Dab tsi yog qhov txawv ntawm NM500 thiab AR500?
Thaum yuav khoom hnav- cov hlau tsis muaj zog rau kev khawb, kev tsim kho, lossis kev tuav cov khoom, ntau tus neeg yuav khoom tsis meej pem NM500 thiab AR500. Ob qho tib si tau siv dav, tab sis lawv qhov sib txawv ntawm qhov sib xyaw, hardness, hnav tsis kam, thiab daim ntawv thov scenarios yog qhov tseem ceeb. Xaiv qhov tsis ncaj ncees lawm yuav ua rau lub neej ua haujlwm luv thiab nce nqi. Kab lus no ua kom yooj yim rau lawv qhov sib txawv tseem ceeb los pab koj xaiv cov khoom tsim nyog.
NM500 yog dab tsi?
NM500 yog ib qho khoom siv hauv tsev ua tau siab -lub zog hnav- cov phaj hlau tsis muaj zog. "NM" stands rau "hnav-resistant" hauv pinyin, thiab "500" qhia tias nws Brinell hardness yog kwv yees li 500 HBW (tiag tiag 480-525 HBW). Nws yog feem ntau xa hauv lub xeev quenched thiab tempered. Nws hnav tsis kam yog 3-5 npaug ntawm cov hlau zoo tib yam. Nws yog dav siv nyob rau hauv siab - coj cov khoom xws li excavator thoob, crusher liners, mine chutes, thiab pob tseg tsheb pem teb daim hlau, ua rau lub neej ntev ntawm cov cuab yeej thiab txo cov nqi tu.
AR500 yog dab tsi?
AR500 hnav-resistant steel phaj yog siab-hardness (ib txwm hardness 477-550 HBW) thiab siab-lub zog hnav-resistant steel phaj. Nrog nws cov kev tiv thaiv zoo heev rau zawv zawg hnav thiab cuam tshuam, nws yog dav siv hauv kev siv hnyav xws li mining, excavation, loader thoob, crushers, thiab conveyor troughs. Nws tuaj yeem txuas ntxiv cov cuab yeej siv lub neej thiab txo qis sijhawm rau kev hloov pauv.

UA 500
AR500 hnav-cov hlau tsis muaj zog siv cov khoom siv tsawg- alloy muaj pes tsawg leeg, nrog cov ntsiab lus carbon feem ntau tswj ntawm thaj tsam 0.25% - 0.35%, chromium ntawm kwv yees li 0.50% -1.50%, molybdenum ntawm kwv yees li 0.20% - 0.50%, thiab 5 qhov sib npaug ntawm 0. hardenability. Lub siab -carbon, chromium-molybdenum composite alloy tsim ua rau muaj siab dua ua ntej-hardened deg hardness (477–534 HBW), ua rau nws tshwj xeeb tshaj yog haum rau kev ua kom huv si. Txawm li cas los xij, cov ntsiab lus ntawm manganese kuj tsawg, thiab cov pa roj carbon sib npaug yog siab, yuav tsum tau ua kom sov thiab ua kom txias qeeb thaum lub sij hawm vuam thiab txias txias. Corrosion kuj feem ntau yog nruab nrab, tab sis nyob rau hauv xov xwm uas muaj cov kab ntawm cov kua qaub, cov ntsiab lus chromium muab ib qho kev txhawb zog rau hnav tsis kam.
NM 500
NM500 yog lub siab -hardness coj- steel phaj. Txhawm rau kom ua tiav cov hardness siab dua thiab hnav tsis kam, cov ntsiab lus ntawm cov ntsiab lus alloying tau nce ntxiv. Qhov sib ntxiv ntawm cov lej ntawm boron (0.0005% - 0.006%) ntxiv txhim kho hardenability. Vim muaj cov ntsiab lus ntawm tag nrho cov alloy, cov pa sib npaug (CEV) ntawm NM500 nce mus txog kwv yees li 0.65, txhais tau hais tias nws nyuaj rau vuam thiab tshuab ntau dua NM400.
Hardness thiab hnav tsis kam
Ob leeg muaj Brinell hardness zoo sib xws (NM500: 480-520 HBW; AR500: 470-530 HBW), tab sis NM500 muaj qhov sib xws zoo dua. NM500's Cr thiab Mo cov ntsiab lus ua rau nws hnav tsis kam 1.2-1.5 npaug ntawm AR500 hauv cov xwm txheej hnyav, thaum AR500 txaus rau qhov nruab nrab hnav ib puag ncig.

