Q:Printing requirements for cemented carbide

Its disadvantages are: there are a small amount of pores and defects in the product, and the carbon content of the sinter will decrease.Hot isostatic pressing sintering in sintering with inert gas, liquid metal or solid particles as pressure transfer medium in each direction of the sintered body exert equal pressure, not even this can overcome ordinary hot pressing pressure is not uniform and the resulting product performance. The hot isostatic pressing of cemented carbide can eliminate the pores in the alloy and the drilling pool after sintering, and restrain the growth of WC grain. The Kennametal Inc installed the first heating chamber for 277mm * 1270mm in 1967. The temperature is up to 1500oC and the pressure can reach140MPa's hot isostatic pressing machine has taken the lead in successfully applying the technology of hot isostatic pressing to the production of cemented carbide. Since then, hot isostatic pressing technology has developed rapidly in foreign countries (especially in the United States).

Q:Hello, what's your company? What do you do with carbide? Thank you in advance

Pro, what do you mean by that question? We are the hard alloy recycling companies, focus on hard alloy recovery, Qingdao cemented carbide business network, with the recovery of hard alloy scrap, hard alloy die, tungsten steel scrap recycling

Q:MIG and TIG welding of cobalt base carbide and medium low carbon steel, respectively, using copper wire and stainless steel wire. What kind of corrosive liquid should be used in the welding seam to be metallographic?MIG+ copper welding wire, MIG+ stainless steel wire, TIG+ stainless steel wire

Cobalt based alloy is a cemented carbide that is capable of various types of wear and corrosion as well as high temperature oxidation. Commonly known as the cobalt chromium tungsten (molybdenum) alloy or Si Taili (Stellite) alloy (Si Taili alloy invented by the American Elwood Hayness in 1907).

Q:What does P stand for and what is 30? What are its advantages and disadvantages? What is suitable for processing?

1.p stands for ferrous metals suitable for working long cuts.2.p30 is suitable for working steel, cast steel, long cut malleable iron. Suitable for general rough machining.

Q:What materials are hard alloys used to process?

YG hard alloy, impact resistance, high temperature resistant, processing pig iron.

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:What does WC refer to in cemented carbides?

Of or relating to an alloying element that is tungsten carbide.Tungsten cobalt carbideThe main ingredients are 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, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.

Q:What kind of clamp blade should be used for hard alloy?

As long as the diamond can move the hard alloy, well go to China tungsten carbide technology network learning it!

Q:Carbon steel valves in Baidu LibraryThe temperature can reach 425 degrees, is not without welding carbide seal, who has no detailed material ah?,

The 425 degree here means that WCB carbon steel can withstand such high temperatures and has little to do with sealing. In the sealing surface location, surfacing, etc., is the role of erosion resistance. If your body can only withstand 200 degrees, but your valve that can withstand 1000 degrees, which makes sense? So resistance to temperature is a comprehensive concept, and the temperature depends on the lowest temperature resistance in all of your parts (somewhat similar to the cask theory in economics). Of course, scouring will be a little faster at high temperatures.

Q:Hard alloy and cast iron join together, use temperature 150 degrees, what glue is better to use?

High temperature resistant high strength metal and carbide inorganic adhesive YL04-3. For the structure of all kinds of cutting tools such as bonded &def hard alloy cutter and lengthened drill, geological drill; casting airhole crack repair; use temperature of -196 DEG ~800 DEG
