Products Description
Centrifugally cast compound steel back -up rolls have a shell of cast steel with alloying elements such as Ni,Cr,Mo.After heat-treatment the roll shell get a fine temper structure, which exhibits good strength and ductility combined with high fatigue properties. When used, the roll shows a high wear and spalling resistance all the time.

- Q:I am 985 material girls graduated, looking for a job, want to know about
- Prospects for the development of hard to say, look at individuals, we this profession, if it is small Shuo, the main income is project bonus, this with your personal ability is very large. These two enterprises are similar in terms of welfare benefits. If you're a girl, it's better to suggest a closer home. Jiangxi copper did not understand, ask your elder sister what, to see if there is no inside, we also find out from these companies in Shixiongshijie there, not just listen to HR talk.
- Q:In addition to diamonds, Hunan there are no good carbide manufacturers? Product advantages in the ordinary blade, knife head and mining tools. Which factory's alloy is of good quality? The best size, with the original tungsten powder. Please know what to say, first thank you
- Looking for packing box manufacturers can find the letter plastic
- 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:Hello, what's your company? What do you do with carbide? Thank you in advance
- Our company is the manufacturer of woodworking knives, made of carbide alloy circular saw blades and forming tools.
- Q:Why carbide fracture?
- Hard alloy is made by casting sintering of tungsten and cobalt, nickel, titanium and tungsten powder, cobalt and nickel matrix, and it is easy to break a bonding metal, quality and technology, process equipment, but also related to the amount of metal content and bonding, in short, hard alloy production is very complex, the quality is strictly, in order to produce good toughness, wear-resistant tungsten is a long-term process of exploration, experiment, a link may not have a good grasp of the products are not qualified.
- Q:One kind of steel is called T10, and another is carbon steel. What kind of hardness and strength do they have?
- Uncertain.Carbon content is different, and some trace elements contain different categories.Alloy steel, which means hardening can harden even when cooled in air, and very sharp. It is a complex alloy steel, containing tungsten, molybdenum, chromium, vanadium and other carbide forming elements. The total amount of alloy elements is about 10 to 25%. It can maintain high hardness at high temperature (about 500 DEG C) in high speed machining, and HRC can be higher than 60.Carbon steel, also called carbon steel, mainly refers to the mechanical properties of carbon depending on the content of steel, and generally do not add a large number of alloy elements of steel, sometimes referred to as general carbon steel or carbon steel. Of iron carbon alloys containing carbon less than 2% WC. Carbon steel, in addition to carbon, usually contains a small amount of silicon, manganese, sulfur and phosphorus.
- Q:What is the difference between them?From hardness, abrasion resistance analysis!
- Is the use of metal carbide hard alloy with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. Its hardness is 93 HRA8, high temperature resistance of 850 ~ 1000 C, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, hard alloy is commonly used tungsten cobalt (YG), tungsten titanium cobalt (YT) and general hard alloy (YW) three.Diamond is an allotrope of carbon, natural diamond and diamond two.
- Q:What are the features of cemented carbide YG8 knives?
- So professional, do not understand the normal, YG8 are used for processing pig iron and other artifacts
- 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.
- Q:Would you like to ask me if the hard alloy can be polished with ordinary metallographic sand paper? Well, what kind of sandpaper does it usually start with? Thank you!
- Another case is that the chemicals in the polishing fluid react with the Co phase in the alloy, causing the Co to overflow or Co to deposit again, so that you need to consider whether you need to replace the polishing fluid.
