Steelmaking deoxidizer are mainly silicon aluminum barium calcium iron, silicon calcium packets wire, aluminum wire, aluminum ferromanganese, aluminium, calcium carbide and silicon carbide, etc., main effect is reaction with oxygen dissolved in molten iron, non-metallic compounds, mainly generated form precipitation floatation to slag layer, and then remove can be pure molten iron.

Main way of DNA have precipitated DNA, diffusion deoxidation and vacuum deoxidation, etc. In modern steelmaking the vacuum equipment can also be used to DNA, such as VD furnace, VOD furnace, etc.

Q:What is the difference between the production process of ferrous powder metallurgy and cemented carbide?
In 1890, the invention of tungsten powder, made by powder metallurgy, in the United States, laid the foundation of modern powder metallurgy. Around 1910, it has been made by powder metallurgy method of tungsten and molybdenum products, hard alloy, bronze bearings, porous filters, brush set, and gradually formed a complete set of powder metallurgy technology. In 1930s, after the advent of the vortex grinding iron powder and the carbon reduced iron powder, the iron based mechanical parts made by powder metallurgy have gained rapid development.
Q:What kind of cemented carbide is used for processing HRC40 degrees stainless steel?
This kind of hardness stainless steel is martensite, hardness is high, use tungsten cobalt class (do not use tungsten, cobalt, titanium, this is attention 1), and carbide containing Ta. Such as: YA6, YH1, YW3, etc.. This kind of steel is of high hardness, small feed rate, lower cutting speed, greater cutting depth, and avoiding the work hardening of the surface leather and the front working procedure (Notice 2). Machine tools. The steel of the tool is better. The coolant selects viscous and chlorine - containing cooling liquid with good adhesion and cooling performance. (Note 3)
Q:Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?
The main component of the tungsten steel milling cutter in cemented carbide is tungsten carbide, tungsten steel on steel hardness and heat resistance are significantly improved, but the toughness decreased sharply.
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:What is the hardness of the carbide thread?
The hardness of cemented carbide tools is generally between 89~92.8, such as the hardness of YG8 is HRA89, the hardness of YT30 is 92.8, and the hardness of YT15 is 91.
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:The difference between HSS and carbide knives
High speed steel which is mainly used in the rapid operation of the machine, its good fatigue performance, high temperature performance is better, but the hardness is generally hard alloy steel mainly refers to alloy steel with high hardness, high hardness of the steel is mainly emphasized in a certain range, but may be brittle or will be relatively large, high performance high temperature, poor.
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: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:What materials are ZK20 cemented carbides processed?
ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic
