Kev Ua Haujlwm
Cov xwm txheej ntawm kev xa khoom
Dej quenched thiab tempered.
Tej kev siv
Cov tsheb hnyav hnyav: chassis, dumper lub cev. Kev tsim kho cranes: booms ofbile cranes. Kev tsim qauv
steelworks: choj, choj Cheebtsam, Cheebtsam rau offshore lug. Cov hlab ntsha siab: ruaj thiab
transportable cia tanks, nkoj. Fais fab nroj tsuag: penstocks, kauv rooj. Khoom siv: nqa thiab mobile
khoom siv. Mining thiab earthmoving khoom: ru tsev txhawb nqa. Agricultural khoom thiab trailers
Kev ua haujlwm
Txias-Kev tsim
Cov hlau yog tsim rau txias- ua raws li kev khoov lossis folding raof > 4 zaug phaj thickness
longitudinal thiab > 3 zaug phaj thickness transverse rau dov directionbsequent stress nyem annealing yog
tuaj yeem ncav cuag qhov kub ntawm 580 degree.
Kub-Forming
Kub- ua kom siab tshaj 580℃yog ua tau. Tom qab quenching thiab tempering yuav tsum tau ua raws li
kev xa khoom.
Milling
Drilling nrog cobalt-alloyed siab-ceev steels HSSCO, txiav ceev yuav tsum yog kwv yees li 17 - 19 m/min. Yog
HSS xyaum siv, nws yuav tsum yog kwv yees li 3 - 5 m/min. txiav ceev yuav tsum yog kwv yees li 3 - 5 m/min.
Nplaim-Txiav
Cov khoom siv kub yuav tsum yog qhov tsawg kawg yog chav tsev kub. Peb pom zoo kom preheating hauv qab no
Qhov kub thiab txias: rau phaj thickness> 40mm txog 100 degree,> 80mm txog 150℃thiab> 100mm txog 175 degree
Vuam
Cov hlau yog tsim rau txhua txoj kev siv vuam. Cov khoom siv temperate yuav tsum tsawg kawg yog chav
kub. Peb pom zoo cov nram qab no preheating kub: rau phaj thicknesses> 20mm mus txog 75 degree
40mm txog 100 degree,> 60mm txog 150℃thiab> 100mm txog 175℃.Interpass kub yuav tsum nyob nruab nrab ntawm
V
150℃-225 degree.
Cov kev taw qhia no tsuas yog cov nqi tsim nyog xwb. Feem ntau cov lus qhia ntawm SSEW 088 yuav tsum tau ua raws li. Tau/s
lub sij hawm yuav tsum nyob nruab nrab ntawm 5 thiab 15s, nyob ntawm seb cov txheej txheem vuam siv. Ib qho kev ntxhov siab tom qab
annealing rau kev tsim kho yuav tsum tau ua nyob rau hauv qhov kub ntawm 530℃- 580℃.
S690QL siv rau dab tsi?
Kev siv suav nrogCov cuab yeej txav hauv av, cov tsheb thauj khoom pov tseg, mobile cranes, drilling rigs, siab - kiv cua ceev, thiab txuas hniav. ASTM A514, EN 10149-2 Qib S700MC, AS / NZS 3579 Qib 700, AM 700, Bisalloy 80. S690QL steel phaj tuaj yeem ua tau yooj yim tsim lossis khoov ntawm chav tsev kub yog tias muaj lub zog txaus thiab siv cov txheej txheem tsim nyog.
Qib twg yog qhov zoo tshaj plaws hauv cov hlau?
1. Carbon Steel (Qib 1018)Cov pa roj carbon steel, tshwj xeeb yog Qib 1018, yog ib qho ntawm feem ntau siv cov qib steel vim nws cov weldability zoo, machinability, thiab pheej yig.
Qhov txawv ntawm Weldox 700 thiab S690QL yog dab tsi?
Qhov ntau yam Weldox 700 qhia tau zoo heev formability thiab tuaj yeem welded raws li cov txheej txheem vuam txheej txheem. Nrog zoo sib xws thiab hardness, qib Strenx S690ql tau txhim kho toughness thiab superior tsis kam tiv thaiv tawg vim kev ntxhov siab.
