Thaum nws los txog rau lub ntiaj teb ntawm cov hlau smelting, graphite stopper yog ib qho khoom siv tsis tau. Raws li tus neeg muag khoom ntawm graphite stoppers, kuv tau muaj cai ua haujlwm nrog ntau tus neeg siv khoom, nkag siab txog lawv cov kev xav tau, thiab ua pov thawj ntawm lub luag haujlwm tseem ceeb ntawm cov khoom no ua si hauv cov hlau - txheej txheem smelting. Hauv blog no, kuv mam li qhia cov ntsiab lus tseem ceeb uas koj yuav tsum xav txog thaum yuav ib lub graphite stopper.
1. Purity ntawm Graphite
Lub purity ntawm graphite nyob rau hauv ib tug graphite stopper yog qhov tseem ceeb tshaj plaws. Siab - purity graphite muaj cov tshuaj zoo dua qub thiab thermal kuj. Hauv cov hlau - smelting ib puag ncig, qhov kub tuaj yeem ncav cuag qib siab heev thiab muaj ntau yam tshuaj lom neeg tshwm sim, ib qho chaw nres tsheb ua los ntawm siab - purity graphite tsis tshua muaj tshwm sim nrog cov hlau molten lossis lwm yam khoom hauv lub cub tawg.
Cov impurities nyob rau hauv graphite tuaj yeem ua rau ua rau ntxov ntxov degradation ntawm stopper. Piv txwv li, sulfur thiab phosphorus impurities tuaj yeem ua rau corrosion thiab embrittlement, txo lub neej ntawm lub stopper. Thaum xaiv graphite stopper, nrhiav cov khoom uas muaj graphite purity tsawg kawg yog 99%. Qhov siab - purity graphite no ua kom lub neej ua haujlwm ntev dua thiab txhim khu kev qha ntau dua thaum lub sijhawm smelting.
2. Ceev thiab Porosity
Qhov ntom thiab porosity ntawm graphite stopper yog ze ze rau nws cov neeg kho tshuab lub zog thiab permeability. Qhov siab dua - graphite stopper feem ntau muaj cov khoom siv zoo dua qub, uas txhais tau hais tias nws tuaj yeem tiv taus cov neeg kho tshuab kev ntxhov siab thaum lub sijhawm ua haujlwm, xws li lub siab los ntawm cov hlau molten thiab lub zog siv thaum lub sijhawm qhib thiab kaw ntawm lub stopper.
Ntawm qhov tod tes, porosity cuam tshuam rau lub stopper lub peev xwm los tiv thaiv cov to ntawm molten hlau. Lub stopper uas tsis tshua muaj porosity tuaj yeem thaiv qhov ntws ntawm cov hlau molten, ua kom cov txheej txheem smelting ntau dua thiab muaj txiaj ntsig zoo. Txawm li cas los xij, nws yog ib qho tseem ceeb rau kev sib npaug. Qee theem ntawm kev tswj porosity tuaj yeem ua tau zoo rau kev tso tawm cov pa roj carbon monoxide generated thaum smelting.
3. Thermal conductivity
Thermal conductivity yog ib qho tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv siab - kub hlau - smelting txheej txheem. Lub graphite stopper nrog zoo thermal conductivity tuaj yeem hloov cov cua sov sai sai, uas yuav pab tswj kom muaj qhov sib txawv ntawm qhov kub thiab txias hauv qhov cub. Qhov no yog ib qho tseem ceeb rau kev ua kom zoo ib yam ntawm cov hlau molten thiab tiv thaiv cov cua sov hauv zos uas tuaj yeem ua rau cov khoom tawg lossis lwm yam khoom hauv lub cub tawg.
Siab - thermal - conductivity graphite stoppers kuj tseem tuaj yeem teb sai dua rau kev hloov pauv kub thaum lub sij hawm smelting txheej txheem, tso cai rau kev tswj kom zoo dua ntawm cov hlau - pouring lag luam. Thaum xaiv ib lub graphite stopper, xav txog cov kev cai thermal tshwj xeeb ntawm koj cov txheej txheem smelting thiab xaiv ib lub stopper uas tsim nyog thermal conductivity.
4. Cov duab thiab qhov loj me
Cov duab thiab qhov loj ntawm graphite stopper yuav tsum tau ua kom haum rau koj cov khoom siv smelting. Lub qhov dej - haum stopper yog qhov tseem ceeb rau kev foob kom raug thiab ua haujlwm tau zoo. Lub stopper yuav tsum phim qhov ntev ntawm lub ladle lossis qhov cub qhib qhov twg nws yuav siv.
