Melting thiab Casting
Cov txheej txheem pib nrog melting ua tib zoo xaiv raw cov ntaub ntawv nyob rau hauv ib puag ncig ntawm lub cub tawg tswj. Cov tshuaj muaj pes tsawg leeg raug saib xyuas kom ua tiav qhov yuav tsum tau muaj qhov sib npaug ntawm alloy uas txhais tau tias qib. Thaum tag nrho melted thiab homogenized, cov hlau yog cam khwb cia rau hauv ingots los yog nruam cam khwb cia slabs, ua tus thawj semi- tiav zoo.
Kub Rolling
Cov slabs yog reheated rau ib tug meej kub thiab ces raug kub dov. Ntau dhau los ntawm dov mills maj mam txo cov thickness thiab ua cov khoom rau hauv daim hlau. Cov theem no qhia txog qhov tseem ceeb ntawm cov yas deformation, uas ua kom zoo dua cov qauv nplej thiab ua rau cov hlau muaj zog thiab toughness.
Kev kho cua sov
Tom qab dov, daim hlau tau quenching, qhov chaw txias sai hloov cov microstructure mus rau hauv ib qho nyuaj, muaj zog lub xeev. Qhov no yog ua raws li tempering ntawm qhov kub thiab txias los txhim kho toughness, txo cov kev ntxhov siab sab hauv, thiab stabilize cov khoom siv. Kev tswj nruj ntawm lub sijhawm thiab qhov kub thiab txias ua kom muaj kev ua haujlwm zoo ib yam thoob plaws lub phaj.
Tiav thiab Kev Tshuaj Xyuas
Cov kauj ruam kawg suav nrog kev ncaj, tu, thiab kho qhov chaw raws li xav tau. Kev tshuaj xyuas tag nrho, xws li kev kuaj ultrasonic, yog ua los xyuas kom muaj qhov tsis xws luag sab hauv lossis saum npoo. Tsuas yog daim hlau uas ua tau raws li cov qauv xav tau mus rau kev ntim khoom thiab xa khoom.
