Product introducton

1 Calcium Silicon is compound alloy which is composed of silicon, calcium and ferro.

2 It is an ideal compound deoxidizer and desulfurizer which can be used in the production of many kinds of steel such as rail steel, low carbon steel, stainless steel and other special alloy like Ni base alloy and titanium base alloy.

3 CaSi alloy also can be applied as the heatraiser in convertor steelmaking workshop and as the inoculant or additive in producing cast iron and nodular cast iron.

4 factory very low price calcium silicon /calcium silcon powder /calcium silicon cored wire.Si content 50--65%,Ca 28--35%.

Calcium silicon cored wire

Q: In addition, the same furnace products out, the standard sample bar is qualified, no hole, but YT14 blade has more holes, why is that ah?: 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: 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 grinding carbide wheels?: The diamond grinding wheel has the advantages of high efficiency, high accuracy and good roughness!

Q: Hard alloy die polishing with what can be reached Ukraine black brightness: What if this need to die, the smaller diameter must be black if the large diameter is bright, with a diamond grinding paste and polishing powder

Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?: The bending strength of YG20 can reach 2500, which is suitable for making stamping dies. The bending strength of YG15 and JK13 can reach 2550, and the bending strength of JK15 can reach 2600, but the wear resistance is lower. The flexural strength of JK1 is 2500, and it has good wear resistance.

Q: The welding welding hard alloy cutter, should use what type of flame why: With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be

Q: What about cemented carbide produced in Zhuzhou? What brand is good?: Is good at home, as for the brand well of course is diamond, refined into a brand is also good, there are fine into hard alloy sales company, previously entered a large red facade, product is very much, the Diamond Road No. 24-5, hope to help to you.

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: What are the carbide inserts on the turning tool welded to the handle?: Burn copper on the knife rest.Pour the borax onto it.Put the alloy blade on it.Borax fell on the alloy blade top with flame cutting money.Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly and cools naturally.
