INCAZELO

I-electrode ye-graphite ye-UHP isetshenziselwa ukuphinda kusetshenziswe insimbi embonini yesithando sikagesi se-arc. Isithako sayo esiyinhloko yi-needle coke enenani eliphezulu eyenziwe nge-petroleum noma i-coal tar. Ama-electrode e-graphite aqedwa ngesimo sesilinda futhi afakwe izintambo ekugcineni ngakunye. Ngale ndlela, ama-electrode e-graphite angahlanganiswa abe yikholomu ye-electrode kusetshenziswa i-electrode nipple.

Ukuze kuhlangatshezwane nesidingo sokusebenza kahle okuphezulu kanye nezindleko eziphansi, izitofu ze-arc ezinamandla amakhulu kakhulu ziya ngokuya zithandwa kakhulu. Ngenxa yalokhu, ama-electrode e-graphite e-UHP anobubanzi obungaphezu kwama-500 mm azobusa imakethe.

Isici

Ibekezelela imisinga emikhulu, izinga lokukhishwa eliphezulu.
Ukuqina okuhle kobukhulu, akulula ukukuguquguqula.
Ayikwazi ukuqhekeka nokuqhekeka.
Ukumelana okuphezulu ne-oxidation kanye nokushaqeka kokushisa.
Amandla aphezulu okusebenza ngomshini, ukumelana okuphansi kukagesi.
Ukunemba okuphezulu komshini, ukuqedwa okuhle kwendawo.

ISICELO

Kufanele kube neziphambeko noma imigodi engaphansi kwemibili ebusweni be-electrode, ubukhulu bayo obukhulu bushiwo eshadini elingezansi.
Akufanele kube khona ukuqhekeka okuphambeneyo ebusweni be-electrode. Ku-crack ende, ubude kufanele bube ngaphansi kuka-5% womjikelezo we-electrode kanti ububanzi kufanele bube ngu-0.3 kuya ku-1.0 mm.
Ububanzi bendawo emnyama ebusweni be-electrode kufanele bube ngaphansi kwe-1/10 yesiyingi se-electrode futhi ubude kufanele bube ngaphansi kwe-1/3 ye-electrode.
