Kev siv thiab siv cov graphite electrodes hauv hluav taws xob arc rauv smelting (6)

Txoj hauv kev tseem ceeb los txo qhov kev siv graphite electrode hauv smelting

Yuav ua li cas txo qhov kev noj ntawm peb lub voj voog electrodes nyob rau hauv smelting tsis yog tsuas yog cov tshuab ntawm carbon manufacturers, tab sis kuj yog ib qho tseem ceeb ua hauj lwm rau smelters koom tes nrog thiab optimize lub lag luam ntawm hluav taws xob furnaces. Raws li kev siv graphite electrodes hauv smelting, thawj qhov yuav tsum tau daws yog qhov teeb meem ntawm cov pob qij txha tawg, thiab qhov thib ob uas yuav tsum xav txog yog oxidation tsis kam thiab thermal shock resistance. Qhov no xav kom peb ua ntej nkag siab txog kev txhim kho kev lag luam smelting, cov txheej txheem smelting, cov txheej txheem ntawm lub tshuab hluav taws xob thiab kev ua haujlwm, thiab tom qab ntawd ua cov phiaj xwm kev tshawb fawb, kev tshawb fawb txog kev tsim khoom, thiab siv cov kev pabcuam zoo. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tiav lub hom phiaj ntawm kev tsim khoom thiab siv. Cov hauv qab no feem ntau yog tham los ntawm kev tsim khoom smelting.

1. Kev txo qis ntawm cov tshuab hluav taws xob tshiab

Lub chaw tsim khoom loj UHP thiab LF hluav taws xob rauv tau tsim lub hauv paus ruaj khov rau kev loj hlob ntawm kev lag luam steel. Muaj peev xwm ntau lawm thiab kev siv hluav taws xob tsawg yog cov yam ntxwv ntawm cov tshuab smelting tshiab. Qhov loj-scale arcs scientific siv ib tug loj ntws ntawm cov tshuaj lub zog (suav txog 60 feem pua ​​​​mus rau 70 feem pua ​​​​ntawm tag nrho cov kev siv zog), thiab kev siv lub tshuab hluav taws xob qis qis, tsis siv neeg cov pa oxygen lances thiab preheating shafts zoo rau ntau tshaj 60 feem pua. kev siv hluav taws xob thiab kev siv hluav taws xob; Daim ntawv thov ntawm cov dej txias txias zoo heev txhim kho lub hnub nyoog ntawm lub cub tawg thiab txo qhov kev siv ntawm cov ntaub ntawv, tshwj xeeb tshaj yog cov tshuaj tsuag dej txias txo cov chav tsev noj ntawm graphite electrode tsawg kawg yog 1/3; Kev siv cov tshuaj siv hluav taws xob ua kom luv lub voj voog smelting tsawg kawg yog ib nrab, thiab txhim kho cov khoom tsim tawm, yog li kev siv cov khoom siv hluav taws xob tsawg zuj zus.

2. Kev txo qis ntawm cov txheej txheem kub smelting

Thaum cov hlau thiab hlau kev lag luam tab tom tsim cov hluav taws xob loj loj, nyob rau xyoo tas los no, nws kuj tau txuas mus rau qhov loj-scale converter thiab blast furnace. Feem ntau ntawm cov khoom siv hluav taws xob tsim tshiab yog tshaj 2000M3 (qhov loj tshaj plaws hauv Suav teb yog 4050M3). Molten hlau converter smelting nrog LF thiab hluav taws xob rauv kub them molten hlau (feem ntau nyob rau hauv 40 feem pua ​​~ 60 feem pua) tau los ua ib tug nrov smelting tshuab; Kev them nyiaj kub tuaj yeem ua kom luv luv lub voj voog smelting, txo kev siv hluav taws xob, hluav taws xob tshuaj thiab ntau yam ntaub ntawv, tshwj xeeb tshaj yog kev noj ib leeg thiab kev thov ntawm graphite electrode.

