HP Graphite elektrode
Tlhaloso
Sehlahisoa sena se sebelisoa haholo bakeng sa sebōpi sa arc ea matla a phahameng e le thepa e tsamaisang, motlakase o phahameng oa graphite o ile oa hlahisoa ka thepa e tala ea boleng bo phahameng 'me boleng bo laoloa ka thata nakong ea tlhahiso ea lihlahisoa.Lihlahisoa tsa rona li hapile tšepo ea basebelisi ka boleng bo botle, theko e utloahalang le tšebeletso e hlokolosi.
Re na le li-electrode tsa graphite tsa HP bophara ba 100-700mm.
Sebopeho
1.Matla a phahameng a mochine, ho hanyetsa motlakase o fokolang.
2. Bohloeki bo phahameng, boima bo phahameng, botsitso bo matla ba lik'hemik'hale.
3.Ho nepahala hoa machining, ho qeta holimo holimo.
4.Ho hanyetsa ka matla ho oxidation le mocheso oa mocheso.
Kalafo ea 5.Anti-oxidation bakeng sa bophelo bo bolelele.
6. E manganga ho petsoha & spalling.
Litlhoko tsa boleng
1.Ho lokela ho ba le liphoso tse ka tlase ho tse peli kapa masoba holim'a sebaka sa electrode.
2. Ha hoa lokela ho ba le mapetso a pota-potileng holim'a sebaka sa electrode.Bakeng sa ho petsoha ha longitudinal, bolelele bo lokela ho ba tlase ho 5% ea sedikadikwe sa electrode le bophara bo lokela ho ba 0.3 ho isa ho 1.0 mm.
3. Bophara ba sebaka se setšo holim'a electrode holim'a metsi e lokela ho ba tlase ho 1/10 ea selika-likoe sa electrode 'me bolelele bo lokela ho ba tlase ho 1/3 ea electrode.

Li-index tsa 'mele le tsa lik'hemik'hale tsa li-electrode le li-nipples tsa matla a phahameng li bua ka YB/T 4089-2015.
