Lub tshuab hluav taws xob arc rauv (EAF) yog ib hom hluav taws xob rauv uas ua kom kub kub los ntawm electrode arc kom yaj ore thiab hlau. Thaum cov pa paug tawm ua ib qho arc, nws tsim ib qho chaw muaj zog muaj zog nrog qhov kub siab tshaj 3000 degree. Qhov kub kub no ua rau EAFs zoo heev rau cov hlau smelting, muab kev yooj yim dua hauv cov txheej txheem piv rau lwm cov hlau ua rauv taws. Lawv ua tau zoo ntawm kev tshem tawm impurities xws li sulfur thiab phosphorus los ntawm cov hlau. Tsis tas li ntawd, qhov cub kub kub tswj tau yooj yim, thiab cov khoom siv yuav tsum muaj qhov chaw me me, ua rau EAFs zoo tagnrho rau melting high-zoo alloy steel.
EAFs tuaj yeem muab faib los ntawm daim ntawv arc rau hauv peb-theem hluav taws xob arc rauv, hluav taws xob siv hluav taws xob arc rauv, ib-theem hluav taws xob arc rauv, thiab hluav taws xob hluav taws xob arc furnaces. Lub tshuab ua kom sov muaj xws li lub qhov cub npog, lub qhov cub qhov cub, tapping spout, thiab lub tshuab ua kom sov lub cev, nrog rau hauv qab thiab phab ntsa nrog cov khoom alkaline lossis acidic refractory.
kev siv hluav taws xob Arc furnaces
Electric arc furnaces nrhiav kev siv dav hauv:
Hlau Ntau Lawm
EAFs yog qhov tseem ceeb hauv kev tsim cov hlau los ntawm cov khoom siv raw xws li hlau ore lossis rov siv cov khoom seem rau hauv cov khoom hlau tshiab.
Foundries
Siv rau melting thiab refining hlau rau casting txheej txheem.
Alloy Production
EAFs ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom tshwj xeeb nrog cov tshuaj muaj tseeb.
yuav ua li cas xaiv cov hluav taws xob Arc furnaces koj xav tau
1. Hom khoom: Txiav txim siab hom hlau koj yuav tsum tau ua, xws li hlau, hlau, alloys, thiab lwm yam.
Muaj peev xwm: Ntsuas qhov ntim ntawm cov hlau uas koj xav tau los ua ib pawg thiab cov haujlwm ntau zaus hauv ib hnub / lub lim tiam.
2. Kev qhia tshwj xeeb
Hom EAF: Xaiv ntawm Direct Current Electric Arc Rauv (DC EAF) los yog Alternating Current Electric Arc Rauv (AC EAF) raws li koj xav tau ntau lawm.
Electrode System: Nkag siab txog hom thiab kev ua tau zoo ntawm lub tshuab electrode, suav nrog electrode lifespan, hloov zaus, thiab cov nqi khiav lag luam.
3. Tswj thiab Automation Muaj peev xwm
Tswj System: Ntsuam xyuas qhov kev ua haujlwm ntawm lub tshuab hluav taws xob tswj qhov system, suav nrog kev tswj qhov kub thiab txias, arc tswj, thiab automation nta.
Cov ntaub ntawv sau thiab tshuaj xyuas: Xyuas seb lub tshuab hluav taws xob puas txhawb nqa cov ntaub ntawv sau thiab tshuaj xyuas kom zoo dua cov txheej txheem tsim khoom thiab kev tswj kom zoo.
hom hluav taws xob arc rauv
Muaj ntau txoj hauv kev los faib cov hluav taws xob arc rauv taws.
Raws li daim ntawv melting ntawm electrode, nws tuaj yeem muab faib ua
(1) Non-consumable electrode type electric arc furnace, uas siv tungsten lossis graphite ua cov electrode. Cov electrode nws tus kheej tsis noj los yog noj tsawg heev thaum lub sij hawm melting txheej txheem.
(2) Consumable electrode type hluav taws xob arc rauv, uas siv cov hlau yuav yaj raws li cov electrode. Cov hlau electrode yog siv thaum melting.
Raws li txoj kev tswj ntawm qhov ntev arc, nws tuaj yeem muab faib ua
(1) Tsis tu ncua arc voltage tsis siv neeg tswj hom hluav taws xob arc rauv, uas tso siab rau kev sib piv qhov hluav taws xob ntawm ob lub electrodes nrog qhov muab hluav taws xob. Qhov txawv yog amplified los ntawm lub teeb liab tsav lub consumable electrode nce thiab poob kom lub arc ntev tsis tu ncua.
(2) Tsis tu ncua arc ntev tsis siv neeg tswj hom hluav taws xob arc rauv, uas tso siab rau qhov tsis tu ncua arc voltage kom kwv yees tswj qhov ntev arc tas li.
(3) Droplet mem tes tsis siv neeg tswj hom hluav taws xob arc rauv, uas cia li tswj cov arc qhov ntev raws li cov mem tes zaus generated thaum lub sij hawm tsim thiab dripping ntawm cov hlau droplet thiab kev sib raug zoo ntawm cov mem tes ntev thiab arc ntev.
Raws li daim ntawv ua haujlwm, nws tuaj yeem muab faib ua
(1) Periodic lag luam hom hluav taws xob arc rauv, uas yog, txhua lub qhov cub tawg raug suav tias yog lub voj voog.
(2) Kev ua haujlwm tsis tu ncua hluav taws xob arc rauv. Muaj ob hom ntawm no hom hluav taws xob arc rauv. Ib qho yog lub cub tawg; lwm qhov yog DC fais fab mov sib koom los ntawm ob lub qhov cub. Ntawd yog, thaum ib lub cub tawg tiav lawm, cov khoom siv hluav taws xob hloov mus rau lwm lub qhov cub kom pib smelting lub cub tawg tam sim ntawd.
Raws li cov qauv ntawm lub cub tawg, nws tuaj yeem muab faib ua
(1) Tsau hluav taws xob arc rauv.
(2) Rotating hluav taws xob arc rauv.
