Cov Khoom Paub meej
Cov electrodes nqa cov hluav taws xob uas heats hluav taws xob arc furnaces, feem ntau steel furnaces. Lawv yog tsim los ntawm cov roj av coke tom qab nws tov nrog roj av, extruded thiab zoo li tus, ces ci rau sinter nws, thiab ces graphitized los ntawm cua sov nws saum toj no qhov kub (3000 ° C) uas converts carbon rau graphite. Lawv tuaj yeem sib txawv hauv qhov loj txog 11 ft. ntev thiab 30 nyob rau hauv txoj kab uas hla.
Kev siv
- 01 Kev nce qib ntawm cov hlau thoob ntiaj teb yog tsim los ntawm cov hluav taws xob arc rauv taws
- 02 Lub tshuab hluav taws xob arc rauv nws tus kheej tau txais txiaj ntsig ntau dua thiab ua rau cov hlau ntau dua ib tonne ntawm electrode
