Yuav ua li cas siv silicon carbide crucible rau hlau purification?

Yog vim li cassilicon carbide cruciblemuaj zog siv tswv yim nqi yog vim nws cov khoom siv. Silicon carbide muajruaj khov chemical zog, siab thermal conductivity, Tsawg thermal expansion coefficientthiab zoo hnav tsis kam. Ntxiv nrog rau kev siv ua abrasive, nws kuj muaj ntau 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 cov hnav tsis kam thiab ua kom nws lub neej ua haujlwm ntev li 1 ~ 2 zaug; Cov khoom siv hluav taws kub-qib siab ua los ntawm nws muaj qhov zoo ntawmkub poob tsis kam, ntim me me,lub teeb nyhav, siab zog thiab zoo zog-txuag nyhuv. Qib qis silicon carbide (muaj txog 85% SiC) yog ib qho zoo heev deoxidizer. Nws tuaj yeem ua kom nrawm nrawm ntawm steelmaking, pab tswj cov tshuaj muaj pes tsawg leeg thiab txhim kho cov hlau zoo.
Nyob rau hauv daim ntawv thov ntawm silicon carbide crucible, lub luag hauj lwm ntawm hlau ce thiab purification tau zoo heev affirmed los ntawm cov neeg siv. Hauv kev lag luam daim ntawv thov crucible, txoj haujlwm ntawm silicon carbide crucible tuaj yeem hais tias yog qhov tseem ceeb.
Vim tias silicon carbide yog ua los ntawmquartz xuab zeb, roj av coke, sawdust thiab lwm yam ntaub ntawv los ntawm high-temperature ce nyob rau hauv lub cub tawg kuj, silicon carbide crucible muaj zoghluav taws kubmuaj peev xwm nyob rau hauv cov kev ua si hlau, yog li nws yog txaus los xyuas kom meej lub siab kub yuav tsum tau rau kev tawm dag zog, zoo heev txo qhov nyuaj ntawm hlau refining, txuag nqi thiab txhim kho daim ntawv thov efficiency.
