Kev Taw Qhia:

Tungsten hlau, tseem hu ua cemented carbide, yog hais txog cov khoom sib xyaw sintered uas muaj tsawg kawg ib lub hlau carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, thiab tantalum carbide yog cov khoom sib xyaw ntawm tungsten hlau. Qhov loj me ntawm cov khoom carbide (lossis theem) feem ntau yog ntawm 0.2-10 microns, thiab cov carbide nplej raug tuav ua ke siv cov hlau binder. Cov binder feem ntau yog hais txog cov hlau cobalt (Co), tab sis rau qee qhov kev siv tshwj xeeb, nickel (Ni), hlau (Fe), lossis lwm yam hlau thiab alloys kuj tseem siv tau. Kev sib xyaw ua ke ntawm carbide thiab binder theem kom txiav txim siab yog hu ua "qib".

Kev faib tawm ntawm cov hlau tungsten yog ua raws li cov qauv ISO. Kev faib tawm no yog raws li hom khoom siv ntawm cov khoom ua haujlwm (xws li P, M, K, N, S, H qib). Cov khoom sib xyaw ua ke feem ntau yog siv rau nws lub zog thiab kev tiv thaiv corrosion.

Lub matrix ntawm tungsten hlau muaj ob ntu: ib ntu yog theem hardening; lwm ntu yog cov hlau bonding. Cov hlau binder feem ntau yog cov hlau pawg hlau, feem ntau siv cobalt thiab nickel. Yog li ntawd, muaj cov tungsten-cobalt alloys, tungsten-nickel alloys thiab tungsten-titanium-cobalt alloys.

Rau cov hlau uas muaj tungsten, xws li cov hlau ceev ceev thiab qee cov hlau kub ua haujlwm tuag, cov ntsiab lus tungsten hauv cov hlau tuaj yeem txhim kho qhov nyuaj thiab tiv taus cua sov ntawm cov hlau, tab sis qhov tawv yuav poob qis heev.

Daim ntawv thov tseem ceeb ntawm cov peev txheej tungsten kuj yog cemented carbide, uas yog, tungsten steel. Carbide, hu ua cov hniav ntawm kev lag luam niaj hnub, yog siv dav hauv cov khoom tungsten steel.

Cov qauv khoom xyaw

Cov txheej txheem sintering:

Sintering ntawm tungsten hlau yog nias cov hmoov rau hauv ib lub billet, tom qab ntawd nkag mus rau hauv lub cub tawg sintering kom sov rau qee qhov kub (sintering kub), khaws cia rau ib lub sijhawm (tuav lub sijhawm), thiab tom qab ntawd txias nws, kom tau txais cov khoom siv tungsten hlau nrog cov yam ntxwv xav tau.

Plaub theem yooj yim ntawm cov txheej txheem sintering ntawm tungsten steel:

1. Nyob rau theem ntawm kev tshem tawm cov neeg sawv cev tsim thiab ua ntej sintering, lub cev sintered dhau los ntawm cov kev hloov pauv hauv qab no ntawm theem no:

Thaum tshem tawm cov tshuaj molding, nrog rau qhov kub nce ntxiv hauv theem pib ntawm sintering, cov tshuaj molding maj mam decomposes lossis vaporizes, thiab lub cev sintered raug tshem tawm. Hom, ntau npaum li cas thiab cov txheej txheem sintering txawv.

Cov oxides ntawm qhov chaw ntawm cov hmoov raug txo qis. Ntawm qhov kub sintering, hydrogen tuaj yeem txo cov oxides ntawm cobalt thiab tungsten. Yog tias tus neeg sawv cev tsim khoom raug tshem tawm hauv lub tshuab nqus tsev thiab sintered, qhov kev cuam tshuam carbon-oxygen tsis muaj zog. Kev ntxhov siab sib cuag ntawm cov hmoov me me maj mam raug tshem tawm, cov hmoov hlau sib txuas pib rov zoo thiab recrystallize, qhov kev sib kis ntawm qhov chaw pib tshwm sim, thiab lub zog briquetting tau zoo dua.

2. Cov theem sintering khoom (800 ℃ —— eutectic kub)

Ntawm qhov kub ua ntej qhov tshwm sim ntawm cov kua theem, ntxiv rau kev txuas ntxiv cov txheej txheem ntawm theem dhau los, cov tshuaj tiv thaiv theem khov kho thiab kev sib kis tau nce ntxiv, cov yas ntws tau txhim kho, thiab lub cev sintered shrinks tseem ceeb.

3. Theem kua sintering (eutectic kub - sintering kub)

Thaum cov kua theem tshwm sim hauv lub cev sintered, qhov shrinkage tiav sai sai, ua raws li kev hloov pauv crystallographic los tsim cov qauv yooj yim thiab cov qauv ntawm cov hlau alloy.

4. Theem txias (kub sintering - kub chav)

Nyob rau theem no, cov qauv thiab cov khoom sib xyaw ntawm cov hlau tungsten muaj qee qhov kev hloov pauv nrog rau cov xwm txheej txias sib txawv. Qhov no tuaj yeem siv los ua kom sov tungsten hlau kom txhim kho nws cov khoom siv lub cev thiab cov khoom siv kho tshuab.

Kev taw qhia txog daim ntawv thov

Tungsten hlau yog ib feem ntawm cemented carbide, tseem hu ua tungsten-titanium alloy. Qhov nyuaj tuaj yeem ncav cuag 89 ~ 95HRA. Vim li no, cov khoom siv tungsten steel (cov saib xyuas hlau tungsten feem ntau) tsis yooj yim hnav, tawv thiab tsis ntshai annealing, tab sis brittle.
