Nrog rau kev txhim kho kev lag luam,dub silicon carbide yog siv ua ib qho khoom ntxiv rau hauv ntau yam lag luam thiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom zoo thiab cov txheej txheem tsim khoom. Kev lag luam foundry tau dhau los ua ib yam khoom tseem ceeb hauv kev lag luam niaj hnub no. Black silicon carbide tau ua lub luag haujlwm tseem ceeb hauv kev lag luam no. Nrog rau kev hloov pauv ntawm thev naus laus zis, nws tau nyiam ntau tus neeg lub siab.
Lub luag haujlwm ntawm cov dub silicon carbide ua ib qho khoom ntxiv:
Kev ua tau zoo ntawm cov cua sov thiab kev ruaj khov ntawm cov cua sov, siv ua lub tshuab hloov pauv cua sov, txo kev siv roj los ntawm 20%, txuag roj los ntawm 35%, ua rau muaj kev tsim khoom ntau ntxiv los ntawm 20-30%, tshwj xeeb tshaj yog rau cov kav dej tawm hauv tsev thiab cov kav dej thauj mus los ntawm cov chaw cog khoom siv hauv av, tiv taus cov roj silicon dub Qhov kev sib tsoo yog 6 txog 7 npaug ntawm cov khoom siv tiv taus kev hnav dav dav.
Kev siv cov silicon carbide dub muaj kev tiv taus kub siab, muaj zog siab, ua kom muaj cua sov zoo heev, tiv taus kev cuam tshuam, thiab siv tau ua cov khoom siv cua sov ncaj qha rau qhov kub siab, xws li cov cub tawg hauv lub lauj kaub nyuaj, cov tais rau cub tawg, cov hlwb electrolytic txhuas, cov ntaub thaiv cua sov tooj liab, thiab cov cub tawg hmoov zinc. Arc phaj, thermocouple txij nkawm raj, thiab lwm yam. Kev siv cov hlau, tiv taus corrosion, tiv taus thermal shock thiab hnav tsis kam, cov yam ntxwv zoo ntawm kev ua kom sov, siv rau cov ntaub thaiv cua sov loj txhim kho lub neej kev pabcuam.
Lub luag haujlwm ntawm cov dub silicon carbide:
Kev siv cov silicon carbide dub pab tau zoo rau kev txhim kho cov khoom zoo, vim tias silicon carbide tuaj yeem ua rau kom muaj kev sib xyaw ua ke zoo, ua kom cov hlau yaj ruaj khov, thiab zam kev sib cais. Qhov no tuaj yeem txo qhov rhiab heev ntawm phab ntsa, ua rau cov qauv ntom thiab qhov chaw txiav ci.
Cov roj silicon dubtuaj yeem ua rau kom muaj peev xwm nucleation ntawm casting graphite, zoo thiab tseem ceeb txhim kho qhov kev siv tshuab ntawm castings, txhim kho cov khoom siv kho tshuab, thiab rau silicon carbide, nws tuaj yeem zam kev sib cais ntawm carbides, nce qhov ntau ntawm ferrite, thiab txo qhov dawb tsos.
Cov silicon carbide dub kuj tseem tuaj yeem ua rau muaj zog deoxidizer, uas tuaj yeem ntxuav cov hlau molten, txo cov nodulizer ntxiv, thiab txhim kho tus nqi nodularization, uas yog qhov pab tau zoo hauv kev txuag cov nqi tsim khoom.
