Dab tsi yog qhov zoo ntawm cov hlau chromium txhuas hluav taws xob cua sov hlau?

Dab tsi yog qhov zoo ntawm cov hlau chromium txhuas hluav taws xob cua sov hlau?

1. Siv qhov kub thiab txias hauv qhov chaw

Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm HRE alloy nyob rau hauv hlau chromium txhuas hluav taws xob cua sov alloy yuav ncav cuag 1425 degree, thaum lub siab tshaj plaws kev khiav hauj lwm kub ntawm Cr20Ni80 alloy nyob rau hauv nickel chromium hluav taws xob cua sov alloy yog 1200 degree.

2. Kev pab lub neej

Nyob rau tib lub siab ua haujlwm kub hauv huab cua, lub neej ntev ntawm cov hlau chromium txhuas cov khoom tuaj yeem yog 2-4 npaug ntawm cov khoom nickel chromium.

3. High deg load

Vim yog qhov kub thiab txias thiab kev pab lub neej ntev ntawm cov hlau chromium aluminium alloy, qhov saum npoo ntawm cov khoom tseem tuaj yeem siab dua, uas tsis tsuas yog tso cai rau cua sov sai dua tab sis kuj txuag cov ntaub ntawv alloy.

4. Kev ua haujlwm zoo antioxidant

Lub al2o3 zaj duab xis tsim nyob rau saum npoo ntawm cov hlau chromium alloy alloy muaj qhov qauv tuab, thiab tsis yooj yim los ua cov qias neeg vim tawg. Tsis tas li ntawd, lub siab hluav taws xob tiv thaiv thiab melting point ntawm Al2O3 txiav txim siab tias Al2O3 oxide zaj duab xis muaj oxidation zoo heev thiab zoo carburization tsis kam tshaj Cr2O3 tsim nyob rau saum npoo ntawm nickel chromium alloy.

5. Me me lub ntiajteb txawj nqus

Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm hlau chromium aluminium alloy yog me dua li ntawm nickel chromium alloy, uas txhais tau hais tias siv hlau chromium aluminium los ua cov khoom sib npaug yog cov khoom siv ntau dua li siv cov nickel chromium.

6. Muaj hluav taws xob tiv taus

Cov hluav taws xob tiv thaiv ntawm hlau chromium aluminium alloy yog siab dua li ntawm nickel chromium alloy. Thaum tsim cov khoom siv, cov khoom siv tshwj xeeb loj dua tuaj yeem xaiv tau, uas yog qhov zoo rau kev ua haujlwm ntev ntawm cov khoom siv. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov hlau hlau zoo. Thaum xaiv cov khoom siv nrog tib qhov tshwj xeeb, qhov siab dua qhov kev tiv thaiv, cov khoom siv ntau dua tau txais kev cawmdim, thiab qhov chaw me me ntawm cov khoom hauv lub cub tawg. Tsis tas li ntawd, cov hluav taws xob tiv thaiv ntawm hlau chromium aluminium alloy tsis tshua muaj kev cuam tshuam los ntawm kev ua haujlwm txias thiab kev kho cua sov dua li nickel chromium alloy.

7. Zoo sulfur tsis kam

Hlau, chromium, thiab txhuas muaj kev tiv thaiv corrosion zoo thaum raug cov huab cua uas muaj leej faj thiab cov chaw uas muaj cov tshuaj sulfur, thaum npib tsib xee thiab chromium raug corroded hnyav heev.

8. Tus nqi pheej yig

Hlau chromium txhuas yog pheej yig dua li nickel chromium vim nws tsis muaj tsawg nickel. Lub ntsiab drawback ntawm hlau chromium aluminium alloy yog nws tsis muaj high-temperature zog, thiab nws plasticity nce nrog nce kub. Cov ntaub ntawv siab tshaj 1000 degree feem ntau elongate qeeb vim lawv qhov hnyav, ua rau cov khoom deformation. Tsis tas li ntawd, tom qab siv sij hawm ntev ntawm qhov kub thiab txias nrog rau lub qhov cub, nws ua nkig thaum cov nplej loj tuaj thiab tsis tuaj yeem khoov rau hauv lub xeev txias. Cov kev tsis txaus no yuav tsum zam thiab kov yeej hauv kev tsim thiab siv.
