Lub phaj steel yog ib lub tiaj tus hlau uas yog cam khwb cia nrog molten steel thiab nias tom qab txias.Nws yog tiaj, duab plaub thiab tuaj yeem ncaj qha dov los yog txiav los ntawm dav hlau strips.Cov hlau phaj yog muab faib raws li thickness, nyias steel phaj yog tsawg tshaj li 4 hli (thinnest yog 0.2 hli), nruab nrab-tuab steel phaj yog 4-60 hli, thiab lub thickness ntxiv steel phaj yog 60-115. mm.Lub phaj steel yog muab faib ua kub-kuav los tiag thiab txias-dov los ntawm dov.Qhov dav ntawm lub phaj nyias yog 500 ~ 1500 hli;qhov dav ntawm daim ntawv tuab yog 600 ~ 3000 hli.Cov nplooj ntawv raug cais raws li cov hlau, suav nrog cov hlau zoo tib yam, cov hlau zoo, cov hlau alloy, lub caij nplooj ntoo hlav, cov hlau tsis muaj steel, cov cuab yeej hlau, cov hlau tsis muaj cua sov, cov kabmob steel, silicon steel thiab cov ntawv hlau ntshiab, thiab lwm yam.;Raws li kev siv, muaj roj nruas phaj, Enamel phaj, mos txwv phaj, thiab lwm yam .;Raws li cov txheej txheem saum npoo, muaj cov ntawv galvanized, tin-plated ntawv, cov ntawv txhuas-plated, yas composite steel phaj, thiab lwm yam. Wear Resistant Steel Phaj: Hnav Resistant Steel Phaj hais txog cov khoom siv phaj tshwj xeeb tsim los siv rau hauv cheeb tsam loj. hnav tej yam kev mob.Feem ntau siv hnav-resistant steel phaj yog cov khoom siv phaj ua los ntawm ib qho tuab ntawm cov alloy hnav-tiv taus txheej nrog siab hardness thiab zoo heev hnav tsis kam rau saum npoo ntawm cov hlau tsis tshua muaj carbon steel lossis cov hlau tsis tshua muaj hlau nrog zoo toughness thiab plasticity. los ntawm txoj kev surfacing.Tsis tas li ntawd, muaj cam khwb cia hnav-resistant steel daim hlau thiab alloy quenched hnav-resistant steel daim hlau.
Cov yam ntxwv ntawm kev hnav-tiv taus steel phaj: hnav-tiv taus steel phaj yog tsim los ntawm cov pa roj carbon tsawg thiab cov txheej txheej alloy hnav-resistant.Lub alloy hnav-resistant txheej feem ntau yog 1/3 ~ 1/2 ntawm tag nrho cov tuab.Thaum ua haujlwm, lub matrix muab cov khoom zoo xws li lub zog, toughness thiab plasticity tiv thaiv sab nraud quab yuam, thiab alloy hnav-resistant txheej muab cov khoom hnav-tiv taus uas ua tau raws li cov kev cai ntawm kev ua haujlwm.Muaj kev sib txuas ntawm cov hlau nplaum ntawm cov hnav-resistant steel phaj alloy hnav-resistant txheej thiab cov substrate.Los ntawm cov cuab yeej tshwj xeeb thiab cov txheej txheem vuam tsis siv neeg, lub siab tawv tawv tiv thaiv tus kheej vuam hlau yog uniformly welded ntawm lub substrate, thiab tus naj npawb ntawm cov khaubncaws sab nraud povtseg yog ib mus rau ob lossis ntau txheej.Thaum lub sij hawm cov txheej txheem sib xyaw, vim qhov sib txawv shrinkage piv ntawm cov hlau, cov kab nrib pleb sib txawv tshwm sim.Nws yog ib qho txawv feature ntawm hnav-resistant steel phaj.Lub alloy hnav-resistant txheej yog tsim los ntawm chromium alloy, thiab lwm yam alloys xws li manganese, molybdenum, niobium, thiab npib tsib xee kuj ntxiv.Cov carbides nyob rau hauv metallographic qauv yog faib nyob rau hauv fibers, thiab cov kev taw qhia fiber ntau yog perpendicular rau saum npoo.Lub microhardness ntawm carbide tuaj yeem ncav cuag HV1700-2000 lossis ntau dua, thiab qhov tawv tawv tuaj yeem ncav cuag HRC58-62.Alloy carbide muaj qhov ruaj khov ntawm qhov kub thiab txias, tswj kev ua haujlwm siab, thiab tseem muaj cov oxidation zoo, thiab tuaj yeem siv tau ib txwm nyob rau hauv 500 ℃.Cov txheej hnav-tiv taus muaj qhov nqaim (2.5-3.5mm), qhov dav dav (8-12mm), nkhaus (S, W), thiab lwm yam;Nws yog tsuas yog tsim los ntawm chromium alloys, thiab manganese, molybdenum, niobium, npib tsib xee, boron kuj ntxiv.thiab lwm yam alloys, cov carbides nyob rau hauv metallographic qauv yog faib nyob rau hauv fibers, thiab cov kev taw qhia fiber ntau yog perpendicular rau saum npoo.Cov ntsiab lus carbide yog 40-60%, microhardness tuaj yeem ncav cuag HV1700 lossis ntau dua, thiab qhov tawv tawv tuaj yeem ncav cuag HRC58-62.Kev hnav-tiv taus steel phaj feem ntau muab faib ua peb hom: hom hom phiaj dav dav, hom kev cuam tshuam-resistant thiab hom kub-resistant;tag nrho cov tuab ntawm cov hlau-resistant steel phaj tuaj yeem ncav cuag 5.5 (2.5 + 3) mm thiab qhov siab tshaj plaws thickness tuaj yeem ncav cuag 30 (15 + 15) mm;hnav-resistant steel phaj Nws tuaj yeem yob cov kav dej uas muaj qhov tsawg kawg nkaus ntawm DN200, thiab tuaj yeem ua tiav rau hauv lub luj tshib hnav-tiv taus, hnav-tiv taus tees, thiab hnav-resistant txo cov kav dej.Technical parameters ntawm hnav-resistant steel phaj: hardness, HRC hnav-resistant txheej thickness ≤ 4mm: HRC54-58;Hnav-resistant txheej thickness> 4mm: HRC56-62 Cov tsos tsis zoo Flatness: 5mm / M
