1. Kev hnav zoo heev: cov tshuaj muaj pes tsawg leeg ntawm cov hlau hnav-resistant txheej muaj cov ntsiab lus carbon ntawm 4-5 feem pua, cov ntsiab lus chromium ntawm 25-30 feem pua, ib feem ntawm Cr7C3 carbides nyob rau hauv nws metallographic qauv ntawm ntau tshaj 50 feem pua, thiab ib tug macroscopic hardness. Nws yog HRC56 ~ 62, thiab hardness ntawm chromium carbide yog HV1400 ~ 1800. Txij li thaum cov carbides raug faib perpendicular rau kev coj coj, txawm tias piv nrog cov cam khwb cia hlau nrog tib lub ntsiab lus thiab hardness, hnav tsis kam yog ntau dua ob npaug. Kev sib piv ntawm kev hnav tsis kam nrog ntau cov ntaub ntawv raug raws li hauv qab no: (1) nrog qis carbon steel; 20-25: 1 (2) nrog li-cam khwb cia high-chromium cam khwb cia hlau; 1. 5-2.5:1.
2. Kev cuam tshuam zoo: lub substrate ntawm hnav-resistant composite steel phaj yog tsawg carbon steel los yog tsawg alloy. Cov ntaub ntawv tawv xws li cov hlau tsis muaj steel muaj kev cuam tshuam zoo tshaj plaws ntawm bimetal, txheej hnav-tiv taus tiv taus hnav ntawm qhov nruab nrab abrasive, thiab lub substrate bears lub load nruab nrab, yog li nws muaj kev cuam tshuam zoo. Nws tuaj yeem tiv taus qhov cuam tshuam thiab hnav ntawm cov hoppers siab hauv cov khoom siv thauj khoom.
3. Kev ua haujlwm kub zoo: Cov txheej txheej alloy hnav-tiv taus yog pom zoo kom siv nyob rau hauv kev ua haujlwm ntawm Tsawg dua lossis sib npaug li 600 degree. Yog hais tias vanadium, molybdenum thiab lwm yam alloys ntxiv rau cov alloy hnav-resistant txheej, nws muaj peev xwm tiv taus high-kub hnav ntawm tsawg dua los yog sib npaug rau 800 degree. Qhov pom zoo ua haujlwm kub yog raws li hauv qab no: cov pa roj carbon steel zoo tib yam tau pom zoo kom tsis txhob siv qhov kub siab tshaj 380 degree; low-alloy heat-resistant steel daim hlau (15CrMo, 12Cr1MOV, thiab lwm yam) raug pom zoo kom siv ntawm qhov kub tsis siab tshaj 540 degree; Thaum tshav kub kub-resistant stainless hlau substrates raug pom zoo kom siv ntawm qhov kub tsis siab tshaj 800 degree ua haujlwm.
4. Zoo corrosion kuj: Cov hlau txheej ntawm hnav-resistant composite steel phaj muaj cov feem pua ntawm cov hlau chromium, yog li nws muaj qee yam kev tiv thaiv xeb thiab corrosion. Nws tuaj yeem tiv thaiv cov thee sticking thaum nws siv rau hauv cov kav dej thiab cov funnels thiab lwm lub sijhawm.
5. Ua tiav ntau yam thiab specifications: hnav-resistant steel daim hlau muaj tiav specifications thiab ntau ntau yam, thiab tau ua serialized khoom. Lub thickness ntawm hnav-resistant alloy txheej yog 3-20 hli. Qhov tuab tshaj plaws ntawm cov hlau phaj sib xyaw yog 6 hli, thiab cov tuab tsis txwv. Tus qauv hnav-resistant steel phaj tuaj yeem muab 1200 lossis 3800 × 12000mm, thiab tuaj yeem hloov kho raws li daim duab loj raws li cov neeg siv khoom xav tau. Wear-resistant steel daim hlau tam sim no tau muab faib ua peb hom: hom zoo tib yam, hom kev cuam tshuam-resistant thiab hom kub kub. Thaum txiav txim siab-kub hnav-tiv taus thiab cuam tshuam-tiv taus cov hlau phaj, thov piav qhia.
6. Kev ua haujlwm yooj yim: cov phaj hnav-resistant steel tuaj yeem txiav, khoov lossis curled, welded thiab xuas nrig ntaus, thiab nws tuaj yeem ua tiav rau ntau qhov chaw uas cov hlau zoo tib yam tuaj yeem ua tau. Qhov txiav hnav-resistant steel phaj tuaj yeem raug txiav thiab welded rau hauv ntau yam khoom siv hluav taws xob lossis qhov chaw.
7. Muaj nuj nqi thiab nta: weldable, zoo hnav tsis kam.