Hauv qhov xwm txheej twg koj yuav tsum xaiv NM500 tsis yog AR500?
Thaum muaj cov kev xav tau siab dua rau kev cuam tshuam qhov hnyav, qis - qhov kev cia siab rau qhov kub thiab txias, thiab kev sib txuas / txias ua phooj ywg, NM500 yuav tsum nyiam tshaj AR500.
NM500 yuav tsum nyiam nyob rau hauv plaub qhov xwm txheej hauv qab no:
High- tej yam kev mob tshwm sim: Thaum cov cuab yeej yuav tsum tau tiv thaiv kev cuam tshuam rov qab thiab muaj zog vibrations los ntawm cov khoom loj ntawm cov ore thiab pob zeb, qhov zoo tshaj plaws ductility thiab cuam tshuam toughness ntawm NM500 txo qhov kev pheej hmoo ntawm kev puas tsuaj. Tej yam khoom xws li crusher liners thiab thee mining tshuab chutes yog haum rau qhov no scenario.
Tsawg-kub ib puag ncig kev ua haujlwm: Thaum cov cuab yeej ua haujlwm nyob rau sab qaum teb lub caij ntuj no, siab - thaj chaw siab, lossis txawm tias thaj chaw khov, NM500 (tshwj xeeb tshaj yog qib NM500D/E) tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev cuam tshuam ntawm qhov kub ntawm qhov kub ntawm -20℃txog -40 degree. Hauv qhov sib piv, tus qauv AR500 tsis yog tsim tshwj xeeb rau cov ntawv thov kub qis thiab ua rau muaj kev pheej hmoo ntawm qhov kub thiab txias tawg.
Kev tsim khoom thiab kev kho kom yooj yim: Rau cov ntawv thov uas xav tau kev vuam dav dav, khoov, lossis tom qab ntawm - qhov chaw vuam kho, qhov sib npaug ntawm cov pa roj carbon tsawg ntawm NM500 muab qhov zoo tshaj plaws weldability thiab txias - ua haujlwm ua haujlwm, txo qis preheating thiab post-weld processing cost.
Tus nqi thiab muab kev txiav txim siab: NM500 ua raws li Suav lub teb chaws tus qauv GB / T24186, muaj cov khoom siv dav dav hauv tsev thiab cov nqi tsim nyog, ua rau nws muaj kev sib tw ntau dua ntawm cov nqi tag nrho, tshwj xeeb tshaj yog rau kev yuav khoom ntau. AR500, ntawm qhov tod tes, feem ntau ua raws li ASTM cov qauv, thiab nws cov saw hlau yog cov concentrated.
Yog tias koj qhov project tsis xav tau cov ntawv pov thawj tshwj xeeb hauv cheeb tsam cuam tshuam nrog AR500, tom qab ntawd hloov mus rau NM500 steel daim hlau yuav yog qhov kev txiav txim siab zoo uas sib npaug kev ua haujlwm thiab tus nqi.
Yog tias koj tab tom nrhiav tus nqi-kev ua tau zoo nrog kev ua tau zoo piv rau AR500, NM500 abrasion- cov hlau tsis zoo yog qhov pov thawj thiab kev xaiv zoo tshaj plaws.

FAQ:
1. Qhov txawv ntawm AR500 thiab NM500 yog dab tsi?
AR500: Cov pa roj carbon ntau (C: ~ 0.38-0.45%), chromium (Cr: ~ 1.5%), thiab boron (B: 0.0005-0.006%) rau kev txhim kho hardness thiab corrosion kuj. NM500: Tsawg carbon (C: Tsawg dua lossis sib npaug rau 0.38%), ntxiv nickel (Ni: Tsawg dua lossis sib npaug li 1.0%) thiab molybdenum (Mo: Tsawg dua lossis sib npaug li 0.65%) rau kev sib npaug weldability thiab toughness.
2. Yuav ua li cas hnav - cov hlau tsis muaj zog yuav raug txiav?
Hnav daim hlau tuaj yeem ua tiav los ntawm kev txiav cov nplaim hluav taws lossis cov plasma. Tshwj xeeb tshaj yog rau NM500, preheating ua ntej txiav thiab qeeb txias tom qab txiav yog qhov yuav tsum tau ua kom tsis txhob ncua kev tawg.
3. NM500 puas tuaj yeem welded?
NM500 yog weldable tab sis xav tau cov txheej txheem vuam nruj. Nws yuav tsum tau preheating ntawm 100-150 degree, sib tw qis - hydrogen vuam cov ntaub ntawv, thiab kom zoo ncej-weld tempering kev kho mob los lav vuam zoo.
4. Qhov twg muaj zog dua, AR500 lossis AR550?
AR550 steel yog ib qho nyuaj tshaj AR500, muab superior tsis kam rau pitting thiab cratering. Qhov ntxiv ~ 50 BHN ua rau pom qhov sib txawv, tshwj xeeb tshaj yog nrog siab - nrawm nrawm.
