Extrusion yog txheej txheem tsim khoom siv los tsim cov khoom ntawm tus ntoo khaub lig ruaj khov -sectional profile los ntawm kev thawb cov khoom los ntawm kev tuag ntawm qhov xav tau ntoo khaub lig-section. Thaum nws los txog rau graphite ingots, cov txheej txheem extrusion yog ib kauj ruam tseem ceeb uas yuav tsum tau muaj qhov tseeb thiab kev txawj ntse. Raws li ib tug graphite ingot tsum, kuv zoo siab los qhia rau koj cov ncauj lus kom ntxaws txheej txheem ntawm extruding graphite ingot.
Nkag siab Graphite Ingots
Graphite yog ib daim ntawv ntawm cov pa roj carbon uas muaj cov khoom tshwj xeeb xws li cov thermal conductivity, hluav taws xob conductivity, thiab tshuaj stability. Graphite ingots yog blocks ntawm graphite uas feem ntau siv nyob rau hauv ntau yam lag luam, xws li metallurgy, electronics, thiab aerospace. Qhov zoo ntawm graphite ingot nyob ntawm ntau yam, nrog rau cov purity ntawm graphite, qhov ntom, thiab cov qauv ntawm cov qauv.
Kev npaj cov khoom siv raw
Thawj kauj ruam hauv extruding graphite ingot yog los npaj cov khoom siv raw. High - zoo graphite hmoov yog cov khoom siv raw, thiab nws yuav tsum muaj qib siab purity. Cov impurities hauv graphite hmoov tuaj yeem cuam tshuam cov khoom ntawm qhov kawg ingot, yog li nws yog ib qho tseem ceeb uas yuav tau siv cov hmoov uas ua tau raws li qhov yuav tsum tau ua.
Ntxiv nrog rau cov graphite hmoov, kuj yuav tsum tau ib daim ntawv khi. Lub binder pab tuav cov graphite hais ua ke thaum lub sij hawm extrusion txheej txheem. Feem ntau siv binders muaj xws li pitch thiab resin. Tus nqi ntawm cov binder siv nyob ntawm seb hom graphite hmoov thiab cov khoom xav tau ntawm qhov kawg ingot.
Cov graphite hmoov thiab cov binder yog sib tov ua ke nyob rau hauv ib tug tov khoom los ua ib homogeneous sib tov. Cov txheej txheem sib xyaw no yog qhov tseem ceeb los xyuas kom meej tias cov binder sib npaug sib npaug thoob plaws hauv graphite hmoov. Cov sib tov yog ces preheated rau ib tug tshwj xeeb kub kom nws ntau malleable rau cov txheej txheem extrusion.
Extrusion txheej txheem
Thaum cov ntaub ntawv raw tau npaj, cov kauj ruam tom ntej yog txheej txheem extrusion. Lub preheated sib tov yog loaded rau hauv ib tug extruder. Lub extruder muaj ib lub thoob, ntsia hlau, thiab tuag. Cov ntsia hlau nyob rau hauv lub extruder tig thiab thawb cov khoom sib tov los ntawm lub thoob mus rau qhov tuag.
Cov tuag yog ib feem tseem ceeb ntawm cov txheej txheem extrusion. Nws muaj cov duab tshwj xeeb thiab qhov loj me uas txiav txim siab tus ntoo khaub lig -sectional profile ntawm graphite ingot. Piv txwv li, yog tias koj xav tsim ib lub cylindrical graphite ingot, qhov tuag yuav muaj lub voj voos -section. Cov tuag yog tsim los tiv thaiv kev kub ntxhov thiab kub, raws li cov txheej txheem extrusion yuav tsum siv lub zog tseem ceeb rau qhov sib tov.
Raws li qhov sib tov yog thawb los ntawm qhov tuag, nws yuav siv sij hawm ntawm cov duab ntawm qhov tuag. Lub siab siv thaum lub sij hawm extrusion txheej txheem pab kom compact cov graphite hais thiab tshem tawm tej huab cua npuas. This results in a dense and uniform structure of the graphite ingot.
Thaum lub sij hawm extrusion txheej txheem, nws yog ib qho tseem ceeb los tswj qhov kub thiab txias ntawm extruder. Qhov ntsuas kub cuam tshuam qhov viscosity ntawm qhov sib tov, thiab yog tias nws siab dhau lossis qis dhau, nws tuaj yeem cuam tshuam qhov zoo ntawm qhov kawg ingot. Qhov ceev ntawm lub extruder kuj plays lub luag hauj lwm nyob rau hauv kev txiav txim qhov ceev thiab lub uniformity ntawm lub ingot.
