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:What is hard alloy steel?
- 1, generally called carbide, rather than hard alloy steel.2. Cemented carbides are alloy materials made from hard metal carbides and bonded metals by powder metallurgy process.3, carbide hardness is very high, mainly used for cutting tools.By any means, hard alloy is not the hardest material in the world. Diamond is the hardest material. Many inorganic non-metallic materials have higher hardness than cemented carbides.
- Q:Do you want to center hole? How deep is fit? Or do not hit it directly? My drill bit and the center hole contact point are easy to collapse
- A very shallow point can be;Because once too deep, and the center hole of the aperture is less than the drill bit to drill aperture, so is not in contact with the workpiece, but the main cutting edge part in contact with the workpiece, so cause drill can not correctly centering, so easy to collapse;In the deep hole processing, it is necessary to use pre hole; the general pre hole is the drill bit, the hole size is the same, and the depth is usually about 3 times;I hope I can help you
- 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?
- Too many factors, but according to the shape, size, number and distribution state can be roughly determined what caused by links.
- Q:Will the alloy produced at 400 watts be decarburization or carburizing?
- This is not necessarily, the hard alloy sintering infiltration decarburization mainly in wet grinding your ingredients and carbon sintering process control, vacuum furnace gas in order to prevent the reaction of pure, alloy with oxygen in the air, infiltration and decarburization products have no direct relationship, of course if it is caused by the leakage of vacuum sintering furnace can not meet the requirements, will lead to the direction of decarburization alloy.
- Q:What does carbide K15-K20 refer to?
- Cemented carbide K15, K20General K stands for cemented carbide ISO grades; generally used to process Cast Iron and non-ferrous metals15 represents its abrasion resistance or impact resistance,
- Q:What is the base material of carbide saw blade?
- You can go to Zhuzhou tungsten alloy technology forum to see, detailed description of the carbide saw blade related knowledge, you can go to a lot of professionals with whom to communicate inside.
- 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 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 type of emery grinding machine is 3000/min for grinding carbide turning tools (e.g., YG8.YS8.YT15.YW1, etc.)?
- Green silicon carbide grinding wheel, not sure. You'll have to look at the real map. Some resin grinding wheels are also green.
- 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
