Product Description:

   Calcium and silicon and oxygen has a strong affinity.Especially calcium, not only with strong affinity, oxygen and sulfur, nitrogen has a strong affinity.So the calcium silicon alloy is a kind of ideal compound deoxidizer, desulfurization agent.Silicon alloy not only deoxidization ability strong, deoxidizing products tend to rise, easy to discharge, but also can improve the performance of the steel, plasticity, impact toughness of steel and liquidity.Currently the calcium silicon alloy can be final deoxidization instead of aluminium.Be applied to the high quality steel.

    Binary alloys of silicon and calcium, belongs to the category of ferroalloys.Its main ingredients for silicon and calcium, but also contain different amounts of iron, aluminum, carbon, sulfur and phosphorus and other impurities.Iron and steel industry as a calcium additive, deoxidizer, desulfurization agent and nonmetal inclusions denaturant.Used as a nucleating agent and denaturant cast iron industry.The calcium silicon alloy by calcium and silicon content of different is divided into:

Q:Fuzhou where to buy steel tungsten carbide
How will you buy the blade right I can express to you
Q:Is nickel base alloy hard alloy?
There are three kinds of cemented carbides used in machining,:1, YG--- tungsten cobalt alloy products, the YG6 is generally suitable for machining cast iron, roughing non-ferrous metals and their alloys and non metallic material during continuous cutting, interrupted cutting of semi fine fine cars and trucks etc..
Q:Does the hard alloy belong to the composite material?
Grain refinement can improve both the hardness and toughness of the material. Hard alloys and cermets belong to particle reinforced composites, which change the size of hard phase and have great influence on the properties. In this paper, the preparation process of cemented carbide and cermet raw powder with different thickness is optimized, and two sets of materials with the same original chemical composition and different grain size are prepared by vacuum sintering technology.This is not how I suggest you go to Baidu search Suzhou haokai metal material limited company to ask it!
Q:Carbide blade yc35 and YS25 what is the difference between which is suitable for processing stainless steel materials?
You mainly milling the surface is not refined, there is no need to use that good, in one is YS25, cheap, well, that's it, if there is any good advice to my replies
Q:K carbide carbide cutting tools, mainly used for turning what materials?
K class brand is the international standard ISO code, equivalent to China's class YG carbide brand, suitable for processing stainless steel, non-ferrous metals and alloys, as well as non-metallic materials, cast iron and other materials.
Q:What does WC refer to in cemented carbides?
Of or relating to an alloying element that is tungsten carbide.Tungsten cobalt carbideThe main ingredients are 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, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.
Q:How are hard alloy fittings machined and polished?
Cutting tools or ceramic cutting tools for cubic boron nitride material, cobalt alloy cutting tools, etc.,Diamond grinding materials for polishing.
Q:Carbide welding method 50
Then an old welder re - welded it once, and it worked out just now. Probably the main point is water welding, the flame can not blow the time is too long, alloy hair red, you have to immediately with the matrix together, right, not only faster, more important still prevail. Because it's not good to come second times if you're not allowed
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:Is the hard alloy the same as the cemented carbide?
Is essentially the same, are two kinds of powder alloy materials, but the composition is different, its processing performance depends on the alloy material of concrete, in my experience, super hard alloy toughness than hard alloy with high hardness, but lower than the hard alloy, don't be misled by the literal meaning, the word super tool hard alloy generally refers to add the other ingredients of high speed steel the hardness wear resistance than ordinary high speed steel (of course not hard alloy) without losing the advantages of high speed steel toughness.
