S690Q yog European txheem tempered siab zog steel, S690QL steel phaj yog ib tug uas tsis muaj alloy siab zog structural steel phaj.
S690Q / S690QL yog tsim los ntawm hluav taws xob rauv steelmaking los ntawm seem hlau, cov hlau yog ntshiab, cov hlau phaj yog nchuav nrog hlau, txias thiab nias rau hauv cov hlau tiaj tus. Nws yog tiaj, duab plaub, thiab tuaj yeem dov ncaj qha los yog sheared los ntawm dav hlau sawb. Hlau phaj los ntawm thickness, nyias steel phaj<8 mm (the thinnest 0.2 mm), medium-thick steel plate 8 ~ 60 mm, extra-thick steel plate 60 ~ 120 mm.
S690Q / S690QL steel phaj qib qhia:
"S": qhia tias cov hlau phaj yog hlau alloy steel;
"690": qhia tias lub zog ntawm cov hlau phaj yog ntau tshaj 690MPa;
"Q": qhia tias lub xeev xa khoom ntawm cov hlau phaj;
"L": qhov kub ntawm cov hlau phaj yog -50 degree .
S690Q / S690QL steel phaj siv cov qauv: kev ua raws li European tus qauv EN10025-6 tus qauv.
Lub xeev tus me nyuam: steel phaj yog xa nyob rau hauv quenched + tempered mob, los yog lub xeev tus me nyuam tuaj yeem raug teev raws li kev xav tau.
Thickness kev taw qhia kev ua tau zoo: Z15, Z25, Z35.
S690Q / S690QL Kev Xa Khoom: Hlau phaj xa hauv quenched thiab tempered mob.
Cov txheej txheem kev tsim khoom: Cov txheej txheem tsim khoom: Kev tsim kho thawj zaug → LF refining → VD kho → nruam casting (tuag casting) → tu, cua sov → dov → (stacking) → nto tshuaj xyuas → batch → flaw detection → tshav kub kho → txiav kuaj → kev soj ntsuam → lub tsev khaws khoom.
