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:How can I buy carbide die on the Internet? Who can help?!
The mould made from the same carbide alloy made from Zhuzhou will not be sold.
Q:What kind of carbide alloy is used in stainless steel processing?
Such as: YA6; YH1; YW3. This kind of steel has high hardness, small amount of feed to lower cutting speed, cutting the depth is bigger, avoid hardening layer on the surface of the skin with the previous procedure (Note 2).
Q:Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?
The main component of the tungsten steel milling cutter in cemented carbide is tungsten carbide, tungsten steel on steel hardness and heat resistance are significantly improved, but the toughness decreased sharply.
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 type of carbide for punching dies? Better. Where can I buy it?
Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
Q:Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy
Ha ha, I'm good at that!HC is the sign of the attractive magnetic force of the alloy, and HRA is the sign of hardness. COM is the cobalt magnetic mark of the alloy. D is the density of the alloy. The general quality certificate of the alloy product will have three indexes above
Q:The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason
Hard to turn materials require different speeds and special turning tools. There is a reasonable amount of feed. Ordinary alloy knives are very easy to break
Q:Several hard alloy cutter lathe with?
YG car, pig iron and so on, YT, steel and the like, high temperature resistant, YW car alloy steel, the highest strength.
Q:What is the specific gravity of cemented carbide?
Similar to mercury. Tungsten cobalt carbide 14.4~15.3 density, tungsten, cobalt, titanium carbide 9.7~13.2 density, can float in the mercury is a steel knife, sink into the mercury is a cast iron knife
Q:What is the base material of carbide saw blade?
Carbide saw blades include the kinds of alloy cutters, matrix materials, diameter, tooth number, thickness, tooth shape, angle, aperture and so on. These parameters determine the machining ability and cutting performance of saw blades. In selecting the saw blade, it is necessary to select the saw blade according to the kind, thickness, sawing speed, cutting direction, feeding speed and width of saw.
