Yuav siv silicon carbide crucible li cas rau kev ntxuav hlau?

Qhov laj thawj yog vim li cassilicon carbide cruciblemuaj txiaj ntsig zoo rau kev siv vim nws cov khoom siv sib xws. Silicon carbide muajcov khoom siv tshuaj ruaj khov, kev ua tau zoo ntawm cov cua sov, coefficient ntawm kev nthuav dav thermal qisthiab zoo hnav tsis kam. Ntxiv rau kev siv ua abrasive, nws kuj muaj ntau lwm yam kev siv. Piv txwv li, txheej silicon carbide hmoov rau ntawm phab ntsa sab hauv ntawm turbine impeller lossis lub tog raj kheej thaiv nrog cov txheej txheem tshwj xeeb tuaj yeem txhim kho nws txoj kev hnav tsis kam thiab ntev nws lub neej kev pabcuam los ntawm 1 ~ 2 zaug; Cov khoom siv hluav taws kub zoo ua los ntawm nws muaj qhov zoo ntawmkev tiv thaiv kub hnyiab, me me,lub teeb yuag, muaj zog heev thiab txuag hluav taws xob zoo. Cov silicon carbide qib qis (muaj li ntawm 85% SiC) yog ib qho deoxidizer zoo heev. Nws tuaj yeem ua kom ceev nrooj ntawm kev ua hlau, pab tswj cov tshuaj lom neeg thiab txhim kho qhov zoo ntawm cov hlau.
Hauv daim ntawv thov ntawm silicon carbide crucible, lub luag haujlwm ntawm kev ua haujlwm hlau thiab kev ntxuav tau lees paub los ntawm cov neeg siv. Hauv kev lag luam daim ntawv thov crucible, qhov chaw ntawm silicon carbide crucible tuaj yeem hais tias yog qhov tseem ceeb.
Vim tias silicon carbide yog ua los ntawmxuab zeb quartz, roj av coke, sawdust thiab lwm yam ntaub ntawv los ntawm kev ua haujlwm kub siab hauv lub cub tawg tiv taus, lub silicon carbide crucible muaj zogtiv taus hluav tawsmuaj peev xwm ua cov haujlwm ua hlau, yog li nws txaus kom ntseeg tau tias qhov kub siab xav tau rau kev tawm dag zog, txo qhov nyuaj ntawm kev ua kom cov hlau zoo, txuag nqi thiab txhim kho kev siv tau zoo.
