WC khoom tsim nyog
Cov sib txawv ntawm cov carbide siv ntau qhov ntau ntawm WC (tungsten carbide). Kev siv cov cuab yeej ua haujlwm xws li tshuab txiav txiav, V-CUT riam thiab lwm cov khoom siv xov zoo siv ultra-fine, sub-fine, fine-grained WC, cov ua haujlwm txuam nrog cov thev naus laus zis WC, siv nruab nrab thiab tuab Particle WC yog siv raw khoom; cov cuab yeej mining: cov pob zeb loj zog, kev cuam tshuam loj heev, ntxhib particle WC, cov pob zeb me me thiab kev cuam tshuam me me. Medium particle WC yog siv ua raw khoom; Cov cuab yeej siv rau sab cev nqaij daim tawv: Thaum nws ua kom nws tsis hnyav, ua kom tsis muaj zog thiab ua kom tiav nto Thaum siv ultra-fine, nplua zoo, nplua, medium-grain WC li raw cov ntaub ntawv, cov cuab yeej-feem ntau yog cov nruab nrab thiab coarse-grain WC ny cov ntaub ntawv.
WC theoretical carbon cov ntsiab lus yog 6.128% (atomic 50%). Thaum cov ntsiab lus ntawm WC cov pa roj carbon dioxide ntau dua li cov ntsiab lus carbon theoretical, dawb carbon (WC + C) tshwm hauv WC. Qhov muaj cov kab mob dawb ua rau thaj tsam WC cog qoob loo kom loj hlob thaum lub sij hawm sintering, ua rau tsis muaj carbide nplej. Tungsten carbide feem ntau yuav tsum muaj cov pa roj carbon monoxide (≥6.07%), dawb carbon (≤0.05%), thiab tag nrho cov roj yog txiav txim siab los ntawm cov txheej txheem ntau thiab cov kev siv cov cemented carbide.
Tam sim no, tag nrho cov ntsiab lus ntawm cov dej hauv WC hauv Suav teb tau muab faib ua 3 hom: tag nrho cov dej ntawm WC rau lub tshuab nqus tsev sintering ntawm tus txheej txheem paraffin yog li 6.18 ± 0.03% (dawb carbon yuav nce). Tag nrho cov ntsiab lus ntawm WC rau hydrogen sintering hauv cov txheej txheem paraffin yog 6.13 ± 0.03%. Tag nrho cov dej ntawm WC rau roj hmab txheej txheem hydrogen sintering yog 5.90 ± 0.03%. Cov txheej txheem saum toj saud qee zaum nkag mus, yog li nws tau txiav txim siab tias tag nrho cov dej ntawm WC yog qhov teeb meem.
Cov WC tag nrho cov roj siv hauv cov phom leej ntau hom kev siv, ntau cov Co (cobalt) thiab cov qoob loo sib txawv txawv tau kho me ntsis. Rau cov ua kom tsis txhob muaj cov kab mob qaub ncaug, tungsten carbide nrog lub siab tag nrho cov roj, thiab rau cov roj coconut, tungsten carbide nrog cov roj tsawg tsawg. Hauv ntej, kev siv cov kev cai ntawm cov cemented carbides muaj kev txwv ntawm cov khoom me me ntawm tungsten carbide. Thaum koj muaj qhov tshwj xeeb raws li qhov tshwj xeeb rau lub tungsten carbide paper riam, thov qhia rau peb thaum koj xa duab. Ua tsaug ntau!
