Silicon carbide ceramics: kev hloov pauv hauvcov khoom siv uas tsis yooj yim hnavrau kev lag luam mining
Kev lag luam khawb av yog lub npe nrov rau nws txoj kev ua haujlwm hnyav, tshwj xeeb tshaj yog nyob rau hauv thaj chaw ntxuav khawb av, qhov twg cov khoom siv feem ntau raug rau cov khoom siv abrasive. Nyob rau hauv ib puag ncig uas nyuaj heev, qhov xav tau cov khoom siv uas tsis yooj yim hnav yog qhov tseem ceeb heev. Qhov no yog qhov uas kev siv silicon carbide ceramics los ua si, muab cov kev daws teeb meem hloov pauv rau kev lag luam khawb av.
Vim lawv qhov tawv thiab hnav tsis kam, silicon carbide ceramics tau dhau los ua cov khoom siv zoo tshaj plaws rau ntau yam khoom siv hauv kev ua haujlwm mining. Hauv kev lag luam ua cov hlau metallurgy, silicon carbide ceramics siv dav hauv impellers, chav twj tso kua mis, cov kav dej tiv taus hnav, cyclones, hopper linings, thiab lwm yam. Lawv muaj kev tiv taus hnav zoo heev, 5-20 npaug ntawm roj hmab thiab hlau cam khwb cia, ua rau lawv tsis tseem ceeb rau kev tiv taus kev sib txhuam ntawm cov txheej txheem ntxuav mining.
Cov yam ntxwv tshwj xeeb ntawm cov khoom siv silicon carbide ua rau lawv zoo tagnrho rau kev lag luam mining. Lawv qhov nyuaj tshwj xeeb, thib ob tsuas yog pob zeb diamond, ua kom ntseeg tau tias lawv tuaj yeem tiv taus cov xwm txheej nyuaj uas tshwm sim hauv kev ua haujlwm mining. Qhov nyuaj no ua ke nrog kev tiv thaiv kev hnav zoo ua rau nws zoo tagnrho rau cov khoom uas raug hnav thiab tawg tas li.
Tsis tas li ntawd xwb, qhov kev tiv taus hnav ntawm cov khoom siv silicon carbide ceramics ua rau lawv lub neej ua haujlwm ntev dua thiab txo qhov zaus ntawm kev hloov pauv thiab kev saib xyuas, yog li pab txuag cov nqi hauv kev ua haujlwm hauv kev khawb av. Qhov kev ruaj khov thiab lub neej ntev no ua rau lawv yog qhov kev daws teeb meem pheej yig rau kev lag luam khawb av, qhov twg kev ntseeg siab thiab kev ua tau zoo ntawm cov khoom siv yog qhov tseem ceeb.
Tsis tas li ntawd xwb, cov kev siv silicon carbide ceramics tsis yog tsuas yog rau kev lag luam mining xwb. Lawv cov yam ntxwv zoo heev kuj ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev tsav dav hlau, tshwj xeeb tshaj yog hauv kev tsim kho txoj kev khiav dav hlau, qhov twg lawv qhov kev tiv taus hnav thiab kev ruaj khov yog qhov tseem ceeb heev.
Hauv kev xaus lus, kev siv cov khoom siv silicon carbide ceramics hauv kev lag luam mining tau hloov pauv txoj kev tsim cov khoom siv uas tsis yooj yim hnav. Nws qhov nyuaj tshwj xeeb, kev tiv taus hnav zoo thiab kev siv nyiaj tsim nyog ua rau nws yog qhov kev xaiv tseem ceeb rau cov khoom siv hauv kev ntxuav mining thiab lwm yam kev ua haujlwm mining. Thaum kev lag luam mining txuas ntxiv hloov pauv, silicon carbide ceramics yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm cov khoom siv thiab lub neej ua haujlwm, thaum kawg pab txhawb rau kev ua haujlwm zoo thiab kev ruaj khov ntawm kev ua haujlwm mining.
