Cov Khoom Siv Taw Qhia rau Kev Ruaj Ntseg 950 Degree Ua Haujlwm Cartridge rhaub
Thermal degradation thiab luv-circuit faults tseem yog ob qho tib si tsis ua hauj lwm hom ntawm cartridge rhaub nyob rau hauv siab -kub ua hauj lwm rhiav, feem ntau yog los ntawm tsis tsim nyog raw khoom xaiv incompatible nrog 950℃tsis tu ncua ua hauj lwm tej yam kev mob. Ntau cov khoom siv hluav taws xob hluav taws xob siv hluav taws xob txiav cov khoom siv los ntawm kev siv qis- qib stainless hlau sheaths thiab zoo tib yam magnesium oxide muab tub lim, uas poob rwb thaiv tsev kev ua tau zoo thiab cov qauv kev ntseeg siab ib zaug ambient kub nce siab tshaj 800 degree. Xaiv cov khoom siv sab hauv thiab sab nrauv kom zoo yog lub hauv paus rau kev ua haujlwm zoo ib yam ntawm kev kub siab 950℃cartridge rhaub nrog 5-7 W / cm² lub zog ntom ntom.
Cartridge rhaub sheath cov ntaub ntawv bears ncaj qha thermal yaig thiab oxidation ntawm ncov 950℃ua hauj lwm kub, ua alloy qib cov thawj kev tshuaj ntsuam tus qauv . 304 stainless hlau sheaths tsuas yog tuav ruaj khov nyob rau hauv 700 degree; Lub sij hawm ntev raug rau 950℃ib puag ncig ua rau muaj qhov hnyav oxidation txheej txheej txheej, thaiv cov cua sov hloov mus rau hauv cheeb tsam overheating zones ntawm cartridge rhaub nto. 316 stainless hlau me ntsis txhim kho oxidation kuj tab sis tseem tsis tuaj yeem tiv taus cyclic 950℃cua sov rau ntev - lub sij hawm ntau lawm. Incoloy 800 alloy serves as the optimal sheath material for ultra high temperature 950℃cartridge heater, containing balanced nickel, chromium and iron components that form a dense anti-oxidation protective film under constant high heat, resisting thermal fatigue and chemical corrosion from metal vapor generated during forging and extrusion processes. Tag nrho cov ntawv pov thawj 5-7 W / cm² cartridge rhaub cov qauv rau 950℃kev pabcuam txais yuav seamless Incoloy 800 tubing kom tsis txhob tawg los ntawm thermal expansion thiab contraction cycles.
Rwb thaiv tsev muab tub lim cov ntaub ntawv nyob rau hauv cartridge rhaub dictates qhov kub thiab txias thiab hluav taws xob kev nyab xeeb. Ordinary muaj magnesium oxide hmoov uas tsis muaj purity muaj impurity cov ntsiab lus uas ua rau cov khoom siv hluav taws xob siab tshaj 850 degree, tsim kom muaj hluav taws xob sab hauv tam sim no thiab luv luv Circuit Court txaus ntshai rau lub tshuab cua sov. High-purity fused crystalline magnesium oxide nrog ultra- cov ntsiab lus tsis zoo impurity khaws cov rwb thaiv tsev siab txawm tias nyob rau ntawm 950℃core kub, zoo xaim hluav taws xob los ntawm cov hlau tsis kam mus rau sab nraud yam tsis muaj hluav taws xob tsis zoo. Production processes for qualified ultra high temperature cartridge heater include high-density compaction of magnesium oxide filler through precision swaging, which stabilizes the actual power density within the standard 5 to 7 W/cm² range. Tsis txaus compaction tso cua voids nyob rau hauv lub cartridge rhaub, txo cov cua sov conduction efficiency thiab artificially tsa lub zog nyob rau hauv lub cheeb tsam tshaj li kev nyab xeeb txwv.
Resistance hlau qib ncaj qha cuam tshuam cov hluav taws xob tso zis ruaj khov ntawm 950℃cartridge rhaub nrog calibrated 5-7 W / cm² zog ceev. Tsawg-qib hlau-chromium-aluminium xaim ua rau muaj kev tiv thaiv sai tshaj 900 degree, ua rau cov hluav taws kub hloov pauv thiab qhov kub tsis sib xws ntawm cov khoom siv hluav taws xob. High-kub npib tsib xee-chromium alloy tsis kam hlau tuav ruaj khov nyob rau hauv kev ua haujlwm tas li 950 degree, txhawb nqa lub zog zoo ib yam yam tsis muaj kev cuam tshuam dhau ntau txhiab lub sijhawm ua haujlwm. Hlau txoj kab uas hla suav nrog nruj me ntsis raws li lub hom phiaj 5-7 W / cm² lub zog ntom ntom kom tsis txhob muaj cov xaim nyias nyias uas melts nyob rau hauv lub ncov thermal load los yog cov hlau tuab heev uas tsim cov khoom siv loj loj uas tsis tuaj yeem ua kom haum cov qhov sib txuas.
Cov kev lag luam sib txawv xav tau cov khoom siv ntxiv hloov kho rau qhov kub siab tshaj 950℃cartridge rhaub. Cov kab ntau lawm tsim cov sulfur, zinc los yog txhuas vapor yuav tsum tau ntxiv nto tiv thaiv -corrosion txheej ntawm Incoloy 800 sheath kom qeeb tshuaj oxidation. Lub tshuab nqus tsev siab-cov khoom siv ua haujlwm kub xav tau cov khoom siv hermetically kaw lub tshuab cua sov lub davhlau ya nyob twg nrog siab - kub kub ceramic insulation caps kom tsis txhob muaj cua nkag mus rau hauv cov khoom ua kom degradation. Dej-tso txias auxiliary cua sov tshuab ua ke 950℃cartridge rhaub nrog cua sov- ua cov tes tsho tooj liab kom nrawm cov cua sov thiab tuav lub zog ceev hauv qhov muaj kev nyab xeeb 5-7 W / cm² qhov rai nyob rau hauv kev ua haujlwm tsis tu ncua.
Cov khoom sib txuam ua yuam kev tsim qhov zais ntev - cov nqi poob txawm tias qis dua cov nqi yuav khoom. Hloov cov khoom siv hluav taws xob ua tsis tiav thiab tso tseg cov kab ntau lawm ua rau muaj kev siv nyiaj ntau dua li kev nqis peev hauv cov ntawv pov thawj siab siab -cov khoom siv kub. Cov khoom siv sib xyaw ua ke sib haum rau kev ua haujlwm nruab nrab, lub sijhawm kub siab tshaj plaws thiab kev teeb tsa ib puag ncig xyuas kom lub tshuab rhaub dej kub tswj hwm 950℃kev ua tau zoo thiab tus qauv 5-7 W / cm² lub zog ntom ntom thoob plaws lub sijhawm ua haujlwm tiav.