Ncej -Extrusion Processing
Tom qab cov graphite ingot yog extruded, nws tau dhau ob peb ncej-extrusion txheej txheem. Thawj kauj ruam yog ua kom txias. Lub extruded ingot yog txias maj mam mus rau chav sov kom tsis txhob tawg. Cov cua txias nrawm tuaj yeem ua rau muaj kev ntxhov siab sab hauv hauv cov khoom siv, uas tuaj yeem ua rau tawg thiab lwm yam tsis xws luag.
Thaum lub ingot txias, nws yog trimmed kom tshem tawm tej yam khoom tshaj. Qhov no ua kom ntseeg tau tias lub ingot muaj qhov tseeb qhov ntev thiab ua kom zoo nkauj. Tom qab ntawd lub trimmed ingot raug tshuaj xyuas rau tej yam tsis xws luag, xws li tawg, voids, los yog qhov chaw tsis sib xws.
Cov kauj ruam tom ntej yog kev kho cua sov. Kev kho cua sov yog siv los txhim kho cov khoom ntawm graphite ingot. Nws tuaj yeem ua kom qhov ntom ntom, hardness, thiab thermal conductivity ntawm ingot. Cov txheej txheem kev kho cua sov yuav tsum ua kom sov lub ingot mus rau qhov kub thiab txias thiab tuav nws ntawm qhov kub ntawm lub sijhawm, ua raws li qhov txias txias.
Kev Tswj Xyuas Zoo
Kev tswj kom zoo yog qhov tseem ceeb ntawm cov txheej txheem extrusion. Raws li tus neeg muag khoom graphite ingot, peb muaj kev tswj xyuas nruj zoo nyob rau hauv qhov chaw kom ntseeg tau tias txhua qhov ingot ua tau raws li cov qauv xav tau. Peb siv ntau txoj hauv kev los ntsuas cov khoom ntawm graphite ingot, suav nrog kev ntsuas qhov ntom ntom, ntsuas qhov tawv, thiab ntsuas thermal conductivity.
Kev ntsuas ntom ntom yog siv los ntsuas qhov loj ntawm ib chav tsev ntim ntawm qhov ingot. Ib qho kev ceev dua feem ntau qhia tau hais tias zoo dua ingot, raws li nws txhais tau hais tias cov graphite hais ntau nruj nreem ntim ua ke. Kev ntsuam xyuas hardness yog siv los txiav txim siab qhov tsis kam ntawm lub ingot rau indentation lossis khawb. Kev ntsuas thermal conductivity ntsuas seb lub ingot ua cua sov zoo npaum li cas.
Ntxiv nrog rau cov kev ntsuam xyuas ntawm lub cev no, peb kuj ua cov tshuaj ntsuam xyuas kom ntseeg tau tias lub ingot muaj cov tshuaj muaj pes tsawg leeg. Qhov no yuav pab kom paub tseeb tias lub ingot yog dawb los ntawm impurities thiab ua tau raws li cov qauv purity xav tau.
Kev siv ntawm Graphite Ingots
Graphite ingots muaj ntau yam kev siv hauv ntau yam lag luam. Hauv kev lag luam metallurgy, graphite ingots yog siv hauv Graphite Moulds rau Nruam Casting. Cov pwm no yog siv los ua cov hlau molten rau hauv cov ntaub ntawv tshwj xeeb thaum lub sij hawm nruam casting txheej txheem. Lub siab thermal conductivity thiab tshuaj stability ntawm graphite ua rau nws yog ib qho khoom zoo rau cov pwm no.
Hauv kev lag luam hniav nyiaj hniav kub, Graphite Mould rau Hnub Qub Ntawm David Kub yog siv los tsim cov hniav nyiaj hniav kub zoo nkauj. Lub precision thiab durability ntawm graphite pwm tso cai rau zus tau tej cov high - hniav nyiaj hniav kub zoo nrog cov ncauj lus kom ntxaws tsim.
Hauv kev lag luam hlau smelting, Graphite Degassing Rotor yog lwm daim ntawv thov tseem ceeb ntawm graphite ingots. Lub degassing rotor yog siv los tshem tawm hydrogen thiab lwm yam gases los ntawm molten hlau, txhim kho qhov zoo ntawm cov khoom hlau kawg.
