Kev siv thiab siv cov graphite electrodes hauv hluav taws xob arc rauv smelting (7)

Txoj kev loj hlob ntawm smelting technology thiab kev thov rau electrodes

Lub tshuab hluav taws xob arc rauv hauv Tuam Tshoj txoj kev lag luam hlau thiab hlau tau dhau los ua tus qauv ntawm kev loj hlob sai mus rau qhov loj, uas yog tus cwj pwm los ntawm cov khoom siv hluav taws xob loj, lub zog ruaj khov coefficient, kev ua haujlwm ntev arc thiab txuag hluav taws xob thiab txo kev noj. Yog li ntawd, piv nrog cov tsoos hluav taws xob arc rauv yav dhau los, lub qhov cub hluav taws xob loj tshiab tau hloov pauv zoo. Lub tshuab hluav taws xob niaj hnub siv hluav taws xob tau them nyiaj zoo rau qhov teeb meem ntawm hluav taws xob hluav taws xob. Kev siv phom dav hlau thiab cov pa roj carbon tsis siv neeg thiab cov phom oxygen tuaj yeem txo cov electrode noj ntawm 0.3 ~ 0.5KG ib tuj ntawm cov hlau. Nrog rau kev siv cov thev naus laus zis kub, lub sijhawm smelting yog pom tseeb luv luv, thiab kev siv hluav taws xob thiab hluav taws xob tau pom tseeb txo qis.

Cov hluav taws xob loj arc rauv txhua qhov siv lub peev xwm loj thiab lub peev xwm tshaj yog 20 feem pua. Los ntawm qhov kev pom no, cov kev xav tau ntawm graphite electrode hauv hlau thiab hlau smelting yog siab dua thiab siab dua, tshwj xeeb tshaj yog qhov zoo sib npaug, conductivity, thermal shock resistance thiab oxidation tsis kam ntawm electrode. Rau nruab nrab lossis loj arc rauv thiab ua haujlwm offline permeance LF rauv tab sis muaj ib qho teeb meem, xws li: UHP hluav taws xob mus offline electrodes nrog lub zog siab, HP lub qhov cub mus offline electrode siv lub zog zoo tib yam, qhov tshwm sim ntawm lub cub hluav taws xob yog qhov nyuaj rau kev lag luam thiab mus rau qhov kev sim ntawm cov khoom siv tsoos, kuj tseem yuam cov tuam txhab lag luam muab cov khoom siv hluav taws xob tsawg-zoo quasi siab zog thiab cov khoom siv hluav taws xob ultra-siab. Vim tias txoj kev loj hlob ntawm cov hlau thiab hlau tau dhau los ntawm qhov ntau ntawm qhov ze, nyob rau hauv cov kev taw qhia ntawm kev loj hlob ntawm cov khoom zoo thiab ntau yam tshwj xeeb.

Loj DC thiab AC arcs kuj tau ua tiav; muaj peev xwm, loj-scale thiab loj-scale blast furnaces txhawb dual-chaw nres tsheb LF furnaces tau los ua ib tug tshiab txoj kev loj hlob kev taw qhia. Tsis tas li ntawd, qhov loj-scale submerged arc rauv kuj tau pib ua zoo.

Tam sim no kev lag luam thov rau graphite electrodes tau tsim nyob rau hauv cov kev taw qhia ntawm ntau yam thiab increments. Ntawm lawv: qhov kev thov txhua xyoo rau UHP graphite electrodes yuav ncav cuag 100, 000 tons; qhov kev thov txhua xyoo rau HP graphite electrodes yog tsawg kawg yog 180, 000 tons; qhov loj-teev φ500MM thiab φ600MM electrodes rau HP graphite electrodes kuj txav mus rau ib qho incremental kev taw qhia (feem ntau submerged arc furnaces).
