Kev siv tseem ceeb ntawm cov khoom graphite
Cov khoom siv graphite tuaj yeem tso tawm cov duab infrared deb tom qab cua sov.
Cib magnesium-carbon Magnesium-carbon refractory yog nruab nrab ntawm lub sijhawm, tsim los ntawm Tebchaws Meskas, kev lag luam hlau Nyiv pib siv cib magnesium-carbon rau dej txias arc cub tawg smelting. Magnesia-carbon cib tau siv dav hauv kev ua hlau thoob ntiaj teb thiab tau dhau los ua kev siv graphite ib txwm muaj. Thaum pib ntawm lub xyoo caum, magnesium-carbon cib tau pib siv rau hauv daim ntaub ntawm cov pa oxygen top-blown converter.
Cov khoom siv refractory aluminium carbon cib aluminium carbon feem ntau yog siv rau hauv kev sib txuas ntxiv casting, cov hlau tiaj tiaj billet tus kheej tso rau hauv cov kav dej fort, lub nozzle hauv qab dej thiab lub tog raj kheej roj qhov dej blasting. Cov hlau tsim los ntawm kev sib txuas ntxiv casting hauv Nyiv Pooj suav ntau dua li tag nrho cov khoom tsim tawm.
Crucible thiab cov khoom lag luam cuam tshuam ua los ntawm graphite molding thiab refractory crucible thiab cov khoom lag luam cuam tshuam, xws li crucible, lub raj mis caj dab nkhaus, ntsaws thiab nozzle, thiab lwm yam, muaj kev tiv thaiv hluav taws kub, tsis tshua muaj thermal nthuav dav, yaj hlau txheej txheem, los ntawm hlau infiltration thiab erosion kuj ruaj khov, zoo thermal shock stability ntawm qhov kub siab thiab zoo heev conductivity. Yog li ntawd, graphite crucible thiab nws cov khoom cuam tshuam yog dav siv hauv cov txheej txheem ntawm kev yaj ncaj qha ntawm cov hlau. Cov av nplaum graphite ib txwm muaj cov ntsiab lus carbon ntau dua li qhov ntsuas graphite, feem ntau qhov ntsuas graphite yuav tsum loj dua li lub mesh (- screen), thiab qhov kev txhim kho tseem ceeb hauv kev tsim khoom txawv teb chaws crucible yog tias hom graphite siv, qhov loj me thiab zoo muaj kev ywj pheej ntau dua ua raws li kev siv silicon carbide graphite crucible es tsis txhob siv cov av nplaum graphite crucible ib txwm muaj. Qhov no yog vim muaj kev qhia txog cov thev naus laus zis siab tas li hauv kev lag luam steelmaking. Kev siv cov thev naus laus zis siab tas li kuj tuaj yeem ua rau me me graphite tuaj yeem siv, hauv av nplaum graphite crucible, thiab hauv silicon carbide graphite crucible, cov ntsiab lus ntawm cov khoom loj tsuas yog suav rau, thiab cov ntsiab lus carbon ntawm graphite raug txo kom.
kev ua hlau
Graphite thiab lwm yam khoom tsis huv siv tau ua carburizers hauv kev lag luam hlau. Carburizing siv ntau yam khoom siv carbonaceous, suav nrog graphite dag, roj av coke, metallurgical coke thiab graphite ntuj. Graphite tseem yog ib qho ntawm kev siv tseem ceeb ntawm graphite zoo li lub ntiaj teb hauv ntiaj teb.
Cov khoom siv hluav taws xob
Graphite siv dav hauv kev lag luam hluav taws xob ua electrodes, txhuam, carbon rods, carbon tubes, mercury rectifiers, graphite gaskets, xov tooj, TV duab raj txheej thiab lwm yam. Ntawm lawv, graphite electrode yog qhov siv dav tshaj plaws, hauv kev smelting ntawm ntau yam hlau alloy, hlau alloy, siv graphite electrode, tom qab ntawd muaj zog tam sim no los ntawm electrode mus rau hauv lub cub tawg melting cheeb tsam, tsim ib qho arc, yog li lub zog hluav taws xob mus rau hauv lub zog cua sov, qhov kub nce mus txog li, kom ua tiav lub hom phiaj ntawm kev yaj lossis kev ua haujlwm. Tsis tas li ntawd, thaum electrolyzing magnesium, txhuas thiab sodium, lub anode ntawm electrolytic cell kuj siv graphite electrode. Graphite electrode kuj siv ua cov khoom siv conductive ntawm lub taub hau cub rau kev tsim cov abrasive tiv thaiv furnaces. Graphite siv hauv kev lag luam hluav taws xob muaj qhov yuav tsum tau siab rau qhov loj me ntawm cov khoom me me thiab qib. Xws li alkaline roj teeb thiab qee cov khoom siv hluav taws xob carbon tshwj xeeb, qhov loj me ntawm graphite particle yuav tsum tau tswj hwm hauv qhov project, qib yog siab dua, thiab cov khoom tsis zoo (feem ntau yog hlau hlau) yuav tsum tau qis dua. Graphite siv hauv TV duab raj muaj cov qhov yuav tsum tau ua hauv qab no. Graphite feem ntau siv ua roj nplua nyeem hauv kev lag luam tshuab. Cov roj nplua nyeem feem ntau siv tsis tau rau hauv qhov ceev ceev, kub siab, thiab siab, thiab cov khoom siv graphite uas tsis yooj yim hnav tuaj yeem ua haujlwm yam tsis muaj roj nplua nyeem ntawm - kub thiab ntawm qhov ceev ceev heev. Ntau yam khoom siv thauj khoom corrosive, cov khoom siv graphite dav siv ua los ntawm piston rings, seals thiab bearings, thaum lawv khiav, tsis tas yuav ntxiv roj nplua nyeem, mis graphite kuj yog cov roj nplua nyeem zoo rau ntau yam kev ua hlau (hlau kos duab, raj kos duab).
