Furnace Frontiers: Siv 800℃Cartridge rhaub hauv Industrial thiab Laboratory Ovens

High - qhov cub kub, txawm tias ua haujlwm rau qhov kev xav tau ntawm kev kho cua sov hauv kev lag luam lossis cov kev xav tau ntawm cov kev sim ua kom pom tseeb, thov kom muaj cua sov uas tsis yog lub zog xwb tab sis kuj tseem ruaj khov thiab tswj tau. Cartridge rhaub, nrog nws daim ntawv cog lus cylindrical thiab muaj peev xwm xa cov cua sov hauv zos, yog lub ntuj thiab ntau yam haum rau cov ntawv thov no. Txawm li cas los xij, xaiv thiab siv lub tshuab ua kom sov rau lub cub tawg ntawm 800℃yuav tsum muaj qhov sib txawv ntawm engineering lub siab dua li nws siv ntau dua hauv cov pwm lossis cov cua sov platen. Lub thermal ib puag ncig feem ntau tsis tshua muaj kev txwv, kev hloov hluav taws xob cuam tshuam nrog kev sib cuam tshuam ntawm cov hluav taws xob hluav taws xob thiab kev sib txuas, thiab kev ua haujlwm xav tau ncua sij hawm los ntawm brute- quab yuam ua kom ntev mus rau qhov zoo tshaj plaws.

Lub Cev Muaj Hluav Taws Xob: Xav tau ntev ntev hauv ib puag ncig hnyav

Hauv cov chaw muaj kev lag luam-xws li cov hlau annealing, sintering ceramics, los yog cov cuab yeej hardening- furnaces ua hauj lwm nyob rau hauv ib tug tsis tu ncua, feem ntau rau txim. Qhov kub thiab txias tuaj yeem ua rau lub voj voog loj heev, muaj peev xwm ntawm 500℃mus rau 1200 degree, thiab cov cua tuaj yeem muaj cov hmoov av abrasive, nplai, lossis txawm tias me me corrosive gases los ntawm cov txheej txheem volatiles. Rau lub tshuab rhaub dej kub ua haujlwm tsis tu ncua ntawm 800℃cim nyob rau hauv cov ntsiab lus no, kev xaiv cov khoom siv yog qhov tseem ceeb rau kev ua neej ntev.

Cov ntaub qhwv sab nrauv yuav tsum tiv thaiv ob yam tseem ceeb: oxidation thiab mechanical degradation (creep) ntawm qhov kub thiab txias. Standard 304 stainless hlau, tsim nyog rau qis- daim ntawv thov kub, yuav ua kom nrawm thiab poob lub zog ntawm 800 degree, ua rau ua tsis tiav ntxov. Rau kev ua haujlwm ruaj khov, siab -kub alloys tsis yog- sib tham.Alloy 310S stainless hlauthiabIncoloy 800 HTFeem ntau tau teev tseg rau lawv cov kev tiv thaiv zoo tshaj plaws rau oxidation, carburization, thiab lawv cov khoom siv hluav taws xob khaws cia. Internally, cov hlau kuj yuav tsum tau upgraded. Thaum npib tsib xee-chrome (NiCr) alloys yog tus qauv, rau 800℃txog 1000℃ntau,hlau -chromium- txhuas (FeCrAl) alloysfeem ntau nyiam. Lawv muaj kev tiv thaiv ntau dua (tso cai rau ntau lub kauj nyob rau hauv qhov chaw muab), oxidation kuj zoo heev vim yog tsim cov txheej txheem alumina tiv thaiv, thiab kev tiv thaiv zoo tshaj rau sagging lossis "ceep" dhau sijhawm. Tsis tas li ntawd, nyob rau hauv cov high - cua sov, siab - vibration industrial settings, kev tsim kho sab hauv-tshwj xeeb yog qhov ntom ntom ntawm magnesium oxide (MgO) rwb thaiv tsev- yuav tsum tau ua kom siab tshaj plaws los ntawm kev swaging kom ntseeg tau tias cov cua sov hloov pauv tau zoo thiab tiv thaiv cov coil txav uas tuaj yeem ua rau hotspots thiab tsis ua haujlwm.

Lub Cev Hluav Taws Xob: Precision, Purity, thiab Tswj Cov Cuab Yeej

Laboratory furnaces, siv nyob rau hauv kev tshawb fawb, kev tswj kom zoo, thiab kev txhim kho cov ntaub ntawv siab heev, nthuav qhia qhov sib txawv ntawm cov teeb meem. Ntawm no, qhov tseem ceeb hloov mus rau qhov kub tsis sib xws, kev tswj xyuas qhov tseeb (feem ntau nyob rau hauv ± 1 degree), thermal cycling ceev, thiab txheej txheem purity. Lub tshuab cua sov cartridge hauv qhov teeb tsa no yog qhov ntsuas ntsuas qhov tseeb.

