own step by step, tired.

Q: 5 meters long hard alloy bars, where are they sold?: Because of being restricted by the conditions of equipment for the production of hard alloy long alloy strip production generally more difficult, even if the production price is not expensive, you can consider the method of sectional concrete can look at Zhuzhou with a hard alloy.

Q: The difference between cemented carbide and tungsten.: 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: In the car, titanium alloy, high speed steel cutting tool rake angle to 20 degrees angle than the carbide cutter. However, different the material should choose different rake angles, and not a fixed angle value.
