NM450yog lub siab -lub zog hnav- cov phaj hlau tiv taus nrog lub nominal hardness ntawm 450 HBW. Nws feem ntau muab qhov tsawg kawg nkaus lub zog ntawm 1,100 MPa thiab lub zog tensile tshaj 1,350 MPa, thaum tuav Charpy V-notch cuam tshuam lub zog tsis pub tsawg tshaj 48 J ntawm -40℃.
Qhov kev sib xyaw ua ke ntawm cov tawv tawv thiab cov tawv tawv zoo heev ua rau NM450 kom xa cov kev pabcuam lub neej kwv yees li 3 mus rau 5 npaug ntev dua li cov qauv siv hlau nyob rau hauv tib lub sijhawm ua haujlwm. Tsis tas li ntawd, nws cov pa roj carbon sib npaug (CEV) tsawg dua lossis sib npaug li 0.59% ua kom zoo weldability, yuav tsum tsuas yog nruab nrab preheating rau feem ntau vuam daim ntaub ntawv, yog li ntsuas lub neej ntev kev pab cuam nrog zoo fabricability. NM450 yog dav siv rau siab- hnav, hnyav- lub luag haujlwm xws li mining pob tseg tsheb lub cev, cov thoob excavator, crusher liners, thiab lwm yam puas tsuaj - cov khoom siv hnyav.
Hauv cov khoom siv ib txwm siv rau kev hnav-cov hlau tsis muaj zog, cov khoom siv tseem ceeb- cov hlau tsis muaj zog xws li NM450 feem ntau muab rau ntawm qhov tuab ntawm 6 hli thiab siab dua nrog tus qauv dav ntawm 1500mm. Cov khoom lag luam uas muaj ultra- cov ntsuas me me ua ke nrog qhov siab tshaj plaws txwv qhov dav tau ntev lawm hauv kev lag luam luv luv.
Puas yog koj nkees ntawm welding ntau daim hlau nqaim thiab cuam tshuam qhov ntev? GNEE Steel txuas rau qhov sib txawv no nrog kev npaj - rau - nkoj 3 × 2000 × 6000 NM450. Hu rau peb pab neeg tam sim no kom paub meej tias muaj Tshuag thiab tau txais cov lus sib tw.
NM450 Ultra-Thin Limit-Width Wear-Resistant Steel: Qhov Zoo Li Cas Nws Muaj Ntau Tshaj Li NM450?
Kev ua tau zoo ntawm lub teeb yuag
Cov pa tsheb thauj khoom lub cev thiab cov khoom siv mining lub cev feem ntau yog tsim los ntawm 16-20 mm tuab hnav daim hlau, ua rau lub tsheb hnyav. Hloov lawv nrog 3 hli ultra-nyias, siab tshaj plaws - dav NM450 hnav phaj tuaj yeem txo qhov hnyav ntawm lub tsheb los ntawm kwv yees li 50% piv nrog cov pa tuab NM450 daim hlau, ua kom muaj peev xwm them taus thaum txo cov roj noj thaum thauj.
Qhov Tseem Ceeb Ntev Ntev Kev Pabcuam Lub Neej
Standard NM450 feem ntau muab kev hnav lub neej 3 txog 5 npaug ntev dua li qub qis- alloy structural steel. Los ntawm optimized Cr, Mo thiab Ni microalloying ua ke nrog kev tswj dov thiab quenching & tempering txheej txheem, cov qib ultra- nyias ua tau zoo zog thiab toughness. Raws li kev cuam tshuam loj heev- tej yam kev puas tsuaj nyob rau hauv daim ntawv thov tsuas, nws lub neej kev pab cuam tuaj yeem tshaj 10 npaug ntawm cov qauv hlau, txo qhov zaus ntawm kev txij nkawm.
Mechanical Properties Tshaj Tawm Txog Cov Qauv Hauv Lub Tebchaws - Tsis muaj brittleness hauv Ultra-Thin Gauges
Siv lub 3 hli ultra-nyias NM450 ua piv txwv, tus hwm version yog tsim los rau hauv cov qauv kev tswj xyuas zoo uas muaj qhov nruj dua li qhov yuav tsum tau muaj ntawm GB/T 24186. Nws muab cov tawv tawv ntawm ntau dua lossis sib npaug rau 450 HBW, lub zog tawm los ntawm Ntau dua lossis sib npaug rau 1,150 MPa, sib npaug ntawm lub zog ntau dua los yog sib npaug rau 1,150 MPa. MPa, thiab Charpy V-qhov cuam tshuam lub zog ntawm ntau dua lossis sib npaug ntawm 35 J ntawm -20℃.
Txawm hais tias nws nyias nyias 3 hli tuab, lub phaj siab tswj tau 450 HBW hnav tsis kam thaum ua tiav lub zog ntau dua thiab qis - qhov kub thiab txias. Nws ua tau zoo kov yeej qhov tsis zoo ntawm cov pa nyias nyias, suav nrog kev ua kom brittleness, qis -kub tawg, thiab delamination ntawm qhov chaw nyob rau hauv kev cuam tshuam, muab kev ruaj ntseg zoo dua thiab txhim kho kev tiv thaiv tawg thiab deformation nyob rau hauv qhov chaw txias, siab - kev siv cuam tshuam, thiab kev pabcuam hnyav hnyav.
Zoo heev Flatness thiab Fabrication Performance
Lub phaj ultra- nyias nyias yog tsim los siv siab- precision kub dov ua ke nrog cov txheej txheem hauv online, ua tiav thawj zaug - dhau qhov kev tsim nyog tau txais txiaj ntsig ntawm ntau dua 90% thiab zoo heev phaj flatness. Nws qhov qis-carbon, qis- cov tshuaj lom neeg tsis huv ua kom muaj kev ruaj ntseg thaum lub sij hawm vuam, laser txiav, khoov, thiab lwm yam txheej txheem fabrication, ua kom nws zoo haum rau ntau lawm, tu, thiab refurbishment ntawm kev tsim kho machinery thiab tshwj xeeb tsheb lub cev.

Kev tsim kho tshuab thiab tsheb tshwj xeeb
Tej kev siv: Lub teeb yuag dump truck cargo box liners, tsheb -mounted crane tiv thaiv daim hlau, huv si khib nyiab tsheb sab hauv liners.
Qhov dav ntawm tsheb thauj khoom lub thawv yog feem ntau nyob ib ncig ntawm 2000mm. Lub 2000mm-wide steel phaj tuaj yeem muab tso rau tag nrho yam tsis muaj qhov sib txuas ntev, tshem tawm tag nrho cov kev pheej hmoo ntawm cov khoom xau los ntawm kev hnav- los ntawm cov vuam seams. Piv nrog rau cov tsoos 6 hli - daim hlau tuab, 3 hli specification txiav qhov hnyav ntawm 50%, uas ncaj qha nce load peev xwm thiab txo cov roj noj. Ob qhov zoo no ua tau raws li qhov xav tau ntawm cov tsheb thauj mus los.
-
Cov khoom siv thauj khoom thiab kev tiv thaiv ib puag ncig:Siv conveyor chute guard daim hlau, ntsia hlau conveyor hniav, plua plav tshem tawm cua duct puab liner.
-
