P690QL1 Kev Ua Haujlwm Flow
Smelting thiab Casting:
Cov ntaub ntawv raw yog smelted nyob rau hauv ib tug hluav taws xob arc rauv los yog converter, nrog nruj tswj cov tshuaj muaj pes tsawg leeg (xws li, C, Si, Mn, Cr, Ni) kom tau raws li EN 10028-6 tus qauv. Lub molten steel yog refined thiab ces cam khwb cia rau hauv slabs ntawm nruam nruam los xyuas kom meej cov qauv sab hauv thiab tsis txhob muaj qhov tsis xws luag xws li segregation.
Tswj Rolling:
Slabs yog rhuab mus rau 1100-1250℃rau homogenization, ces dov los ntawm multi-pass tswj dov. Rolling kub thiab ceev yog precisely kho kom zoo grain loj thiab txhim kho txhua yam khoom.
Quenching thiab Tempering:
Tom qab dov, lub phaj hlau yog quenched (rhuab rau austenitization kub, ces txias txias nrog dej / roj) los tsim ib tug martensitic qauv. Tom qab ntawd nws yog tempered ntawm 550-650℃kom txo tau cov kev ntxhov siab uas seem, txhim kho toughness, thiab ua tiav qhov xav tau lub zog-tawv tshuav nyiaj li cas.
Kev kho deg thiab txiav:
Lub phaj raug txhaj tshuaj blasting lossis pickling kom tshem tawm cov nplai oxide. Tom qab ntawd nws raug txiav mus rau hauv qhov ntau thiab tsawg ntawm cov nplaim taws, txiav cov ntshav, los yog shearing, nrog ntug trimming kom paub meej qhov tseeb.
Kev soj ntsuam zoo:
Kev tshuaj xyuas zaum kawg suav nrog kev kuaj ultrasonic (rau cov teeb meem sab hauv), kev ntsuas cov cuab yeej cuab tam (tensile, cuam tshuam, hardness), thiab tshuaj muaj pes tsawg leeg tsom xam kom paub meej tias ua raws li cov qauv.
