Dab tsi yog qhov hardness ntawm S690QL1steel?
S690QL1 steel, siab -lub zog quenched thiab tempered structural steel, tsis muaj ib tug ruaj hardness yuav tsum tau tab sis feem ntau nthuav tawm Brinell Hardness (BHN) ntau yam ntawmib ncig ntawm 235-295 BHN, txawm hais tias qhov no yog tus nqi raug rau cov ntaub ntawv thiab tsis yog qhov yuav tsum tau ntsuas qhov ntsuas, tsom mus rau nws cov txiaj ntsig siab (690 MPa) thiab zoo heev toughness ntawm qhov kub thiab txias (txog -60 degree) rau kev thov kev thov.
S690QL1 yog tus qauv European (EN 10025-6) siab- lub zog quenched thiab tempered structural steel, paub txog nws qhov tsawg kawg nkaus tawm lub zog ntawm 690 MPa, zoo weldability, thiab zoo heev cuam tshuam toughness ntawm qhov kub thiab txias (txog rau -60℃rau hnyav thiab kev tsim kho), ua rau nws lub tswv yim hnyav-du. lightness thiab lub zog yog qhov tseem ceeb. Lub npe hu ua: 'S' rau cov qauv, '690' rau 690 MPa yield zog, 'Q' rau quenched, 'L' rau normalized (los yog tswj dov), thiab '1' qhia txog qhov tshwj xeeb uas tsis tshua muaj kev cuam tshuam kev ntsuas qhov yuav tsum tau ua.
Hauv thaj av ntawm ntug dej hiav txwv thiab dej hiav txwv engineering, S690QL1 yog qhov tseem ceeb rau kev tsim kho ntawm jack- nce rigs, offshore platforms, thiab cua turbine foundations. Cov qauv no feem ntau raug rau qhov hnyav, corrosive ib puag ncig ntawm lub hiav txwv qhib thiab yuav tsum tiv taus cov dynamic loads ntawm nthwv dej thiab cua. Qhov kev xaiv "L1" yog qhov tseem ceeb ntawm no, vim nws lav tias cov hlau tseem tawv thiab tiv taus cov pob txha tawg txawm tias nyob hauv qhov txias txias ntawm Arctic lossis North Sea dej. Ib yam li ntawd, nyob rau hauv kev lag luam mining thiab earthmoving industries, S690QL1 yog siv rau lub chassis ntawm hnyav- lub luag hauj lwm dump tsheb, excavator thoob, thiab hnav-cov khoom tiv taus. Cov hlau muaj peev xwm nqus tau lub zog thiab tiv thaiv kev cuam tshuam kom ntseeg tau tias cov khoom siv tuaj yeem ua haujlwm tau zoo nyob rau hauv cov kev xav tau tshaj plaws ntawm geological yam tsis muaj kev puas tsuaj loj.
Cov yam ntxwv tseem ceeb:
Siab zog:Yam tsawg kawg nkaus lub zog ntawm 690 MPa (megapascals).
Kev kho cua sov:Xa nyob rau hauv ib qho quenched thiab tempered (Q&T) mob rau kev txhim kho cov khoom.
Tsawg-Tsub Toughness:'L1' txhais tau hais tias nws muaj kev cuam tshuam - kuaj ntawm -60 degree, muab kev ua tau zoo hauv qhov chaw txias piv rau S690QL (-40℃).
Zoo Weldability:Cov hlau ntshiab uas muaj cov ntsiab lus tsis zoo (P, S) ua rau kev ua haujlwm vuam zoo.
Zoo-Grained:Feem ntau tsim nrog kev tswj dov rau kev ua haujlwm siab tshaj plaws.
Kev siv ntau:
Crane (zeeg)
Cov choj thiab cov txheej txheem steelworks
Mining thiab excavation machinery (ru tsev txhawb nqa, pov tseg lub cev)
Heavy- tsheb ua haujlwm (chassis, dumper lub cev)
Offshore cov qauv thiab cov nkoj siab
Lub zog tawm los ntawm S690QL1 yog dab tsi?
S690QL1, siab -lub zog steel, muaj qhov tsawg kawg nkaus tawm lub zog (ReH) ntawm690 MPa rau thicknesses txog 50mm, txo qis rau 650 MPa (50-100mm) thiab 630 MPa (100{6}}150mm), raws li EN 10025-6 tus qauv, kom ntseeg tau tias muaj zog ua haujlwm hauv cov haujlwm hnyav, huab cua txias.
Dab tsi yog qhov yuav tsum tau ua rau kev xeem S690QL1?
Cov kev xav tau kev sim ntau rau S690QL1, siab - lub zog steel qauv, tsom rau nws cov khoom tseem ceeb: yam tsawg kawg nkaus 690 MPa yield zog, 770-940 MPa tensile lub zog, thiab tseem ceeb heev -60℃cuam tshuam toughness (QL1 tsim), txheeb xyuas los ntawm qhov ntev tensile-tshuaj ntsuam xyuas daim hlau, ua kom muaj kev ua tau zoo hauv kev xav tau, qhov chaw txias, nrog rau kev sim feem ntau raws li EN 10025-6 tus qauv.
Txoj kev zoo tshaj plaws los txiav S690QL1 yog dab tsi?
Txoj kev zoo tshaj plaws los txiav S690QL1 nyob ntawm lub phaj thickness thiab qhov yuav tsum tau precision, tab sis Laser Txiav thiab Plasma Txiav yog qhov kev xaiv ntau tshaj plaws. Rau daim hlau mus txog 25 hli, Laser Txiav yog qhov zoo tagnrho vim tias nws muaj qhov ua tau zoo heev thiab qhov nqaim Heat Affected Zone (HAZ), uas pab khaws cov hlau tshwj xeeb quenched thiab tempered zog. Rau cov phaj tuab, High-Txhais Plasma Txiav yog qhov ua tau zoo, muab qhov sib npaug ntawm qhov nrawm thiab tus nqi- ua haujlwm tau zoo. Yog tias koj xav tau kom tsis txhob muaj cua sov tag nrho los xyuas kom meej tias cov neeg kho tshuab kev ncaj ncees ntawm "L1" (tsawg-kub toughness) qib tseem 100% tsis hloov, Abrasive Waterjet Txiav yog qhov zoo tshaj "txias" txoj kev, vim nws tiv thaiv cov thermal softening. Thaum siv cov txheej txheem thermal xws li Oxy- roj, nws yog ib qho tseem ceeb rau preheat thicker daim hlau (feem ntau saum 40mm) mus rau ib ncig ntawm 100℃mus rau 175℃los tiv thaiv ntug tawg.
