Ua tsaug rau nws cov khoom siv hluav taws xob zoo heev, lub zog siv hluav taws xob, thiab thermal poob siab tsis kam, nws ua kom muaj txiaj ntsig zoo thiab ua haujlwm ruaj khov ntawm lub tshuab hluav taws xob. Cov khoom nruj me ntsis ua raws li lub teb chaws tus qauv GB / T 24273-2017 thiab thoob ntiaj teb tus qauv ASTM C651. Nws muaj kev ua tau zoo ruaj khov thiab sib haum nrog ntau yam khoom siv hluav taws xob hauv ntiaj teb. Nws yog cov khoom siv tseem ceeb rau kev lag luam xws li metallurgy, tshuaj lom neeg kev lag luam, thiab ferroalloy.
Los ntawm kev siv high-cov ntaub ntawv raw khoom thiab kev paub tab tag nrho- cov txheej txheem thev naus laus zis, cov khoom lag luam zoo yog tswj hwm los ntawm qhov chaw. Cov tshuaj ntsuam xyuas zoo tau teeb tsa thoob plaws hauv tag nrho cov txheej txheem:
Kev xaiv cov khoom siv raw: Xaiv siab - koob purity -xws li coke / petroleum coke nrog cov ntsiab lus ntawm cov pa roj carbon ntau dua lossis sib npaug li 98.5%, cov ntsiab lus sulfur tsawg dua lossis sib npaug li 0.5%, thiab cov hmoov tshauv tsawg dua lossis sib npaug li 0.3%. Ua ke nrog ib qho tshwj xeeb thee asphalt binder, nws ua kom cov kev ua tau zoo ntawm cov conductivity thiab siab -kub tsis kam.
Kev kho coking: Cov khoom siv raw yog coked ntawm qhov kub ntawm 1200 ~ 1400℃rau 24 ~ 48 teev, nrog cov teeb meem tsis haum xeeb txo qis dua 0.5%, txhim kho cov qauv kev ruaj ntseg.
Khoom tsim qauv
Electrode lub cev: Tus qauv cylindrical qauv, nrog cov khoom siv hluav taws xob tsis sib xws -section, kom tsis muaj qhov tsis sib xws hauv kev sib kis tam sim no thiab tsis muaj cua sov hauv zos.
Graphite connector: High -lub zog graphite connector ntawm tib yam khoom, txuam lub electrode lub cev kom paub meej tam sim no conduction thiab ruaj khov mechanical kev twb kev txuas.
Xov system: Siv kev lag luam- tshwj xeeb trapezoidal threads nrog taper ntawm 1:16, uas muaj lub zog kaw ntom nti thiab qhov chaw sib cuag loj, ua rau nws tsis tshua muaj kev xoob lossis tawg.
Standard lengths: 1500mm, 1800mm, 2000mm, thiab customization ntawm non- qauv ntev yog txaus siab.
