Taw qhia:

Tungsten steel, tseem hu ua coulented carbide, hais txog carbide, hais txog sintered composite cov ntaub ntawv muaj tsawg kawg ib hlau carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, thiab tantalum carbide yog cov khoom siv ntawm tungsten steel. Cov noob nplej loj ntawm lub carbide tivthaiv (lossis theem) feem ntau ntawm 0.2-10 micrdons, thiab cov nplej carbide nplej tau sib sau ua ke siv cov phau ntawv metallic. Lub binder feem ntau yog hais txog cov hlau cobalt (CO), tab sis rau qee cov ntawv thov tshwj xeeb, Nickel (NE), lossis lwm yam hlau (NEALS thiab alloys kuj tseem siv tau. Kev sib xyaw ua ke ntawm carbide thiab binder theem kom tau txiav txim siab raug xa mus ua "qib".

Kev faib tawm ntawm tungsten steel yog nqa tawm raws li ISO cov qauv. Qhov kev faib tawm no yog raws li cov khoom siv ntawm workpiece (xws li p, m, k, s, h qib ntaus). Lub caij nyoog sib xyaw ua ke yog tsuas yog siv rau nws lub zog thiab corrosion tsis kam.

Matrix ntawm tungsten steel muaj ob ntu: ib feem yog theem ua kom tawv; Lwm qhov yog cov hlau sib txuas lus. Binder cov hlau yog feem ntau cov pab pawg Iron pawg hlau, feem ntau yog siv Cobalt thiab Nickel. Yog li ntawd, muaj tungsten-cobalt alloys, tungsten-nickel alloys thiab tungsten-tungal alloys.

Rau cov hlau uas muaj tungsten, xws li cov hlau ceev thiab qee qhov kub ua haujlwm sib tw ua ke ntawm cov hlau, tab sis cov tawv yuav poob qis.

Lub ntsiab lus tseem ceeb ntawm cov tungsten cov kev pab kuj yog cem carbide, uas yog, tungsten steel. Carbide, hu ua cov hniav ntawm kev lag luam niaj hnub, yog siv dav hauv tungsten steel khoom.

Cov qauv khoom siv khoom xyaw

Sintering txheej txheem:

Sintering ntawm tungsten steel yog kom nias cov hmoov rau hauv lub billet, tom qab ntawd nkag mus rau lub sijhawm (Sinining kub), thiab tom qab ntawd txias nws, yog li tau txais Lub tungsten steel cov khoom nrog cov khoom uas xav tau.

Plaub theem pib ntawm Tungsten Steel Sintering Txheej Txheem:

1. Nyob rau hauv theem ntawm kev tshem cov kev tsim tus neeg sawv cev thiab pre-sintering, cov sintered lub cev undergoes cov kev hloov pauv hauv qab no:

Kev tshem tawm ntawm Moulding tus neeg sawv cev, nrog rau kev nce ntawm qhov kub ntawm cov theem pib ntawm cov decomposes lossis vaporizes, thiab cov sintered lub cev tsis suav nrog. Hom, kom muaj nuj nqis thiab Sintering cov txheej txheem sib txawv.

Cov oxides ntawm cov hmoov ntawm cov hmoov yog txo. Ntawm sintering kub, hydrogen yuav txo cov oxides ntawm cobalt thiab tungsten. Yog tias tus neeg sawv cev sib zog tau raug tshem tawm hauv lub tshuab nqus tsev thiab sintered, cov pa roj oxygen tsis muaj zog. Kev sib tiv tauj kev ntxhov siab ntawm cov hmoov xau yog maj mam tshem tawm, cov hmoov hlau sib txawv pib, thiab lub briquetting lub zog yog ntxiv.

2. Khoom theem Sintering theem (800 ℃ --EUECTECTICE)

Ntawm qhov kub ua ntej cov tsos ntawm cov kua dej, ntxiv rau txuas ntxiv cov txheej txheem ntawm cov kev sib cais dhau los, cov roj hmab txaus yog txhim kho, thiab cov sintered lub cev shrinks.

3. Kua Theem Sintering Theem (Eutectic Kub - Sinining Kub)

Thaum cov theem ua kua tshwm nyob rau hauv lub cev, cov shrinkage tiav, ua raws li kev hloov pauv crystallogration los ua tus qauv yooj yim thiab qauv ntawm cov alloy.

4. Txias theem (sinining kub - chav sov)

Nyob rau theem no, tus qauv thiab theem muaj pes tsawg leeg ntawm tungsten steel muaj qee qhov kev hloov pauv nrog cov xwm txheej txias. Cov yam ntxwv no tuaj yeem siv los ua kom sov-trench tungsten steel txhawm rau txhim kho nws lub cev thiab cov kws kho tshuab.

Daim Ntawv Thov Kev Taw Qhia

Tungsten Steel belong belongs kom cemented carbide, kuj hu ua tungsten-titanium alloy. Lub hardness tuaj yeem ncav cuag 89 ~ 95hra. Vim tias qhov no, tungsten steel khoom (ib txwm tungsten steel watches) tsis yooj yim rau hnav, nyuaj thiab tsis ntshai ntawm annealing, tab sis nkig.

Lub Cheebtsam tseem ceeb ntawm cov tsoosed carbide yog tungsten carbide thiab cobalt, uas yog lwm yam khoom siv, yog li nws tseem yog hu ua tungsten steel.

Feem ntau siv nyob rau hauv high-precision machining, siab-precision tuam khoom, lathes laum khoom, nyuaj thiab tsis ntshai analing, tab sis nkig. Belongs rau cov hlau tsis tshua muaj.

Tungsten steel (tungsten carbide) muaj cov khoom muaj txiaj ntsig zoo xws li kev ua kom muaj zog, tshwj xeeb yog qhov kev ua kom zoo thiab hnav tsis kam, txawm tias ntawm qhov kub ntawm 500 ℃. Nws nyob twj ywm tsis hloov pauv, thiab tseem muaj lub siab tawv ntawm 1000 ° C.
