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: In addition, the same furnace products out, the standard sample bar is qualified, no hole, but YT14 blade has more holes, why is that ah?
- YT14 alloy you said, if the above holes can start from the following aspects, 1, raw materials, dirty and high oxygen content, impurity content, sintering, 2.If the hole shape of the dirty and dirty, you can see some holes around a circle with cobalt layer, small holes are filled with cobalt, cobalt pool formation, if not pressure, hole like narrow shape.
- Q: Can CBN wheels grind cemented carbide? Why?
- Cubic boron nitride (CBN) grinding wheel is not suitable for grinding carbide and non-metallic hard materials. Cubic boron nitride (CBN) grinding wheel is suitable for processing several material products: high manganese steel; high chromium nickel molybdenum alloy steel; the chilled cast iron (HS80 ~ 90); the various types of hardened steel (HRC55 ~ 65); various types of iron (HB200 ~ 400), and has been in the domestic car (gear, flywheel, shaft, bearing, roller, machining) (slurry pump impeller, volute, shield, sheath and other processing) and mould, the glass cylinder; and the gem high hardness of soft and ductile materials, the high hardness in all walks of life to machining processing of materials, and can enhance the working efficiency. Greatly saves processing time and power and gain huge economic benefits.
- Q: How much does carbide WC contain?
- For example, YG8, tungsten carbide cobalt alloy that represents an average WCo=8% and the rest of tungsten carbideTungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobaltThe grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.
- Q: How can I buy carbide die on the Internet? Who can help?!
- The mould made from the same carbide alloy made from Zhuzhou will not be sold.
- Q: Is the hard alloy the same as the cemented carbide?
- Superhard alloy and cemented carbide are not the same ah.Personally, the alloy feels like a metal of high hardness; for this is not very familiar, there is no right to speak;But the main component of cemented carbide is WC+Co. And some have TIC.TaC. Equal carbide. Basically out of the metal range.So you say cemented carbide and hard metal are different.If it is replaced by superhard materials and cemented carbide to compare. The carbide can be cemented into the superhard material.These are personal views and can be discussed more
- 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: belong to raw material? After buying instockroom directly under the workshop to account for 5The company is small, no warehouse, do not fill in a single storage, the parts purchased directly to use, how to do?It's so complicated. Is there a simple way to do it?
- Carbide grinding head, drill bit, tap, is a tool of low value, easy to wear goods.Welding wire, flux, welding rod and protective welding gas belong to raw material
- Q: Can carbide drills be used for high speed steel twist drills?
- General workpieces do not need alloy drills, although durable, but the cost is too high
- Q: What are the types and types of carbide inserts?
- Your question is really not a simple answer can be got, to see you on what to divide, the blade types according to use classification, can also according to the material classification, and so on, I suggest you go to the official website of Zhuzhou China tungsten alloy has a hard alloy technology knowledge base to see. There's an introduction.
- Q: What blade does the high carbide material use?
- CBN diamond tools, the price is relatively high, high hardness with this basic file, but not the car more than 55 degrees of hardening, if necessary diamond tools contact me. Domestic imports.
