Cov Lus Qhia Txog Graphite Electrode

Cov Khoom Siv Hluav Taws Xob Graphite

Cov graphite electrodes feem ntau yog siv rau hauv kev tsim cov hlau hluav taws xob arc vim tias lawv muaj cov khoom ntawm kev ua hluav taws xob siab.

Kev piav qhia

Tam sim no cov graphite electrodes yog cov khoom lag luam nkaus xwb uas muaj cov hluav taws xob conductivity siab thiab muaj peev xwm tswj tau cov cua sov siab heev uas tsim tawm hauv qhov chaw nyuaj no. Lawv siv los ua kom cov hlau zoo hauv cov cub tawg thiab lwm yam txheej txheem smelting. Cov no ua haujlwm ua cov hluav taws xob hauv lub cub tawg, tsim kom muaj cua sov txaus los yaj cov hlau seem, hlau ore lossis lwm yam khoom siv raw siv los tsim cov hlau lossis lwm yam hlau. Hauv lub cub tawg ib txwm siv hluav taws xob hloov pauv thiab ua haujlwm ntawm tus lej ntawm cov voj voog ntau lawm hauv ib hnub, ib qho ntawm cuaj lub electrodes raug siv tag nrho (yuav tsum tau ntxiv lub electrode tshiab), qhov nruab nrab, txhua yim txog kaum teev ua haujlwm. Qhov tseeb ntawm kev siv thiab ntxiv cov electrodes rau ib lub cub tawg tshwj xeeb nyob ntawm qhov ua haujlwm zoo thiab kev tsim khoom ntawm lub cub tawg.