Ntxiv nrog rau qhov yuav tsum tau loj me me, cov duab ntawm lub stopper tuaj yeem cuam tshuam nws qhov kev ua tau zoo. Piv txwv li, qee daim ntawv thov yuav xav tau lub kaw lus kaw kom nruj kom haum thiab tiv thaiv kom tsis txhob tawm. Lwm tus yuav xav tau ib lub stopper nrog ib qho profile tshwj xeeb los pab txhawb kev ntws ntawm cov hlau molten hauv ib txoj kev. Ib txwm muab cov lus qhia meej meej rau koj tus neeg muag khoom kom ntseeg tau tias koj tau txais graphite stopper uas ua tau raws li koj xav tau.
5. Machining Zoo
Lub machining zoo ntawm graphite stopper yog lwm qhov tseem ceeb rau kev txiav txim siab. Lub qhov dej - machined stopper yuav muaj du nto thiab meej qhov ntev. Cov chaw ntxhib tuaj yeem ua rau muaj kev sib txhuam thaum lub sijhawm ua haujlwm, ua rau nws nyuaj rau qhib thiab kaw lub stopper smoothly. Qhov tsis raug qhov ntev tuaj yeem ua rau tsis zoo sealing thiab to ntawm cov hlau molten.
High - machining zoo kuj ua kom ntseeg tau tias lub stopper muaj cov khoom zoo ib yam thoob plaws hauv nws cov qauv. Qhov no yog qhov tseem ceeb rau kev tswj hwm nws cov kev ua tau zoo dhau sijhawm. Thaum ntsuam xyuas lub graphite stopper, xyuam xim rau qhov nto tiav thiab tag nrho cov precision ntawm machining.
6. Tshuaj tiv thaiv
Hauv cov hlau - smelting txheej txheem, cov graphite stopper raug rau ntau yam tshuaj, xws li molten hlau, fluxes, thiab slag. Yog li ntawd, nws yuav tsum muaj tshuaj tiv thaiv zoo heev. Lub stopper uas tuaj yeem tiv thaiv corrosion thiab tshuaj tua kab mob yuav muaj lub neej ntev kev pab cuam thiab tswj nws cov kev ua tau zoo nyob rau hauv cov xwm txheej hnyav.
Cov tshuaj tiv thaiv ntawm graphite stopper nyob ntawm qhov purity ntawm graphite thiab lwm yam txheej txheej lossis kev kho mob ntxiv. Qee cov graphite stoppers raug kho nrog cov txheej tshwj xeeb los txhim kho lawv cov tshuaj tiv thaiv. Xav txog cov tshuaj ib puag ncig tshwj xeeb ntawm koj cov txheej txheem smelting thiab xaiv ib lub stopper uas tsim los tiv thaiv cov xwm txheej.
7. Tus nqi - kev ua tau zoo
Thaum qhov zoo yog qhov tseem ceeb, tus nqi - kev ua tau zoo kuj yog qhov tseem ceeb thaum yuav lub graphite stopper. Koj yuav tsum sib npaug tus nqi pib ntawm lub stopper nrog nws cov kev pab cuam lub neej thiab kev ua tau zoo. Ib qho pheej yig dua stopper yuav zoo li qhov pib zoo, tab sis yog tias nws muaj lub neej luv luv lossis kev ua haujlwm tsis zoo, nws tuaj yeem ua rau koj raug nqi ntau dua nyob rau lub sijhawm ntev vim muaj kev hloov ntau zaus thiab muaj peev xwm cuam tshuam ntau lawm.
Ntawm qhov tod tes, ib qho khoom siv kim heev yuav tsis tas li muab qhov sib npaug ntawm qhov ua tau zoo. Ua haujlwm nrog koj tus neeg muag khoom kom nrhiav tau graphite stopper uas muaj kev sib xyaw ua ke zoo tshaj plaws thiab tus nqi rau koj daim ntawv thov tshwj xeeb.
8. Cov khoom lag luam muaj npe
Lub koob npe nrov ntawm tus neeg muag khoom yog qhov feem ntau - saib tsis taus tab sis tseem ceeb heev. Ib tus neeg muag khoom ntseeg siab yuav tsis tsuas yog muab siab - zoo graphite stoppers tab sis kuj muab kev pabcuam zoo rau cov neeg siv khoom thiab kev txhawb nqa.
