Dab tsi yog qhov Kev siv lub ntsiab 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 siv los ua ib qho khoom siv los yog ua ke nrog qee cov khoom siv refractory, muaj cov txheej txheem tshwj xeeb hauv kev tsim khoom, thiab yuav luag txhua cov ntaub ntawv raug xaiv nrog kev ua haujlwm siab. -end refractory cov ntaub ntawv, xws li magnesia carbon cov ntaub ntawv, aluminium carbon cov ntaub ntawv, zirconium carbon cov ntaub ntawv, corundum-raws li zirconia cov ntaub ntawv, thiab lwm yam., thiab feem ntau ntawm cov functional refractories siv tam sim no yog carbon-muaj 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 zawv zawg nto tiv thaiv thermal shock ntawm high-temperature molten steel thaum siv thiab hnav ntawm zawv zawg nto thaum tswj kev khiav: nruam casting ntev nozzle, ib qho stopper, immersion hom Lub nozzle yog raug rau lub thermal shock ntawm molten steel thiab lub zog yaig ntawm slag kua thaum lub sij hawm pouring;

Thaum lub sij hawm siv, cov cua-permeable cib yog raug rau lub zog thermal voj voog ntawm cov txheej txheem kev khiav hauj lwm thiab cov nyhuv yaig ntawm cov hlau molten nyob rau hauv agitation ntawm huab cua ntws, thiab hais txog. Nrog rau kev txhim kho tas mus li thiab kev loj hlob ntawm kev nruam casting technology, muaj ntau dua thiab siab dua qhov yuav tsum tau ua rau lub neej ua haujlwm thiab kev ua haujlwm ntawm kev ua haujlwm refractories.

Yog li ntawd, cov kev xav tau ntau tshaj plaws rau castables: txhawm rau ua kom muaj kev nyab xeeb, kev ntseeg tau thiab lub neej ua haujlwm ntev nyob rau hauv kev siv hnyav, kev ua haujlwm tsis zoo rau kev nruam casting yuav tsum muaj siab thermal shock resistance, spalling resistance, thiab siab corrosion kuj. Thiab cov yam ntxwv sib xws uas yuav tsum muaj nyob rau hauv thiaj li yuav ua tiav nws txoj haujlwm.
