Purpose of Ferro Silicon Inoculant

1)improve the homogeneity of the cast iron structure

2)eliminate the formation of carbides into thin parts or salient angles

3)direct the solidification towards the stable diagram, with graphite precipitation

4)refine the structure (higher cells count, finer grains in the microstructure)

5)improve mechanical properties

6)better separate slag and metal

7)decrease the tendency to dross formation

8)decrease tendency of micro-shrinkage

9)decrease risk of gas formation

10)decrease risk of mold / metal interface defects

Q:What material is that ultrafine cemented carbide?
You mean the ultra-fine grain cemented carbide, generally we have 0.6 alloy grain size is fine, which belongs to the tungsten carbide base hard alloy, ordinary tungsten carbide base hard alloy strength and hardness are higher than the same cobalt content. The process is mainly mixing, wetting, drying, forming, sintering, finishing, such as sand blasting, CVD/PVD coating, heat treatment, etc.
Q:What is the resistivity of the yg13 cemented carbide?
A brief introduction to YG13, tungsten steelYG13 is a kind of tungsten steel tungsten steel mold suitable for production of complex shape of the tungsten carbide, which is up to 4000MPa to its bending strength impact resistance performance is excellent, especially YG13 tungsten steel with moderate hardness, low pressure sintering is made of fine grain 0.6um alloy powder with high strength, good abrasion resistance by the large number of customers die trial, recognized by all say the same thing it is indeed a high ratio of tungsten steel mold materials, especially suitable for the production of powder pressing mould.
Q:What is the reason for the metallographic cavity (as shown in the drawing) of cemented carbide?
YT14 alloy you said, if the above holes can start from the following aspects, 1, raw materials, dirty and high oxygen content, impurity content, sintering, 2.If the hole shape of the dirty and dirty, you can see some holes around a circle with cobalt layer, small holes are filled with cobalt, cobalt pool formation, if not pressure, hole like narrow shape.
Q:What are the cemented carbides?
General tungsten cobalt alloy is mainly applicable to: carbide cutting tools, molds and mineral products. Carbide cutting toolTungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.
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 hard metal is welded with stainless steel?
Braze welding can be used.Carbide containing tungsten, vanadium and other metals, melting point higher than stainless steel, can be considered
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 die how to calculate weight, that is to say, its kg weight
The density of tungsten, cobalt and titanium carbide is 9.7~13.2, and the higher the content of titanium carbide, the lower the density.
Q:Is the hard alloy the same as the cemented carbide?
Dissimilarity!Cemented carbide refers to one or more refractory metal carbides (WC, TiC, etc.) as hard phases, and transition metals (Co, etc.) as bonding phases and multiphase materials prepared by powder metallurgy technology. As carbide tools for cutting tools, the commonly used carbides are WC, TiC, TaC, NbC and so on. The commonly used bonding phases are Co, Ni, Fe and so on. The strength of cemented carbide depends mainly on the content of the binder phase.The ultra-fine Grain Cemented Carbide Kennametal company launched a new brand KC5525, KC5510 uses the high cobalt hard alloy matrix grain refinement, cemented carbide substrate with super grain refinement cobalt content up to 10%, with TiAlNPVD coating with high aluminum content, the tools in intermittent cutting with high edge toughness at the same time, also has a very strong deformation resistance. ISCAR company for solid carbide end mills "AL-TEC" brand series of coating, with ultra-fine Grain Cemented Carbide with high aluminum content, TiAlN (PVD) coating, which in milling high hardness of 60 ~ 62HRC hardened steel, compared with the original IC903 grade, improve tool life 150%. Valenite company for cast iron in high-speed turning VP1595 grades, but also in the ultra-fine grain cemented carbide substrate, using MT-CVD coated with 18 m thick TiCN/Al2O3/TiC coating, the flank is coated with a layer of gray TiC, in order to facilitate and blade rotation observing the wear of cutting edge, the grade in rough machining ductile iron, the processing efficiency than other K05 ~ K10 grade increased by 50%.
Q:What is hard alloy grinding?
Green silicon carbide grinding wheel, green silicon carbide hardness brittleness is higher than black silicon carbide, abrasive sharp, good thermal conductivity, suitable for grinding hard alloy, optical glass, ceramics and other hard brittle materialThe diamond grinding wheel than boron carbide, silicon carbide, corundum and other general grinding blade grain made of sharp corner, small abrasion, long service life, high productivity, good processing quality, but the price is expensive, it is suitable for the grinding of hard alloy, ceramic, semiconductor and other high hardness brittle hard material.
