Txuj: Q/L YS{0}} Series ntawm alumina -graphite refractory khoom rau Con-casting
Upper nozzles
Nws txoj hauj lwm yog ncaj qha mus rau hauv lub rooj zaum cib, thiab cov khoom yuav tsum tau tiv taus kub, yaig, thiab yaig, yog li lub neej kev pab cuam ntev dua li ntawm skateboard cib. Sab saum toj nozzle muab faib ua breathable thiab non-breathable nyob rau hauv cov qauv. Lub ventilating qaum nozzle feem ntau yog siv nyob rau hauv lub zawv zawg nozzle ntawm tundish, thiab nws muaj nuj nqi yog los txo qhov txhaws ntawm lub nozzle thiab txhim kho qhov zoo ntawm molten hlau. Floating nyob rau hauv lub crystallizer. Cov khoom siv ntawm lub nkoj yog aluminium carbon, corundum los yog mullite, thiab lwm yam. Yuav kom txhim kho kev ua tau zoo ntawm cov khoom siv nozzle, ib qho me me ntawm thiab qee zaum ntxiv los txhim kho kev yaig tsis kam ntawm lub nozzle cib.
qis nozzles
Nws yog tsuas yog siv los tswj qhov ntws thiab ntws tus nqi ntawm cov hlau molten, thiab yuav tsum muaj kev yaig zoo thiab qhov kub siab ntim ruaj khov ntawm qhov kub thiab txias. Cov ntaub ntawv tseem ceeb yog siab aluminium, aluminium carbon thiab aluminium zirconium carbon. Lub ntsiab yog vim li cas rau kev puas tsuaj yog: yaig thiab scouring ntawm molten hlau thiab slag, tawg los yog puas los ntawm kub poob siab, thiab melting poob los ntawm burning oxygen. Txhawm rau txhim kho cov thermal shock tsis kam ntawm cov dej ntws, cov dej ntws tau muab tso rau hauv lub tes tsho hlau los tiv thaiv kev tawg. Thaum siv, sim kom tsis txhob hlawv cov pa oxygen., cov cim qhia ntawm lub cev thiab tshuaj lom neeg ntawm lub siab thiab qis nozzle cib ua nyob rau hauv Suav teb tau qhia.
