Silicon carbide ceramics: lub kiv puag ncig ntawm qhov hnav-tiv taus rau kev lag luam mining

Silicon carbide ceramics: lub kiv puag ncig hauvhnav-resistant qhov chawrau kev lag luam mining

Kev lag luam mining paub txog nws cov kev ua haujlwm nruj, tshwj xeeb tshaj yog nyob rau hauv lub mining ntxhua khaub ncaws, qhov chaw uas cov khoom siv tsis tu ncua raug rau cov khoom siv abrasive. Hauv qhov xav tau ib puag ncig zoo li no, qhov xav tau ntawm qhov hnav-tiv taus yog qhov tseem ceeb. Qhov no yog qhov uas daim ntawv thov ntawm silicon carbide ceramics los rau hauv kev ua si, muab kev ua si hloov kev daws teeb meem rau kev lag luam mining.

Silicon carbide ceramics tau dhau los ua cov khoom siv zoo tshaj plaws rau ntau yam khoom siv hauv kev lag luam mining vim lawv cov hardness zoo heev thiab muaj zog hnav tsis kam. Hauv kev lag luam metallurgical ntxhia ua kev lag luam, silicon carbide ceramics tau dav siv hauv impellers, twj tso kua mis, cov kav dej hnav tsis zoo, cyclones, hopper linings, thiab lwm yam. indispensable rau withstanding abrasiveness ntawm mining ntxuav txheej txheem.

Cov khoom tshwj xeeb ntawm silicon carbide ceramics ua rau lawv zoo tagnrho rau kev lag luam mining. Lawv qhov tshwj xeeb hardness, thib ob tsuas yog pob zeb diamond, ua kom ntseeg tau tias lawv tuaj yeem tiv taus qhov hnyav hnyav hauv kev ua haujlwm tsuas. Qhov hardness no ua ke nrog muaj zog hnav tsis kam ua rau nws zoo tagnrho rau cov khoom siv tsis tu ncua thiab yaig.

Tsis tas li ntawd, qhov hnav tsis kam ntawm silicon carbide ceramics txuas ntxiv lawv lub neej kev pab cuam thiab txo qhov zaus ntawm kev hloov thiab txij nkawm, yog li pab txuag nqi hauv kev ua haujlwm tsuas. Qhov kev ua haujlwm ntev thiab kev ua haujlwm ntev no ua rau lawv muaj txiaj ntsig zoo rau kev lag luam mining, qhov twg cov khoom siv kev ntseeg siab thiab kev ua tau zoo yog qhov tseem ceeb.

Tsis tas li ntawd, kev siv ntawm silicon carbide ceramics tsis txwv rau kev lag luam mining. Lawv cov khoom zoo heev kuj ua rau lawv yog cov khoom siv zoo tshaj plaws rau kev siv dav hlau, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho, qhov twg lawv hnav tsis kam thiab ua haujlwm tau zoo heev.

Hauv cov ntsiab lus, kev siv cov silicon carbide ceramics hauv kev lag luam mining tau hloov pauv kev tsim cov khoom hnav-tiv taus. Nws tshwj xeeb hardness, muaj zog hnav tsis kam thiab tus nqi-zoo ua rau nws yog ib qho kev xaiv tsis tseem ceeb rau cov khoom siv hauv mining ntxhua thiab lwm yam kev lag luam mining. Raws li kev lag luam mining txuas ntxiv mus, silicon carbide ceramics yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov cuab yeej ua haujlwm thiab kev pabcuam lub neej, thaum kawg pab txhawb rau tag nrho cov txiaj ntsig thiab kev ruaj khov ntawm kev ua haujlwm tsuas.
