Qhov tseem ceeb ntawm cov khoom siv refractory
Cov yam ntxwv ntawm cov khoom siv refractory: Lub luag haujlwm tshwj xeeb ua haujlwm los ntawm cov txheej txheem metallurgical hauv kev siv feem ntau yog siv los ua ib feem lossis ua ke nrog qee cov khoom siv refractory, ntau lawm muaj cov txheej txheem tsim tshwj xeeb, thiab cov khoom xaiv yuav luag txhua qib high-qib refractory. cov ntaub ntawv uas muaj kev ua tau zoo, xws li magnesium carbon cov ntaub ntawv, aluminium carbon cov ntaub ntawv, zirconium carbon cov ntaub ntawv, corundum zirconium oxide cov ntaub ntawv, thiab lwm yam. Tam sim no, feem ntau ntawm cov functional refractories siv yog carbonaceous refractories.
Kev ua tau zoo ntawm cov khoom siv refractory: kev siv cov khoom siv ntawm cov khoom siv refractory yog qhov hnyav, xws li thermal cuam tshuam ntawm cov skateboard siv thiab hnav ntawm zawv zawg nto thaum lub ntws yog tswj: qhov ntev nozzle rau nruam casting, tag nrho. plug pas nrig, thiab lub immersion nozzle yog raug rau thermal cuam tshuam ntawm cov kua hlau thaum lub pouring pib thiab muaj zog yaig ntawm lub slag thaum lub sij hawm pouring;
Lub cib breathable yog raug rau lub zog thermal ncig hauv cov txheej txheem kev ua haujlwm thiab kev yaig ntawm cov hlau molten nyob rau hauv qhov agitation ntawm huab cua ntws. Nrog rau kev txhim kho tas mus li thiab kev loj hlob ntawm kev siv thev naus laus zis txuas ntxiv, muaj ntau dua thiab ntau dua qhov yuav tsum tau ua rau lub neej ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv refractory.
Yog li ntawd, cov kev xav tau ntau tshaj plaws rau castables: txhawm rau ua kom muaj kev nyab xeeb thiab kev ntseeg tau nyob rau hauv cov xwm txheej hnyav ntawm kev siv thiab kev ua haujlwm siab, kev ua haujlwm refractories rau nruam casting yuav tsum muaj thermal poob siab tsis kam thiab spilling tsis kam, siab yaig kuj thiab cov yam ntxwv ntawm cov qauv. txhawm rau ua si nws lub luag haujlwm.
