Lub High-zog Graphite hluav taws xob tsim los ntawm kev ua yeeb yam roj av thiab yog ua los ntawm kev ua kom cov khoom siv raw, thiab yog ua los ntawm cov khoom siv raw, thiab yog ua los ntawm kev tso qoob loo, kev xam xam, kev xam xam, graphitization, thiab machiningization, thiab machining. Lawv yog tus coj cov hluav taws xob tso tawm hauv daim ntawv ntawm Arc hauv ib lub tshuab hluav taws xob ua kom sov thiab qhuav cov cub tawg. Raws li lawv cov ntsuas kev ua tau zoo, lawv tuaj yeem muab faib ua cov hluav taws xob zoo tib yam hluav taws xob, cov hluav taws xob muaj hluav taws xob hluav taws xob, thiab cov hluav taws xob ultra graphite electrodes. Graphite hluav taws xob muaj feem ntau siv hauv cov hluav taws xob arc (rau kev tsim cov ferRoalloys, rau kev ua kom huv si silicalys, phosphorus, carbide, thiab lwm yam). Thiab cov cua sov kuj, xws li cov tshuab hluav taws xob rau kev tsim cov graphite electrodes, iav kub yaj, thiab hluav taws xob tshuab hluav taws xob rau kev tsim cov xuab zeb. Tuaj yeem ua tiav raws li cov neeg siv khoom yuav tsum tau siv rau arc rauv stat steelmaking.
Cov khoom kom zoo dua
(1) Qhov kev hloov pauv ntawm cov khoom lag luam thiab cov khoom siv sib txawv ntawm cov khoom siv cov khoom lag luam tau coj mus rau qhov kev tawm ntawm cov khoom siv txim. Qhov zoo ntawm graphite electrodes yog yooj yim kev ua, siab tshem tawm machining kev tshem tawm tus nqi, thiab qis graphite poob. Yog li ntawd, qee pab pawg raws li cov neeg siv hluav taws xob cov neeg yuav khoom tau tso cov hluav taws xob liab thiab hloov mus rau graphite electrodes. Tsis tas li ntawd, qee cov qauv tshwj xeeb zoo nkauj tsis tuaj yeem ua los ntawm tooj liab, tab sis graphite yog qhov yooj yim rau cov hluav taws xob thiab cov khoom lag luam tooj liab tau ua rau kev ua cov electrodes loj. Cov xwm txheej tau ua rau qee pab pawg raws li cov tshuab hluav taws xob raws li cov neeg siv khoom siv graphite electrodes.
(2) Graphite electrodes yog yooj yim rau cov txheej txheem thiab muaj kev sim ua nrawm dua li cov hluav taws xob tooj liab. Piv txwv li, siv cov thev naus laus zis los ua cov txheej txheem graphite, nws lub sijhawm nrawm dua li lwm cov kev ua lag luam hlau, thaum lub sij hawm tooj liab ntxiv tau txais los ntawm kev tuav cov hniav sib tsoo. Ib yam li ntawd, yog cov high-ceev graphite machining chaw yog siv los tsim cov khoom siv hluav taws xob, kev ua tau zoo dua, thiab yuav tsis muaj teeb meem hmoov av. Hauv cov txheej txheem no, xaiv cov cuab yeej uas tsim nyog hardness thiab graphite tuaj yeem txo cov khoom hnav thiab tooj liab electrode. Yog tias muab piv rau lub sijhawm mulling ntawm graphite electrodes thiab tooj liab hluav taws xob, graphite hluav taws xob yog 67% nrawm dua li cov hluav taws xob liab. Feem ntau, hauv kev tawm khoom machining, siv graphite electrodes yog 58% nrawm dua li siv cov hluav taws xob tooj liab. Nyob rau hauv txoj kev no, lub sijhawm ua tau muaj txiaj ntsig tsawg, thaum tseem txo cov nqi tsim khoom.
(3) Cov qauv tsim ntawm graphite hluav taws xob yog txawv ntawm qhov ntawd ntawm cov tsoos tooj liab hluav taws xob. Ntau cov khoom lag luam pwm feem ntau muaj cov nyiaj tshwj xeeb tshwj xeeb rau cov hluav taws xob loj thiab ntsuas phoo ntawm cov nyiaj tooj khaws cia, uas txo cov zaus ntawm cad / cam thiab tshuab ua. Qhov no ib leeg yog txaus kom tau zoo txhim kho qhov tseeb ntawm cov pwm kab noj hniav.
Ua cov ntaub ntawv ntawm cov khoom siv graphite
Muaj peb cov ntaub ntawv tseem ceeb ntawm kev ua graphite electrodes: txhuam kev co qauv, cnc nplauv sib hom qauv, thiab txheej txheem kev ua haujlwm.
Graphite cov ntaub ntawv tuaj yeem siv tau siv cov hau kev xws li tig, milling, drilling, thiab sib tsoo. Ib qho ntxiv, graphite cov ntaub ntawv yog qhov nquag ya tshauv kom ya lub sijhawm ua haujlwm, uas muaj cov kev tsis zoo ntawm kev ua cov khoom siv thiab cov neeg ua haujlwm.
Ua cov ntaub ntawv ntawm cov khoom siv graphite
(1) Ntau lawm ntau lawm voj voog. Lub voj voog ntau ntau ntawm cov hluav taws xob zoo li hluav taws xob graphite hluav taws xob yog li 45 hnub, thiab lub zog ntau lawm graphite hluav taws xob muaj ntau dua 70 hnub. Txawm li cas los xij, lub voj voog ntau ntawm graphite electrode pob qij txha uas yuav tsum muaj ntau impregnations ntev dua.
(2) siv hluav taws xob ntau. Kev tsim tawm 1 tuj ntawm lub zog loj graphite hluav taws xob yuav tsum muaj kwv yees li 6000 kuas lub zog hluav taws xob, ntau txhiab, thiab kwv yees li 1 tuj ntawm sib tw coke thiab hmoov.
(3) Muaj ntau cov txheej txheem ntau lawm. Cov txheej txheem ntau lawm suav nrog raw cov ntaub ntawv cais, crushing thiab sib tsoo, ci, imprite, impritization, thiab kev ua tshuab. Nws ntau lawm cov khoom siv tshwj xeeb thiab cov khoom siv nrog cov qauv tshwj xeeb, thiab kev siv peev txheej tshwj xeeb, nrog rau lub sijhawm ntev kev nqis peev.
(4) Muaj qee qhov nyiaj ntawm cov av thiab cov roj teeb meem yog tsim kev tiv thaiv thiab cov plua tshauv txo kev tiv thaiv ib puag ncig kom tshem tawm cov roj teeb meem tshem tawm.
(5) Cov ntaub ntawv uas yuav tsum muaj roj carbonegaceous rau ntau lawm, xws li roj av coke thiab cov khoom siv pob zeb ua kom zoo nkauj thiab thee kev lag luam. Qhov zoo thiab ruaj khov ntawm cov ntaub ntawv raw yog qhov nyuaj rau kev lav ris, thiab cov ntsiab lus tsis zoo siv nyob rau hauv high-zog thiab ultra-siab graphite qhuav electrode ntau yam elecite electrode. Nws yog tus maj nrawm rau Tuam Tshoj cov roj av thiab cov khoom siv hluav taws xob ua haujlwm ntsuas kom ua tiav qhov tseem ceeb rau thiab nquag koom tes nrog thiab nquag koom tes.
