Product Description:

calcium carbide  is a grey salt of calcium (CaC) used in making acetylene

 

Application:

1、 Calcium carbide to generate acetylene after reaction with water to the synthesis of many organic compounds

2、  Heating powdered calcium carbide react with nitrogen gas, to generate calcium cyanamide, namely lime nitrogen, heating lime nitrogen and salt of black cyanide for gold mining and non-ferrous metal industry

3、  Calcium carbide itself can be used in iron and steel industry of desulfurizer

4、  Under the old miners ore, the calcium carbide will be use to generate in the tin can weave the calcium carbide acetylene (C2H2) into a lamp

Q:What are the types and types of carbide inserts?
There are too many blades, just a few examples of YG3 (used in cast iron, non-ferrous metals and alloys, precision cars or semi fine cars)YT14 (for carbon and alloy steel, semi fine and precision cars)YW1 (applicable to heat resistant steel, high Menggang, stainless steel processing, can also be used for general materials)
Q:What kind of cemented carbide is used for processing HRC40 degrees stainless steel?
It is recommended to choose YS8 welding tool. Very good processing quality can be obtained.
Q:Vacuum sintering of cemented carbide vacuum.
This is not necessarily, the hard alloy sintering infiltration decarburization mainly in wet grinding your ingredients and carbon sintering process control, vacuum furnace gas in order to prevent the reaction of pure, alloy with oxygen in the air, infiltration and decarburization products have no direct relationship, of course if it is caused by the leakage of vacuum sintering furnace can not meet the requirements, will lead to the direction of decarburization alloy.
Q:Is there any pollution in the production of cemented carbide?
The chosen of mask filter is good, also want to close modified ah buy mask anti fog and haze, one can see the standard, can be seen in the two to see that the filtration efficiency standards, should be the most familiar N90, N95 series of mask 3X brand, which is based on NIOSH standard name. In addition to the NIOSH standard, common and ASTM ASTM standard, China standard KN and the European FFP standards, can be used to measure an important indicator of masks, medical masks ordinary cheap, protective also poor, it is only suitable for ordinary nurses or at home cooking; and senior medical masks are surgery the doctor or dentist, the doctor does not care about the higher income, cost is low and the mask, pay more attention to the quality of respirator. The high grade medical mask has excellent barrier to particles and fluids, and ensures breathability and breathability in a precise working environment. Can deodorant ah, city toxic particles source: the first is the automobile exhaust the United States imported medical masks Hiroe server Hin, filter, not only anti particles but also prevent droplets. The particles as small as 0.1 micron filtration efficiency up to 99.8% of bacteria or virus vector as small as 0.3 microns (common in droplet) filtration efficiency is up to 99.9%. Using SecureFit patented technology, through adjustment to adapt to different facial shapes, to achieve high consistency, for your health and family, go out wearing masks, in the J good style East, I wish you happiness, hope to adopt
Q:What industry does carbide belong to? Five
Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.
Q:Buy whole cold carbide drills
Xi'an Jie Electrical Machinery Co., Ltd. internal cooling alloy drill, factory direct sales
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.
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: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:Import all carbide drill bit, mainly those brands
Cobalt collar, YG, Santak, Kenna and so on, YG cost-effective. Used in the high efficiency, high precision, difficult to processing materials, with the overall hard alloy, with cold or cold.
