Graphite ingots, ib daim ntawv ntawm siab - purity graphite, tau tshwm sim los ua ib qho khoom tseem ceeb hauv kev lag luam tshuaj. Raws li ib tug txhim khu kev qha graphite ingot tsum, kuv yog zoo - versed nyob rau hauv lub ntau yam kev siv ntawm cov ingots, uas yog sib sib zog nqus rooted nyob rau hauv cov yam ntxwv ntawm graphite.
Ib qho ntawm cov kev siv tseem ceeb tshaj plaws ntawm graphite ingots hauv kev lag luam tshuaj yog lawv siv hauv kev tsim cov Foundry Graphite Crucibles. Graphite crucibles yog cov thawv uas siv rau melting thiab tuav cov hlau molten thiab lwm yam khoom ntawm qhov kub thiab txias. Lub siab thermal conductivity thiab zoo heev kub tsis kam ntawm graphite ingots ua rau lawv zoo tagnrho rau lub hom phiaj no. Thaum cov graphite ingots tau ua tiav rau hauv crucibles, lawv tuaj yeem tiv taus qhov kub thiab txias uas yuav tsum tau ua rau cov hlau melting xws li txhuas, tooj liab, thiab cov hlau zoo nkauj. Piv txwv li, nyob rau hauv kev tsim cov txhuas alloys, graphite crucibles ua los ntawm siab - zoo graphite ingots tuaj yeem tswj lawv cov qauv kev ncaj ncees txawm tias kub tshaj 1000 ° C. Qhov no tso cai rau cov txheej txheem melting zoo thiab meej, ua kom cov khoom zoo ntawm cov khoom hlau kawg.
Graphite ingots kuj ua lub luag haujlwm tseem ceeb hauv kev tsim cov Pure Graphite Ingot Pwm. Cov pwm no yog siv los ua cov hlau molten rau hauv cov khoom ntawm qhov ntau thiab tsawg thiab cov duab. Qhov qis coefficient ntawm thermal expansion ntawm graphite kom ntseeg tau tias cov pwm tsis tawg los yog deform thaum lub sij hawm cua kub ceev thiab txias cycles txuam nrog hlau casting. Ntxiv mus, graphite tsis yog - reactive xwm nrog feem ntau molten hlau tiv thaiv kev kis kab mob ntawm cov ingots. Hauv kev lag luam tshuaj, qhov chaw purity ntawm cov hlau yog qhov tseem ceeb tshaj plaws, graphite ingot pwm yog qhov tseem ceeb rau kev tsim cov khoom siab - purity hlau ingots. Piv txwv li, hauv kev tsim cov khoom siv hluav taws xob - qib tooj liab, kev siv cov graphite ingot pwm pab tswj kom muaj cov purity siab ntawm tooj liab, uas yog qhov tseem ceeb rau nws daim ntawv thov hauv cov khoom siv hluav taws xob.
Lwm daim ntawv thov tseem ceeb yog nyob rau hauv daim ntawv ntawm Graphite Degassing Rotor. Hauv kev lag luam tshuaj thiab hlau - kev lag luam, qhov muaj roj nyob hauv cov hlau molten tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg. Graphite degassing rotors yog siv los tshem tawm cov pa tsis xav tau los ntawm cov hlau molten. Lub zog siab thiab tshuaj lom neeg ruaj khov ntawm graphite ingots ua rau lawv tsim nyog rau kev tsim cov rotors. Thaum lub rotor tig nyob rau hauv cov hlau molten, nws tsim ib lub tshuab nqus tsev nyhuv uas rub tawm cov yaj gases. Cov txheej txheem no txhim kho cov khoom siv kho tshuab thiab zoo ntawm cov khoom siv hlau kawg. Piv txwv li, nyob rau hauv zus tau tej cov siab - lub zog aluminium alloys rau aerospace daim ntaub ntawv, kev siv graphite degassing rotors pab txo porosity thiab txhim kho tag nrho lub zog thiab durability ntawm cov alloys.
