Yam ntxwv thiab daim ntawv thov teb ntawm tracked ceramic electric heaters

Ceramic hluav taws xob cua sov raj muaj ntau yam kev siv. Ceramic hluav taws xob cua sov raj, tseem paub thoob ntiaj teb raws li cov cua sov hloov tau yooj yim, yog ua los ntawm cov khoom siv zoo nickel chromium alloy hlau cables, coated nrog high-purity alumina ceramic rwb thaiv tsev Cheebtsam, thiab ua rau hauv kab los yog hlua cua sov thiab lwm yam khoom siv. Nws tuaj yeem ua raws li cov duab thiab qhov loj ntawm lub workpiece, thiab tuaj yeem sib txuas, khoov, thiab qhwv nruj nreem tiv thaiv lub workpiece rau cua sov. Qhov siab tshaj plaws saum npoo tuaj yeem ncav cuag 1050 degree. Nws muaj cov yam ntxwv ntawm kev siv ntau yam, cua kub ceev, kev siv hluav taws xob siab, kev txuag hluav taws xob tseem ceeb, kev siv zog tsawg, thiab kev ua haujlwm yooj yim. Haum rau vuam preheating thiab kev ntxhov siab ntawm ntau yam hlau, xws li cov yees loj, cov hlab ntsha siab, txuas hniav, thiab cov kav dej siab. Nws kuj tseem tuaj yeem siv rau kev pabcuam cua sov ntawm cov kav dej tshuaj, ntim khoom, thiab lwm yam. Nws yog cov khoom siv cua sov hauv zos zoo tagnrho.

Qhov ntev thiab dav qhov ntev ntawm lub tshuab hluav taws xob cov khoom siv hluav taws xob tuaj yeem hloov pauv tau yooj yim, thiab cov kev qhia tshwj xeeb yuav tsum raug xaiv raws li cov duab geometric, phab ntsa thickness, thiab cov txheej txheem kho cua sov ntawm cov khoom ua haujlwm. Cov lus hauv qab no tsuas yog sau qee qhov tshwj xeeb. Tsis tas li ntawd, cov cuab yeej siv hluav taws xob tuaj yeem tuaj yeem nruab nrog cov ntaub ntawv rwb thaiv tsev thiab cov plhaub ua rau nws tus kheej insulating cov cua sov, uas tuaj yeem ua tau raws li cov duab tiaj tus, lub kaum sab xis, thiab lwm yam, ua rau lawv yooj yim siv.

Qhov zoo thiab qhov tsis zoo ntawm hlau chromium aluminium thiab nickel chromium feem

Qhov zoo thiab qhov tsis zoo ntawm hlau chromium aluminium thiab nickel chromium feem. Txhawm rau tham txog cov yam ntxwv ntawm cov hlau chromium aluminium thiab npib tsib xee chromium, nws yog ib qho tsim nyog yuav tsum xub nkag siab txog cov khoom ntawm ob. Lub qub belongs rau cov khoom siv hlau nrog cov qauv ferrite, thaum lub tom kawg belongs rau cov khoom siv hlau nrog cov qauv austenite. Tsis tas li ntawd, muaj qee lub hom phiaj tshwj xeeb hluav taws xob cua sov hlau hlau xws li tungsten xov hlau, molybdenum xov hlau, thiab lwm yam.

Qhov zoo ntawm cov hlau chromium txhuas hluav taws xob rauv hlau hluav taws xob cua sov cov khoom siv yog:

1. Kev siv kub siab, xws li qhov siab tshaj plaws kev siv kub ntawm HRE hlau chromium aluminium alloy hlau nyob rau hauv qhov chaw tuaj yeem ncav cuag 1400 degree;

2. Nws muaj kev ua haujlwm zoo antioxidant thiab tsim AI2O3 zaj duab xis tom qab oxidation, uas muaj cov tshuaj tiv thaiv zoo thiab siab tiv taus.

3. Lub neej ua haujlwm ntev;

4. Lub tso cai nto load yog loj;

5. High resistivity thiab zoo sulfur kuj;

6. Qhov tshwj xeeb lub ntiajteb txawj nqus yog me dua li ntawm npib tsib xee chromium alloy, thiab tus nqi qis dua li ntawm cov nickel chromium alloy;

7. Qhov tsis zoo yog tias qhov kub nce, nws nthuav tawm plasticity thiab tsis muaj zog ntawm qhov kub thiab txias.

Qhov zoo ntawm nickel chromium hluav taws xob rauv hlau yog:

1. Lub zog muaj zog ntawm qhov kub thiab txias;

2. Tom qab siv lub sij hawm ntev thiab txias ntxiv, cov khoom yuav tsis nkig;

3. Tus nqi hluav taws xob ntawm tag nrho oxidized nickel alloy yog siab dua li ntawm cov hlau chromium aluminium alloy;

4. Tsis muaj hlau nplaum;

5. Zoo corrosion kuj tshwj tsis yog rau cov huab cua sulfur
