Dab tsi yog cov khoom tseem ceeb ntawm graphite cov khoom siv hauv steelmaking?

Lub graphite electrode cov khoom siv hauv kev siv roj hlau yog ib qho khoom siv tshwj xeeb uas ua rau nws ua kom zoo tshaj plaws rau kev coj ua hluav taws xob hauv hluav taws xob (EAF). Cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob muaj cov hluav taws xob muaj hluav taws xob siab, muaj zog dua rau cov cua sov thiab oxidation.

Hluav Taws Xob Ua Haujlwm:

Graphite yog ib tug neeg saib xyuas hluav taws xob zoo, uas yog qhov tseem ceeb rau kev hloov siab hloov siab los ntawm lub zog rau arc. Tsawg cov hluav taws xob tsis kam qeeb zog raws li cua sov raws li tshav kub tsis pub dhau lub electrode nws tus kheej, txhim kho cov nqi zog thiab txo cov nqi ua haujlwm.

Thermal Condivity:

Siab thermal conductivies tso cai rau cov graphite electrode rau faib cov neeg mob hnyav kom raws li nws qhov ntev los ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm kev ntxhov siab thermal lossis tawg. Cov cuab yeej no yog qhov tseem ceeb rau kev tswj cov qauv txheej txheem ntawm cov electrode thaum lub sijhawm ua haujlwm.

Neeg kho tshuab zog:

Graphite electrodes yuav tsum tau tiv thaiv cov kev ntxhov siab tshwj xeeb tshwm sim los ntawm lawv tus kheej lub cev hnyav, thermal nthuav dav, thiab cua sov vibrations. High aluminium zog kom ntseeg tau tias cov electrodes tiv thaiv tawg thiab deformation nyob rau hauv cov kev mob no, pab txhawb kev ua haujlwm ntev dua.

Thermal poob siab:

Cov khoom siv yuav tsum tau mob siab sai uas yam tsis muaj kev tawg lossis tawg. Graphite cov muaj peev xwm tiv thaiv bondal poob siab ua rau nws zoo-}}}}}} kub hloov pauv hloov pauv tau ntau dua thaum lub voj voog melting.

Oxidation tsis kam:

Txawm hais tias ib txwm muaj oxidizes ntawm cov kub, siab {{}} Cov hluav taws xob zoo tau kho lossis tswj tau kev ua tau zoo hauv oxygen {}} rugospheres.

Purity:

Siab - purity graphite, feem ntau ua los ntawm refinumum coke thiab ua kom muaj zog tsawg kawg nkaus uas tuaj yeem paug cov hlau lossis cuam tshuam rau cov khoom lag luam hluav taws xob. Kev impurities kuj tseem tuaj yeem txo cov hluav taws xob thiab cov khoom cua sov.

Ua ke, cov khoom no ua kom haum electrode cov khoom siv tsis zoo, txhim khu kev qha, thiab high - zoo ntau lawm hauv cov txheej txheem metallurgical.