Kev ruaj ntseg hluav taws xob tsis zoo yog qhov tseem ceeb rau kev tswj kom raug- voj voog ua haujlwm. Qhov no yuav tsum tau siv high-purity, zoo ib yam- qib tsis kam xaim thiab cov txheej txheem tsim khoom zoo. Txhawm rau kom ua tiav qhov ntsuas kub xav tau thiab txo qis thermal lag lossis overshoot, cov cua sov feem ntau ua haujlwm ntawm alow nto load (watt ceev), feem ntau nruab nrab ntawm1.0 thiab 2.5 W / cm². Qhov no "mos" cua sov kom ntseeg tau tias cov cua sov yog tsim los ntawm tus nqi ntawm lub tshuab hluav taws xob rwb thaiv tsev thiab kev tswj xyuas muaj peev xwm tswj tau tusyees, tiv thaiv cov chaw kub kub ntawm lub plhaub. Cov cua sov feem ntau yog npaj rau hauv ib cheeb tsam raws cov phab ntsa ntawm lub cub tawg lossis hauv cov rwb thaiv tsev kom tsim tau ib qho chaw kub kub.

Atmospheric kev txiav txim siab ntxiv nyuaj rau kev xaiv. Yog tias lub cub tawg ua haujlwm raws li alub tshuab nqus tsev, txheem sheath cov ntaub ntawv yuav undergo sublimation, kis tus txheej txheem. Nyob rau hauv xws li mob, refractory hlau nyiammolybdenumlos yogtungstenyuav tsum tau, txawm tias lawv brittleness thiab oxidation rhiab heev nyob rau hauv huab cua thov ceev faj tuav. Rau inert lossis txo cov cua sov (xws li argon, hydrogen, tsim cov pa), oxidation tsis kam ntawm sheath yog qhov tseem ceeb tsawg, tab sis cov khoom sib raug zoo nrog cov roj yog qhov tseem ceeb. Qhov tseem ceeb, lubMgO rwb thaiv tsev hmoov yuav tsum yog siab -purity, "volatile- dawb" qibtxhawm rau tiv thaiv kev tawm ntawm cov kab mob uas tuaj yeem cuam tshuam cov kev sim rhiab, xws li hauv kev loj hlob siv lead ua lossis kev ua semiconductor.

Tsim kev koom ua ke: Los ntawm Cheeb Tsam mus rau System

Kev ua tiav ntawm kev siv lub tshuab cua sov hauv cov tshuab hluav taws xob txuas ntxiv mus dhau lub rhaub nws tus kheej. Nws muaj kev xav txog kev sib koom ua ke. Hauv kev lag luam kilns, lawv tuaj yeem muab tso rau hauv cov khoom siv tiv thaiv ceramic lossis hlau hlau (sockets) hauv phab ntsa ntawm lub qhov cub. Nyob rau hauv lab tube furnaces, lawv yog precisely positioned nyob ib ncig ntawm lub hauv paus ua hauj lwm raj. Cov kev sib txuas hluav taws xob thiab kev pub khoom noj yuav tsum raug ntsuas rau qhov ntsuas kub sab nraud thiab lub qhov cub ua haujlwm. Thermal expansion yuav tsum haum rau hauv lub tshuab tsim los tiv thaiv kev ntxhov siab tawg.

Nyob rau hauv xaus, lub cartridge rhaub ua pov thawj los ua ib tug zoo kawg li adaptable daws nyob rau hauv lub furnace frontier. Nws cov nqi hluav taws xob nthuav tawm los ntawm cov rugged, siab -watt- qhov xav tau ceev ntawm lub qhov cub hardening rau qhov qis -watt- ntom, ultra- huv qhov xav tau ntawm lub tshuab nqus tsev tshawb fawb cub. Tus yuam sij rau kev qhib qhov kev sib tw no yog nyob rau hauv kev txav mus dhau qhov kev qhia dav dav. Nws yuav tsum muaj cov txheej txheem-theem mus kom ze uas ua tib zoo ua raws lub rhaub cov ntsiab lus tshwj xeeb- sheath alloy, tiv thaiv hlau muaj pes tsawg leeg, watt ntom, thiab kev tsim kho sab hauv-nrog rau cov thermal, atmospheric, thiab tswj kev xav tau ntawm lub tshuab ua hluav taws xob. Thaum qhov kev sib raug zoo no ua tiav, lub tshuab hluav taws xob cartridge hloov los ntawm cov khoom siv yooj yim rau hauv kev ntseeg siab, siab -kev ua haujlwm thermal.
