Hwm UHP graphite electrode rau cov ntawv thov siab heev

Hwm Ushp graphite cov hluav taws xob tau tsim kom tau raws li cov ntawv thov siab, tshwj xeeb hauv cov hluav taws xob arc (EAF) siv rau steelmaking. Lo lus "eltra siab lub zog" yog hais txog electrode lub peev xwm los txhawb nqa siab heev thaum tswj cov txheej txheem kev ntseeg siab thiab kev ruaj ntseg stability. Cov hluav taws xob no tau tsim los ntawm qhov siab -}}}}}}}}}}} agritization ntawm qhov kub tshaj 2,800 degree, thiab precision machining. Qhov txheej txheem tsim qauv ua rau cov khoom siv nrog cov hluav taws xob qis, thiab oxidation tsis kam rau {} Cov haujlwm tseem ceeb rau kev ua haujlwm siab.

Kev ua haujlwm zoo tshaj plaws ntawm UHP Graphite hluav taws xob tso cai rau lawv kom txo qis zog thaum lub sijhawm ua haujlwm, ua kom muaj cov nqi ntau lawm. Lawv lub peev xwm tiv thaiv cov kev hloov pauv sai uas tsis muaj kev tawg lossis spalling yog qhov tseem ceeb hauv EAF ib puag ncig uas kub tau tshaj 3,000 degree. Tsis tas li ntawd, cov hluav taws xob no muaj tsawg heev plua plav thiab tsis tshua muaj coefficient ntawm thermal expansion (CTE), txo qis kev pheej hmoo ntawm kev pheej hmoo thiab kev txhim kho kev nyab xeeb.
