Ferro silicon Inoculant

Fesi inoculant

An extensive range of ferro silicon inoculants are available with various combinations of active inoculating elements including Barium, Calcium.

Specs of Inoculants

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

FeSi Inoculant Used In Steel Making

Q: YW1 what do you mean by "YW" in carbide cutter head?: Y represents the metallurgical (Yejin) Department standard. W stands for universal (Wanneng) alloy

Q: What are the standard units of measurement for carbide inserts?: Manufacturers usually use KG, which is used inside the shop

Q: What is the difference between hard alloy and steel: Products: tungsten steel containing approximately 18% tungsten alloy steel, tungsten steel belongs to hard alloy, also called tungsten titanium alloy. The hardness for the Vivtorinox 10K, second only to diamond. Because of this, tungsten steel products (a common watch), has the characteristics of not easy to be worn. Commonly used in lathe tool, drill, impact drill glass knife head, tile cutter, hard annealing, but brittle. Hard alloy: powder metallurgy hard alloy belongs to the category of metal ceramic is also known as metal carbides (WC, TaC, TiC, NbC, etc.) or metal oxide (such as Al2O3, ZrO2 etc.) as the main ingredient, adding proper amount of metal powder (Co Cr, Mo, Fe, Ni, etc.) made by powder metallurgy method, has some characteristics of metal ceramic.

Q: The existing 60*60 standard cast iron plate, above 3 hard alloy welding specifications, probably in the 30*30, in which the appropriate welding method, know the friends willing to enlighten ah, thanks in advance.Some friends have said the binder is a copper brazing, the basic can be settled. As far as I know, many methods such as welding, high frequency welding, oxygen welding, I want to find a kind of welding method. The key is to understand the trouble with us, surface and surface welding: 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 the coefficient of thermal expansion of cemented carbides?: [classification of cemented carbide]1, tungsten cobalt carbide: the main component is tungsten carbide (WC) and binder cobalt (Co). The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.2, tungsten titanium cobalt carbide: the 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.3, tungsten titanium tantalum (NB): hard alloy is the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. thisThis kind of hard alloy is also called universal cemented carbide or universal hard alloy. The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number.

Q: What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?: Hard alloy is one of the people familiar with the tools and materials, it is very difficult to weld by hard metal carbides (we, Tie) of powder metallurgy with CO, MO and NI as sintering binder. Its mechanical, physical and mechanical properties depend mainly on the kinds of metal carbides, properties, quantities, grain sizes, types and components of binders.In cemented carbides, the proper addition of Tie increases the content of hard Tic, and the higher the hardness of the alloy. The more the content of cobalt in the bonding phase, the lower the hardness of the alloy. Therefore, the hardness of We-Tie-eo alloy is higher than that of We-eo alloy. The hardness of We-eo alloy can be increased by adding Tae or Nbc. The higher the hardness of the cemented carbide, the better the wear resistance, but the lower the strength (bending), and the addition of Tac will improve the blade strength, while strengthening the blade resistance to fragmentation and breakage, fatigue strength also increased. Generally, the higher the hardness, the lower the toughness. In China's Cemented Carbide standard YB850-75, most carbide grades are We-Co (YG) and We-Tie-Co (YT) two.Domestic hardness alloy grade control: GB, brand ISO, P10, P20, M10, M20, K01, K10, K20, K30, domestic uniform brand YT15, YT14, YT5, YW1, YW2, YG3, P30, YG6x, YG6, YG8

Q: What type of emery grinding machine is 3000/min for grinding carbide turning tools (e.g., YG8.YS8.YT15.YW1, etc.)?: Diamond grinding wheel, green carborundum wheel can be used. Two, choose one, or choose the former good. Diamond grinding wheel has the advantages of less wear, long life, high productivity and good processing quality, that is, the price is a little more expensive.

Q: Is the hard alloy the same as the cemented carbide?: The CBN price is a little high. If you can't accept it, you can consider using the ceramic cutter to test the PCBN (CBN) blade. Ceramic blades can not work (he is brittle, easy to crack), super hard tool sales

Q: Can carbide drills be used for high speed steel twist drills?: Now, like OSG's drill, mainly carbide based.

Q: Do you want to center hole? How deep is fit? Or do not hit it directly? My drill bit and the center hole contact point are easy to collapse: Detailed analysis of the specific circumstances, the general drilling site is very smooth, you do not need to hit the center hole. If the borehole is uneven or drilled on the slope, a center hole is required. If the drill hole is first deflected and re corrected, a center hole is also required.
