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 cemented carbide does 2gr13 use?: 2Cr13 martensitic stainless steel can be processed by hard alloy YW2, carbide YW2 suitable for heat-resistant steel, high manganese steel, stainless steel and advanced alloy steel and other special difficult to processing steel finishing, semi finishing.

Q:What type of carbide is the most ductile?: Cemented carbide material with tungsten and cobalt carbide toughness is better, at present the carbide grade in the most toughness of YG15. The relation between cobalt content and toughness is shown below. It can be seen that cobalt content and 13%-16% toughness are the best. In this interval, only YG15 cobalt content is 15%.

Q:Carbide grades, properties and applicable ranges: The commonly used cemented carbides are mainly based on WC, and are classified into the following categories whether or not they are added to other carbides:(1) tungsten cobalt (WC+Co) cemented carbide (YG);It consists of WC and Co which has higher flexural strength, toughness, good thermal conductivity, but heat resistance and poor wear resistance, mainly used for processing cast iron and nonferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, the hardness, wear resistance than YG3 YG6 high strength and toughness is poor, suitable for machining hard cast iron, austenitic stainless steel, heat-resistant alloy, hard bronze.

Q:We'll drill on the stainless steel column. Which bit is better?: High cutting force and high cutting temperatureThis kind of material has high strength, large tangential stress and large plastic deformation during cutting, so it has great cutting force. In addition, the material has a poor thermal conductivity, which results in the increase of cutting temperature, and the high temperature often concentrates in the long and narrow area near the cutting edge of the tool, thus speeding up the tool wear.Serious work hardeningAustenitic stainless steel and some high alloy stainless steel is austenite, high work hardening tendency when cutting, usually plain carbon steel several times, the tool in hardening region cutting, shortening tool life.Easy to stick the knifeBoth austenitic stainless steel and martensitic stainless steel exist in the process of chip toughness, cutting temperature is very high. When the tough chip flows through the rake face, the bonding, welding and other sticking phenomena will occur, which will affect the surface roughness of the machined parts. ??Tool wear acceleratedThe materials generally contain high melting point elements, large plasticity, high cutting temperature, so that the tool wear faster, sharpening and changing knives frequently, thus affecting the production efficiency and improving the tool cost.Mainly to reduce the cutting line speed, feed. With special processing stainless steel or high temperature alloy cutting tools, drilling, tapping the best internal cooling

Q:Carbide coated drill bit will reduce the service life after grinding, how to avoid?: Hello, there is no way to avoid the problem of reducing the service life of the carbide coated drill bit after grinding;Cemented carbide bit, in its use, the surface coating, the blade has already been damaged, can not reach the integrity of the factory, so that it affects the service life of the drill bit,There is a need to be re grinding, coating, the coating has physical and chemical coating and coating, coating chemical now use more chemical coating basically is the tool coating at high temperature, so the temperature can cause 2 damage of cemented carbide substrate;So it also affects the service life;The effect of bit life, the most important is the geometric design of drill bit; before the design is not good, but when re grinding and grinding a good point, sometimes improve the service life, but the original drill must use will reduce the life of the;About those problems mentioned above, in fact, that is, some methods to improve the service life of the drill, upstairs can refer to

Q:I would like to use carbide cutting tools, car work, ordinary A3 steel or 45 steel, lathe speed to play more appropriate, the workpiece surface quality is better?: My car operation for more than 8 years, according to your car parts, actually hit 600 on the coarse, fine car or 1600 rpm, finish good, cutting speed is not too fast, the general lathe is mid-range open 6 can, keep your car parts after.

Q:Processing stainless steel 301 milling thickness of about 3 millimeters, with what blade good?: You mainly milling the surface is not refined, there is no need to use that good, in one is YS25, cheap, well, that's it, if there is any good advice to my replies

Q:the blade is hard alloy, the processing material is QT600, the plane lower tool margin is 4mm, the speed and the knife: This belongs to the category of ductile iron, more difficult to process, because the material is hard particles, it is recommended around S=1200 F=400

Q:The difference between carbide knife and white steel knife: 3, hardness is not the same: cemented carbide hardness, especially at high temperature hardness, but high-speed steel toughness better4, can withstand the cutting speed is not the same: due to the red hard high, can withstand higher cutting speed, and high-speed steel is now not high speed

Q:What is the tungsten alloy blade, what is the difference with the hard alloy blade? What is it for?: Tungsten alloy blade is a kind of hard alloy, metal processing used in the workpiece.
