Hnav - Resistance Enhancement Aspect

 

Txoj Cai: Cov tebchaw tsim los ntawm manganese hauv cov hlau tuaj yeem txhim kho qhov hnav - tsis kam ntawm cov hlau. Thaum manganese sib xyaw nrog cov pa roj carbon monoxide hauv cov hlau los tsim cov khoom sib txuas xws li manganese carbide (MnC), cov khoom sib txuas no muaj qhov tawv tawv thiab raug faib rau hauv cov hlau matrix, uas tuaj yeem tiv taus hnav.

 

Tswj cov txheej txheem thiab cov teebmeem: Thaum tsim cov hlau rau cov tshuab mining, cov ntsiab lus manganese tuaj yeem nce mus rau 1.2% - 1.8%. Los ntawm tsim nyog alloying tsim thiab manganese cov ntsiab lus tswj, ib tug tsim nyog tus nqi ntawm hnav - resistant theem yog tsim nyob rau hauv cov hlau. Nyob rau hauv ib puag ncig hnyav xws li mining, hnav - tsis kam ntawm no hnav - resistant steel tuaj yeem yog 1 - 2 zaug siab dua li cov hlau zoo tib yam, ua kom lub neej ntev kev pab cuam ntawm mining machinery Cheebtsam.

Corrosion - Resistance Optimization Aspect

 

Txoj Cai: Manganese tuaj yeem hloov cov qauv ntawm qhov chaw oxide zaj duab xis ntawm cov hlau thiab txhim kho corrosion - tsis kam ntawm cov hlau. Nyob rau hauv tej yam kev mob, lub manganese caij yuav txhawb cov tsim ntawm ib tug ntom thiab nruam oxide zaj duab xis, tiv thaiv oxygen thiab corrosive xov xwm los ntawm ntxiv eroding lub steel matrix.

 

Tswj cov txheej txheem thiab cov teebmeem: Rau qee qhov stainless hlau siv nyob rau hauv marine los yog tshuaj ib puag ncig, ib tug tsim nyog tus nqi ntawm manganese yog ntxiv (xws li, cov ntsiab lus nyob nruab nrab ntawm 1.0% thiab 1.4%). Thaum lub sij hawm tsim cov hlau tsis muaj steel, cov ntsiab lus ntawm manganese thiab cov feem ntawm lwm cov hlau alloy (xws li chromium thiab npib tsib xee) raug tswj kom nruj kom cov oxide zaj duab xis nto nrog kev tiv thaiv zoo yog tsim los ntawm cov hlau. Lub corrosion - tsis kam ntawm no stainless hlau nyob rau hauv ib puag ncig uas muaj chloride ions thiab lwm yam corrosive media tuaj yeem txhim kho tau zoo, thiab nws lub neej kev pab cuam txuas ntxiv mus.