Ntxiv nrog rau cov hlau - cov ntaub ntawv ntsig txog, graphite ingots yog siv los tsim ntau yam tshuaj catalysts. Graphite tuaj yeem ua raws li cov khoom siv txhawb nqa rau cov catalysts vim nws qhov chaw loj thiab muaj peev xwm adsorption siab. Catalysts txhawb nqa ntawm graphite tuaj yeem txhim kho qhov ua tau zoo ntawm cov tshuaj tiv thaiv tshuaj lom neeg los ntawm kev muab ntau qhov chaw ua haujlwm rau cov reactants. Piv txwv li, hauv kev lag luam petrochemical, graphite - txhawb nqa catalysts yog siv rau hauv cov txheej txheem xws li hydrocracking thiab hloov kho. Cov txheej txheem no tseem ceeb heev rau kev hloov cov hydrocarbons hnyav rau hauv cov khoom sib dua, muaj txiaj ntsig ntau dua. Kev ruaj ntseg ntawm graphite nyob rau hauv hnyav tshuaj thiab thermal tej yam kev mob ua rau nws yog ib qho zoo tagnrho cov ntaub ntawv txhawb rau cov catalysts, kom ntseeg tau ntev - lub sij hawm kev ua tau zoo thiab siab catalytic.
Graphite ingots kuj tseem siv rau hauv kev tsim cov electrodes rau cov txheej txheem electrochemical. Hauv kev lag luam xws li electroplating thiab electrolysis, siab - cov electrodes zoo yuav tsum tau ua kom ntseeg tau tias muaj txiaj ntsig zoo thiab sib xws ntawm cov hlau. Graphite electrodes ua los ntawm graphite ingots muaj hluav taws xob conductivity thiab tshuaj tiv thaiv. Lawv tuaj yeem tiv taus qhov corrosive ib puag ncig ntawm electrolytes thiab muab cov hluav taws xob ruaj khov thaum lub sij hawm electrochemical txheej txheem. Piv txwv li, nyob rau hauv electroplating ntawm cov hniav zoo nkauj thiab haumxeeb txheej ntawm cov hlau nto, graphite electrodes pab kom ua tiav ib tug du thiab zoo txheej txheej, txhim kho cov tsos thiab kev ua tau zoo ntawm cov khoom coated.
Hauv kev khaws tshuaj thiab kev thauj mus los, graphite ingots yog siv los tsim cov khoom tiv thaiv corrosion -. Graphite tsis kam rau ntau yam tshuaj, nrog rau cov kua qaub, alkalis, thiab cov kuab tshuaj organic, ua rau nws tsim nyog siv rau hauv cov tso tsheb hlau luam, cov kav dej, thiab cov li qub. Cov khoom no tuaj yeem khaws cia thiab thauj cov tshuaj corrosive yam tsis muaj kev puas tsuaj. Piv txwv li, nyob rau hauv kev lag luam tshuaj, qhov loj - scale cia ntawm sulfuric acid yog yuav tsum tau, graphite - lined cia tso tsheb hlau luam muab ib tug txhim khu kev qha thiab ntev - kev daws teeb meem.
Kev siv graphite ingots hauv kev lag luam tshuaj kuj tseem txuas ntxiv mus rau kev tsim cov khoom siv hluav taws xob. Graphite lub siab thermal conductivity thiab tshuaj tiv thaiv ua rau nws yog ib qho khoom siv zoo heev rau kev siv cua sov. Graphite heat exchangers tuaj yeem hloov cov cua sov kom zoo ntawm cov kua tshuaj sib txawv yam tsis tau corroded los ntawm cov kua. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov txheej txheem tshuaj lom neeg uas yuav tsum tau tswj qhov kub thiab txias. Piv txwv li, nyob rau hauv kev tsim cov tshuaj chemical, graphite tshav kub exchangers yog siv los tswj cov tshuaj tiv thaiv kub nyob rau hauv ib tug tshwj xeeb ntau yam, kom ntseeg tau qhov zoo thiab yield ntawm cov khoom kawg.
