Low Carbon Ferro Chrome Hot Sale Chinese Cargo

Product Description

Chrome is always used to improve the antioxidation and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhension oxide film. Then it stops being oxidized or decelerates being oxidized.Micro-Carbon ferro chorme is applied to making stainless, acid-resistant steel and heat resistant steel.

Q: What kind of carbide alloy is used in stainless steel processing?: Such as: YA6; YH1; YW3. This kind of steel has high hardness, small amount of feed to lower cutting speed, cutting the depth is bigger, avoid hardening layer on the surface of the skin with the previous procedure (Note 2).

Q: Carbide die how to calculate weight, that is to say, its kg weight: Cemented carbide die weight = volume * density, tungsten cobalt carbide, density 14.4~15.3, cobalt content is higher, the lower the density.

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 are the cemented carbide coatings?: The hard alloy coating is used to form high hardness wear-resistant coating on the surface of metal, Beijing Naimo company according to the composition of the alloy is divided into:1.jp8000 spraying tungsten carbide coating2. nickel tungsten alloy coating3. cobalt tungsten alloy coating

Q: Carbide saw blade 30t and 40t what is the difference?: The more the number of teeth, the more smooth the cut section is. If your machine is stable, the sound will be smaller

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: How are cemented carbides separated from the cutting tools?: Tools are usually brazed by high-frequency induction:The blade part on the induction coil, through high frequency alternating current induction electromagnetic field, the induced electromotive force generated in the workpiece surface coupling, forming eddy current on the metal surface by eddy current heat generated in the metal surface, the welding parts usually coated with solder powder, welding can be reached until the melting temperature of workpiece. Take off the blade, too.

Q: What are the carbide inserts on the turning tool welded to the handle?: The common oxygen welding and brazing flux borax and welding line! The welding method is as follows: when welding, first use four carbon chloride (CCl4) to wash the welding section of the knife pole, and then use the oxygen and acetylene to turn the tool red and then sprinkle borax! Melt the copper into the top of the knife. Place the blade on the knife and continue to burn until the copper and alloy blades come in contact. An ordinary soldering knife comes out.

Q: What are the types and types of carbide inserts?: According to the size of the grain, it can be divided into ordinary cemented carbide, fine grain cemented carbide, sub fine and ultra-fine grain cemented carbide, and newly introduced twin cemented carbide. Model manufacturers are different, different models.Carbide inserts are made of hard alloy, an alloy made from refractory metals, hard compounds, and bonded metals by powder metallurgy.

Q: What are hard alloys? Which ones are they? How often are they chosen?: 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.
