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.In the production of special steel and special alloys.Such as rail steel, mild steel, stainless steel, steel and nickel base alloy, titanium alloy, and other special alloy are available the calcium silicon alloy as deoxidizer.The calcium silicon alloy also for practice of converter steel workshop with increasing agent, the calcium silicon alloy can also be used for cast iron inoculant and additives in nodular iron production.

 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:What's the difference between high speed tool steel and carbide cutter?
However, hard alloy is more expensive and it is too hard, and it is also a problem for its own processing, which makes it difficult to make tools with more complicated shapes, such as twist drills, by hard alloy
Q:How can I buy carbide die on the Internet? Who can help?!
Go out and look for it. Someone will want to surf the Internet at home.
Q:How to polish the rough surface of cemented carbide?
Polish the surface of the cemented carbide surface by using diamond abrasive paste. When polishing, can not cut short, should be in accordance with the first rough grinding paste polishing, and then use fine grinding paste polishing process, and can not be directly polished with fine abrasive paste. Otherwise, the surface of the material will leave a wavy corrugation, which will be difficult to be polished with fine abrasive. In addition, the grinding efficiency of fine grinding paste is much lower than that of coarse paste.
Q:What kinds of carbide knives do you have? Write out its main functions and uses.
(2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT), such as YT5, YT15, YT30 and so on.Because of the hardness and melting point of TiC is higher than WC, so compared with YG, its hardness, wear resistance, red hardness increase, bonding temperature is high, antioxidant ability is strong, and in high temperature will produce TiO 2, can reduce bonding. But the thermal conductivity is poor and the bending strength is low, so it is suitable for the processing of steel and other tough materials.
Q:Can carbide drills be used for high speed steel twist drills?
If not drill quenching steel, or stainless steel material, usually try not to use the hard alloy bit, the reason is that the hard alloy bit is easily broken, unless the non use of the situation, will use the hard alloy bit. The use of high-speed steel drills is sufficient to meet the needs of the job.
Q:Carbide cutters can work on materials of higher hardness
YG3A, Y6A, Y726, etc. can be processed more than HRC60 hardness hardness of the material.
Q:What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?
There are two reasons1. The tool itself quality problems of our factory has been recommended 3-turn Kuwait this brand2. Just the material, good hardness of material, speed, feed, reduce the point properly, can protect the tool wear well
Q:The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason
The cutter model is wrong, the milling can not move the material, the resistance is big, then the knife breaks. Use 75 degrees to make the plane
Q:Carbide products which are used more?
Sealing rings in the sealing industry, mould industry, machine tools, milling cutters, drill bits in the mining industry, and armor piercing shells in the army, etc.
Q:What are the carbide inserts on the turning tool welded to the handle?
The first copper burned in the post, and then the borax fell on the top, then put on top of the alloy blade, borax fell on the alloy blade above the flame cutting with money. Be careful not to use the high pressure oxygen valve. Wait until the copper water flows out evenly. Let him cool naturally,
