High-kub muaj qhov cub (600℃-800 degree)- siv rau kev kho cua sov hlau, ceramic sintering, thiab iav annealing- ntsib cov teeb meem loj xws li cov khoom oxidation, thermal qaug zog, thiab qhov kub tsis sib xws. Cov khoom cua kub ib txwm (xws li, cov coils tsis kam) degrade sai hauv cov xwm txheej no, ua rau kev hloov pauv txhua hli thiab kev tsim khoom poob qis. Hauv kev xyaum, cartridge rhaub [cartridge rhaub] ua rau ultra- kub kub daws cov teeb meem no nrog Inconel alloy casings, siab -emissivity nto, thiab robust nyob rau hauv kev tsim kho, ua rau lawv cov kev xaiv zoo tshaj plaws rau siab - cua kub cua sov.
Cartridge heaters [cartridge heater] rau siab -kub rauv siv Inconel 600/625 casings, uas tswj cov txheej txheem kev ncaj ncees thiab oxidation tsis kam ntawm 800℃- deb tshaj 316L stainless hlau qhov 600℃txwv. Cov xaim cua sov yog ua los ntawm siab-purity NiCrAl alloy (Cr20Ni80) nrog rau kev nkag siab{11}} tiv thaiv winding tsim, tiv thaiv kev tawg ntawm thermal expansion cycles. Raws li cov ntaub ntawv hauv teb, cov ntsiab lus no kav ntev li 8,{14}} teev hauv kev ua haujlwm tas li 700 degree-3x ntev dua li cov qauv cua sov. Lub siab -emissivity dub oxide txheej (emissivity 0.9) ua kom 85% ntawm cov hluav taws xob tsim hluav taws xob raug xa mus los ntawm hluav taws xob, tib txoj kev siv tau zoo nyob rau hauv qhov chaw qis cua sov.
Power density and installation layout are critical for high-temperature performance. Rau cov hlau annealing (600℃-700 degree), lub zog ceev ntawm 30-40 W / cm² muab cov cua sov ceev- nce thaum tsis txhob muaj kev ntxhov siab. Rau ceramic sintering (700℃-800 degree), 40-50 W / cm² yog siv nrog cov ntaub thaiv npog rau cov hluav taws xob ncaj qha rau cov khoom ua haujlwm. Txhim kho lub tshuab cua sov rau hauv cov kab ntsug raws cov phab ntsa rauv-nrog rau qhov sib nrug ntawm 20–25 cm{16}} tshem tawm qhov kub thiab txias, ua kom qhov kub thiab txias tsis pub dhau ± 4 degree. Qhov no ua kom ntseeg tau zoo ib yam nyuaj hauv cov cua sov{19}}kho cov hlau lossis cov khoom sib xws hauv cov sintered ceramics. Tus qauv tsim ib zaug - xaus tso cai rau kev hloov pauv yooj yim los ntawm lub tshuab hluav taws xob sab nrauv, txo lub sijhawm poob ntawm 8 teev (rau kev hloov coil) mus rau 1 teev.
Kev tswj cov cua kub thiab kev tiv thaiv tsis yog - sib tham hauv siab - qhov cub kub. Cartridge rhaub yog ua ke nrog K-hom thermocouples embedded nyob rau hauv lub ntsiab lus, muab tiag tiag -lub sij hawm kub tawm tswv yim rau lub cub tawg lub PLC. Overheat tiv thaiv tshuab txiav fais fab yog tias cov khoom nto tshaj 820 degree, tiv thaiv kev puas tsuaj mus tas li. Raws li kev paub dhau los, ntxiv cov txheej txheem ceramic fiber ntau rwb thaiv tsev nyob ib ncig ntawm lub tshuab cua sov array txo cov cua sov ntawm lub qhov cub sab nrauv los ntawm 40%, txo cov nqi zog. Kev saib xyuas tsis tu ncua- tshuaj xyuas cov kab nrib pleb txhua 3 lub hlis thiab ntxuav qhov chaw oxide tsim nrog cov txhuam hlau- txuas ntxiv lub neej los ntawm 2,000 teev ntxiv.
Nyob rau hauv cov ntsiab lus, cartridge heaters [cartridge heater] yog cov khoom siv hluav taws xob uas txhim khu kev qha tshaj plaws rau siab -kub muaj qhov cub, muab qhov tsis sib xws, kev ua haujlwm hluav taws xob, thiab qhov kub thiab txias. Txhawm rau kom tsis txhob muaj qhov tsis ua haujlwm ntau zaus thiab cov khoom ua haujlwm tsis zoo, xaiv Inconel-cased heaters nrog siab - emissivity coatings, phim lub zog ntom ntom rau txheej txheem kub, thiab ua kom muaj kev tswj xyuas thermal. Qhov sib txawv rauv hom (batch, tas mus li), cov ntaub ntawv ua haujlwm (steel, aluminium, ceramics), thiab cua sov cycles yuav tsum tau customized cartridge rhaub layouts thiab tswj systems. Kev tsim qauv kev daws teeb meem ua kom ntev - lub sijhawm ua kom sov kev ntseeg tau, cov khoom zoo ib yam, thiab txo cov nqi ua haujlwm rau siab - kub tsim.
