Dab tsi yog qhov muaj pes tsawg leeg ntawm Monel 400?
Lub ntsiab
Muaj ntau ntau yam sib txawv ntawm monel alloy, pib nrog monel 4 {}}} {} {% rau 2.5% hlau, thiab 1.5% mus rau 2% manganese. Monel 4 0}}}}}}}} Tsis muaj ntau tshaj 0.5%}% thiab 3.15% aluminium thiab 0.85% titanium. Cov kev sib txawv thiab lwm qhov kev hloov pauv rau lawv txoj kev tiv thaiv kom tawm tsam los ntawm cov kua qaub thiab alkalis, muaj zog dua, thiab ua kom zoo dua qub.
Monel 400 muaj tib lub npib tsib xee thiab tooj pom nyob rau hauv ib txwm muaj tshwm sim rau Nickel ores hauv Ontario, Canada. Nws muaj lub zog siab thiab tsuas yog ua kom tawv los ntawm kev ua haujlwm txias. Vim nws corrosion tsis kam, monel 400 feem ntau siv rau cov khoom siv hauv cov tub rog thiab tshuaj ib puag ncig.
Thaum nws yog cov hlau tseem ceeb heev, nws yog nqi-txwv rau feem ntau cov ntawv thov. Monel 400 nqi 5 txog 10 zaug ntau dua li cov npib tsib xee lossis tooj liab. Raws li qhov tshwm sim, nws tsis tshua muaj siv-tsuas yog thaum tsis muaj lwm yam hlau tuaj yeem ua tib txoj haujlwm. Piv txwv li, monel 400 yog ib qho ntawm ob peb alloys uas khaws nws lub zog hauv subzero kub, yog li nws yog siv nyob rau hauv xws li ib puag ncig.
Kev yuav
Cov txheej txheem ua rau ferrous alloys tuaj yeem siv rau Monel 400, txawm hais tias qhov no yog qhov nyuaj vim tias nws ua kom tawv thaum ua. Yog tias lub hom phiaj yog kom tawv monel 400, tom qab ntawd ua haujlwm txias nrog cov khoom siv mos muag yog qhov kev xaiv ntawm mos nkaus xwb. Nrog kev ua haujlwm txias, kev ntxhov siab yog siv ntau dua li cov cua sov kom hloov cov duab ntawm cov hlau.
Roj Arc Vuam, hlau arc vuam, roj hluav taws xob hlau vuam, thiab cov twj kub tau ua tiav rau ntawm monel 400. Thaum kub} Nws tuaj yeem ua tau tshaj tawm ntawm 926 degrees Celsius (1,700 degrees Fahrenheit).
Cov Ntawv Thov
Vim tias nws txoj kev tiv thaiv cov acids, alkalis, thiab dej hiav txwv, monel 400 feem ntau siv nyob rau hauv cov ntawv thov uas yog ib qho teeb meem. Qhov no suav nrog cov chaw ua haujlwm marine uas cov khoom siv, li qub, twj, thiab cov raj xa xov yuav tsum tau ua.
Lwm yam kev thov qee zaum muaj cov nroj tsuag tshuaj chemical, suav nrog cov neeg ib puag ncig uas yog cov sulfuric thiab hydrofluoric acids yog siv.
