Kev tsim cov tungsten Carbide hmoov

Tungsten carbide hmoov yog cov khoom siv tseem ceeb los tsim cov khoom tungsten carbide. Qee yam tuaj yeem yuav tungsten carbide hmoov ncaj qha, thiab qee qhov yuav rov ua dua los ntawm lwm tus. Tungsten carbide hmoov tsis pom ncaj qha hauv qhov xwm txheej. Lawv yog tsim los ntawm ib tug series ntawm cov txheej txheem. Hauv tsab xov xwm no, kev tsim cov tungsten carbide hmoov yuav yog cov lus qhia luv luv.

Ntau lawm

Tungsten carbide muaj qhov sib npaug ntawm tungsten thiab carbon. Txhawm rau tsim tungsten carbide, tungsten trioxide yuav tsum tau hydrogenated thiab txo ua ntej. Hauv cov txheej txheem no, peb tuaj yeem tau tungsten hmoov thiab kua dej. Tom qab ntawd cov hmoov tungsten thiab cov pa roj carbon yuav raug nias rau sab nraud ntawm qhov sib npaug mole piv. Lub block pressed yuav muab tso rau ntawm graphite lauj kaub thiab rhuab mus rau ntau tshaj 1400 ℃ nyob rau hauv ib tug induction rauv nrog ib tug hydrogen kwj. Nrog rau qhov nce ntawm qhov kub thiab txias, 2 moles ntawm tungsten yuav hnov ​​​​mob nrog 1mole ntawm carbon thiab tsim cov W2C. Thiab tom qab ntawd qhov sib npaug tungsten thiab carbon yuav hnov ​​​​mob thiab tungsten carbide yuav raug tsim. Cov tshuaj tiv thaiv yav dhau los tshwm sim ua ntej tshaj qhov tom kawg vim tias qhov kub thiab txias rau yav dhau los cov tshuaj tiv thaiv qis dua. Lub sijhawm no, muaj ntau tshaj W, W2C, thiab WC uas twb muaj lawm nyob rau hauv qhov cub. Lawv yuav hnov ​​​​mob hauv qhov kub thiab txias. Tom qab cov txheej txheem tiav lawm, peb tuaj yeem tau txais tungsten carbide hmoov.

Lub ntsiab tshuaj tiv thaiv yog raws li nram no:

WO3 + 3H2 → W + 3H2O

2W + C = W2C

W + C = WC

Cia

tungsten carbide hmoov yog zoo dua rau khaws cia rau hauv lub tshuab nqus tsev ntim khoom thiab khaws cia hauv chav txias thiab qhuav.

Daim ntawv thov

tungsten carbide hmoov yog siv los ua cov khoom lag luam tungsten carbide. tungsten carbide hmoov, tov nrog ib qho kev faib ua feem ntawm cov binders yuav zoo li tus thiab sintered rau hauv txawv tungsten carbide khoom yuav tsum tau siv nyob rau hauv ntau daim ntawv thov. Tungsten carbide hmoov tuaj yeem ua rau hauv tungsten carbide nyees khawm rau kev siv tsuas, tungsten carbide studs rau HPGR, tungsten carbide rods rau manufacturing kawg mills, thiab tungsten carbide burr txiav thiab zeb lwm yam ntaub ntawv.

Los ntawm tsab xov xwm no, peb tuaj yeem paub txog kev tsim cov tungsten carbide hmoov, uas yog cov khoom siv raw ntawm ntau cov khoom siv tungsten carbide thiab tungsten alloys. Yog li tsim nyog khaws cia tungsten carbide hmoov yog qhov tseem ceeb los xyuas kom meej tias cov khoom tungsten carbide tuaj yeem khaws lawv cov kev ua tau zoo.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
