Vim li cas lub electrode sib koom tes ib qho tseem ceeb ntawm cov txheej txheem steelmaking?
Qhov sib koom ua ke yog qhov tsis muaj zog tshaj plaws hauv cov kem tag nrho, tsis tau nws bears qhov hnyav tshaj (mechanically thiab hluav taws xob). Cov teeb meem tshwm sim muaj xws li:
• Txo thiab ua kom nruj: Kev ntxhov siab rau kev ntxhov siab tuaj yeem ua rau cov kev puas tsuaj, ua rau muaj kev cuam tshuam thiab kev poob qis.
• Cov kab mob hlawv tawm: Cov kab sib koom tes sib koom tes yog cov tshuaj tiv thaiv oxidation, tsim "mem tes -} {qhov tsis muaj zog ntawm kev sib koom ua ke thiab ua rau nws tawg.
• Tsis zoo tuaj yeem kis tam sim no: xoob kev sib txuas lus tuaj yeem ua rau arcing, hauv ib cheeb tsam overheating, thiab sib zog sib faib. Yog li ntawd, nws yog qhov tsim nyog los siv lub zog ua kom huv si los ntxuav thiab ua kom nruj cov pob qij txha raws li cov lus qhia tshwj xeeb.
Ib -} Nres kev pabcuam rau kev ua kom zoo
Peb cov kws tshaj lij yog cov kws tshaj lij cov kws tshaj lij nrog kev txawj ntse hauv EAF, Lady, thiab Casting cov ntawv thov. Peb muab kev txhawb nqa dav rau ultra - siab- fais fab graphite electrodes, suav nrog:
Kev tshuaj xyuas thiab ntsuas ntawm cov neeg siv hluav taws xob cov neeg ua kom sov los txhim kho cov khoom lag luam electrode thiab txo qis noj.
Cov kev pab ntxiv xws li kev qhia ua neeg ua haujlwm, kev ntsuas kev ua tau zoo, chaw khaws khoom lag luam, khoom siv mus cuag, thiab ua kom nrawm nrawm.
