Graphite electrode siv
Graphite electrodes feem ntau yog ua los ntawm roj av coke thiab rab koob coke ua raw khoom thiab thee tar pitch li binder.Lawv yog tsim los ntawm calcining, batching, kneading, nias, roasting, graphitization thiab machining.Lawv raug tso tawm nyob rau hauv daim ntawv ntawm hluav taws xob arcs nyob rau hauv ib tug hluav taws xob arc rauv.Tus neeg xyuas pib uas heats thiab melts tus nqi los ntawm hluav taws xob lub zog yog tsuas yog siv nyob rau hauv hluav taws xob rauv steelmaking.Raws li nws cov txiaj ntsig zoo, nws tuaj yeem muab faib ua lub zog zoo tib yam, lub zog siab thiab lub zog ultra-siab.
(1) Ordinary hwj chim graphite electrode
Graphite electrodes nrog qhov ceev tam sim no qis dua 17A / cm2 raug tso cai siv, uas yog siv rau hauv cov hluav taws xob hluav taws xob zoo tib yam xws li steelmaking, siliconmaking, thiab daj phosphorus smelting.
(2) Graphite electrode nrog anti-oxidation txheej
Graphite electrodes coated nrog anti-oxidation tiv thaiv txheej (graphite electrode antioxidant).Nws tsim cov txheej txheem tiv thaiv uas yog ob qho tib si conductive thiab resistant rau kub oxidation, txo cov electrode noj (19% ~ 50%) thaum lub sij hawm steelmaking, prolongs lub neej kev pab cuam ntawm lub electrode (22% ~ 60%), thiab txo lub hwj chim noj. ntawm electrode.Kev nce qib thiab siv cov thev naus laus zis no tuaj yeem ua rau muaj kev cuam tshuam nyiaj txiag thiab kev sib raug zoo hauv qab no:
① Chav tsev noj ntawm graphite electrode tsawg dua, thiab cov nqi tsim khoom raug txo rau qee yam.Piv txwv li, cov nroj tsuag steelmaking, raws li kev noj ntawm 35 graphite electrodes ib lub lim tiam rau thawj theem LF refining rauv yam tsis muaj kev tsim tawm thoob plaws hauv lub xyoo, thiab kev noj ntawm 165 refining furnaces, tom qab siv graphite electrode los tiv thaiv oxidation technology. , 373 graphite electrodes (153 tons) tuaj yeem txuag tau txhua xyoo.) electrodes, xam ntawm RMB 16,900 ib tuj ntawm ultra-high-power electrodes ib xyoos twg, uas yuav txuag tau RMB 2,585,700.
② Graphite electrodes siv hluav taws xob tsawg, txuag hluav taws xob siv ib chav tsev ntawm steelmaking, txuag nqi ntau lawm, thiab txuag hluav taws xob!
③ Txij li thaum cov graphite electrodes raug hloov tsawg dua, kev ua haujlwm thiab kev pheej hmoo ntawm cov neeg ua haujlwm raug txo qis, thiab kev ua haujlwm tau zoo dua qub.
(3) High-power graphite electrodes.Nws raug tso cai siv graphite electrodes nrog qhov ceev tam sim no ntawm 18-25A / cm2, feem ntau yog siv nyob rau hauv high-power hluav taws xob arc rauv rau steelmaking.
(4) Ultra-siab zog graphite electrodes.Graphite electrodes nrog tam sim no ntom ntau dua 25 A / cm yog tso cai.Feem ntau siv rau ultra-siab zog steelmaking hluav taws xob arc rauv.
