Ntsuab silicon carbide hmoovyog ib qho ntawm feem ntau abrasives ntawm lub khw. Nws yog tsim los ntawm roj av coke thiab zoo silica raws li cov ntaub ntawv tseem ceeb, nrog ntsev ua ib qho ntxiv, thiab smelted ntawm qhov kub thiab txias nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, thiab nws lub zog txhua yam yog siab dua li ntawm corundum.
Ntsuab silicon carbide hmoov tuaj yeem txo qhov tsos ntawm impurities hauv castings. Thaum siv, ntsuab silicon carbide lub zog tuaj yeem txhim kho cov khoom siv kho tshuab, txo qhov tsis xws ntawm cov hlau cam khwb cia, txo tus nqi ntawm cov khoom siv hernia, txo qhov shrinkage kab noj hniav, thiab hloov tag nrho ferrosilicon, yog li ua tiav cov txiaj ntsig kev lag luam zoo dua. Txawm li cas los xij, txhua yam muaj ob sab. Thaum nws zoo, nws kuj muaj qhov tsis zoo, uas yog lub zog ntsuab silicon carbide yuav ua rau muaj kuab paug rau ib puag ncig. Yuav ua li cas muaj kuab paug rau ib puag ncig?
Cov hom tseem ceeb ntawm cov teeb meem hauv cov txheej txheem ntawm silicon carbide yog raws li hauv qab no:
1. Lub teeb muaj kuab paug: Cov txheej txheem tsim khoom yuav tsum tau ignition, uas yog, lub smelting rauv yog hlawv nyob rau hauv qhib cua, thiab muaj hluav taws. Yog tias muaj thaj chaw nyob ze, nws yuav cuam tshuam rau cov neeg nyob hauv lub hnub so. Tab sis nws feem ntau yog huab cua paug. Raws li qhov kev puas tsuaj nyob deb npaum li cas, nws nyob ntawm qhov kev taw qhia cua ntawm lub Hoobkas.
2. Cov pa phem hauv huab cua: plua plav, pa taws, carbon monoxide (me me), carbon dioxide (ib qho loj). Nyob ntawm cov impurities muaj nyob rau hauv cov khoom siv raw, nws kuj tseem muaj sulfur dioxide, nitrogen oxides, thiab lwm yam.
3. Dej muaj kuab paug: feem ntau muaj ntsev ntau. Yog tias muaj cov av ua liaj ua teb thiab cov pas dej nyob ze, thiab lub Hoobkas feem ntau kho cov dej phwj tuaj rau hauv daim ntawv ntawm kev tawm sab nraud, cov pa phem tuaj yeem xav txog.
