Thaum xaiv cov ntaub ntawv rau lub tso cua sov, kev saib xyuas yuav tsum tsis txhob ua kom cov hluav taws xob cua sov ncaj qha rau cov pa taws. Vim tias cov hlau-chromium-aluminium alloy muaj cov ntsiab lus zoo ntawm chromium, hauv kev siv tiag tiag, yog tias cov pa roj carbon nkag ncaj qha rau cov hlau-chromium-aluminium alloy, nws yuav sib xyaw nrog cov chromium hauv cov alloy los tsim cov pa roj carbon thiab chromium, uas yuav muab faib rau hauv Ntawm thaj tsam ntawm cov nplej, vim yog qhov ntim nthuav tawm tom qab qhov sib txuas ua ke, cov hlau" bulges" tshwm sim, uas zoo heev luv lub alloy lub neej.
Tus kws tsim choj pom tias cov khoom siv cua sov ntawm cov hluav taws xob carburizing cua sov yuav tsum tau muab cais kom nruj ntawm cov pa roj carbon cua kom tiv thaiv cov cua kub hlau los ntawm carburizing. Yog tias txoj hauv kev tsim qauv sib khi tau txais yuav, nws yog qhov zoo tshaj rau pre-oxidize cov hlau-chromium-aluminium hluav taws xob cua sov hluav taws xob hlau ntawm 950 ° C rau li 6 teev ua ntej sib khi, tom qab cov hlau-chromium-aluminium hluav taws xob cua sov hlau tau ntsia rau hauv kev sib khi ntaus ntawv, kom txog thaum lub npoo ntawm cov hlau-chromium-aluminium hluav taws xob ua kom sov hlau tig nyiaj grey los yog Tom qab dawb, foob nws thiab siv nws dua. Txawm li cas los xij, nco ntsoov tias lub xov hluav taws xob xaim yuav ua nkig tom qab ua ntej-oxidation. Thaum pre-oxidized, nws tsis tuaj yeem deformed los yog raug rau ntau dhau kev quab yuam sab nraud.
Ua ntej tshaj plaws, koj yuav tsum to taub cov yam ntxwv ntawm cov hlau-chromium-aluminium hluav taws xob cua sov xaim hluav taws xob cua sov cov ntaub ntawv hluav taws xob yog:
①Qhov kev siv kub yog qhov siab, piv txwv li, qhov siab tshaj plaws siv qhov kub thiab txias ntawm HRE hlau-chromium-aluminium alloy hlau nyob rau hauv cov huab cua tuaj yeem ncav cuag 1400 ℃;
② Ntev pab lub neej;
Txoj pub ua haujlwm saum npoo loj;
④Good oxidation tsis kam, AI2O3 zaj duab xis tsim tom qab oxidation muaj tshuaj lom neeg zoo thiab siab resistivity;
Cov qauv nqus tshwj xeeb tsawg dua li ntawm nickel-chromium alloy;
⑥High resistivity;
OodGur leej faj tsis kam;
Tus nqi ntawd tseem qis dua li ntawm nickel-chromium alloy;
Disadvant Qhov tsis zoo yog tias thaum qhov kub nce ntxiv, qhov ua tau zoo yog cov yas, thiab lub zog thaum kub siab yog tsawg.
Lub tshuab hluav taws xob cua sov hlau tsim los ntawm peb lub tuam txhab tau muag muag ua ntej ua tiav, thiab muaj cov yas zoo thiab tawv. Nws tuaj yeem ua ncaj qha rau muab kauv, corrugated, Z-hloov, thiab hom winding; cov hluav taws xob cua sov hlau xaim txheej txheem los ntawm peb lub Hoobkas yog coreless Winding molding tuaj yeem tiv thaiv qhov khawb ntawm saum npoo ntawm cua sov xaim kom ua tau zoo tshaj plaws. Nws muaj cov yam ntxwv ntawm kev lag luam txheem molding, lub suab sib tw, thiab tiv thaiv nto tsis muaj kev puas tsuaj.
