Graphite Electrodia Innovating steelmakaking li cas? 

Kev siv cov graphite electrodes hauv statmakakinguse siv ntawm graphite hluav taws xob hauv steelmaking yog qhov tseem ceeb rau kev tsim khoom thiab zoo steel thiab zoo steel ntau lawm. Kab lus no muab cov kev qhia dav dav ntawm lawv daim ntawv thov, tsom mus rau lawv cov khoom, thiab kev cuam tshuam tag nrho ntawm cov txheej txheem statmaking.

Dab tsi yog graphite electrodes?

Graphite electrodes yog cov cheebtsam tseem ceeb hauv hluav taws xob arc rhuab hluav taws (EAFs), siv dav hauv cov txheej txheem steel qub. Lawv tsim los ntawm high-purity petroleum coke thiab suab, raug rau kev ua kom muaj hluav taws xob tshwj xeeb ua haujlwm, lub zog, thiab thermal poob siab kuj. Lawv lub luag haujlwm tseem ceeb yog los ua hluav taws xob tam sim no los ntawm lub zog hluav taws xob rau Molten Steel Da dej, muab lub zog tsim nyog rau kev siv hluav taws xob melting thiab muab cov hlau. Qhov zoo thiab ua tau zoo ntawm Graphite electrodes Ncaj qha cuam tshuam rau tag nrho cov txiaj ntsig zoo thiab raug nqi zoo ntawm kev ua haujlwm steelmaking.

Cov Khoom Siv Ntawm Graphite Electrodes rau Steelmaking

Kev Ua Hluav Taws Xob Kev Zoo Tshaj

Graphite electrodes Muaj peev xwm tshwj xeeb hluav taws xob kev ua haujlwm siab, tso cai rau kev hloov hluav taws xob kom zoo rau lub zog hluav taws xob rau cov hlau Molten. Qhov no txo ​​qis zog poob thiab ua rau muaj kev txuag nqi hauv cov txheej txheem statmaking. Hebei Yaofa carbon Co., Ltd. (https://www.yafatansu.com/) yog cov chaw tsim khoom lag luam ntawm cov khoom siv zoo Graphite electrodes nto npe rau lawv cov kev coj zoo tshaj plaws.

Graphite electrodes Yuav tsum tiv thaiv cov thermal shocks tsis muaj pob txha lossis tsis muaj kev txwv. Lawv lub siab thermal poob siab kuj ua rau lub neej ua haujlwm ntev ntev thiab txo cov zaus ntawm cov khoom siv hluav taws xob. Qhov no muaj peev xwm ua rau tag nrho cov khoom lag luam tag nrho thiab kev ua haujlwm ntawm cov nroj tsuag steelmaking.

Siab lub zog thiab kev ruaj khov

Kev tsim khoom txheej txheem ntawm cov zoo-zoo Graphite electrodes Cov txiaj ntsig hauv kev kho tshuab muaj zog thiab kav ntev. Qhov no ua rau lawv tiv thaiv cov mob hnyav hauv EAF, suav nrog kev ntxhov siab txhua yam thiab tshuaj yaig. Lub zog ntawm cov hluav taws xob no yog qhov ua tau zoo ib yam thoob plaws hauv cov txheej txheem steelmaking.

Lub luag haujlwm ntawm graphite electrodes hauv cov txheej txheem steelmaking

Hauv EAF statmaking, Graphite electrodes yog qhov tseem ceeb rau ob peb kauj ruam tseem ceeb:

SAUL MELTING

Lub electrodes hloov hluav taws xob hluav taws xob kom lub zog siv hluav taws xob, kom sai tau melting nws los ua tus da dej molten steel da dej. Kev ua tau zoo ntawm cov txheej txheem no yog cuam tshuam ncaj qha los ntawm qhov zoo ntawm cov hluav taws xob siv. Ib qho kev ua tau zoo dua los ua kom nrawm dua melting thiab nce cov khoom lag luam.

Refining Cov Hlau Molten

Thaum cov steel yog molten, tus Graphite electrodes Txuas ntxiv mus ua ib lub luag haujlwm tseem ceeb hauv cov txheej txheem ua kom zoo dua. Lub arc tsim los ntawm cov electrodes muab lub zog tsim nyog rau kev tswj qhov kub thiab tshem tawm impurities, thiab ua tiav cov khoom xav tau siv.

Alloying thiab degassing

Cov tswj kev thov ntawm hluav taws xob lub zog los ntawm Graphite electrodes yog qhov tseem ceeb nyob rau hauv cov kev sib cav sib ceg thiab degassing theem ntawm steelmaking, kom ntseeg tau cov khoom kawg uas ua tau raws li cov qauv tshwj xeeb thiab cov qauv zoo.

Hom thiab ntau thiab tsawg ntawm graphite electrodes

Graphite electrodes Muaj nyob rau hauv ntau qhov diameters thiab ntev kom haum rau ea sib txawv thiab ntau lawm yuav tsum tau ua. Kev xaiv ntawm electrode loj thiab hom yog qhov tseem ceeb heev hauv kev txhim kho cov txheej txheem steelmaking. Cov ntsiab lus los txiav txim siab suav nrog cov cua sov muaj peev xwm, cov hom phiaj ntau lawm, thiab lub hom phiaj zog ntau lawm.