Hom tshiab ntawm hluav taws xob rauv muaj cov chaw txhawb nqa zoo meej. Kev xaiv ntawm graphite electrodes los ntawm cov cuab yeej siv txawv teb chaws tiv thaiv qhov teeb meem ntawm cov tsheb nees loj tab sis cov tsheb nees me me, uas yog kev sib tw rau cov khoom siv hluav taws xob hauv tsev. Kev ua haujlwm ntawm lub tshuab hluav taws xob impedance thiab kev saib xyuas tsis siv neeg hauv lub tshuab hluav taws xob tau ua lub luag haujlwm zoo hauv kev tswj hwm thiab siv tau zoo ntawm cov electrodes thiab txo qhov poob. Cov electrode breakage tus nqi ntawm lub cub hluav taws xob loj yog tsawg dua 2 feem pua.

Kev hloov pauv ntawm lub qhov cub hluav taws xob qub kuj tseem muaj cov chaw tsim nyog, thiab kev xaiv cov khoom siv hluav taws xob feem ntau txwv, ua rau muaj qhov tshwm sim ntawm quasi-UHP thiab quasi-HP hluav taws xob rauv, uas tsis pom kev txhim kho lub cev zoo ntawm graphite electrodes. ntawm tib qib, xws li: 30T AC siab tiv thaiv hluav taws xob rauv, kev noj ntawm φ450MM HP thiab FG electrodes yog hais txog 1KG, cov electrode tawg yog tsawg dua 3 feem pua, thiab nws tau txais txiaj ntsig zoo los ntawm cov neeg siv, uas kuj yog ib qho kev vam meej hauv carbon technology.

3. nruj me ntsis tswj kev txo qis hauv lub zog xa hluav taws xob

Kev tswj nruj ntawm lub zog xa hluav taws xob yog qhov tsim nyog los xyuas kom meej qhov ua kom zoo li qub. Cov qib steel sib txawv thiab cov txheej txheem smelting muaj qhov sib thooj arc voltage thiab cov iav tam sim no los tiv thaiv kev hloov pauv tam sim no ntau dhau thiab tswj xyuas lub sijhawm ua haujlwm siab tshaj plaws tam sim no. Li no zoo tiv thaiv electrode redness thiab reactive oxidation noj thiab cub tawg.

4. Txuj kev txo qis kev siv

Cov tuam txhab carbon yuav tsum nruj me ntsis los yog qhia cov neeg siv ntawm kev cia thiab kev thauj mus los ntawm electrodes thiab kev sib txuas ntawm electrodes. Tshwj xeeb tshaj yog kev sib txuas tshuab ntawm cov electrodes, nyob rau hauv txoj cai, loj-tsawg electrodes yuav tsum tau txuas nrog nyob rau hauv lub cub tawg; zam kev sib tsoo thiab tsim cov xov tawg thaum sib txuas, thiab yuav tsum khaws cov electrode sab saud rau hauv lub xeev ntsug; Thaum nws sib npaug rau 8 ~ 10MM, siv inertial locking, thiab tom qab ntawd siv lub caj npab ntev los siv lub zog ua ntej kom nruj kom txog thaum nws tsis tuaj yeem ntsia hlau ua ke, thiab cov electrode seamed tsis tuaj yeem muab tso rau hauv qhov cub; yog tias muaj teeb meem nrog cov theem sib lawv liag thiab kev sib txuas zoo, nws yog qhov zoo tshaj kom tsis txhob ntaus tus pin ruaj. Lub hom phiaj ntawm cov kev cai yooj yim no yog kom tsis txhob tawg thiab ua kom poob.

Tsis tas li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them rau: thaum cov nplaim hluav taws kub siab, cov ntu sab saum toj yuav tsum tau txuas nrog qhov siab ntawm electrode nyob rau lub sij hawm kom tsis txhob muaj kev puas tsuaj rau cov xov; thaum zawv zawg electrode, yuav tsum muaj kev sib txuas muag kom tsis txhob muaj kev sib tsoo nyuaj; tus kov thiab lub electrode yuav tsum tau khaws cia nyob rau hauv perpendicular, Tsis txhob khawb lub electrode nrog lub me me rauv cover; zam cov pa oxygen ncaj qha mus rau sab qis electrode nyob rau hauv lub cub tawg, thiab lwm yam. Qhov no yog qhov yuav tsum tau rau kev siv tshuab electrode, thiab lub hom phiaj yog kom tsis txhob thiab txo qhov kev poob ntawm electrode.
