Khoom Description

Metallurgical refractories, tshwj xeeb tshaj yog hlau silicon, ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau zoo. Hlau silicon yog ib qho tseem ceeb additive thiab ib qho tseem ceeb ntawm cov alloys siv nyob rau hauv ntau yam lag luam. Nws yog ib qho ci iab, nyiaj-grey metalloid uas feem ntau ntxiv rau cov hlau thiab lwm yam hlau los txhim kho lawv lub zog, ua haujlwm ntev, thiab tiv thaiv corrosion.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv hlau silicon yog nws lub peev xwm los txhim kho cov txheej txheem casting thiab solidification. Thaum ntxiv rau molten steel, hlau silicon pab txo qhov nro thiab txhim kho cov khoom ntws ntawm cov kua. Qhov no, nyob rau hauv lem, ua rau zoo castings nrog tsawg defects thiab zoo dua.

Ntxiv nrog rau nws cov khoom pov thawj, hlau silicon kuj tseem muaj txiaj ntsig zoo li tus neeg sawv cev alloying. Los ntawm kev ntxiv cov hlau silicon rau hlau, nws muaj peev xwm tsim tau cov khoom ruaj khov thiab corrosion-resistant ntau dua. Hlau silicon kuj muaj cov khoom deoxidizing zoo heev thiab tuaj yeem pab tshem tawm impurities ntawm hlau. Nws tseem tuaj yeem pab txhim kho tag nrho cov ductility thiab lub zog ntawm cov hlau, ua rau nws zoo tagnrho rau kev thov hauv kev lag luam tsheb thiab aerospace.

Metallurgical refractories thiab hlau silicon, tshwj xeeb, yog cov khoom tseem ceeb hauv kev tsim cov hlau zoo. Yog tias tsis muaj cov khoom tseem ceeb no, nws yuav nyuaj rau tsim cov hlau uas xav tau lub zog, tiv thaiv corrosion, thiab ductility xav tau rau ntau yam kev siv.

Niaj hnub no, ntau manufacturers tau ua hauj lwm los txhim kho cov txheej txheem ntau lawm kom ua tau zoo ntawm cov txheej txheem. Kev huv thiab ua tau zoo ntawm cov hlau yog ib qho tseem ceeb ntawm kev txhim kho kom ruaj khov. Kev siv cov hlau silicon thiab metallurgical refractories feem ntau yog ib qho tseem ceeb hauv kev ua tiav lub hom phiaj no.

Txawm hais tias hlau silicon, zoo li ntau lwm yam hlau, tej zaum yuav muaj qee qhov kev txhawj xeeb ntawm ib puag ncig thaum lub sijhawm tsim khoom, nws muaj txiaj ntsig ntau dua li qhov tsis zoo nyob rau lub sijhawm ntev. Nrog rau kev tshawb fawb thiab kev tsim kho tshiab, nws muaj peev xwm tsim cov hlau silicon thiab txhim kho cov txheej txheem ntau lawm hauv txoj kev uas txo qis ib puag ncig kev puas tsuaj.

Hauv kev xaus, metallurgical refractories thiab hlau silicon tau muaj txiaj ntsig hauv kev tsim cov hlau zoo uas siv ntau yam lag luam. Lawv tau ua haujlwm tseem ceeb hauv kev txhim kho cov casting, solidification, thiab alloying txheej txheem, ua rau cov khoom zoo dua, muaj zog dua, thiab cov khoom siv hlau ruaj khov. Txawm hais tias muaj qee qhov kev txhawj xeeb ib puag ncig cuam tshuam nrog kev tsim cov khoom siv no, kuj tseem muaj peev xwm tseem ceeb rau kev tsim kho tshiab thiab kev loj hlob hauv cheeb tsam no. Raws li lub zej zog, peb yuav tsum txuas ntxiv txhawb kev tshawb fawb thiab kev loj hlob hauv daim teb no thiab ua haujlwm ua ke kom ruaj khov, huv thiab muaj txiaj ntsig cov txheej txheem tsim khoom uas muaj txiaj ntsig zoo rau peb txhua tus.
