Piv nrog rau ntau cov ntaub ntawv hnav-tiv taus, Crusher Wear Resistant Liner Board muaj nws cov yam ntxwv zoo tshaj plaws tsis hloov pauv:
1. Cov ntsiab lus ntawm cov khoom siv siab hnav resistant alloy txheej yog 4 ~ 5 feem pua, cov ntsiab lus chromium txog li 25 ~ 30 feem pua, qhov ntim feem ntawm Cr 7 C 3 carbide nyob rau hauv cov ntaub so ntswg metallographic yog ntau tshaj 50 feem pua, macroscopic hardness yog HRC 56 ~ 62, lub hardness ntawm chromium carbide yog HV1400 ~ 1800, siab tshaj qhov hardness ntawm HV 800 ~ 1200. Vim hais tias cov carbide yog faib vertically faib nyob rau hauv cov kev taw qhia ntawm hnav, hnav tsis kam yog ntau tshaj ob npaug txawm tias thaum piv nrog cov casting alloy ntawm tib yam muaj pes tsawg leeg thiab hardness. Sib piv cov hnav tsis kam nrog ntau cov ntaub ntawv raug yog raws li hauv qab no:
(1) thiab cov hlau tsis muaj carbon; 20-25:
(2) Muab piv nrog cov hlau manganese siab; 5 ~ 10:
(3) Thiab cov cuab yeej steel; 5 ~ 10:
(4) nrog cam khwb cia siab chrome cam khwb cia hlau; 1.5 ~ 2.5 hli:
2. Cov kev cuam tshuam zoo: cov txheej hauv qab ntawm cov khoom hnav-tiv taus steel phaj yog cov pa roj carbon tsawg lossis cov hlau tsis tshua muaj hlau. Stainless hlau thiab lwm yam ntaub ntawv toughness, qhia txog qhov zoo ntawm cov hlau bimetal, hnav tsis kam rau hnav ntawm nruab nrab, substrate nyob rau hauv lub load ntawm nruab nrab, yog li nws muaj kev cuam tshuam zoo. Muaj peev xwm tiv taus qhov cuam tshuam thiab hnav ntawm siab poob hopper hauv cov khoom xa khoom.
3. Kev ua haujlwm kub zoo: cov txheej hnav tsis kam yog pom zoo kom siv nyob rau hauv 600 degree kev ua haujlwm. Yog hais tias vanadium, molybdenum thiab lwm yam alloys ntxiv rau cov hlau txheej, nws tuaj yeem tiv taus qhov kub siab ntawm 800 degree. Qhov ntsuas kub tau pom zoo yog raws li hauv qab no: cov pa roj carbon zoo tib yam yog pom zoo kom tsis txhob siab tshaj 380 degree; tsis tshua muaj alloy kub resistant steel phaj (15 CrMo, 12Cr1MoV, thiab lwm yam) substrate yog pom zoo kom siv tsis siab tshaj 540 degree; thiab kub resistant stainless hlau substrate yog pom zoo kom siv tsis siab tshaj 800 degree.