Cov khoom siv tiv taus xeb
Graphite muaj kev ruaj khov tshuaj zoo. Graphite ua tshwj xeeb muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, zoo thermal conductivity thiab qis permeability, thiab yog dav siv rau hauv kev tsim cov cua sov exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, pumps thiab lwm yam khoom siv. Cov khoom siv no yog siv rau hauv petrochemical, hydrometallurgy, acid thiab alkali ntau lawm, synthetic fiber, paper thiab lwm yam kev lag luam, tuaj yeem txuag tau ntau yam khoom siv hlau. 0 Rau casting, sanding, pressing thiab high-temperature metallurgical cov ntaub ntawv vim yog qhov me me expansion coefficient ntawm graphite, thiab muaj peev xwm hloov txias thiab cua sov, tuaj yeem siv ua iav pwm, tom qab siv graphite, cov hlau dub castings tau txais qhov loj me, du nto, siab yield, tuaj yeem siv yam tsis tau ua tiav lossis me ntsis ua tiav, yog li txuag tau ntau yam hlau. Kev tsim cov carbide thiab lwm yam hmoov metallurgy txheej txheem, feem ntau yog ua los ntawm graphite cov ntaub ntawv rau kev tiv thaiv siab rau sintering ntawm nkoj. Monocrystalline silicon crystal growth crucible, regional refining vessel, bracket, fixture, induction heater, thiab lwm yam, yog ua tiav nrog high purity graphite. Tsis tas li ntawd xwb, graphite kuj siv tau ua lub phaj thiab lub hauv paus rwb thaiv tsev graphite nqus tsev metallurgy, lub raj cua sov kub, pas nrig, phaj, daim phiaj thiab lwm yam khoom.
Lub zog atomic
Graphite muaj kev ua tau zoo ntawm kev txo qis neutron, thawj zaug siv ua tus moderator hauv atomic reactors, uranium-graphite reactor yog ib qho atomic reactor siv dav dua. Ua lub zog rau atomic zog reactor deceleration cov khoom siv yuav tsum muaj qhov melting point siab, ruaj khov, tiv taus corrosion, graphite tuaj yeem ua tau raws li cov kev cai saum toj no. Qhov purity ntawm graphite siv ua atomic reactor siab heev, thiab cov ntsiab lus impurity yuav tsum tsis pub tshaj kaum ob (ib feem ib lab), tshwj xeeb tshaj yog cov ntsiab lus ntawm boron yuav tsum tsawg dua.
Cov khoom siv tiv thaiv kev laus thiab tiv thaiv xeb
Cov kev sim ntsuas qhia tau tias kev ntxiv qee yam hmoov graphite rau hauv dej (kwv yees li ib tuj dej) tuaj yeem tiv thaiv kev ua kom tsis txhob muaj nplai ntawm qhov chaw ntawm lub boiler. Tsis tas li ntawd, graphite siv rau cov qhov cub hlau, cov ru tsev, cov choj, thiab cov kav dej tuaj yeem tiv thaiv xeb thiab tiv thaiv xeb.
Lwm yam kev siv
Nrog rau kev txhim kho tas mus li ntawm kev tshawb fawb thiab thev naus laus zis, tib neeg tau tsim ntau yam kev siv tshiab rau graphite. Cov khoom siv graphite uas yooj ywm. Graphite uas yooj ywm, tseem hu ua graphite nthuav dav, yog cov khoom siv graphite tshiab uas tau tsim nyob rau xyoo 1990. Tebchaws Meskas tau ua tiav kev tshawb fawb txog cov khoom siv sealing graphite uas yooj ywm los daws qhov teeb meem xau ntawm cov atomic energy valves, thiab tom qab ntawd lub tebchaws Yelemees, Nyiv Pooj thiab Fabkis kuj tau pib tsim thiab tsim khoom. Ntxiv nrog rau cov yam ntxwv ntawm graphite ntuj, cov khoom no muaj kev ywj pheej tshwj xeeb thiab elasticity. Yog li ntawd, nws yog cov khoom siv sealing zoo tagnrho. Siv dav hauv petrochemical, atomic energy thiab lwm yam kev lag luam. Kev thov kev lag luam thoob ntiaj teb tau nce ntxiv txhua xyoo.
Cov khoom siv purity siab yog siv rau hauv kev smelting hlau purity siab, kev lag luam electronics, kev lag luam nuclear thiab kev tsim pwm; Cov khoom siv dav dav yog siv rau hauv lub tank electrolysis txhuas, hmoov metallurgy sintering rauv, ferroalloy rauv thiab lwm yam khoom siv rauv masonry.
